Geology and Uranium Deposits of Part of the Browns Park Formation, Colorado, Wyoming, and Utah: a Preliminary Report

Description: From abstract: Uranium deposits and radioactivity anomalies have been found in the eastern half of the area underlain by the Browns Park formation in northwestern Colorado, south-central Wyoming, and northeastern Utah. The deposits are in eolian, lacustrine, and fluvial sandstones, tuffaceous sandstones, and limestones all of which were deposited on two converging pediments during Miocene time. At least one eastern and one western facies of lacustrine and fluvial sedimentary rocks are separated… more

Identification and Occurrence of Uranium and Vanadium Minerals From the Colorado Plateaus

Description: 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."

Preliminary Study of Radioactive Limonite Localities in Colorado, Utah, and Wyoming

Description: Report discussing a preliminary study of limonite sourced from nine localities of different types through Colorado, Utah and Wyoming, in the spring and fall of 1953. This study aimed to establish criteria for differentiating uranium- and thorium-related limonite and limonite not related to uranium or thorium. The report is divided by descriptions of each locality.

Reconnaissance During 1952 for Uranium-Bearing Carbonaceous Rocks in Parts of Colorado, Utah, Idaho, and Wyoming

Description: The following report covers a reconnaissance for uranium-bearing carbonaceous rocks that was made during the 1952 field season in 23 areas in Colorado, Utah, Idaho, and Wyoming. This report discusses uranium samples discovered withing these locations, however it was determined that none of the deposits discovered have commercial possibilities.

Reconnaissance During 1952 for Uranium-Bearing Carbonaceous Rocks in Parts of Colorado, Utah, Idaho, and Wyoming

Description: Report discussing a reconnaissance for uranium-bearing carbonaceous rocks during the 1952 field season in 23 areas in Colorado, Utah, Idaho, and Wyoming. From Abstract: "Uranium in small amounts occurs in several of the areas examined, but no deposits were found that might have commercial possibilities."

Reconnaissance for Uraniferous Rocks in Northwestern Colorado, Southwestern Wyoming, and Northeastern Utah

Description: The following report covers a reconnaissance for new discoveries of radioactive lignite deposits in the Green River Basin and Uinta Basin of Wyoming and Utah where similar discoveries to previous studies in North Dakota, South Dakota, Montana, and Wyoming were made. Additionally, there were new prospects examined, as well as reconnaissance for uranium deposits.

Reconnaissance for Uranium-Bearing Carbonaceous Rocks in Northwestern Colorado, Southwestern Wyoming, and Adjacent Parts of Utah and Idaho

Description: Abstract: During parts of July, August, and September 1951, a reconnaissance was conducted in parts of Colorado, Wyoming, Utah, and Idaho in search of new deposits of uranium-bearing carbonaceous rocks. One significant uranium occurrence was found, the Fall Creek deposit, Bonneville County, Idaho. Several additional localities were discovered that contain uranium in concentrations many times that normally found in carbonaceous rocks.

Reconnaissance of Some Geologic Formations in Southeastern Idaho, Western Wyoming, and Northern Utah

Description: Abstract: A radiometric reconnaissance, using a portable beta-gamma survey meter, of some geologic formations ranging in age from Cambrian to Cretaceous, and springs in southeastern Idaho, western Wyoming, and northern Utah, has shown that none of them are sufficiently radioactive to warrant further examination of them in the area.
