| Organization | NOTE A—ORGANIZATION U.S. Silica Holdings, Inc. (“Holdings,” and together with its subsidiaries “we,” “us” or the “Company”), formerly GGC USS Holdings, Inc., was organized as a holding company on November 14, 2008. On November 25, 2008, we acquired Hourglass Acquisitions I, LLC, whose only operating subsidiary was U.S. Silica Company (“U.S. Silica”). On November 25, 2008, we issued 1,000 shares of our common stock to our then sole stockholder, GGC Holdings, for an aggregate purchase price of $10.00. The shares were issued in reliance on Section 4(2) of the Securities Act because the sale of the securities did not involve a public offering. Appropriate legends were affixed to the securities issued in this transaction. On July 8, 2011, our Board of Directors approved, and we subsequently filed, an Amended and Restated Certificate of Incorporation which, among other things, increased the authorized shares of common stock to 100 million shares. The Amended and Restated Certificate of Incorporation also created a 50,000-for-one split of our common stock. All of our common stock share and per share data contained in the financial statements has been retroactively adjusted to reflect this stock split for all periods presented. On January 31, 2012, the Certificate of Incorporation was amended and restated to increase the authorized shares of common stock to 500 million shares, and to authorize 10 million shares of preferred stock. On January 31, 2012, we completed an initial public offering of common stock (the “IPO”) through a Registration Statement on Form S-1 (File No. 333-175636), pursuant to which we registered and issued 2,941,176 shares of our common stock, and we registered and certain of our stockholders sold 8,823,529 shares of common stock at an offering price of $17.00 per share. On February 6, 2012, we issued all 2,941,176 shares of common stock for an aggregate offering price of approximately $50.0 million and the selling stockholders sold all 8,823,529 shares of common stock for an aggregate offering price of approximately $150.0 million. As a result of the offering, we received net proceeds of approximately $40.8 million, after deducting $3.5 million of underwriting discounts and commissions and offering expenses of $5.7 million. On January 31, 2012, simultaneously with the initial public offering of our common stock, GGC USS Holdings, LLC (“GGC Holdings”), our sole stockholder prior to the IPO and now our largest stockholder, contributed to us all of the stock of its wholly-owned subsidiary, GGC RCS Holdings, Inc., and its operating subsidiary, Coated Sand Solutions, LLC. Prior to this transaction, GGC RCS Holdings, Inc. had a $15.0 million note payable to GGC Holdings which, together with accrued interest of $1.7 million, was converted to an equity contribution by GGC Holdings, simultaneously with the IPO. Coated Sand Solutions, LLC owns facilities to produce resin-coated sand. |

| Summary of Significant Accounting Policies | NOTE B—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The consolidated financial statements as of and for the three and nine months ended September 30, 2013 and 2012 (the “Financial Statements”), present our financial position, results of operations, and cash flows. In consideration of the contribution of GGC RCS Holdings, Inc. to us on January 31, 2012, we and our subsidiaries are presented on a consolidated basis with GGC RCS Holdings, Inc. as of and for the three and nine months ended September 30, 2013 and 2012 and as of the year ended December 31, 2012. We have condensed or omitted certain information and footnote disclosures normally included in financial statements presented in accordance with U.S. generally accepted accounting principles (“GAAP”). Although we believe our disclosures are adequate to make the information presented not misleading, you should read the Financial Statements in this report in conjunction with the combined financial statements and notes to those financial statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012, as filed with the Securities and Exchange Commission (“SEC”) on February 26, 2013 (our “2012 Annual Report”). Certain terms not otherwise defined in this Quarterly Report on Form 10-Q have the meanings specified in our 2012 Annual Report. In our opinion, our Financial Statements reflect all normal and recurring adjustments necessary to present fairly our financial position as of September 30, 2013, and December 31, 2012, the results of our operations for the three and nine months ended September 30, 2013 and 2012, and our cash flows for the nine months ended September 30, 2013 and 2012. Interim results may not be indicative of fiscal year performance because of seasonal and short-term variations. We have eliminated all material intercompany transactions and balances between entities consolidated in these Financial Statements. We follow Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) guidance for identification and reporting of entities over which control is achieved through means other than voting rights. The guidance defines such entities as Variable Interest Entities (“VIEs”). As of September 30, 2013 and for the periods presented herein, we have identified no entities over which we maintain any level of control that would qualify for consolidation under ASC guidance. In order to make this report easier to read, we refer throughout to (i) our Condensed Consolidated Balance Sheets as our “Balance Sheets,” (ii) our Condensed Consolidated Statements of Operations as our “Income Statements,” and (iii) our Condensed Consolidated Statements of Cash Flows as our “Cash Flows.” Unaudited Interim Financial Statements The accompanying Balance Sheet as of September 30, 2013, the Income Statements for the three and nine months ended September 30, 2013 and 2012; the Consolidated Statements of Comprehensive Income for the three and nine months ended September 30, 2013 and 2012; the Consolidated Statements of Cash Flows for the nine months ended September 30, 2013 and 2012; and other information disclosed in the related notes are unaudited. The Balance Sheet as of December 31, 2012 was derived from our audited consolidated financial statements as included in our 2012 Annual Report. The accompanying Financial Statements should be read in conjunction with the audited combined financial statements and related notes contained in our 2012 Annual Report. Use of Estimates The preparation of the Financial Statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of the Financial Statements and the reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to mineral reserves that are the basis for future cash flow estimates utilized in impairment calculations and units-of-production amortization calculations; environmental, reclamation and closure obligations; estimates of recoverable minerals; estimates of fair value for certain reporting units and asset impairments (including impairments of goodwill and other long-lived assets); write-downs of inventory to net realizable value; post-employment, post-retirement and other employee benefit liabilities; valuation allowances for deferred tax assets; reserves for contingencies and litigation; and the fair value and accounting treatment of financial instruments including derivative instruments. