[en] New geologic and uranium occurrence maps have been prepared for Arminto, Thermopolis, and Lander NTMS quadrangles, Wyoming, to match the revised maps of the Casper Quadrangle. The 1974 survey data for all four quadrangles were reprocessed using an improved U-air correction, a statistical adequacy test, and a low-pass filter to improve data quality. The radiometric data were then line-tied with correction of mismatches to minimize the effects of uncompensated U-air and moisture absorption of the gamma radiation on certain E--W lines. The improved and tied data were then processed to produce conventional radiometric anomaly maps, significance-level profile mpas, significance-level stacked profiles, and, on the Casper Quadrangle only, numerical significance-factor maps. The data displays were interpreted comparatively to determine which display was easiest to use and most effective in delineating uraniferous provinces and prospects and to evaluate the effects of line-tying on data affected by uncompensated U-air and surface moisture. It was concluded that the convolution-type low-pass filter designed for elementary rod-source signals in this data set was vastly superior to unweighted, multipoint running averaging in removing noise and preserving signal. Line-typing was effective in partially eliminating the effects of uncompensated U-air and surface moisture variations. A computerized method of picking statistically significant eU, eU/eTh, and eU/K anomalies proved much faster, much less costly, and more accurate than manual picking using any of the displays. The significance-factor profile maps are distinctly better formats for interpretation than the conventional or numerical anomaly maps in that they provide a quick graphical display of the extent and magnitude of high and low regions and allow a much more quantitative estimate of the statistical validity of anomalous areas
