                            PROXY STATEMENT
            ANNUAL MEETING OF SHAREHOLDERS -- June 5, 1997

     This Proxy Statement is furnished to shareholders in connection with the
solicitation of proxies by the management of TGC Industries, Inc. (the
"Company") for use at the annual meeting of shareholders to be held at Janney
Montgomery Scott Inc., 8th Floor Conference Room, 26 Broadway, New York, New
York on June 5, 1997 and at any adjournment thereof.  The Notice of Meeting,
the form of Proxy, and this Proxy Statement are being mailed to the Company's
shareholders on or about April 21, 1997.


                  COSTS OF PROXY SOLICITATION

     Although solicitation (the total expense of which will be borne by the
Company) is to be made primarily through the mail, the Company's officers
and/or employees and those of its transfer agent may solicit proxies by
telephone, telegram, or personal contact, but in such event no additional
compensation will be paid by the Company for such solicitation.  Further,
brokerage firms, fiduciaries, and others may be requested to forward
solicitation material regarding the meeting to beneficial owners of the
Company's Common Stock, and in such event the Company will reimburse them for
all accountable costs so incurred.


                         ACTION TO BE TAKEN

     Action will be taken at the meeting to (1) elect a Board of Directors,
(2) ratify selection of Grant Thornton LLP as independent auditors, and (3)
transact such other business as may properly come before the meeting and any
adjournment thereof.  The proxy will be voted in accordance with the
directions specified thereon, and otherwise in accordance with the judgment
of the persons designated as proxies.  Any person executing the enclosed
proxy may nevertheless revoke it at any time prior to the actual voting
thereof by filing with the Secretary of the Company either a written
instrument expressly revoking it or a duly executed proxy bearing a later
date.  Furthermore, such person may nevertheless elect to attend the meeting
and vote in person, in which event the proxy will be suspended. 


                        OUTSTANDING STOCK

     The Company's Restated Articles of Incorporation authorize 25,000,000
shares of Common Stock with a par value of $.10 per share and 4,000,000
shares of Preferred Stock with a par value of $1.00 per share.  As of April
18, 1997 (the "Record Date"), which is the date as of which the record of
shareholders entitled to vote at the meeting was determined, there were
6,315,738 shares of the Company's Common Stock outstanding and 1,148,850
shares of the Company's Preferred Stock outstanding.

     In voting on all matters expected to come before the meeting, a
shareholder will be entitled to one vote, in person or by proxy, for each
share of Common Stock and Preferred Stock held in his name on the Record
Date.  The Company's Restated Articles of Incorporation prohibit cumulative
voting.


                      SECURITY OWNERSHIP OF CERTAIN
                      BENEFICIAL OWNERS AND MANAGEMENT

The following tabulation sets forth the names of those persons who are known
to Management to be the beneficial owner(s) as of March 20, 1997 of more than
five percent (5%) of the Company's Common Stock or Preferred Stock.  Such
tabulation also sets forth the number of shares of the Company's Common Stock
or Preferred Stock beneficially owned as of March 20, 1997 by all of the
Company's directors and nominees (naming them), executive officers, and all
directors and officers of the Company as a group (without naming them). 
Persons having direct beneficial ownership of the Company's Common Stock or
Preferred Stock possess the sole voting and dispositive power in regard to
such stock.  The Preferred Stock is freely convertible into shares of Common
Stock at the conversion price per share of Common Stock of $0.75 if converted
prior to close of business on July 1, 1998, at the conversion price per share
of Common Stock of $1.25 if converted after July 1, 1998 but prior to close
of business on July 1, 1999, and at the conversion price per share of Common
Stock of $2.00 thereafter.  Ownership of Preferred Stock is deemed to be
beneficial ownership of Common Stock at the conversion price per share of
$0.75 under Rule 13d-3(d) (1) promulgated under the Securities Exchange Act
of 1934.  As of March 20, 1997, there were 6,315,738 shares of Common Stock
and 1,148,850 shares of Preferred Stock outstanding.

*Denotes less than 1% beneficial ownership. (1) The percentage calculations have been made in accordance with Rule 13d-3(d)(1) promulgated under the Securities Exchange Act of 1934. In making these calculations, shares of Common Stock beneficially owned by a person as a result of the ownership of Preferred Stock and certain options and warrants were deemed to be currently outstanding solely with respect to the holders of such Preferred Stock, options, and warrants. (2) Includes the number of shares of Common Stock which are deemed to be beneficially owned as a result of ownership of shares of Preferred Stock, which Preferred Shares ($5.00 per share) are freely convertible into shares of Common Stock at the conversion price per shares of Common Stock of $.75 through July 1, 1998. (3) Includes the number of Shares of Common Stock set forth opposite the person's name in the following table, which shares are beneficially owned as a result of the ownership of Stock Options and Stock Purchase Warrants.