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results may differ significantly from these estimates under different assumptions or conditions. Recently Adopted Accounting Pronouncements In May 2011, the FASB issued changes to conform existing guidance regarding fair value measurement and disclosure between GAAP and International Financial Reporting Standards. These changes both clarify the FASB’s intent about the application of existing fair value measurement and disclosure requirements and amend certain principles or requirements for measuring fair value or for disclosing information about fair value measurements. The clarifying changes relate to the application of the highest and best use and valuation premise concepts, measuring the fair value of an instrument classified in a reporting entity’s stockholders’ equity, and disclosure of quantitative information about unobservable inputs used for Level 3 fair value measurements. The amendments relate to measuring the fair value of financial instruments that are managed within a portfolio; application of premiums and discounts in a fair value measurement; and additional disclosures concerning the valuation processes used and sensitivity of the fair value measurement to changes in unobservable inputs for those items categorized as Level 3, a reporting entity’s use of a nonfinancial asset in a way that differs from the asset’s highest and best use, and the categorization by level in the fair value hierarchy for items required to be measured at fair value for disclosure purposes only. We adopted this guidance, effective January 1, 2012, with no material impact on our Financial Statements. In June 2011, the FASB issued changes to the presentation of comprehensive income. These changes give an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements; the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity was eliminated. The items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income were not changed. Additionally, no changes were made to the calculation and presentation of earnings per share. We adopted this guidance, effective January 1, 2012, with no material impact on our Financial Statements. In September 2011, the FASB issued changes to the testing of goodwill for impairment. These changes provide an entity the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (more than 50%) that the fair value of a reporting unit is less than its carrying amount. Such qualitative factors may include the following: macroeconomic conditions; industry and market considerations; cost factors; overall financial performance; and other relevant entity-specific events. If an entity elects to perform a qualitative assessment and determines that an impairment is more likely than not, the entity is then required to perform the existing two-step quantitative impairment test, otherwise no further analysis is required. An entity also may elect not to perform the qualitative assessment and, instead, go directly to the two-step quantitative impairment test. We adopted this guidance, effective January 1, 2012 with no material impact on our Financial Statements. In September 2011, the FASB issued changes to increase the level of disclosure about an employer’s participation in a multiemployer pension plan. These changes require that employers provide additional separate quantitative and qualitative disclosures for multiemployer pension plans and multiemployer other post-retirement benefit plans, including the significant multiemployer plan(s) in which an employer participates, the level at which an employer participates in the plan(s), the financial health of the plan(s) and the nature of the employer commitments to the plan(s). We adopted this guidance, effective January 1, 2012 with no material impact on our Financial Statements. In July 2012, the FASB issued changes to the testing of indefinite-lived intangible assets for impairment. These changes provide an entity the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (more than 50%) that the fair value of an indefinite-lived intangible asset is less than its carrying amount. In accordance with the amendment, an entity has the option first to assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired. In conducting a qualitative assessment, an entity should consider the extent to which relevant events and circumstances, both individually and in the aggregate, could have affected the significant inputs used to determine the fair value of the indefinite-lived intangible asset since the last assessment. If, after assessing the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount. An entity also has the option to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to performing the quantitative impairment test. An entity will be able to resume performing the qualitative assessment in any subsequent period. We adopted this guidance, effective for the 2012 reporting period with no material impact on our Financial Statements. In February 2013, the FASB issued ASU 2013-02, “Comprehensive Income (“ASC Topic 220”): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which requires entities to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, entities are required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, entities are required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail on these amounts. We adopted this guidance, effective for the 2013 reporting period with no material impact on our Financial Statements. In July 2013, the FASB amended Accounting Standards Codification (“ASC Topic 740”), “Income Taxes.” The amendment provides guidance on the financial statement presentation of an unrecognized tax benefit, as either a reduction of a deferred tax asset or as a liability, when a net operating loss carry-forward, a similar tax loss or a tax credit carry-forward exists. The amendment will be effective for interim and annual periods beginning after December 15, 2013 and may be applied on a retrospective basis. Early adoption is permitted. We do not expect the adoption of this amendment to have a significant effect on our consolidated financial position or results of operations. |

| Earnings Per Share | NOTE C—EARNINGS PER SHARE Basic income per common share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted income per common share is computed similarly to basic income per common share except that the weighted average number of common shares outstanding is increased to include the number of additional common shares that would have been outstanding if the potentially dilutive common shares had been issued. In accordance with the applicable accounting guidance for calculating earnings per share, we did not include in our calculation of diluted earnings per share for the applicable periods stock options where the exercise prices were greater than the average market prices. The weighted average outstanding stock options excluded were (in thousands) 193 and 169 for the three and nine months ended September 30, 2013, respectively, and 1,384 and 998 for the three and nine months ended September 30, 2012.

