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

Reconnaissance for Trace Elements in North Dakota and Eastern Montana
From abstract: A reconnaissance for sources of radioactive material in North Dakota and eastern Montana was made in 1948. This reconnaissance was followed by a more detailed survey of parts of Golden Valley and Slope counties, southwestern North Dakota, in June 1949. The radioactivity of representative sections of all formations known to be exposed in the area and of three manganiferous spring deposits was determined with portable Geiger-Mueller counters. At 86 localities 82 samples were taken of these formations and also of 10 ground and surface waters.

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.

Forty-Niner, King Solomon Ridge, and West End Claims Near Clancy, Jefferson County, Montana
Abstract: Secondary minerals of the uranite group occur in dense quartz veins and in altered aplitic granite along and near the crest of the east-trending ridge about one mile west of Clancy, Montana. Brief examination suggests that the radioactive minerals are erratically distributed, but a more thorough study of the area will be made by the Geological Survey during the coming field season.

Trace Elements Reconnaissance in the Jakolof Bay Area, Southern Alaska
Abstract: "As a result of inquiries by prospectors in 1948 concerning radioactive ores in the vicinity of Jakolof Bay on the Kenai Peninsula in southern Alaska, the Geological Survey conducted a brief investigation during 1949. No radioactive material was found. Possibly a chromite stockpile in this locality was mistaken for pitchblades."

Radioactive Fluorite in the Thomas Range, Juab County, Utah
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. Spor, Ray Spor, and Chad Spor; Albert Willden and Earl Willden; T. A. Claridge; and W. E. Black and F. B. Chesley were the only groups producing fluorite in the district in August 1950.

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

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.
