Uraniferous Quartzite, Red Bluff Prospect, Gila County, Arizona
Abstract: Radioactive zones are present in the upper silty part of the pre-Cambrian Dripping Spring quartzite at the Red Bluff prospect, Gila County, Ariz. The prospect is in the SE 1/4 sec. 31, T. 5 N., R. 14 E., at the southern end of the Sierra Ancha area and 12 miles northeast of Roosevelt Dam. Stratigraphic control of the radioactive zones is indicated by the restriction of the zones to two layers, each about 20 feet thick.The zones are spatially associated in part with a diabase dike that occupies a fault, and in part with a thick diabase sill. The main uranium mineral disseminated through the rock in these zones has not been identified definitely, although minor quantities of secondary uranium minerals were observed. The results of scintillometer traverses and radiometric analyses indicate that the deposits probably contain an average of 0.026 percent uranium. Some black streaks and some fractures contain a higher percentage of uranium, but so far as is known the volume of such material is probably too small to affect the overall grade of the deposits.

Preliminary Appraisal of the Carnotite Resources of the Carrizo Mountains Area, San Juan County, New Mexico, and Apache County, Arizona
From introduction: A rapid appraisal of the carnotite resources of the Salt Wash sandstone member of the Morrison formation in the Carrizo Mountains area was undertaken by the U. S. Geological Survey late in 1951 in connection with its current project of geologic mapping of the area. Though brief and preliminary, this report provides a summary of production trends and estimated reserves in the area and indicates as far as possible the total potential of the area as a source of uranium. This information may be helpful in planning new milling facilities or other measures to encourage a higher rate of production.

Reconnaissance for Radioactivity in the Gold Hill Mining Area, Boulder County, Colorado, Part 1
Abstract: Several radioactive deposits were found as a result of reconnaissance in the Gold Hill mining area, Boulder County, Colo. The ore deposits of the area have been worked chiefly for gold. All ore shipped has come from fissure veins, most of which are gold telluride veins. There are, however, some important sulfide veins which show a vague zonal distribution of pyritic gold ores and silverlead ores. The results of this reconnaissance suggest a possible relationship of the radioactive deposits to this indistinct sulfide zoning; however, the zoning is so obscure that its practical application to prospecting for uranium is of doubtful value at the present time. Pitchblende, torbernite, metatorbernite, and schroeckingerite have been identified in specimens from the area; however, no uranium minerals have yet been identified from most of the radioactive deposits, and the uraniferous material present is probably in disseminated small particles. Although selected samples from several localities assay 0.10 percent uranium or more, the known deposits are small and probably are not of immediate economic importance

Preliminary Report on Geologic Investigations in Monument Valley Area, Arizona, 1952
From introduction: A program of uranium investigations and geologic mapping on the Navajo Indian Reservation in Apache and Navajo Counties, northeastern Arizona (fig. 1) was undertaken by the U. S. Geological Survey on behalf of the Atomic Energy Commission during the field seasons of 1951 and 1952. Field work on this program has been completed and preliminary copies of the maps, which cover an area of about 700 square miles, are inclosed as part of this report. The two principal objectives of the program were to establish geologic criteria useful as guides in prospecting for uranium deposits, and to appraise the favorableness of the Shinarump conglomerate and other Triassic rocks for the occurrence of uranium deposits in order to select areas that deserve exploration for concealed deposits.

Description of Core from Atomic Energy Commission Drill Hole Number 1, Project Gnome, Eddy County, New Mexico
From abstract: Drilling at the Project GNOME site, which is in the approximate center of sec. 34, T. 23 S., R. 30 E., NMPM, was undertaken in August and September 1958 by the W-W Drilling Company. The purpose of drilling this hole, which is at the precise location of the proposed shaft, was to determine (1) the lithologic and water-bearing characteristics of the rocks of Cenozoic, Mesozoic, and Paleozoic age that lie above the salt-bearing sequence in the Salado formation; (2) the depth to the top of the unleached salt and associated evaporites in the Salado formation; and (3) the local details of the salt-bearing sequence in the Salado formation.

Reconnaissance for Uranium in the Coal of São Paulo, Santa Catarina, and Rio Grande do Sul, Brazil
Abstract: Uranium-bearing coal and carbonaceous shale .of the Rio Bonito formation of Pennsylvanian age have been found in the States of Sao Paulo, Santa Catarina, and Rio Grande do Sul, Brazil. The uranium oxide content of the samples collected in the State of Sao Paulo ranges from 0.001 percent to 0.082 percent. The samples collected in Santa Catarina averaged about 0.002 percent uranium oxide; those collected in Rio Grande do Sul, about 0.003 percent uranium oxide. Since the field and laboratory investigations are still in their initial stages, only raw data on the radioactivity and uranium content of Brazilian coals are given in this report.

Engineering Geology Bearing on Harbor Site Selection Along the Northwest Coast of Alaska from Nome to Point Barrow
From abstract: This report describes geologic and oceanographic factors relevant to the selection of a site in northwestern Alaska, at which an experimental harbor can be created by the explosion of a nuclear device. Part I describes the results of a preliminary survey of the entire coastal and offshore region between Nome and Point Barrow: Part II consists of a more detailed evaluation of the Cape Thompson-Cape Seppings area; and Part III is a theoretical consideration of the effect of the ocean upon the temperature and distribution of permafrost. The report is based entirely upon the study of published and unpublished reports, field notes, and maps, interviews with the few geologists who have visited the region, and the interpretation of aerial photographs.

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.