Mr. Campbell has disclaimed beneficial ownership of these shares. (5) Excludes 83,848 shares of Common Stock owned by Herbert M.

Mr. Barrett has disclaimed beneficial ownership of these shares. Depositories such as The Depository Trust Company (Cede & Company) as of March 20, 1997 held, in the aggregate, more than five percent (5%) of the Company's then outstanding Common Stock voting shares. The Company understands that such depositories hold such shares for the benefit of various participating brokers, banks, and other institutions which are entitled to vote such shares according to the instructions of the beneficial owners thereof. The Company has no reason to believe that any of such beneficial owners hold more than five percent (5%) of the Company's outstanding voting securities. MANAGEMENT AND NOMINEES FOR DIRECTOR Five (5) directors, comprising the entire membership of the Company's Board of Directors, are to be elected at the annual meeting of shareholders. Unless otherwise instructed, the proxy holders will vote the proxies received by them for the nominees shown below for a term of one year and until their successors are duly elected and have qualified. Although it is not contemplated that any nominee will be unable to serve as a director, in such event the proxies will be voted by the holders thereof for such other person as may be designated by the current Board of Directors. The Management of the Company has no reason to believe that any of the nominees will be unable or unwilling to serve if elected to office, and to the knowledge of Management, the nominees intend to serve the entire term for which election is sought. There are no family relationships by blood, marriage, or adoption between any director or executive officer, or person nominated or chosen to become a director or executive officer. Only five (5) nominees for director are named, even though the Company's bylaws allow a maximum of nine, since the proposed size of the board is deemed adequate to meet the requirements of the Board of Directors. Up to two vacancies may be filled by the Board of Directors under Texas law during the time between any two successive annual shareholder meetings if suitable persons are designated. The information set forth below with respect to each of the nominees has been furnished by each respective nominee.

The Company's Board of Directors recommends that you vote FOR the nominees named above for election to the Board of Directors. COMMITTEES AND MEETINGS OF THE BOARD OF DIRECTORS The Board of Directors has an Executive Committee comprised of Messrs. McInnes, Gardner, Barrett and Campbell. The Executive Committee, which met two times during the fiscal year ended December 31, 1996, is charged by the Company's bylaws with the responsibility of exercising such authority of the Board of Directors as is specifically delegated to it by the Board, subject to the limitations contained in the bylaws. The Executive Committee is also responsible for reviewing the compensation of the independent auditors; conferring with the outside auditors to assure that personnel in the treasurer's and controller's departments are adequately trained and supervised; meeting periodically with the independent auditors, Board of Directors, and certain officers of the Company to insure the adequacy of internal controls and reporting; reviewing the financial statements and conducting pre-audit and post-audit review to assure the adequacy of all phases of the audit; and performing any other duties or functions deemed appropriate by the Board. No compensation is paid to members of the Board of Directors, other than the reimbursement of out-of-pocket expenses for travel to meetings of the Board of Directors. The Board of Directors does not have audit, nominating, or compensation committees. The functions of a compensation committee are performed by the entire Board of Directors. During the fiscal year ended December 31, 1996, the Board of Directors held ten (10) special meetings in addition to its regular meeting. EXECUTIVE COMPENSATION The table below sets forth on an accrual basis all cash and cash equivalent remuneration paid by the Company during the year ended December 31, 1996 to the Chief Executive Officer and any other executives whose salary and bonus exceeded $100,000, if any.

