Design of a Groundwater Sampling Network for Minnesota

Description: From introduction: This folio was compiled to facilitate the use of groundwater as a sampling medium to aid in exploration for hitherto undiscovered deposits of uranium in the subsurface rocks of Minnesota. The report consists of the following sheets of the hydrogeologic map of Minnesota: 1) map of bedrock hydrogeology, 2) generalized cross sections of the hydrogeologic map of Minnesota, showing both Quaternary deposits and bedrock, 3) map of waterwells that penetrate Precambrian rocks in Minnesota. A list of these wells, showing locations, names of owners, type of Precambrian aquifers penetrated, lithologic material of the aquifers, and well depths is provided in the appendix to this report.

Aerial Gamma Ray and Magnetic Survey, Raton Basin Project, The Shiprock & Gallup Quadrangles of Arizona/New Mexico and Albuquerque Quadrangle, New Mexico: Final Report, Volume 1

Description: From introduction: This final report .is organized in two logical sections: (a) Volume I, containing the survey description, specifications, data processing methods, interpretation methods, regional geologic review and regional survey results and (b) one volume, Volume II, for each of the three quadrangles covered by the Raton Basin Project Area. Each Volume II contains a detailed geologic summary, interpretation report, standard deviation maps, pseudo-contour maps, interpretation map, flight line and geologic base map, individual corrected profiles, computer map unit histograms and statistical tables.

NURE Aerial Gamma-Ray and Magnetic Reconnaissance Survey, Colorado [i.e. California]-Arizona Area, Salton Sea NI 11-9, Phoenix NI 12- 7, El Centro NI 11-12, Ajo NI 12-10, Lukeville NH 12-1 Quadrangles: Volume 1 - Narrative Report

Description: From abstract" As part of the Department of Energy (DoE) National Uranium Resource Evaluation Program, LKB Resources, Inc. has performed a rotary-wing reconnaissance high sensitivity radiometric and magnetic survey, encompassing several 1:250,000 quadrangles in southwestern Arizona and southeastern California. The surveyed area consisted of approximately 9300 line miles. The radiometric data was corrected and normalized to 400 feet terrain clearance. The data was identified as to rock type by correlating the data samples with existing geologic maps. Statistics defining the mean and standard deviation of each rock type are presented as listings in Volume I of this report. The departure of the data from its corresponding mean rock type is computed in terms of standard deviation units and is presented graphically as anomally maps in' Volume II and as computer listings in microfiche form in Volume I.

A Modeling Study of Gaseous Rn-222, Xe-133, and He-4 for Uranium Exploration

Description: From introduction: The emanation method of uranium exploration consists of measuring the abundance of one or more uranium decay products at some distance from the orebody itself. The halo of decay products expands the exploration target and improves the chances of detection. This method assumes that indicator nuclides migrate away from the ore by some physio-chemical mechanism such as diffusion or solution in groundwater. The indicators must remain at detectable concentrations and be distinguishable from background levels. This study is concerned with gas-phase transport of Rn-222, Xe-133, and He-4 away from uranium ore deposits. The first of these indicator nuclides, Rn-222, is a member of the uranium series decay chain (Table 1) and has a 3.82 day half-life. The second, Xe-133,. is a spontaneous fission product which has a half-life of 5.26 days. Finally, He-4 is a stable nuclide created from alpha particles emitted by various members of the uranium, actinium, and thorium decay series.

Preliminary Report on the Uranium Favorability of the Hartselle Sandstone and the Pottsville Formation in the Coosa Basin, Alabama

Description: From summary: The Hartselle Sandstone and the Pottsville Formation in the Coosa basin were studied to determine if the units appear favorable for the occurrence of uranium deposits and if a more detailed investigation of the area is warranted. The study involves a literature synthesis, field work, and sampling of rock outcrops for petrographic and chemical analyses.

Aerial Gamma Ray and Magnetic Survey, Powder River 2 Project, the Torrington Quadrangle of Wyoming/Nebraska and Casper Quadrangle, Wyoming: Final Report, Volume 1

Description: From abstract: From September 15 to September 28, 1978, geoMetrics, Inc., collected 4320 line miles of high sensitivity airborne radiometric and magnetic data in Wyoming and Nebraska within two 1° x 2° NTMS quadrangles (Torrington and Casper).

[DOPTAP Output Listings for National Topographic Map Section NI 13-6]

Description: DOPTAP computer output files for all profile data for the map lines and tie lines surveyed in a report to give the basic uranium, thorium and potassium equivalent gamma radiation intensities, ratios of these intensities, aircraft altitude above the earth's surface, total gamma ray and earth's magnetic field intensity, correlated as a function of geologic units indicated from available geologic maps. Results of analyses of these field data are presented as profile plots of the gamma radiation and earth's magnetic field.
