This report provides radiometric and magnetic data for the Harrison quadrangle of southern Missouri and northern Arkansas that was acquired and processed in May of 1980. Appendix A provides a detailed summary of data acquisition, processing, interpretation, and presentation methods; Appendix B contains a flight summary report for the quadrangle.

The following report analyzes the aerial gamma ray and magnetic data taken from the Memphis quadrangle in Arkansas, Missouri, and Tennessee that was compiled in 1980. This report contains a detailed geologic summary, interpretation report, reduced scale copies of all maps and profiles, histograms, and statistical tables for the quadrangle.

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.
