From Introduction: "The Front Range region from the Wyoming-Colorado state line to southern Colorado is a uranium metallogenic province. Correspondingly, uranium has been discovered in mineable deposits in metamorphic, igneous, and sedimentary rocks formed throughout the geologic history of the region both within the Front Range itself and in the apron of sedimentary rocks that surrounds the Front Range. The Pueblo 1ºx2º National Topographic Map Series (NTMS) quadrangle, Colorado (Fig. 1), which lies within this uranium metallogenic providence, was evaluated to identify and delineate areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits."

Report discussing investigations seeking uranium in deposits of black shale around the geographical areas of the Western States

From introduction: The purpose of the investigation was to attempt to correlate anomalous radioactivity and mineral distribution in a metal-mining district that shows a distinct areal pattern of distribution of vein types,

"This report consists of engineering details, statistics, and logistics of the 19 boreholes drilled in the project. Geophysical logs are included on microfiche in the back of this report." (from Introduction)