| Capital Structure and Accumulated Comprehensive Income | NOTE D—CAPITAL STRUCTURE AND ACCUMULATED COMPREHENSIVE INCOME
Common Stock Our Amended and Restated Certificate of Incorporation authorizes up to 500,000,000 shares of common stock, par value of $0.01. Subject to the rights of holders of any series of preferred stock, all of the voting power of the stockholders of Holdings shall be vested in the holders of the common stock. There were 53,384,264 shares of common stock issued and outstanding at September 30, 2013. As of September 30, 2012, there were 52,843,176 shares issued and outstanding. On July 29, 2013, our Board of Directors declared a quarterly cash dividend of $0.125 per share to common stockholders of record at the close of business on September 19, 2013, payable on October 3, 2013. Management and our Board of Directors remain committed to evaluating additional ways of creating shareholder value. Any determination to pay dividends and other distributions in cash, stock, or property by Holdings in the future will be at the discretion of our Board of Directors and will be dependent on then-existing conditions, including our business conditions, our financial condition, results of operations, liquidity, capital requirements, contractual restrictions including restrictive covenants contained in our debt agreements, and other factors. Additionally, because we are a holding company, our ability to pay dividends on our common stock may be limited by restrictions on the ability of our subsidiaries to pay dividends or make distributions to us, including restrictions under the terms of the agreements governing our indebtedness. Preferred Stock Our Amended and Restated Certificate of Incorporation authorizes our Board of Directors to issue up to 10,000,000 shares, in the aggregate, of preferred stock, par value of $0.01 in one or more series and to fix the preferences, powers and relative, participating, optional or other special rights and qualifications, limitations or restrictions thereof, including the dividend rate, conversion rights, voting rights, redemption rights and liquidation preference and to fix the number of shares to be included in any such series without any further vote or action by our stockholders. There are no shares of preferred stock issued or outstanding at September 30, 2013 and 2012. At present, we have no plans to issue any preferred stock. Share Repurchase Program On June 11, 2012, our Board of Directors authorized us to repurchase up to $25.0 million of our common stock.

| Debt Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Debt | NOTE I—DEBT As discussed below, on July 23, 2013, we refinanced our existing senior secured debt by amending our Term Loan and replacing our existing Revolver. At September 30, 2013 and December 31, 2012, debt consisted of the following:
Revolving Line-of-Credit As of September 30, 2013, the available borrowing base under our revolving line-of-credit (the “Revolver”) was $50 million, with zero drawn as of that date and $9.3 million allocated for letters of credit, leaving $40.7 million available for general corporate use under this revolving credit agreement.
