The following report is the first volume documenting the radiometric and magnetic data taken during the month of October, 1979, by EG&G geoMetrics primarily in the state of Texas in the quadrangles: Tyler, Texarkana, and Waco. This volume contains the survey description, specifications, data processing methods, interpretation methods, interpretation methods, and regional geologic review.

This report is one part of the second volume containing data on quadrangles of Texas, Oklahoma, Arkansas and Louisiana. This volume contains the detailed geologic summary, interpretation report, standard deviation maps, pseudo-contour maps, interpretation map, flight line and geologic base map, individual corrected profiles, computer map unit histograms and statistical tables for the Texarkana quadrangle.

From introduction: In this study on raw material sources of uranium the Southern Interstate Nuclear Board has catalogued all known occurrences of uranium and some references to thorium in a 17-state area (P1. 1). These occurrences have been evaluated as potential sources of uranium by the State Geological Surveys and the consultant group of SINB. Favorability guides have been applied to the known occurrences and recommendations have been made for future action by the states involved, federal agencies, or by industry. State recommendations are included in state-by-state summaries. The state reports were written either by personnel of the State Geological Surveys or were abstracted from State geological survey data by members of the consultant group...The purpose of this study was to compile information on and systematically assess uranium and other radioactive occurrences in the region. The SINB undertook the project because of its statutory, interstate capability as an extension of government in each of the 17 states, an arrangement that lends itself effectively to this cooperative undertaking.

From General Statement Purpose of the Report: "The present investigation was undertaken for the purpose of supplying some of the material so badly needed in the valuation and more efficient operation of oil properties. Because of the lack of time for further studies, the amount of data already accumulated and the policy of the Bureau of Mines of publishing as soon as possible any information that may be of use to an industry, the bulletin is issued now."

From Introduction: "Technical Paper 66 deals with the mud-laden fluid process in general and No. 68 with its application in Oklahoma. Rather than reprint these publications, it has been considered advisable to replace them with the present report, which includes the results of more recent investigations. The methods of using mud-laden fluid are an outgrowth of the rotary drilling system, which was developed in Texas and later employed in Louisiana and California."

This report presents the results of ground water, stream water, and seam sediment reconnaissance in Arkansas, Louisiana, Missippi, Missouri, Oklahoma, and Texas.
