From September 15 to 28, 1978, geoMetrics, Inc., collected 4320 line miles of high sensitivity airborne radiometric and magnetic data in Wyoming and Nebraska within two 1/sup 0/ x 2/sup 0/ NTMS quadrangles (Torrington and Casper). All radiometric and magnetic data were fully reduced and interpreted by geoMetrics, and are presented as 3 volumes (one Volume I and two Volume II's) in this report. These two quadrangles lie primarily within the Wyoming Basins Physiographic Province. The basin-uplift structure is the dominant geologic trend of the survey area. Major faulting occurs on the boundaries of the uplifts. The majority of exposed rocks are nonmarine sediments of Cenozoic and Mesozoic age. Major uranium ore deposits occur in Tertiary rocks within the Gas Hills, Crooks Gap, and Shirley Basin Districts. Scattered minor occurrences of uranium are found in Phanerozoic and Precambrian rocks throughout the area.
