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.
