Reconnaissance for Uranium in the Powder River Basin, Wyoming

Description: Abstract: A reconnaissance was made of a large part of the Powder River Basin, Wyoming, during the summer of 1952 to search for uranium deposits in parts of the basin other than the Pumpkin Buttes area. No uranium deposits of economic interest were found, but some rocks of the Tertiary Fort Union formation and the Cretaceous Inyan Kara group were found to be sufficiently uraniferous to justify further search in rocks of these units. Analyses of samples of sandstones, baked shales, and siltstones taken during the reconnaissance show these rocks are considerably more vanadiferous than the average sandstone, or clay and shale.

The Stratigraphy of the Upper Part of the Bone Valley Formation and its Relation to the Leached Zone

Description: From abstract: The two topmost zones of the Bone Valley formation at the Homeland mine are a phosphate-cemented quartz sandstone and an underlying pebbly and clayey quartz and phosphate sand characterized by graded bedding. This sequence is found in every other area of the land-pebble field. Therefore, these zones are considered to be stratigraphic units and the transition between them to be a key horizon.

Results of U.S. Geological Survey Exploration for Uranium-Vanadium Deposits in the Club Mesa Area, Uravan District, Montrose County, Colorado

Description: From introduction: This report summarizes some of the results of U. S. Geological Survey investigations in the Club Mesa area and presents a compilation of available geologic data that would be helpful in future exploration. Detailed geologic logs of U. S. Geological Survey holes drilled in the Club Mesa area on public land that is no longer withdrawn from mineral entry are on open file for public inspection in the U. S. Geological Survey office, Grand Junction, Colorado.

Liquid-in-Glass Thermometer Calibration Service

Description: Abstract: This document gives a description of the calibration of liquid-in-glass thermometers at the National Bureau of Standards. The calibration equipment and procedures used at NBS are discussed in detail. Calculations and stem-temperature corrections are shown and a discussion of the sources of error encountered in calibration and estimates of uncertainties is presented.

Criteria for the Installation of Energy Conservation Measures

Description: From abstract: Standard installation practices were developed to assist in assuring the effectiveness and safety of energy conservation measures installed under the Residential Conservation Service (RCS). They serve as mandatory standards under RCS but are recommended guides for all installations of the covered materials and products. The criteria are being used by DoE to develop training manuals for installers, inspectors, and energy auditors.

Pitchblende Deposits at the Wood and Calhoun Mines, Central City Mining District, Gilpin County, Colorado

Description: From introduction: The purpose of this work was to determine the distribution and reserves of pitchblende in the veins. These particular mines were selected because the other mines that had produced pitchblende in the east were either inaccessible, or accessible under such adverse conditions as to make detailed mapping impracticable.

Interim Report on Exploration in the Yellow Cat Area, Grand County, Utah

Description: From introduction: This report summarizes the results of diamond-drill and wagon-drill exploration by the U. S. Geological Survey in the Yellow Cat area from October 9, 1951, to May 22, 1952. The Yellow Cat area is about 10 miles southeast of Thompsons, Grand County, Utah. It is accessable by two graded roads which leave U. S. Highway 50 at points 5 miles east of Thompsons and 7 miles west of Cisco, Utah. A sampling plant and purchasing depot, belonging to the United States Vanadium Co., is at Thompsons. The explored ground includes about 8 square miles principally in T. 22 S., R. 22 E., and the northern part of T. 23 S., R. 22 E., Salt Lake meridian (fig. 1). Altitudes in the area range from about 4, 600 feet to 5, 100 feet (datum is assumed but is approximately correct), and the relief is moderate.

Results of Exploration at the Old Leyden Coal Mine, Jefferson County, Colorado

Description: From abstract: Six diamond-core holes totaling 2, 201 feet were drilled by the U. S. Bureau of Mines under contract to the U. S. Atomic Energy Commission at the Old Leyden coal mine, Jefferson County, Colo. The holes were spotted on the basis of geologic mapping by the U. S. Geological survey and were drilled to explore the lateral and downward extent of a uranium-bearing coal and the associated carnotite deposits in the adjacent sandstone. The data obtained from the diamond-core holes helped to explain the geology and structural control of the deposit. The uranium is most abundant in a coal bed that in places has been brecciated by shearing, and then altered to a hard, dense, and silicified rock. The uraniferous coal is in the nearly vertical beds of the Laramie formation of Upper Cretaceous age,

Uranium Deposits on the Bulloch Group of Claims, Kane County, Utah

Description: From abstract: The Bulloch group of uranium claims are in T. 40 S., R. 9 we, Kane County, Utah. The past production has been 8.5 tons of submarginal ore submitted to the Marysvale purchasing depot of the Atomic Energy Commission in 1950; this shipment assayed 0.16 percent U308, Uranium is finely disseminated in clay, carbonaceous clay, carbonized wood fragments, iron-oxide concretions, petrified logs, sandstone, and conglomerates of the lower part of"the Dakota sandstone and upper part of the Summerville formation. Small quantities of carnotite, autunite, and torbernite are exposed in the conglomerate and sandstone on Lynn Nos. 2 and 3 claims.

Preliminary Report on 1952 Field Investigations in Wet Mountains, Colorado

Description: From page 3: A metallogenic province containing thorium in veins in pre-Cambrian rocks along the western slope of the Wet Mountains, Colo. found by the Reconnaissance Group of the U. S. Geological Survey during the summer of 1950,was revealed by the discovery during fiscal-years 1951-1952 of seventeen radioactive deposits scattered along a north-northwest linear distance of twenty miles. All the thorium occurrences were found within terrain that has never been geologically mapped. Three of the most promising localities were mapped at 1:1,200, and a diamond-drilling program was conducted at Haputa ranch.

Preliminary Report on Geologic Studies in the Red House Cliffs Area, San Juan County, Utah

Description: From introduction: The main objectives of the Red House Cliffs project are to appraise the uranium possibilities of the area, to determine the areal distribution and character of the ore-bearing Shinarump conglomerate and to prepare a geologic map of the area. The purpose of this preliminary report on the Red House Cliffs project is to summarize results of the field work done from July 6, 1952, to October 31, 1952, and to present plans for future work on the project. This work was done on behalf of the U. S. Atomic Energy Commission.
