From purpose and scope: The Lawton Quadrangle, Oklahoma and Texas (Fig. 1), was evaluated to a depth of 1500 m (5,000 ft) to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits. Determination of uranium favorability was based on the similarity of geologic characteristics to the National Uranium Resource Evaluation (NURE) recognition criteria described in Mickle and Mathews (eds., 1978).

Appendices containing data on uranium availability in the Lawton Quadrangle to accompany a report on U.S. uranium resources in Oklahoma and Texas.

Discussing the evaluation made of the Plainview NTMS Quadrangle to identify and delineate areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits.

From purpose and scope: The Amarillo, Texas, Quadrangle of the National Topographic Map Series (NTMS), scale 1:125,000, was evaluated to identify and delineate geologic environments favorable for the occurrence of uranium. The study was conducted by the Bureau of Economic Geology (BEG) of the University of Texas at Austin, under subcontract to Bendix Field Engineering Corporation (BFEC), for the National Uranium Resource Evaluation (NURE) program, managed by the Grand Junction Office of the U.S. Department of Energy (DOE). The evaluation began March 31, 1978, and ended March 31, 1980. Time spent by the authors and other BEG personnel in literature search, field work, evaluation of data, and preparation of the final report totaled approximately six man-years.

Appendices containing supplementary chemical analysis to accompany a report on U.S. uranium resources in the Amarillo Quadrangle, Texas.

Final report documenting the statistical analysis of an aerial gamma-ray and magnetic survey of the Red River Area including the Ardmore, Sherman, Abilene, and Dallas quadrangles in north Texas and southern Oklahoma. Quadrangle-specific maps and data are published as separate volumes.
