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.

Trace Elements Reconnaissance on the South Fork of Quartz Creek, Northeastern Seward Peninsula, Alaska
Abstract: Two uranium-bearing minerals, uranothorianite and thorite (?), were found in the stream gravels of the main branch of the South Fork of Quartz Creek, a tributary of the Kiwalik River. Although the bedrock source of the minerals was not located, the radioactive material was traced in slope wash well above the stream gravel. A detailed investigation of the area with more sensitive counters might reveal the source of the minerals and localities where the minerals are sufficiently concentrated to be minable.

Radiometric Examination of Rock Specimens from Mount McKinley, Alaska
Abstract: A suite of 50 rock specimens, collected by the 1947 Washburn Mount McKinley Expedition, was scanned radiometrically. The maximum radioactivity observed in any one of the specimens was about twice background. Radiometric analyses of the most radioactive samples show that a sample of vein quartz coated with manganese oxide contains 0.009 percent equivalent uranium and that the maximum equivalent uranium content of granitic rock types is .004 percent. The radioactivity of the manganese-stained quartz is probably due to traces of uranium in the manganese mineral, whereas that of the granitic rocks is due to radioactive accessory minerals.

Progress Report on Geologic Studies in the Capitol Reef Area, Wayne County, Utah
From abstract: During 1951 about 60 square miles of the Capitol Reef area, Wayne County, Utah, the northern end of the Waterpocket Fold, was mapped by plane-table methods on a scale of 1:62, 500. Formations, with an approximate aggregate thickness of 3, 200 feet, range from the Coconino sandstone of Permian age to the Navajo sandstone of Jurassic (?) age. About 35 linear miles of Shinarump conglomerate of Triassic age was examined in detail. Cliffs 900 to 1, 000 feet high form the west face of Capitol Reef, which is on the east and northeast flanks of a structural and topographic dome, The uranium deposits are in the basal part of the Shinarump conglomerate. Zippeite and metatorbernite are the uranium minerals found, and are associated with copper minerals, carbonaceous matter, clay beds, a thick bleached zone at the top of the Moenkopi formation, and channels or scours in the top of the Moenkopi. The highest radioactivity is in a clay bed at the base of the Shinarump conglomerate, and was detected at 7 localities between Grand Wash and Capitol Gorge, at the Birch Spring prospect in Moonie Draw, and at the Oyler mine in Grand Wash.

The Geological Survey's Work on the Geology of Uranium and Thorium Deposits
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 investigated in this study are embraced by five somewhat arbitrary groups of related types of deposits as follows: (1) Igneous rocks, pegmatites, veins, and related deposits; (2) Deposits in sandstone of carnotite, copper-uranium, and other minerals; (3) Other consolidated sedimentary rocks; (4) Placers; and (5) Natural fluids.

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.

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.
