Analysis of temperature-time data from 3 m drillholes at Crystal Hot Springs, Utah

Description: 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 problems to the method resulting from inaccurate model parameters and convective heat transport are investigated.

Geology of Area Between Green and Colorado Rivers, Grand and San Juan Counties, Utah

Description: From Abstract: "The area described in this report comprises about 900 square miles of arid land lying between the Green and Colorado Rivers south of the Denver & Rio Grande Western Railroad and southwest of the Salt Valley anticline. The rocks that crop out or that have been encountered in wells drilled in the are all sedimentary and range in age from Pennsylvania ti Upper Cretaceous. Mesizoic strata are especially well represented."

Identification and Occurrence of Uranium and Vanadium Minerals From the Colorado Plateaus

Description: Abstract: "This report, designed to make available to field geologists and others information on identification and occurrence of uranium minerals of the Colorado Plateaus, contains physical properties, X-ray data, and in some instances results of chemical and spectrographic analysis of 24 uranium and 17 vanadium minerals. Also included is a table giving the optical properties of uranium minerals and a list of locations of mines from which the minerals have been identified."

The Uranium Deposit at the Yellow Canary Claims, Daggett County, Utah

Description: Report discussing the Yellow Canary claims uranium deposit on the west side of Red Creek Canyon in the northern part of the Uinta Mountains, Daggett County, Utah. "The claims have been developed by two adits, three open cuts, and several hundred feet of bulldozer trenches. No uranium ore has been produced from this deposit."

Reconnaissance During 1952 for Uranium-Bearing Carbonaceous Rocks in Parts of Colorado, Utah, Idaho, and Wyoming

Description: The following report covers a reconnaissance for uranium-bearing carbonaceous rocks that was made during the 1952 field season in 23 areas in Colorado, Utah, Idaho, and Wyoming. This report discusses uranium samples discovered withing these locations, however it was determined that none of the deposits discovered have commercial possibilities.

Reconnaissance for Uranium-Bearing Carbonaceous Rocks in Northwestern Colorado, Southwestern Wyoming, and Adjacent Parts of Utah and Idaho

Description: Abstract: During parts of July, August, and September 1951, a reconnaissance was conducted in parts of Colorado, Wyoming, Utah, and Idaho in search of new deposits of uranium-bearing carbonaceous rocks. One significant uranium occurrence was found, the Fall Creek deposit, Bonneville County, Idaho. Several additional localities were discovered that contain uranium in concentrations many times that normally found in carbonaceous rocks.
