From introduction: Geodata International, Incorporated, conducted an airborne gamma ray and total magnetic field survey which covered a region of North Texas, New Mexico and Oklahoma. The specific area of this report as outlined on Figure 1 was surveyed from an aircraft using large-volume radiation detectors with computer controlled airborne equipment. Each map line was flown in an east-west direction with an average length of 120 miles and each tie line was flown in a north-south direction with an average length of 69 miles. Map lines and tie lines were surveyed spaced at intervals indicated on Figure 2. The data for the total area of Figure 1 were gathered between March-July, 1976.
