Reporting investigations into the lithologic and structural ore controls as revealed by this exploration program.

From abstract: Results of a reconnaissance geochemical survey of the Emory Peak Quadrangle, Texas are reported. Field and laboratory data are presented for 193 groundwater samples and 491 stream sediment samples. Statistical and areal distributions of uranium and other possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.

Data collected as part of a hydrogeochemical and stream sediment reconnaissance for Emory Peak NTMS quadrangle in Texas including laboratory data on well water (pp. 1-5) and stream sediments (6-15) as well as field data (pp. 16-171).

Data collected as part of a hydrogeochemical and stream sediment reconnaissance for Presidio NTMS quadrangle in Texas including laboratory data on well water (pp. 1-3) and stream sediments (pp. 4-5) as well as field data (pp. 6-47).

From abstract: Results of a reconnaissance geochemical survey of the Presidio Quadrangle, Texas are reported. Field and laboratory data are presented for 79 groundwater samples and 105 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.

From abstract: Results of a reconnaissance geochemical survey at a nominal sample spacing of 16 km (10 mi) are reported for the Plainview, Lubbock, and Big Spring Quadrangles in northwest Texas. Stream sediment, stream water, and groundwater were analyzed for approximately 25 parameters.