Debt Maturities As of September 30, 2013, contractual maturities of our debt are as follows:
On January 31, 2012, we amended our senior secured term loan facility (the “Term Loan”). The primary revisions to the Term Loan were to eliminate a requirement to provide monthly financial reports, to remove financial covenant restrictions related to capital expenditures, to provide flexibility to make investments and acquisitions and to incur indebtedness, and to provide a new subsidiary guarantee from Coated Sand Solutions, LLC. On December 31, 2012, we amended our Revolver. The primary revisions to the Revolver included an increase of the commitment under the Revolver from $35 million to $50 million, and the letter of credit sublimit from $15 million to $20 million; provided, however, that the aggregate principal amount of the loans and letters of credit obligations outstanding at any one time shall not exceed the borrowing base as calculated pursuant to the agreement. The amendment also extended the termination date of the Revolver from October 31, 2015 to October 31, 2016, reduced prices and fees on borrowings, letters of credit and unused commitments and added an additional subsidiary, Coated Sand Solutions, LLC, as a co-borrower. On July 23, 2013, we refinanced our existing senior secured debt by amending our Term Loan and replacing our existing Revolver. The Term Loan amendment refinanced our existing senior debt by entering into a new $425 million senior secured credit facility, consisting of a $375 million Term Loan and a $50 million new Revolver that may also be used for swingline loans (up to $5 million) or letters of credit (up to $20 million). The Term Loan amendment also, among other things, removed and amended certain financial and other covenants to provide additional operating flexibility, and lowered interest rates on borrowed amounts. The existing Revolver was terminated. The Term Loan will expire on July 23, 2020 and the new Revolver will expire on July 23, 2018. As a result of refinancing our Term Loan and replacing our Revolver, we expensed $1.6 million of costs consisting of $1.1 million related to third party fees in selling, general, and administrative expenses and $0.5 million related to early extinguishment of debt. Our senior secured credit facility is secured by substantially all of our assets and a pledge of the equity interests in certain of our subsidiaries. The facility contains covenants that, among other things, govern our ability to create, incur or assume indebtedness and liens, to make acquisitions or investments, to pay dividends and to sell assets. The facility also requires us to maintain a consolidated leverage ratio of no more than 3.75:1.00 as of the last day of any fiscal quarter whenever usage of the Revolver (other than certain undrawn letters of credit) exceeds 25% of the Revolver commitment. As of September 30, 2013, we are in compliance with all covenants in accordance with our senior secured credit facility. |

| Fair Value Accounting | NOTE K—FAIR VALUE ACCOUNTING Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Cash equivalents Due to the short-term maturity, we believe that our cash equivalent instruments at September 30, 2013 and December 31, 2012 approximate their reported carrying values. Short-Term Investments In general, the fair value of our short-term investments is based on quoted prices for similar assets in active markets, or for identical assets or similar assets in markets in which there were fewer transactions. Money market mutual funds are based on calculated net asset value. Variable rate demand obligations underwritten and remarketed by a financial institution are priced at par value. Long-Term Debt, including current maturities We believe that the fair values of our long-term debt, including current maturities, approximate their carrying values and based on their effective interest rates compared to current market rates. Derivative Instruments The estimated fair value of our derivative assets (interest rate caps) are recorded at each reporting period and are based upon widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative contract. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. We also incorporate credit valuation adjustments to appropriately reflect both our nonperformance risk as well as that of the respective counterparty in the fair value measurements. Although we have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by us and our counterparties. However, as of September 30, 2013, we have assessed that the impact of the credit valuation adjustments on the overall valuation of our derivative positions is not significant. As a result, we have determined that our derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. In accordance with the fair value hierarchy, the following table presents the fair value of those assets that we measure at fair value on a recurring basis:

| Derivative Instruments And Hedging Activities Disclosure [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Derivative Instruments | NOTE M—DERIVATIVE INSTRUMENTS We are exposed to certain risks arising from both our business operations and economic conditions. We principally manage our exposure to a wide variety of business and operation risks through management of our core business activities. Specifically, we enter into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and unknown cash amounts, the value of which are determined by current interest rates. Interest rate derivatives are utilized in the normal course of business to manage our interest cost and the risk associated with changing interest rates. We do not use derivative financial instruments for trading or speculative purposes. By their nature, all such instruments involve risk, including the possibility that a loss may occur from the failure of another party to perform according to the terms of a contract (credit risk) or the possibility that future changes in market price may make a financial instrument less valuable or more onerous (market risk). As is customary for these types of instruments, we do not require collateral or other security from other parties to these instruments. In management’s opinion, there is no significant risk of loss in the event of nonperformance of the counterparties to these financial instruments. Cash Flow Hedges of Interest Rate Risk Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements. To accomplish this objective, we primarily use interest rate cap agreements as part of our interest rate risk management strategy. Interest rate caps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an upfront premium.
In connection with the Term Loan, we entered into two interest rate cap agreements that effectively place an upper limit for one-month LIBOR at 4.0% on the interest rate charged for $130.0 million of our floating rate Term Loan. On March 31, 2012, one of the agreements with a notional amount of $100.0 million matured. Concurrently with the maturity, the notional amount of a second agreement with an original notional amount of $30.0 million automatically increased to $130.0 million per the terms of the contract. On June 30, 2013 the second agreement matured. No additional expense was reclassified from accumulated other comprehensive income or recognized directly in earnings as a result of the maturity or adjustment. We entered into two interest rate cap agreements on April 8, 2013 and September 6, 2013 with a notional amount of $128 million and $60 million, respectively, which effectively place an upper limit for three-month LIBOR at 4.0%. We assess the effectiveness of our hedges in offsetting the variability in the cash flow of the hedged obligations on a quarterly basis. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in equity as accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. During the nine months ended September 30, 2013 and the year ended December 31, 2012, we had no ineffectiveness for such contracts. The following table summarizes the fair value of our derivative instruments. See Note K on fair value accounting for additional disclosures regarding the estimated fair values of our derivative instruments at September 30, 2013 and December 31, 2012.
