Report discussing a study of the mineralogy of various Jurassic and Cretaceous claystones and siltstones of Colorado and Utah. The study was aimed at determining which minerals characterize fine sediments which include important uraniferous strata.

Report summarizing information regarding the mineralogy of uranium ores of the Colorado Plateau. The report includes sections on classification, mineralogy of the primary unoxidized ores, oxidation sequence and mineralogy of vanadiferous uranium ores, mineralogy of oxidized nonvanadiferous uranium ores, relation of oxidation to water saturation of ore, relative stability and size of oxidized deposits, secondary enrichment, and time and depth of oxidation.

The following report covers investigation work done on the distribution of thick deposits of salt that had occurred in the Paradox member of the Hermosa formation of Pennsylvanian age in an area nearly 12,000 square miles of southwestern Colorado and southeastern Utah.

From scope of report: "The fluorite district in the western part of the Thomas Range, Juab County, Utah, is one f the newest mining districts in western United States; since 1950 it has been the largest producer of fluorite west of the Mississippi River. The present report covers the geology of the entire fluorite producing area, and supplements an earlier report...on the individual mining properties."

Report discussing the investigation of rabbittite, a hydrated calcium magnesium uranyl carbonate found in a mine of the San Rafael district of Emery County, Utah, in July, 1952. Information regarding rabbittite's occurrence, physical/optical properties, chemical composition, and X-ray diffraction data are included.

This report describes the distribution of geologic features that may be used as geologic guides to carnotite deposits, sedimentary trends of the ore-bearing sandstone, and regional structures within and adjacent to the Urvan mineral belt in the Urvan and Gateway mining districts, Montrose and Mesa Counties, Colorado.

A report regarding the geology of the Thomas Range Fluorite District, in Juab County, Utah. This report concerns work done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

A report regarding the distribution and thickness of salt in the paradox basin of southeastern colorado and southeastern Utah. This report concerns work done on behalf of the Division of research of the U.S. Atomic Energy Commission.

"This report briefly describes the [Urvanian Mineral Belt] and outlines the geologic evidence supporting its concept. General plans for continuous exploration of this belt, and preliminary prediction of the total amount of carnotite-bearing rocks that might be in one unexplored area, are also presented"
