Final report documenting a high-sensitivity airborne gamma radiation and magnetic field survey of the Brownsville and McAllen National Topographic Map segments including a description of the program and results.

Final report documenting a high-sensitivity airborne gamma radiation and magnetic field survey of the Houston National Topographic Map segment (NH 15-7 quadrangle) including a description of the program and results.

"The results of analyses of the airborne gamma radiation and total magnetic field survey flown for the region identified as the Socorro National Topographic Map NI13-4 is presented in this report"--Abstract.

"Results of a reconnaissance geochemical survey of the Scottsbluff Quadrangle are reported. Field and laboratory data are presented for 567 groundwater and 402 stream sediment samples. statistical distributions and symbol plots for uranium and possible uranium-related variables are enclosed. A generalized geologic map and a producing horizon map for the survey area are provided. Pertinent geologic factors that may be of significance in evaluating the potential for uranium mineralization are briefly discussed."