We have designated these contracts as qualified cash flow hedges. Accordingly, the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income and recognized in earnings in the same period or periods during which the hedged transaction affects earnings. The following table summarizes the effect of our derivatives instruments on our income statements and our condensed consolidated statements of comprehensive income for the three and nine months ended September 30, 2013 and 2012.

| Disclosure Of Compensation Related Costs Sharebased Payments [Abstract] | |
| Equity-Based Compensation | NOTE N—EQUITY-BASED COMPENSATION We recognize the cost of employee services rendered in exchange for awards of equity instruments, such as stock options and restricted stock, based on the fair value of those awards at the date of the grant. Compensation expense for equity units is recognized, on a straight-line basis, net of forfeitures, over the requisite service period for the fair value of the awards that actually vest.
As of September 30, 2013, we maintain two equity incentive plans (i) the GGC USS Holdings, LLC Management Equity Program (the “Equity Program”), and (ii) the U.S. Silica Holdings, Inc. 2011 Incentive Compensation Plan (the “2011 Plan”). The Equity Program granted Class C and Class D member units in GGC Holdings to three members of executive management; one of whom continues to be employed by us at September 30, 2013. The 2011 Plan provides for grants of stock options, stock appreciation rights, restricted stock and other incentive-based awards. For awards granted under the Equity Program, we recognized $27 and $55 of compensation expense during the three months ended September 30, 2013 and 2012, respectively, and $82 and $164 during the nine months ended September 30, 2013 and 2012, respectively. As of September 30, 2013, there was $119 of total unrecognized compensation expense related to equity incentive shares, which is expected to be recognized over a weighted-average period of approximately 1.08 years. For awards granted under the 2011 Plan, we recognized $827 and $459 of compensation expense during the three months ended September 30, 2013 and 2012, respectively and $2,154 and $1,498 during the nine months ended September 30, 2013 and 2012, respectively. As of September 30, 2013, there was $7.0 million of total unrecognized compensation expense related to equity incentive awards, which is expected to be recognized over a weighted-average period of approximately 2.63 years. |

| Commitments And Contingencies Disclosure [Abstract] | |
| Commitments and Contingencies | NOTE P—COMMITMENTS AND CONTINGENCIES Our operating subsidiary, U.S. Silica Company (“U.S. Silica”), has been named as a defendant in various product liability claims alleging silica exposure causing silicosis. During the nine months ended September 30, 2013, three new claims were brought against U.S. Silica. As of September 30, 2013, there were 93 active silica-related products liability claims pending in which U.S. Silica is a defendant. Although the outcomes of these claims cannot be predicted with certainty, in the opinion of management, the ultimate resolution of these matters will not have a material adverse effect on our financial position or results of operations. For periods prior to 1986, U.S. Silica had numerous insurance policies and an indemnity from a former owner that covered silicosis claims. In the fourth quarter of 2012, U.S. Silica settled all rights under the indemnity and its underlying insurance policies receiving $5.1 million from the parties involved. As a result of the settlement, the indemnity and related policies are no longer available to U.S. Silica and U.S. Silica will not seek reimbursement for any defense costs or claim payments. Other insurance policies, however, continue to remain available to U.S. Silica. We have recorded estimated liabilities for these claims in other long-term obligations as well as estimated recoveries under the indemnity agreement and an estimate of future recoveries under insurance in other assets on our consolidated balance sheets. As of September 30, 2013 and December 31, 2012, other noncurrent assets included $247 for insurance for third-party products liability claims and other long-term obligations included $1.2 million and $1.3 million, respectively, in third-party products claim liability. |

| Income Tax Disclosure [Abstract] | |
| Income Taxes | NOTE Q—INCOME TAXES We evaluate our deferred tax assets periodically to determine if valuation allowances are required. Ultimately, the realization of deferred tax assets is dependent upon generation of future taxable income during those periods in which temporary differences become deductible and/or credits can be utilized. To this end, management considers the level of historical taxable income, the scheduled reversal of deferred tax liabilities, tax-planning strategies and projected future taxable income. Based on these considerations, and the carry-forward availability of a portion of the deferred tax assets, management believes it is more likely than not that we will realize the benefit of the deferred tax assets. At the end of each reporting period as presented, there were no material amounts of interest and penalties recognized in the statement of operations or balance sheets. We have no material unrecognized tax benefits or any known material tax contingencies at September 30, 2013 and December 31, 2012. Tax returns filed with the IRS for the years 2010 through 2012 along with tax returns filed with numerous state entities remain subject to examination. In accordance with generally accepted accounting principles, it is our practice at the end of each interim reporting period to make our best estimate of the effective tax rate expected to be applicable for the full fiscal year. Estimates are revised as additional information becomes available. The largest permanent item in computing both our effective tax rate and taxable income is the deduction allowed for statutory depletion. The deduction for statutory depletion does not necessarily change proportionately to changes in income before income taxes. We are evaluating the potential impact of the final regulations released on September 13, 2013 concerning amounts paid to acquire, produce or improve tangible property and recovery of basis upon disposition. Because the revenue procedures governing the tangible property regulations will not be issued until the fourth quarter or later, we are still determining whether or not any changes in accounting method will be required and if they will result in a material impact to our financial statements. At this time, we do not anticipate there being a material impact. |

