Lost Creek (Wamsutter) Schroeckingerite Deposit, Sweetwater County, Wyoming

Description: Summary: The Lost Creek schroeckingerite deposit in Sweetwater County, Wyo., has attracted attention in the past both as an occurrence of comparatively rare minerals and more recently as a possible source of uranium ore. During the summer of 1948 a newly-formed company by the name of Uranium, Inc., explored part of the deposit by bulldozer trenching and drilling. under the technical direction of the Minerals Engineering Company of Grand Junction, Colo. Examination of the significant exposures of the schroeckingerite deposit indicated that the uraniferous beds are discontinuous and that their areal distribution is erratic. The overburden has an average thickness of 2.5 feet.

Notes on the Relationship of Uranium Mineralization and Rhyolite in the Marysvale Area, Utah

Description: From abstract: A study, consisting of field and laboratory work, was undertaken in an endeavor to establish possible structural mineralization controls associated with the copper-uranium occurrences in the Willaha area, Coconino County, Arizona. Uranium mineralization, apparent at present, is localized along small fissures and vugs and in certain beds and lenses of the middle member of the Kaibab formation(Permian). It is associated with copper and iron oxide staining. Though no definite ore controls were disclosed by this study, at least a limited program of shallow drilling is warranted on the property. This sub-surface exploration should determine possible extensions of known mineralized areas, explore surface radiometric anomalies, and provide data for the determination of possible guides to ore. Deeper exploration may encounter mineralization in other horizons of the Kaibab limestone.

Preliminary Report on Uranium Occurrence, Silver King Claims, Tooele County, Utah

Description: Abstract: Uranium was discovered on the Silver King claims in the fall of 1953. The claims are on the west flank of the Sheeprock Mountains in the eastern part of the Erickson mining district, Tooele County, Utah. Uraninite occurs in north- to northwest-trending copper-nickel-silver bearing fissure veins near the margin of a granitic stock of probable late Tertiary age. Sedimentary rocks in contact with the granite are chiefly dolomite and quartzite of Middle and Upper Ordovician age. Diamond drilling on this property did not disclose significant amounts of uranium; however, encouraging showings have been found by underground exploration by the owner.

Investigation of Subsurface Isorad Methods, Temple Mountain, San Rafael District, Utah

Description: From abstract: The subsurface isorad method is an attempt to locate areas favorable for uranium ores by the use of contour maps which show localities having greater radioactivity. The construction of isorad maps entails the measurement of the area under the curve of a gamma-ray logo The figures obtained indicate relative amounts of gamma radiation and are used to locate the isorad contours. This work was started at Temple Mountain in the San Rafael Swell area during the spring of 1952. The purpose of this investigation is to determine the most effective and economic hole spacing for subsurface isorad work.

Knob Creek Monazite Placer, Cleveland County, North Carolina

Description: From abstract: The area comprising the first flood plain downstream from the headwaters of Knob Creek was one of three monazite placer deposits near Shelby, N. C., recommended by the Geological Survey for investigation by the Bureau of Mines as a joint effort by the above two agencies. Past production of monazite from the headwaters of this stream and its drainage of an area of known source rocks were factors influencing this selection. Drilling of the deposit was started on November 26, 1951, and completed December 29, 1951. Twenty-two churn-drill holes were completed to bed-rock on 112 acres of this flood plain for a total depth of 433 feet of vertical drilling.

Preliminary Reconnaissance of the Dripping Spring Quartzite Formation in Gila and Pinal Counties, Arizona

Description: Abstract: A four-week reconnaissance of certain portions of the mountainous area in Gila and Pinal Counties, Arizona, was undertaken in March and April, 1953, to inspect accessible outcrops of Dripping Spring quartzite, a pre-Cambrian formation which has lately attracted the interest of the Atomic Energy Commission by the discovery of two separate occurrences of uranium mineralization. Although no new deposits were found during the field work, a more thorough examination of the quartzite seems warranted. Recommendations for further prospecting by airborne and ground methods are presented in this report, and are based largely on observations made during the brief visit.

Uraniferous Coal and Carbonaceous Shale in Northeast Paraná, Brazil

Description: From abstract: Uraniferous coal has been found in northeast Parana', Brazil, in the Rio Bonito formation of Pennsylvanian age. In the majority of coal samples taken the uranium oxide content ranges from 0.005 to 0.030 percent, but selected screened samples have contained as much as 0.45 percent uranium oxide. The sampled thickness of the coal seam ranges from 17 to 54 centimeters and averages 31 centimeters. Channel samples across the entire thickness of the coal zone were taken in two places. All other samples were taken as grab samples from either mine waste dumps or coal zones that had high radioactivity.

Tectonic Map of Eastern Montana Showing the Distribution of Uranium Deposits

Description: From introduction: A tectonic map for the northern part of the Cordilleran Foreland was compiled to aid in establishing the geologic setting of uranium deposits within the region, and to determine what relationships, if any, exist between the distribution of uranium deposits and localities, and the regional tectonic pattern (Osterwald, 1955). The relationships might suggest new areas favorable for the discovery of uranium deposits in the Cordilleran Foreland as well as in other areas with similar tectonic history. The map will show the distribution of crest lines and troughs of folds, faults, uranium deposits and localities, and areas of volcanic activity. Outcrop areas of Precambrian and post-Eocene rocks are shown to designate the relative age of structures. Where possible the Precambrian rocks are subdivided into structural types, so that their influence on younger deformations may be inferred. The map of eastern Montana is one of a series being prepared before the final map is assembled (fig. 1.).

Progress on Geologic Studies in the Capitol Reef Area, Wayne and Garfield Counties, Utah

Description: From introduction: Objectives of the geologic studies and mapping in this area are: 1) to study and map geologic formations in which uranium ore may be found with special attention given to the Triassic Shinarump conglomerate, 2) to evaluate uranium deposits and to study local controls and habits of ore, 3) to collect and study geologic data basic to an understanding of regional geologic trends or controls in the distribution of the ore deposits, and 4) to determine the favorableness of the area for concealed deposits of uranium. The present report does not attempt to provide answers to all these objectives. Rather, it is a brief explanatory report to accompany the geologic map (fig. 2) and make it available in advance of the final report.
