摘要

During the months of August through September, 1978, geoMetrics, Inc. flew approximately 9000 line miles of high sensitivity airborne radiometric and magnetic data In eastern Wyoming and southern Montana over three 1° x 2° NTMS quadrangle (Newcastle, Gillette and Ekalaka) as part of the Department of Energy's National Uranium Resource Evaluation program.nAll radiometric and magnetic data were fully reduced and interpreted by geoMetrics, and are presented as four volumes (one Volume I and three Volume II's) in this report.nThe survey area lies entirely within the northern Great Pla ns Physiographic Province. The deep Powder River Basin and the Black Hills Uplift are the two dominant structures in the area. Both structures strike NNW approximately parallel to each other with the Powder River Basin to the west of the Uplift.