(4) A 1994 bonus of $18,500 paid in 1995. (5) A 1993 bonus of $15,000 paid in 1994. (6) Mr. McInnes resigned as Chief Executive Officer of the Company in March, 1996. Prior to that time, Mr. McInnes was President and Chief Executive Officer of TGC Industries, Inc. Represents personal use of Company vehicle ($5,260), life insurance premiums ($900), and Company's contribution to 401-K program ($3,484). (7) Represents personal use of Company vehicle ($575), life insurance premiums ($900) and Company's contribution to 401-K program ($4,019). The Company maintains Club memberships for certain of its executive officers. Although these memberships may be utilized from time-to-time for non-business purposes, the costs attributable to non-business purposes were not material. The Company believes that the aggregate amounts of such personal benefits do not exceed 10% of cash compensation paid to any individual in the table or, with respect to the group of all executive officers, ten percent (10%) of the aggregate cash compensation paid to the members of such group. (401(k) PLAN In 1987, the Company implemented a 401(k) salary deferral plan (the Plan) which covers all employees who have reached the age of 20-1/2 years and have been employed by the Company for at least one year. The covered employees may elect to have an amount deducted from their wages for investment in a retirement plan. The Company has the option, at its discretion, to make contributions to the Plan. Effective January 1, 1990, the Company determined in its discretion to make a matching contribution to the Plan equal to 10% of the employees' contributions up to 6% of those employees' compensation. On July 24, 1991, to be effective August 5, 1991, the Board of Directors increased the Company's matching contribution to the Plan to fifty cents ($.50) for every one dollar ($1.00) of compensation a participant defers under the Plan up to 6% of those employees' compensation. Beginning January 4, 1993, the Board of Directors discontinued the matching contribution to the Plan. Concurrently with the acquisition of Chase Packaging, the Board of Directors reinstated contributions to the 401(k) salary deferral plan. The Company makes a matching contribution to the Plan equal to the sum of seventy-five percent (75%) of each Participant's salary reduction contributions to the Plan for such Plan year which are not in excess of three percent (3%) of the Participant's compensation for such Plan year, and fifty percent (50%) of each Participant's salary reduction contributions to the Plan for such Plan year which are in excess of three (3%) of the Participant's compensation but not in excess of eight percent (8%) of the Participant's compensation for such Plan year. The total amount of the Company's contribution during 1996 for the two (2) executive officers of the Company participating in the 401(k) Plan was as follows: Robert J. Campbell - $3,148.65 and Wayne A. Whitener - $2,945.78. STOCK OPTION PLANS 1986 Incentive and Nonqualified Stock Option Plan In 1986 the Company adopted the 1986 Incentive and Non-Qualified Stock Option Plan (the "1986 Plan"). The term of the 1986 Plan was for a period of ten years with the result that the 1986 Plan terminated on July 24, 1996. The provisions which were contained in the 1986 Plan were comparable to the provisions contained in the 1993 Plan (hereafter described) which succeeded the 1986 Plan. Options granted under the 1986 Plan cover 44,668 shares which are currently outstanding. During 1996, 25,000 stock options were granted under the 1986 Plan. Any stock option outstanding as of the date of termination of the 1986 Plan will remain outstanding until it is exercised, terminated, or expires. 1993 Stock Option Plan On June 3, 1993, the Company's Board of Directors approved and adopted the Company's 1993 Stock Option Plan (the "1993 Plan"). At the 1994 Annual Meeting, shareholders approved the 1993 Stock Option Plan. The following paragraphs summarize certain provisions of the 1993 Stock Option Plan and are qualified in their entirety by reference thereto. The 1993 Plan provides for the granting of options (collectively, the "Options") to purchase shares of the Company's Common Stock to certain key employees of the Company (and/or any of its affiliates), and certain individuals who are not employees of the Company but who from time-to-time provide substantial advice or other assistance or services to the Company (and/or any of its affiliates). The 1993 Stock Option Plan authorizes the granting of options (both statutory and non-statutory) to acquire up to 750,000 shares of Common Stock, subject to certain adjustments described below, to be outstanding at any time. Subject to the foregoing, there is no limit on the absolute number of awards that may be granted during the life of the 1993 Stock Option Plan. At that time, there are approximately 350 employees of the Company, including four officers of the Company (three of whom are also directors), who, in management's opinion, would be considered eligible to receive grants under the 1993 Plan, although fewer employees may actually receive grants. Authority to administer the 1993 Plan has been delegated to a committee (the "Committee") of the Board of Directors. Except as expressly provided by the 1993 Stock Option Plan, the Committee has the authority, in its discretion, to award Options and to determine the terms and conditions (which need not be identical) of such Options, including the person to whom, and the time or times at which, Options will be awarded, the number of Options to be awarded to each such person, the exercise price of any such Options, and the form, terms, and provisions of any agreement pursuant to which such Options are awarded. The 1993 Plan also provides that the Committee may be authorized by the Board of Directors to make cash awards as specified by the Board of Directors to the holder of an Option in connection with the exercise thereof. Subject to the limitations set forth below, the exercise price of the shares of stock covered by each 1993 Option will be determined