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.

From abstract: The Bulloch group of uranium claims are in T. 40 S., R. 9 we, Kane County, Utah. The past production has been 8.5 tons of submarginal ore submitted to the Marysvale purchasing depot of the Atomic Energy Commission in 1950; this shipment assayed 0.16 percent U308, Uranium is finely disseminated in clay, carbonaceous clay, carbonized wood fragments, iron-oxide concretions, petrified logs, sandstone, and conglomerates of the lower part of"the Dakota sandstone and upper part of the Summerville formation. Small quantities of carnotite, autunite, and torbernite are exposed in the conglomerate and sandstone on Lynn Nos. 2 and 3 claims.

Report issued by the Bureau of Mines over magnetometer surveys conducted on iron deposits in Utah. Details of the deposits included in the survey are listed. The methods of testing each deposit are also presented. This report includes tables, maps, photographs, and illustrations.

From to the files: The Shinarump-Moenkopi contact on Oljetoh Mesa in the Monument Valley district, Arizona-Utah, was examined from November 5 to 15, 1951, to determine the location of and the mineralization in Shinarump channels. Twenty-seven distinct channel outcrops were located and examined. Three of these channel outcrops are mineralized and the remaining 24 are barren. Plate I shows the distribution of the Shinarump, the Moenkopi, and the DeChelly member of the Cutler formation; the location of the Shinarmp channel outcrops; the channel trend where there is good evidence for such a trend. The Hoskinrnini tongue of the Cutler was mapped with the Moenkopi as it is not a good mappable unit in this area. The three mineralized outcrops are indicated by the letters A, G, and AA while the barren outcrops bear the letters B to F and H to Z.

A method for determining the background geothermal gradient values through the analysis of temperature measurements at multiple depths to 3 m and recorded over a time span of several days is presented. The analysis is based on the amplitude decay and phase shift of temperature waves with depth. Diurnal and other high frequency temperature variations are used to compute thermal diffusivities which in turn are used to model and remove the effect of the annual temperature wave. The analysis considers both a homogeneous half space and a two layer medium consisting of an overburden of finite thickness overlying a semi-infinite substratum. The method was tested in three holes in the Crystal Hot Springs geothermal field. Temperatures in each hole were recorded once a minute over a period of three days with a probe containing thermistors at eight different depths. Five of the thermistors were positioned at shallow depths (less than or equal to 0.5 m) to monitor diurnal and other high frequency waves and three at greater depths (greater than or equal to 1 m) to measure lower frequency variations. Since measurements were recorded at only three sites, the accuracy and reliability of the method is not fully evaluated. Potential …

Report discussing a preliminary study of limonite sourced from nine localities of different types through Colorado, Utah and Wyoming, in the spring and fall of 1953. This study aimed to establish criteria for differentiating uranium- and thorium-related limonite and limonite not related to uranium or thorium. The report is divided by descriptions of each locality.

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."

Report discussing investigation of the relation of uranium and phosphate in the Phosphoria formation and its close stratigraphic equivalents.

Abstract: Weak uranium mineralization is widespread throughout the Uinta Basin of northeastern Utah and northwestern Colorado, in rocks ranging in age from Permian to Eocene. No commercial ore bodies are known, although formations there have characteristics elsewhere considered favorable for ore deposition.
