The information contained in this circular was gathered by a unit of the WPA Mineral Resources Survey of Texas, a project sponsored by The University of Texas, Bureau of Economic Geology. The purpose of this survey is to assemble information concerning mineral products and to gather other geologic data and make it available to the public. With this information in the hands of the public, it is reasonable to suppose that industries of value to the State may be developed. The following report is based on work done in Collingsworth County by Work Project No.

As an outcome of a paper published by The University of Texas in 1938 calling attention to the high magnesia marbles of the Sharp Mountain area of Llano County, magnesite is mined at the present by two companies, the Meramec Minerals, Inc., and the Texas Mines. The Sharp Mountain area is a part of the metamorphic series, probably Algonkian in age, composed mainly of mica and graphitic schists, diorites, granite, dolomite, magnesite, magnesitic limestone, and calcium carbonate marble.

A mineral resource survey of Texas, started by the Works Progress Administration, is still being conducted by the Works Projects Administration, with the Bureau of Economic Geology of The University of Texas acting as the sponsor. The purpose of the survey is to assemble information and make it available to the public. The mineral resource survey is helping in the location of mineral products, from some of which it is reasonable to suppose industries of value to the state may be developed. The following report is based on work done in Wichita County by Work Project No.
