Geologic Summary of the Central Valley of California with Reference to the Disposal of Radioactive Waste

Description: From introduction: This report describes the geology of the area only to the extent necessary for preliminary evaluation of the possibilities for the disposal of liquid radioactive waste by injection through deep wells. Their value will increase with development of extensive commercial production of atomic power and attendant creation of radioactive waste from the processing of spent fuel elements. The disposal of liquid waste in deep reservoirs is only one of several possibilities that must be considered.

The Geological Survey's Work on the Geology of Uranium and Thorium Deposits

Description: From abstract: The Geological Survey has been studying the geology of uranium and thorium continuously since 1939, when it began a comprehensive investigation of the vanadium-uranium deposits of the Colorado Plateau. Greatly increased demand for uranium arising from the advent of controlled fission in 1942 resulted in widening of the study in 1944 to include other possible sources and in further expansion on behalf of the U. S. Atomic Energy Commission since 1947. The wide variety of materials investigated in this study are embraced by five somewhat arbitrary groups of related types of deposits as follows: (1) Igneous rocks, pegmatites, veins, and related deposits; (2) Deposits in sandstone of carnotite, copper-uranium, and other minerals; (3) Other consolidated sedimentary rocks; (4) Placers; and (5) Natural fluids.

Occurrences of Uranium-Bearing Minerals in the St. Kevin District, Lake County, Colorado

Description: From abstract: Two hundred and seventy-one prospect pits, mine dumps, or mine workings within the Sugar Loaf-St. Kevin mining districts and vicinity, were tested for radioactivity by the U. S. Geological Survey in 1951 during six weeks of investigation on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission. One hundred and twenty-two weak radioactivity anomalies were found in the St. Kevin district and vicinity, and eight slight anomalies were noted in"-the Sugar Loaf district, which adjoins the St. Kevin district on the south, Most of the radioactivity anomalies were found in igneous and metamorphic rocks of pre=Cambrian age, but some were found in metalliferous veins of Tertiary age.

Geology and Uranium Occurrences in the Miller Hill Area, Carbon County, Wyoming

Description: 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.

Airborne Radioactivity Surveys for Phosphate in Florida

Description: Introduction: Deposits of phosphate in Florida, located beyond the limits of known producing areas, have been reported by prospectors and mining companies. Much of the information has been based upon prospecting and exploration which was undertaken many years ago and as a result the published data relating to the occurrence of these deposits are fragmentary, and few details relating to specific locations and extent are available.

Results of Reconnaissance for Radioactivity in Parts of the Alma District, Park County, Colorado

Description: 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.

Carnotite Resources of San Miguel Bench, Montrose County, Colorado

Description: Abstract: San Miguel bench includes about 4 square miles in the southern part of T. 48 N., R. 17 W., New Mexico principal meridian, Montrose County, Colorado. Production of carnotite ore from the area has been about 15, 000 short tons having an estimated average graderof 0. 31 percent U3O8,and 1. 6 percent V2 05 Nearly all of the carnotite deposits occur in a single-continuous sandstone bed near the top of the Salt Wash member of the Jurassic Morrison formation. These deposits consist chiefly of sandstone impregnated with uranium- and vanadium-bearing minerals. They are irregular tabular-shaped masses ranging in size from a few short tons to 30, 000 short tons or more of minable carnotite ore. During the period November 27, 1951, to April 17, 1953, the U. S. Geological Survey drilled 309 holes totaling 92, 194 feet on the San Miguel bench. Reserves total about 43, 000 short tons of material 1 foot or more thick and contain 0,.10 percent or more U30 or 1. 0 percent or more V205. Of these reserves 3, 300 short tons occur in private land. These reserves are in ten deposits found by Geological Survey drilling. Potential reserves (reserves based on geologic evidence only) are predicted to total about 15, 000 short tons, averaging 0.30 percent U308 and 1.6 percent V2 05 No additional exploration drilling in the San Miguel bench is planned by the Geological Survey. Some drilling by private enterprise is recommended.

Uranium-Bearing Copper Deposits in the Coyote District, Mora County, New Mexico

Description: Abstract: Uranium-bearing copper deposits occur in steeply dipping beds of the Sangre de Cristo formation of Pennsylvanian and Permian age south of Coyote, Mora County, N. Mex. Mapping and sampling of these deposits indicate that they occur in lenticular carbonaceous zones in shales and arkosic sandstones. Samples from these zones contain as much as 0.067 percent uranium and average 3 percent copper. Metatyuyamunite is disseminated in some of the arkosic sandstone beds, and uraninite was identified in some of the copper sulfide nodules occurring in the shale. In polished section these sulfide nodules were found to be composed principally of chalcocite with some bornite and covellite, as well as pyrite and malachite. Most of the samples were collected near the surface from the weathered zone. The copper and uranium were probably deposited with the sediments and concentrated into zones during compaction and lithification. Carbonaceous material in the Sangre de Cristo formation provided the environment that precipitated uranium and copper from mineral-charged connate waters forced from the clayey sediments.
