Trace Elements Reconnaissance on the South Fork of Quartz Creek, Northeastern Seward Peninsula, Alaska (open access)

Trace Elements Reconnaissance on the South Fork of Quartz Creek, Northeastern Seward Peninsula, Alaska

Abstract: Two uranium-bearing minerals, uranothorianite and thorite (?), were found in the stream gravels of the main branch of the South Fork of Quartz Creek, a tributary of the Kiwalik River. Although the bedrock source of the minerals was not located, the radioactive material was traced in slope wash well above the stream gravel. A detailed investigation of the area with more sensitive counters might reveal the source of the minerals and localities where the minerals are sufficiently concentrated to be minable.

Radiometric Examination of Rock Specimens from Mount McKinley, Alaska (open access)

Radiometric Examination of Rock Specimens from Mount McKinley, Alaska

Abstract: A suite of 50 rock specimens, collected by the 1947 Washburn Mount McKinley Expedition, was scanned radiometrically. The maximum radioactivity observed in any one of the specimens was about twice background. Radiometric analyses of the most radioactive samples show that a sample of vein quartz coated with manganese oxide contains 0.009 percent equivalent uranium and that the maximum equivalent uranium content of granitic rock types is .004 percent. The radioactivity of the manganese-stained quartz is probably due to traces of uranium in the manganese mineral, whereas that of the granitic rocks is due to radioactive accessory minerals.

Uranium-Bearing Sandstone in the White River Badlands, Pennington County, South Dakota (open access)

Uranium-Bearing Sandstone in the White River Badlands, Pennington County, South Dakota

From abstract: The uranium mineral uranocircite, a barium uranyl phosphate, occurs in a sandstone channel in the Chadron formation of Oligocene age in the White River Badlands, Pennington County, S. Dak. A vertical section of the basal 1-foot of the channel contains 0. 25 percent uranium. There are also small amounts of metatyuyamunite (?) in the upper part of a freshwater lime stone bed in the Chadron formation and carnotite in chalcedony veins in the overlying Brule formation, also of Oligocene age.

Preliminary Report on the Rimini Area, Jefferson City Quadrangle, Jefferson County and Lewis and Clark County, Montana (open access)

Preliminary Report on the Rimini Area, Jefferson City Quadrangle, Jefferson County and Lewis and Clark County, Montana

Abstract: A number of radioactivity anomalies and secondary uranium minerals have been found in the Rimini area near the northwestern margin of the Boulder batholith. Most of the anomalies are associated with chalcedonic vein zones that consist of one or more veins of cryptocrystalline and fine-grained quartz in silicified quartz monzonite and alaskite. Seventeen of the anomalies were found along veins that contain base and precious metals; nine were along veins in the vicinity of the village of Rimini from which there has been production of lead, silver, zinc, and gold.

Progress Report on Geologic Studies in the Capitol Reef Area, Wayne County, Utah (open access)

Progress Report on Geologic Studies in the Capitol Reef Area, Wayne County, Utah

From abstract: During 1951 about 60 square miles of the Capitol Reef area, Wayne County, Utah, the northern end of the Waterpocket Fold, was mapped by plane-table methods on a scale of 1:62, 500. Formations, with an approximate aggregate thickness of 3, 200 feet, range from the Coconino sandstone of Permian age to the Navajo sandstone of Jurassic (?) age. About 35 linear miles of Shinarump conglomerate of Triassic age was examined in detail. Cliffs 900 to 1, 000 feet high form the west face of Capitol Reef, which is on the east and northeast flanks of a structural and topographic dome, The uranium deposits are in the basal part of the Shinarump conglomerate. Zippeite and metatorbernite are the uranium minerals found, and are associated with copper minerals, carbonaceous matter, clay beds, a thick bleached zone at the top of the Moenkopi formation, and channels or scours in the top of the Moenkopi. The highest radioactivity is in a clay bed at the base of the Shinarump conglomerate, and was detected at 7 localities between Grand Wash and Capitol Gorge, at the Birch Spring prospect in Moonie Draw, and at the Oyler mine in Grand Wash.

The Geological Survey's Work on the Geology of Uranium and Thorium Deposits (open access)

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

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.

Distribution and Origin of Phosphate in the Land-Pebble Phosphate District of Florida

From abstract: The land-pebble phosphate district of Florida is a part of the Gulf Coastal Plain. The geologic formations cropping out in the district are the Miocene Hawthorn, Pliocene Bone Valley, and Pleistocene terrace sands. The Bone Valley formation consists of a lower strongly phosphatic unit and an upper less phosphatic unit. This paper is concerned principally with the lower unit, which contains the bulk of the minable phosphate deposits of the district.

Reconnaissance for Uranium in the Lost River Area, Seward Peninsula, Alaska (open access)

Reconnaissance for Uranium in the Lost River Area, Seward Peninsula, Alaska

Abstract: Reconnaissance for uranium in the Lost River area, Seward Peninsula, Alaska, during the 1951 field season revealed the presence of minor amounts of radioactive material in mineralized portions of rhyolitic dikes and in a small iron-enriched zone in limestone. The dikes contain as much as 0.01 percent equivalent uranium locally and average 00005 percent equivalent uranium. The radioactive material occurs as a secondary hematitic coating of the dike rock. The iron-enriched zone has an average content of about 0.06 percent equivalent uranium with the radioactive material occuring in limonite, hematite, goethite, and mimetite. The radioactivity of these minerals is due to the presence of uranium as an impurity. No uranium deposits of economic importance were found.

Relation of Uranium to Hypogene Mineral Zoning in the Front Range Mineral Belt, Colorado (open access)

Relation of Uranium to Hypogene Mineral Zoning in the Front Range Mineral Belt, Colorado

From abstract: Many of the mining districts of the Colorado Front Range mineral belt contain mesothermal sulfide ores that exhibit a zonal distribution. Present data indicate that in most of the zoned districts pitchblende and/or secondary uranium minerals are most abundant in a transition zone between central areas containing predominantly pyritic gold ores and peripheral areas containing dominantly lead-zinc-silver deposits. Copper in the form of chalcopyrite is also probably more abundant in the transition zone than in adjacent zones.

Airborne Radioactivity Surveys for Phosphate in Florida

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.