| Obligations Under Guarantees | NOTE S—OBLIGATIONS UNDER GUARANTEES We have indemnified St. Paul Travelers (“Travelers”) against any loss Travelers may incur in the event that holders of surety bonds, issued on our behalf by Travelers, execute the bonds. As of September 30, 2013, Travelers had $7.4 million in bonds outstanding for us. The majority of these bonds ($7.2 million) relate to reclamation requirements issued by various governmental authorities. Reclamation bonds remain outstanding until the mining area is reclaimed and the authority issues a formal release. The remaining bonds relate to such indefinite purposes as licenses, permits, and tax collection. We have indemnified Safeco Insurance Company of America (“Safeco”) against any loss Safeco may incur in the event that holders of surety bonds, issued on our behalf by Safeco, execute the bonds. As of September 30, 2013, Safeco had $513 in bonds outstanding for us. These are all reclamation bonds. U.S. Silica is the contingent guarantor of Kanawha Rail Corporation’s (“KRC”) obligations as lessee of 199 covered hopper railroad cars, which are used by U.S. Silica to ship sand to its customers. KRC’s obligation as lessee includes paying monthly rent of $66 until June 30, 2015, maintaining the cars, paying for any cars damaged or destroyed, and indemnifying all other parties to the lease transaction against liabilities including any loss of certain tax benefits. By separate agreement between U.S. Silica and KRC, KRC may, upon the occurrence of certain events, assign the lease obligations to U.S. Silica, but none of these events have occurred. |

| Related Party Transactions | NOTE T—RELATED PARTY TRANSACTIONS Advisory Agreement In connection with our acquisition by an affiliate of Golden Gate Capital (the “Golden Gate Capital Acquisition”), we entered into an Advisory Agreement with Golden Gate Capital (the “Advisory Agreement”) whereby Golden Gate Capital agreed to provide business and organizational strategy and financial and advisory services. Such services included support and assistance to management with respect to negotiating and analyzing acquisitions and divestitures, negotiating and analyzing financing alternatives, preparing financial projections, monitoring compliance with financing agreements, marketing functions and searching for and hiring management personnel. As compensation for these services, we agreed to pay Golden Gate Capital (1) an annual advisory fee in the aggregate amount equal to $1.3 million, payable quarterly in arrears, and (2) a transaction fee of 1.25% of the aggregate value of each transaction resulting in a change in control of GGC Holdings or its subsidiaries, along with each acquisition, divestiture, recapitalization and financing. In addition to the fees described above, we also reimbursed Golden Gate Capital for all out-of-pocket costs incurred by Golden Gate Capital in connection with its activities under the Advisory Agreement, and indemnified Golden Gate Capital from and against all losses, claims, damages and liabilities related to the performance of its duties under the Advisory Agreement. On February 6, 2012, we paid $8.0 million to Golden Gate Capital to terminate the advisory agreement previously entered into in connection with the Golden Gate Capital Acquisition. The $8.0 million termination fee was accrued for at December 31, 2011 and no additional expense was recognized during the year ended December 31, 2012 or as of the three and nine months ended September 30, 2013. Promissory Note On December 22, 2010, GGC RCS Holdings, Inc., entered into a $15.0 million promissory note with GGC Holdings, our sole stockholder prior to the IPO and now largest stockholder. The note provided working capital for a new subsidiary and was scheduled to mature on December 22, 2015. The note bore interest at 10%. Outstanding principal and interest under the note was payable upon demand, but no later than the maturity date. Upon sole election by the parent, any unpaid interest could be paid in cash on December 22 of each year until the maturity date. Interest on the note was recorded in interest expense in the Income Statements and any unpaid interest was included in accrued interest on the Balance Sheets. On January 31, 2012, simultaneously with the IPO, GGC Holdings contributed to us all of the stock of GGC RCS Holdings, Inc. and converted the $15.0 million promissory note, including $1.7 million of accrued interest, to equity. |

| Segment Reporting | NOTE U—SEGMENT REPORTING Our business is organized into two reportable segments, Oil & Gas Proppants and Industrial & Specialty Products, based on end markets. The reportable segments are consistent with how management views the markets that we serve and the financial information reviewed by the chief operating decision maker. We manage our Oil & Gas Proppants and Industrial & Specialty Products businesses as components of an enterprise for which separate information is available and is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and assess performance. An operating segment’s performance is primarily evaluated based on segment contribution margin, which excludes certain corporate costs not associated with the operations of the segment. These corporate costs are separately stated below and include costs that are related to functional areas such as operations management, corporate purchasing, accounting, treasury, information technology, legal and human resources. We believe that segment contribution margin, as defined above, is an appropriate measure for evaluating the operating performance of our segments. However, this measure should be considered in addition to, not a substitute for, or superior to, income from operations or other measures of financial performance prepared in accordance with generally accepted accounting principles. The other accounting policies of each of the two reporting segments are the same as those in the summary of significant accounting policies included in Note B. In the Oil & Gas Proppants segment, we serve the oil and gas recovery market providing fracturing sand, or “frac sand,” which is pumped down oil and natural gas wells to prop open rock fissures and increase the flow rate of natural gas and oil from the wells. The Industrial & Specialty Products segment consists of over 250 products and materials used in a variety of industries including, container glass, fiberglass, specialty glass, flat glass, building products, fillers and extenders, foundry products, chemicals, recreation products and filtration products.
