Abstract: "This report, designed to make available to field geologists and others information on identification and occurrence of uranium minerals of the Colorado Plateaus, contains physical properties, X-ray data, and in some instances results of chemical and spectrographic analysis of 24 uranium and 17 vanadium minerals. Also included is a table giving the optical properties of uranium minerals and a list of locations of mines from which the minerals have been identified."

The following report is the first in a series of volumes presenting data recorded during the months of August and September, 1978, from a radiometric and magnetic survey taken in four quadrangles between eastern Wyoming, North and South Dakota, and southern Montana (Newcastle, Gillette and Ekalaka).

This report presents the results of an airborne radiometric survey that was made of the Inyan Kara group in the Black Hills of South Dakota and Wyoming between March 5 to December 5, 1952.
