"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"

Report issued by the U.S. Bureau of Mines on the oil-shale reserves near the Green River formation. Samples are analyzed for economic value, and presented in tables and illustrations. The report also includes maps of the sample areas.

From introduction: This preliminary report summarizes the results of the 1950 drilling in the Legin group area of San Miguel County, Colorado and gives a more complete, but preliminary, estimate of the uranium and vanadium ore reserves. When the radiometric and chemical assay data are completed, a detailed report will be transmitted.

From abstract and summary: The Blue and Moon Mesa areas are about 13 miles southeast of Gateway, Mesa County, Colo. Total production of carnotite ore from the Blue and Moon Mesa areas has been about 1,000 short tons that averaged about 0.25 percent U30Oand 1.75 percent V205. Most of this production was obtained from 1940 to 1943 and in 1949. The U. S. Geological Survey explored the northern parts of these areas by diamond drilling between August 9 and December 14, 1950. The Survey drilled 113 holes, totalling 16,039 feet. This drilling was mostly wide-spaced and was done to obtain geologic information.

Map to accompany report showing the preliminary reserve statement on the drilling of ore deposits in Atkinson Mesa, Colorado.

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 discussing a series of geological investigations of the Wet Mountains in Custer County, Colorado, including reconnaissance for thorium and detailed topographical mapping of the area. The investigations took place from 1950-1952.

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.

"Thorium deposits were discovered in the Powderhorn district in 1949. This district has long been known for its occurrences of alkalic igneous rocks, of which the best known is the Iron Hill complex (Larsen, 1942). Some of these alkalic rocks contain titanium, barium, strontium, rare earths, thorium, and niobium in greater percentages than those of most igneous rocks. A study of the thorium deposits was undertaken to obtain more information on the geologic relation of minor elements, particularly rare earths, and thorium, to alkalic igneous rocks, and to evaluate the economic significance of the Thorium deposits."