The following table presents sales and segment contribution margin for the reporting segments and other operating results not allocated to the reported segments for the three and nine months ended September 30, 2013 and 2012:
Asset information, including capital expenditures and depreciation, depletion, and amortization, by segment is not included in reports used by management in its monitoring of performance and, therefore, is not reported by segment. As of September 30, 2013 and December 31, 2012, goodwill of $68.4 million has been allocated to these segments with $47.7 million assigned to Oil & Gas Proppants and $20.7 million to Industrial and Specialty Products. |

| Basis of Presentation | Basis of Presentation The consolidated financial statements as of and for the three and nine months ended September 30, 2013 and 2012 (the “Financial Statements”), present our financial position, results of operations, and cash flows. In consideration of the contribution of GGC RCS Holdings, Inc. to us on January 31, 2012, we and our subsidiaries are presented on a consolidated basis with GGC RCS Holdings, Inc. as of and for the three and nine months ended September 30, 2013 and 2012 and as of the year ended December 31, 2012. We have condensed or omitted certain information and footnote disclosures normally included in financial statements presented in accordance with U.S. generally accepted accounting principles (“GAAP”). Although we believe our disclosures are adequate to make the information presented not misleading, you should read the Financial Statements in this report in conjunction with the combined financial statements and notes to those financial statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012, as filed with the Securities and Exchange Commission (“SEC”) on February 26, 2013 (our “2012 Annual Report”). Certain terms not otherwise defined in this Quarterly Report on Form 10-Q have the meanings specified in our 2012 Annual Report. In our opinion, our Financial Statements reflect all normal and recurring adjustments necessary to present fairly our financial position as of September 30, 2013, and December 31, 2012, the results of our operations for the three and nine months ended September 30, 2013 and 2012, and our cash flows for the nine months ended September 30, 2013 and 2012. Interim results may not be indicative of fiscal year performance because of seasonal and short-term variations. We have eliminated all material intercompany transactions and balances between entities consolidated in these Financial Statements. We follow Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) guidance for identification and reporting of entities over which control is achieved through means other than voting rights. The guidance defines such entities as Variable Interest Entities (“VIEs”). As of September 30, 2013 and for the periods presented herein, we have identified no entities over which we maintain any level of control that would qualify for consolidation under ASC guidance.
In order to make this report easier to read, we refer throughout to (i) our Condensed Consolidated Balance Sheets as our “Balance Sheets,” (ii) our Condensed Consolidated Statements of Operations as our “Income Statements,” and (iii) our Condensed Consolidated Statements of Cash Flows as our “Cash Flows.” |
| Unaudited Interim Financial Statements | Unaudited Interim Financial Statements The accompanying Balance Sheet as of September 30, 2013, the Income Statements for the three and nine months ended September 30, 2013 and 2012; the Consolidated Statements of Comprehensive Income for the three and nine months ended September 30, 2013 and 2012; the Consolidated Statements of Cash Flows for the nine months ended September 30, 2013 and 2012; and other information disclosed in the related notes are unaudited. The Balance Sheet as of December 31, 2012 was derived from our audited consolidated financial statements as included in our 2012 Annual Report. The accompanying Financial Statements should be read in conjunction with the audited combined financial statements and related notes contained in our 2012 Annual Report. |
| Use of Estimates | Use of Estimates The preparation of the Financial Statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of the Financial Statements and the reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to mineral reserves that are the basis for future cash flow estimates utilized in impairment calculations and units-of-production amortization calculations; environmental, reclamation and closure obligations; estimates of recoverable minerals; estimates of fair value for certain reporting units and asset impairments (including impairments of goodwill and other long-lived assets); write-downs of inventory to net realizable value; post-employment, post-retirement and other employee benefit liabilities; valuation allowances for deferred tax assets; reserves for contingencies and litigation; and the fair value and accounting treatment of financial instruments including derivative instruments. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results may differ significantly from these estimates under different assumptions or conditions. |
| Recently Adopted Accounting Pronouncements | Recently Adopted Accounting Pronouncements In May 2011, the FASB issued changes to conform existing guidance regarding fair value measurement and disclosure between GAAP and International Financial Reporting Standards. These changes both clarify the FASB’s intent about the application of existing fair value measurement and disclosure requirements and amend certain principles or requirements for measuring fair value or for disclosing information about fair value measurements. The clarifying changes relate to the application of the highest and best use and valuation premise concepts, measuring the fair value of an instrument classified in a reporting entity’s stockholders’ equity, and disclosure of quantitative information about unobservable inputs used for Level 3 fair value measurements. The amendments relate to measuring the fair value of financial instruments that are managed