Carnotite Resources of the Legin Group Area, San Miguel County, Colorado
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 0.32 percent U30 and 2.5 percent V 205 . Most of this production was accomplished during the years from 1935 to 1944, and from 1949 to October 1951.

The Occurrence of Zeunerite at Brooks Mountains, Seward Peninsula, Alaska
Abstract: Zeunerite occurs near the surface of a granite stock on the southwest flank of Brooks Mountain, Alaska. The largest deposit is at the Foggy Day prospect where zeunerite is disseminated in hematite which partially or totally fills openings and vugs in a highly oxidized lensshaped body of pegmatitic granite and to a minor extent in openings and cracks in the weathered granite enclosing the lens. Although a few specimens from the pegmatitic lens contain as high as 2.1 percent equivalent uranium, the overall average content of the lens rock is between 0.1 and 0.2 percent equivalent uranium and about 0.07 percent equivalent uranium for both the lens material and the surrounding zeunerite-bearing granite.

Uranium Content of Chattanooga Shale in East-Central Tennessee and Southern Kentucky
From abstract: Uranium assays of all the samples collected by the Geological Survey from the Chattanooga shale in east-central Tennessee and southern Kentucky from 1947 to 1949 are assembled here, and conclusions are drawn concerning the distribution of the uranium. The 1108 assays from 80 localities provide reasonably reliable information on the stratigraphic and regional variations of the uranium content.

Geology and Uranium Occurrences in the Miller Hill Area, Carbon County, Wyoming
Abstract: Uranium occurs in the North Park(?) formation of Pliocene(?) age in the Miller Hill area, about 25 miles south of Rawlins, Carbon County, Wyo. As much as 0. 5 percent uranium is contained in grab samples, but only about 1000 tons of rock are known to contain as much as 0. 03 percent uranium. Beds of brecciated, silicified limestone 3 to 10 feet thick contain the principal concentrations of uranium. Lesser concentrations are found in calcareous sandstone and quartzite. Uranophane, Ca(UOz)2SizO 7 . 6HZO, the principal uranium'mineral, has been deposited in vugs, as fracture and surface coatings, and as a disseminated constituent of the rock. Uranium also occurs in quantities too small to be megascopically visible in dark-colored chalcedony, lime stone, sandstone, and quartzite beds.

Uranium-Bearing Nickel-Cobalt-Native Silver Deposits, Black Hawk District, Grant County, New Mexico
From introduction: Mining began in the Black Hawk (Bullard Peak) district in 1881 when high-grade silver ore was found at the Alhambra mine. Most of the silver produced was native silver, associated with nickel and cobalt arsenides and sulfides. In 1920 pitchblende was recognized on the dumps of some of the old mines, and since 1949 the district has been of interest as a possible source of ores that contain uranium, nickel, and cobalt.

Uranium Occurrences on the Merry Widow Claim, White Signal District, Grant County, New Mexico
From abstract: The Merry Widow claim is near the center of sec. 22, T. 20 S., R, 15 W, New Mexico principal meridian, about 1 mile west of White Signal, Grant County, N. Mex. Secondary uranium minerals were discovered in the White Signal district in the early 1920's although several mines in the district had been worked previously for gold, silver, and copper. The writers mapped the Merry Widow claim in 1950, collected 133 samples, and logged the core from one diamond-drill hole on the Merry Widow claim.

Geologic Summary of the San Juan Basin, New Mexico, with Reference to Disposal of Liquid Radioactive Waste
From introduction: Approximately fifty radioactive deposits and nearly fifty properties not abnormally radioactive were examined during a geologic reconnaissance for radioactive minerals in Idaho, Washington, and western Montana during the period July 1952 -- June 1955. The most important uranium deposits are in or near granitic to quartz monzonitic intrusions of probable Cretaceous age in central and northern Idaho, westernmost Montana, and northeastern Washington. The purpose of these reports is to describe the geology of the areas so that the possibilities for the disposal of high-level radioactive fluid waste in deep wells can be ascertained.

The Permian Phosphate Deposits of Western United States
From abstract: The Permian marine phosphorite deposits of the western United States were laid down in the Phosphoria formation and its partial stratigraphic equivalents over an area of about 135,000 square miles in Montana, Idaho, Wyoming, Utah, and Nevada. The deposits in the eastern part of the field lie on the western margin of the structurally simple North American craton.

Domestic Phosphate Deposits
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.

Uranium-Bearing Copper Deposits in the Coyote District, Mora County, New Mexico
Abstract: Uranium-bearing copper deposits occur in steeply dipping beds of the Sangre de Cristo formation of Pennsylvanian and Permian age south of Coyote, Mora County, N. Mex. Mapping and sampling of these deposits indicate that they occur in lenticular carbonaceous zones in shales and arkosic sandstones. Samples from these zones contain as much as 0.067 percent uranium and average 3 percent copper. Metatyuyamunite is disseminated in some of the arkosic sandstone beds, and uraninite was identified in some of the copper sulfide nodules occurring in the shale. In polished section these sulfide nodules were found to be composed principally of chalcocite with some bornite and covellite, as well as pyrite and malachite. Most of the samples were collected near the surface from the weathered zone. The copper and uranium were probably deposited with the sediments and concentrated into zones during compaction and lithification. Carbonaceous material in the Sangre de Cristo formation provided the environment that precipitated uranium and copper from mineral-charged connate waters forced from the clayey sediments.

Radioactivity in Some Oil Fields of Southeastern Kansas
From abstract: Radium-bearing precipitates derived from 'oil-well fluids have been found in more than 60 oil and gas fields in Cowley, Butler, Marion, Sedgwick, and Greenwood Counties of southeastern Kansas. The abnormal radioactivity of these precipitates has been studied through the use of gamma-ray and sample logs; by radiometric, chemical petrographic, and spectrographic analyses of the precipitates and drill samples; and through the use of chemical analyses of brines collected from oil wells in the areas of high radioactivity.
