Carnotite Resources of the Legin Group Area, San Miguel County, Colorado

Description: From abstract: The Legin group area comprises five privately owned claims, nine Government claims, and some public land. The area is in parts of secs. 28 and 29, T. 43 N., R. 19 W., New Mexico principal meridian, San Miguel County, Colo. It is about 45 miles from the Government mill at Monticello, Utah, and 50 miles from the Vanadium Corporation of America mill at Naturita, Colo. The Legin group area has yielded a total production of more than 18,000 short tons of carnotite ore that averaged 0.… more

The Colorimetric Determination of Total Iron With O-Phenanthroline

Description: From Abstract: "A study of the critical factors in the colorimetric determination of total iron in silicate and phosphate rocks, and in other nonmetallic materials is presented. It was desired to ascertain the wavelength of maximum absorbancy, the optimum concentration range for iron, the effect of different substances on the ferrous-o-phenanthroline system, and reproducibility of results."

Compilation of Data on the Uranium and Equivalent Uranium Content of Samples Analyzed by U.S. Geological Survey During a Program of Sampling Mine, Mill, and Smelter Products

Description: Report discussing the sources of about 1,400 samples of samples of mine, mill, and smelter products that were collected by the U.S. Geological Survey. In addition, the "kind of material sampled, i.e. ores, concentrates, middlings, tailings, flue dusts, and so forth, and the radioactivity of the samples are listed in the report."

Distribution and Origin of Phosphate in the Land-Pebble Phosphate District of Florida

Description: From abstract: The land-pebble phosphate district of Florida is a part of the Gulf Coastal Plain. The geologic formations cropping out in the district are the Miocene Hawthorn, Pliocene Bone Valley, and Pleistocene terrace sands. The Bone Valley formation consists of a lower strongly phosphatic unit and an upper less phosphatic unit. This paper is concerned principally with the lower unit, which contains the bulk of the minable phosphate deposits of the district.

Domestic Phosphate Deposits

Description: From abstract: Incomplete but recently partly revised estimates indicate the presence of about 10 billion tons of phosphate deposits in the Urited States that is minable under present economic conditions. Deposits too lean in quality or thickness to compete with those in the western and southeastern fields probably contain tens of billions of tons.

The Effect of Ashing Temperatures on the Volatility of Germanium in Lignite Samples

Description: Abstract: A study has been conducted to provide data on the loss of germanium from ashed lignite samples. The lignite samples, of known germanium content, were ashed at various temperatures as high as 1000 °C with varying rates of heating and varying amounts of surface area of the lignites. The results indicate that no germanium was volatilized during the various ignitions.

Geological Survey's Work on Isotope Geology of Uranium, Thorium, and Their Decay Products

Description: Report discussing a research program on the isotope geology of the uranium and thorium series. From Abstract: "Work is in progress on uranium-lead relationships in uranium ores of the Colorado Plateau region; on uranium-thorium-lead relationships in granite; on geologic variations in the isotopic composition of lead; and on radon and helium in natural gas."

The Geological Survey's Work on the Geology of Uranium and Thorium Deposits

Description: From abstract: The Geological Survey has been studying the geology of uranium and thorium continuously since 1939, when it began a comprehensive investigation of the vanadium-uranium deposits of the Colorado Plateau. Greatly increased demand for uranium arising from the advent of controlled fission in 1942 resulted in widening of the study in 1944 to include other possible sources and in further expansion on behalf of the U. S. Atomic Energy Commission since 1947. The wide variety of materials… more

Geology of the Quartz Creek Pegmatite District, Gunnison County, Colorado

Description: Report discussing the geology of the Quartz Creek pegmatite district of Gunnison County, Colorado. "The Quartz Creek pegmatite district includes an area of about 29 square miles in the vicinity of Quartz Creek in Gunnison County, Colorado. This area contains 1,803 pegmatites that are intruded into pre-Cambrian rocks."