within a portfolio; application of premiums and discounts in a fair value measurement; and additional disclosures concerning the valuation processes used and sensitivity of the fair value measurement to changes in unobservable inputs for those items categorized as Level 3, a reporting entity’s use of a nonfinancial asset in a way that differs from the asset’s highest and best use, and the categorization by level in the fair value hierarchy for items required to be measured at fair value for disclosure purposes only. We adopted this guidance, effective January 1, 2012, with no material impact on our Financial Statements. In June 2011, the FASB issued changes to the presentation of comprehensive income. These changes give an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements; the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity was eliminated. The items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income were not changed. Additionally, no changes were made to the calculation and presentation of earnings per share. We adopted this guidance, effective January 1, 2012, with no material impact on our Financial Statements. In September 2011, the FASB issued changes to the testing of goodwill for impairment. These changes provide an entity the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (more than 50%) that the fair value of a reporting unit is less than its carrying amount. Such qualitative factors may include the following: macroeconomic conditions; industry and market considerations; cost factors; overall financial performance; and other relevant entity-specific events. If an entity elects to perform a qualitative assessment and determines that an impairment is more likely than not, the entity is then required to perform the existing two-step quantitative impairment test, otherwise no further analysis is required. An entity also may elect not to perform the qualitative assessment and, instead, go directly to the two-step quantitative impairment test. We adopted this guidance, effective January 1, 2012 with no material impact on our Financial Statements. In September 2011, the FASB issued changes to increase the level of disclosure about an employer’s participation in a multiemployer pension plan. These changes require that employers provide additional separate quantitative and qualitative disclosures for multiemployer pension plans and multiemployer other post-retirement benefit plans, including the significant multiemployer plan(s) in which an employer participates, the level at which an employer participates in the plan(s), the financial health of the plan(s) and the nature of the employer commitments to the plan(s). We adopted this guidance, effective January 1, 2012 with no material impact on our Financial Statements. In July 2012, the FASB issued changes to the testing of indefinite-lived intangible assets for impairment. These changes provide an entity the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (more than 50%) that the fair value of an indefinite-lived intangible asset is less than its carrying amount. In accordance with the amendment, an entity has the option first to assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired. In conducting a qualitative assessment, an entity should consider the extent to which relevant events and circumstances, both individually and in the aggregate, could have affected the significant inputs used to determine the fair value of the indefinite-lived intangible asset since the last assessment. If, after assessing the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount. An entity also has the option to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to performing the quantitative impairment test. An entity will be able to resume performing the qualitative assessment in any subsequent period. We adopted this guidance, effective for the 2012 reporting period with no material impact on our Financial Statements. In February 2013, the FASB issued ASU 2013-02, “Comprehensive Income (“ASC Topic 220”): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which requires entities to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, entities are required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, entities are required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail on these amounts. We adopted this guidance, effective for the 2013 reporting period with no material impact on our Financial Statements. In July 2013, the FASB amended Accounting Standards Codification (“ASC Topic 740”), “Income Taxes.” The amendment provides guidance on the financial statement presentation of an unrecognized tax benefit, as either a reduction of a deferred tax asset or as a liability, when a net operating loss carry-forward, a similar tax loss or a tax credit carry-forward exists. The amendment will be effective for interim and annual periods beginning after December 15, 2013 and may be applied on a retrospective basis. Early adoption is permitted. We do not expect the adoption of this amendment to have a significant effect on our consolidated financial position or results of operations. |

| Earnings Per Share [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Schedule of Basic and Diluted Earnings Per Share | Basic income per common share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted income per common share is computed similarly to basic income per common share except that the weighted average number of common shares outstanding is increased to include the number of additional common shares that would have been outstanding if the potentially dilutive common shares had been issued. In accordance with the applicable accounting guidance for calculating earnings per share, we did not include in our calculation of diluted earnings per share for the applicable periods stock options where the exercise prices were greater than the average market prices. The weighted average outstanding stock options excluded were (in thousands) 193 and 169 for the three and nine months ended September 30, 2013, respectively, and 1,384 and 998 for the three and nine months ended September 30, 2012.
