Greens Creek Uranium Occurrence, Marquette County, Michigan (open access)

Greens Creek Uranium Occurrence, Marquette County, Michigan

From abstract: Metatorbernite and bassetite are present in altered carbonaceous and quartzose slate of probable upper Huronian age. The slate is part of a small inlier of Huronian rocks between the Gwinn iron district to the southeast and the Marquette iron district to the northwest, Marquette County, Mich. Samples taken from a shallow trench, which was dug in the area of highest radioactivity, contained as much as 0.68 percent uranium. A 4-foot channel sample of the slate contained 0.036 percent uranium.

Reconnaissance for a Uranothorianite-Bearing Lode in the Vicinity of the Headwaters of the Peace River, Candle Quadrangle, Seward Peninsula, Alaska (open access)

Reconnaissance for a Uranothorianite-Bearing Lode in the Vicinity of the Headwaters of the Peace River, Candle Quadrangle, Seward Peninsula, Alaska

From abstract: Reconnaissance in 1947 found uranothorianite and gummite associated with copper sulfides, iron oxides, molybdenite, gold, silver, bismuth, and thorite in placers of a headwater tributary of the Peace River in the eastern part of the Seward Peninsula, Alaska. Brief radiometric reconnaissance early in the summer of 1952 failed to locate the bedrock source of the radioactive minerals at the head of the Peace River, primarily because of the shielding-effect of widespread tundra cover. The samples obtained in 1952 indicate the presence of galena, sphalerite, pyrrhotite, covellite, and fluorite in addition to the minerals reported in the results of the 1947 reconnaissance.

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

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

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.

The Occurrence of Zeunerite at Brooks Mountains, Seward Peninsula, Alaska (open access)

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.

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.

Geology and Uranium Deposits of Part of the Browns Park Formation, Colorado, Wyoming, and Utah: a Preliminary Report (open access)

Geology and Uranium Deposits of Part of the Browns Park Formation, Colorado, Wyoming, and Utah: a Preliminary Report

From abstract: Uranium deposits and radioactivity anomalies have been found in the eastern half of the area underlain by the Browns Park formation in northwestern Colorado, south-central Wyoming, and northeastern Utah. The deposits are in eolian, lacustrine, and fluvial sandstones, tuffaceous sandstones, and limestones all of which were deposited on two converging pediments during Miocene time. At least one eastern and one western facies of lacustrine and fluvial sedimentary rocks are separated by a belt of eolian sandstones. The faces may be distinguished in the field and by petrographic and heavy-mineral studies in the laboratory.