by the Committee on the date of award. Unless a holder's option agreement provides otherwise, the following provisions will apply to exercise by the holder of his or her option: No options may be exercised during the first twelve months following grant. During the second year following the date of grant, options covering up to one-third of the shares covered thereby may be exercised, and during the third year following the date of grant, options covering up to two-thirds of such shares may be exercised. Thereafter, and until the options expire, the optionee may exercise options covering all of the shares. Persons over sixty-five on the date of grant may exercise options covering up to one-half of the shares during the first year and thereafter may exercise all optioned shares. Subject to the limitations just described, options may be exercised as to all or any part of the shares covered thereby on one or more occasions, but, as a general rule, options cannot be exercised as to less than one- hundred shares at any one time. The exercise price of the shares of stock covered by each incentive stock option ("ISO"), within the meaning of Sec. 422 of the Internal Revenue Code of 1986, as amended (the "Code"), will not be less than the fair market value of stock on the date of award of such ISO except that an ISO may not be awarded to any person who owns stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company unless the exercise price is at least one hundred ten percent (110%) of the fair market value of the stock at the time the ISO is awarded and the ISO is not exercisable after the expiration of five years from the date it is awarded. The exercise price of the shares of Common Stock covered by each Option that is not an ISO will not be less than fifty percent (50%) of the fair market value of the stock on the date of award. Payment for Common Stock issued upon the exercise of an Option may be made in cash or with the consent of the Committee, in whole shares of Common Stock owned by the holder of the Option for at least six months prior to the date of exercise or, with the consent of the Committee, partly in cash and partly in such shares of Common Stock. If payment is made, in whole or in part, with previously-owned shares of Common Stock, the Committee may issue to such holder a new Option for a number of shares equal to the number of shares delivered by such holder to pay the exercise price of the previous Option having an exercise price equal to at least one-hundred percent (100%) of the fair market value per share of the Common Stock on the date of the exercise of the previous Option. The duration of each Option will be for such period as the Committee determines at the time of award, but not for more than ten years from the date of award in the case of an ISO. In the event of any change in the number of shares of Common Stock effected without receipt of consideration therefor by the Company by reason of a stock dividend, or split, combination, exchange of shares or other recapitalization, merger, or otherwise, in which the Company is the surviving Corporation, the aggregate number and class of reserved shares, the number and class of shares subject to each outstanding Option, and the exercise price of each outstanding Option will be automatically adjusted to reflect the effect thereon of such change. Unless a holder's option agreement provides otherwise, a dissolution or liquidation of the Company, certain sales of all or substantially all of the assets of the Company, certain mergers or consolidations in which the Company is not the surviving corporation, or certain transactions in which another corporation becomes the owner of fifty percent (50%) or more of the total combined voting power of all classes of stock of the Company, will cause such holder's Options then outstanding to terminate, but such holder may, immediately prior to such transaction, exercise such options without regard to the period and installments of exerciseability applicable pursuant to such holder's option agreement. The 1993 Plan will terminate on June 3, 2003, or such earlier date as the Board of Directors may determine. Any stock option outstanding at the termination date will remain outstanding until it has been exercised, terminated, or has expired. The 1993 Plan may be terminated, modified, or amended by the Board of Directors at any time without further shareholder approval, except that shareholder approval is required for any amendment which: (a) changes the number of shares of Common Stock subject to the 1993 Stock Option Plan other than by adjustment provisions provided therein, (b) changes the designation of the class of employees eligible to receive Options, (c) decreases the price at which ISO's may be granted, (d) removes the administration of the 1993 Stock Option Plan from the Committee, or (e) without the consent of the affected holder, causes the ISO's granted under the 1993 Stock Option Plan and outstanding at such time that satisfied the requirements of Sec. 422 of the Code no longer to satisfy such requirements. During 1996 stock options of 590,000 were granted under the Company's 1993 Stock Option Plan to officers and employees of the Company, and certain officers and employees of the Company's former subsidiary, Chase Packaging Corporation. Granted options covering 535,500 shares are outstanding at December 31, 1996 under the 1993 Stock Option Plan. Effective July 31, 1996, the Company's wholly-owned subsidiary, Chase Packaging Corporation ("Chase"), was spun off to the Company's shareholders. In view of this situation, and in order to provide the employees of both Chase and the Company with the maximum period available under the tax laws for exercising their options after a termination of employment, the 1993 Plan was amended to extend from thirty days to three months, the period of time following termination of employment, during which the terminating employee can exercise his or her option. ISO's Exercised in 1996 by Officers of Company No Stock options were exercised by Officers of the Company in 1996.
