Reconnaissance for Radioactivity in the Yuma Air Force Base Gunnery Range, Yuma County, Arizona

Description: From abstract: During part of February and March 1953, reconnaissance examinations for radioactive material were made at 12 localities in the Yuma Air Force Base gunnery range in southern Yuma County, Ariz. The Yuma gunnery range, which is adjacent to the west edge of the Luke and Williams Air Force Bases gunnery range, is characterized by block faulted, elongate mountain ranges composed essentially of schist, gneiss, and granite of pre-Cambrian to Mesozoic age and separated by broad alluvial basins.

Reconnaissance for Radioactive Material in the Shinarump Conglomerate at Balanced Rock Anticline, San Juan County, Utah

Description: Abstract: A reconnaissance for radioactive minerals in the Shinarump conglomerate of Triassic age exposed north of the San Juan River at Balanced Rock anticline was made in July 1953. The purpose of the reconnaissance was to search for any exposed uranium minerals and to determine the favorability of the Shinarump for accumulation of uranium-ore deposits. No uranium minerals or places of abnormally high radioactivity were observed. However, nine exposed channels at the base of the Shinarump conglomerate and other channels, probably present where the base of the Shinarump is concealed, indicate the Shinarump may be favorable for uranium-ore deposits.

Preliminary Report on the Geology and Uranium Deposits of South Elk Ridge, San Juan County, Utah

Description: From abstract: Elk Ridge is in southeastern Utah in the central part of San Juan County. It forms a conspicuous ridge on the north end of the Monument upwarp. During the summer of 1953 field work was largely restricted to South Elk Ridge, that part of Elk Ridge which is south of The Notch. Permian and Triassic sedimentary rocks crop out in the area and Jurassic and Cretaceous rocks are exposed east of the area.

Geology of the Ogotoruk Creek Area, Northwestern Alaska

Description: From introduction: A project to use the immense energy concentrated in a nuclear device to construct an experimental deep-water harbor has been proposed by the Atomic Energy Commission and is referred to as Project Chariot; it is one phase of AEC Project Plowshare...During the field conference, Mr. Gerald Johnson of U.

Tectonic Map of Wyoming, East of the Overthrust Belt, Showing the Distribution of Uranium Deposits

Description: From introduction: The compilation of the tectonic map of Wyoming east of the overthrust belt (area 6, fig. 2) was done by the U. S. Geological Survey on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission. Structures shown on the map have been obtained from published geologic maps and from unpublished data supplied by Government agencies, private companies, and independent geologists. The tectonic map of Wyoming east of the overthrust belt is only a progress report; any suggestions for corrections or additions will be appreciated.

Simplified Geologic Map Showing Uranium Deposits and Principal Ore-Bearing Formations of the North Central Cordilleran Foreland Region

Description: From introduction: The Cordilleran Foreland has been defined by Osterwald (1956, p. 1) as "a region containing distinctive structural elements that forms a broad north-south belt parallel to and east of the Cordilleran geanticline...." The location of these tectonic regions is shown in figure 4 of this report. region are an important potential source of uranium in the United States. The accompanying maps (figs. 1, 2, and 3) show the location of most of the known uranium deposits and the localities from which samples, containing 0.01 or more percent uranium, or uranium minerals, have been obtained. The outcrop patterns of the principal ore-bearing formations are from the sources indexed on each map.

Preliminary Report on the Geology of the Tiger (Hideout) Claim, White Canyon Area, San Juan County, Utah, with Recommendations for Exploration for Geologic Information

Description: From introduction: The purpose of the mapping was to study the habits of the uranium minerals with relation to the geologic features of the White Canyon area, The work has been done by the U. S. Geological Survey on behalf of the Atomic Energy Commission. The Tiger claim is recommended for exploration by diamond drilling to obtain geologic information on the trend, length, depth, and width of the scour channel, and the relationship of uranium and copper minerals to the Shinarump-filled channel and to fractures.

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.

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.

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,

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.
