From abstract: A reconnaissance to determine the uranium content of granitic rocks in the western states was made during parts of October and November 1951. The paucity of our knowledge of the granitic rocks that are most likely to contain significant quantities of uranium has prevented all but a very general isolation of areas or types of granitic rocks for reconnaissance examination.

From abstract: The Mineral Hill monazite deposits, 3 to 5 miles northeast of the town of Shoup, Lemhi County, Idaho, were investigated by the U. S. Geological Survey in July 1952. The deposits are replacement veins and lenses along shears in a pendant, principally of pre-Cambrian biotite gniess, about 4 to 5 miles in size and enclosed by granite of the Idaho batholith. The veins consist predominantly of calcite, monazite, and allanite, and contain minor quantities of barite, magnetite, rutile, and apatite.

Abstract: The absorber plant method of geobotanical prospecting was tested systematically over the bench formed by the Jurassic Todilto limestone on the south flank of Haystack Butte, McKinley County, N. Mex. This portion of the bench includes the largest known uranium ore body in limestone and most has been extensively drilled by private enterprise. Geobotanical prospecting was accomplished to provide control data. Comparison of the geobotanical anomalies with the available drill hole information from the mining companies and Atomic Energy Commission geologists have shown that the known ore occurrences would have been outlined by the results of the tree sampling. In addition some geobotanical anomalies are indicated in drilled areas in which ore was not reported and in areas not physically explored at the time of sampling. These anomalies may represent mineralized ground below ore grade or new ore deposits.

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.

Report discussing the U.S. Geological Survey's reconnaissance for radioactivity in thirty-four metal-mining districts of the San Juan Mountains, Colorado during 1951-1953. General geology of the area, methods of reconnaissance, and results of the reconnaissance are included.

"A reconnaissance for radioactive minerals in the San Juan Mountains, Colo. (fig. 1), was started in the western part by W.S. Burbank and C.T. Pierson in 1951, and continued in 1952 by Pierson, W.F. Weeks, and F.J. Kleinhampl, and in 1953 by Pierson and T.H.W. Loomis of the U.S. Atomic Energy Commission in the western part of the mountains in reconnaissance and in examination of a pitchblende occurrence found by Loomis. The work on which this paper is based was done by the Geological Survey on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission."

From abstract: "The Crevasse Canyon formation and Point Lookout(?) sandstone of Late Cretaceous age and the Baca and Datil formations of Tertiary age were mapped in an area of 168 square miles in the upper Alamosa Creek Valley along the northern edge of the Datil Mountains, Catron County, N. Mex. The investigation was made to determine the potentialities of the area for producing uranium and to learn the geologic controls for the concentration of uranium."

From introduction: "This report was compiled to bring together the well data collected by the U.S. Geological Survey since 1960. This compilation includes data on 63 wells and test holes which were drilled since the Moore reports were prepared, or which were deepened or otherwise modified since 1960."

Recycling water within the local ground-water system is an effective means to increase quantity and control water temperature of the water supply and to control or avoid environmental pollution. A fish-rearing facility, operated for 15 months, returned water to the local ground-water system through an infiltration pond and recycled 83 percent of its water supply. For each 100 gallons pumped the net stress on the aquifer was equivalent to withdrawing 17 gallons. Despite recycling, nutrient content and temperature of the water supply were acceptable throughout the study period. The rearing-facility nutrient output ranged from 1 to 2 pounds of nitrate-nitrogen per day, but nitrate-nitrogen levels in the water supply remained below 4 mg/1. The water temperature ranged from 7°C to 14°C. Mathematical relations developed show that acceptable nitrate-nitrogen levels and water temperatures nearly optimum for salmonid rearing could be maintained during full-scale hatchery operation.

Abstract: "Monazite placers in the western Piedmont of North and South Carolina were explored by the U. S. Geological Survey in 1951-54 and are estimated to contain at least 53,000 short tons of ThO2 and 4,600 short tons of U3O8. None of these deposits is being mined."

Abstract: Pitchblende was discovered in July 1951 in the Alma mining district, Park County, Colo0 , by the U0 S. Geological Survey acting on behalf of the U. So Atomic Energy Commission. The pitchblende is associated with Tertiary veins of three different geologic environments: 1) veins in pre-Cambrian rocks, 2) the London vein system the footwall block of the London fault, and 3) veins in a mineralized area east of the Cooper Gulch fault. Pitchblende is probably not associated with silver-lead replacement deposits in dolomite. Secondary uranium minerals, as yet undetermined, are associated with pitchblende on two London vein system mine dumps, and occur in oxidized vein material.Lfrom dumps of mines in the other environments. Although none of the known occurrences are of commercial importance, the Alma district is considered a moderately favorable area in which to prospect for uranium ore, because twenty-four of the forty-three localities examined show anomalous radioactivity; samples from anomalously radioactive localities, which include mine dumps and some underground workings, have uranium contents ranging from 0.001 to l.66 percent.
