From abstract: Radium-bearing precipitates derived from 'oil-well fluids have been found in more than 60 oil and gas fields in Cowley, Butler, Marion, Sedgwick, and Greenwood Counties of southeastern Kansas. The abnormal radioactivity of these precipitates has been studied through the use of gamma-ray and sample logs; by radiometric, chemical petrographic, and spectrographic analyses of the precipitates and drill samples; and through the use of chemical analyses of brines collected from oil wells in the areas of high radioactivity.

Report discussing an experiment in which the abnormal radioactivity of radium-bearing precipitates derived from oil-well fluids taken from more than 60 oil and gas fields in Cowley, Butler, Marion, Sedgwick, and Greenwood Counties of southeastern Kansas were studied.

From abstract: The Merry Widow claim is near the center of sec. 22, T. 20 S., R, 15 W, New Mexico principal meridian, about 1 mile west of White Signal, Grant County, N. Mex. Secondary uranium minerals were discovered in the White Signal district in the early 1920's although several mines in the district had been worked previously for gold, silver, and copper. The writers mapped the Merry Widow claim in 1950, collected 133 samples, and logged the core from one diamond-drill hole on the Merry Widow claim.

Abstract: "Comparative data are presented on separations of microgram amounts of uranium from milligram amounts of various metal ions with Na2Co3-K2CO3, Na2CO3-K2CO3-H2O2, and Na2CO3-NaClO. The Na2CO3-K2CO3 separation procedure is applied to the analysis of shales, lignites, and monazites. This method will determine as little as 0.001 percent uranium in shales and lignites and 0.01 percent uranium in monazites."

Report discussing a geological examination of numbered federal and state highways and unnumbered roads in Massachusetts during the 1948 and 1949 field seasons to find radioactive rocks.

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.

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.

From abstract: "This report summarizes our knowledge of the geology of radioactive raw materials and outlines the work done by the Geological Survey as well as that planned or recommended. An evaluation of uranium and thorium deposits is given in terms of known reserves and potential resources."

Report discussing a 1948 geological examination of 7,662 miles of roadside rocks in Vermont, Connecticut, Rhode Island, and southeastern New York to find deposits of radioactive materials.

From abstract: In 1948, 7,662 miles of roadside rocks and soils in Vermont, New Hampshire, Connecticut, Rhode Island, and southeastern New York were traversed with a car-mounted Geiger-Mueller counter. The observed distribution of the abnormally radioactive rocks and soils is limited to certain areas, herein called "radioactive provinces," that are separated from each other by areas of essentially nonradioactive rock.

Report discussing the U.S. Geological Survey's measurement of radioactivity of rocks along 4,600 miles of road in Maine.

A report regarding study data related to radioactive rocks in Maine and various sampling to determine types and grades of rocks in the area.

Report discussing the identification of hydrothermal uranothorite from fluorite breccias in Colorado and its comparison/contrasting with other uranothorites and thorites. A description of thorium halos in fluorite is given.

Report discussing the U.S. Geological Survey's investigation aimed at finding a location with an abundance of black shale, and determining the amount of uranium in the shale.

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.

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.
