Reconnaissance of Some Geologic Formations in Southeastern Idaho, Western Wyoming, and Northern Utah

Description: Abstract: A radiometric reconnaissance, using a portable beta-gamma survey meter, of some geologic formations ranging in age from Cambrian to Cretaceous, and springs in southeastern Idaho, western Wyoming, and northern Utah, has shown that none of them are sufficiently radioactive to warrant further examination of them in the area.

Radioactive Fluorite in the Thomas Range, Juab County, Utah

Description: From abstract: The Thomas Range fluorite district, on Spor's Mountain in the western part of the Thomas Range, Juab County, Utah, is approximately 6 miles long and 2 miles wide, and contains almost no unclaimed land. The fluorite production of the district, since its discovery in 1943, has been 35,700 short tons. It was obtained from 12 different ore bodies on eight different properties. G. P.

Radioactivity in the "Okpilak" Gneissic Granite Mount Michelson Area, Northeastern Alaska

Description: The following report discusses radioactive results found in 4 samples of gneissic granite of 13 samples collected from the Mount Michelson area of northeastern Alaska. A mineralogic study of all heavy-mineral fractions having more than 0.01 percent equivalent uranium indicates that the radioactive material apparently is confined to biotite, which in one sample contains 1.19 percent uranium.

Uraniferous Quartzite, Red Bluff Prospect, Gila County, Arizona

Description: 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… more

Geology of Carnotite-Bearing Sandstone in the Uravan and Gateway Districts, Montrose and Mesa Counties, Colorado, and Grand County, Utah

Description: From Introduction: "In the Uravan and Gateway districts, the general character of the bedding in the ore-bearing sandstone and amount of alteration in associated mudstones, and the relation of these to each other, are the features most useful as large-scale guides. This report describes these features and their distribution, as well as some other significant geologic characteristics of the ore-bearing sandstone."

A Preliminary Determination of the Age of Some Colorado Plateau Uranium Ores by the Lead-Uranium Method

Description: Report discussing a geological investigation of the age of Colorado Plateau uranium ores using the lead-uranium methods. The objective of the study was to determine whether the uranium deposits in the Shinarump conglomerate are late Triassic and that those in the Morrison formation are late Jurassic, or whether all deposits are late Cretaceous to early Tertiary.
