From objective and scope: The objective of this report us to provide a descriptive body of knowledge on Cordilleran metamorphic core complexes including their lithologic and structural characteristics, distribution within the Cordillera, and their evolutionary history and tectonic setting. We also examine the occurrence of uranium in the context of possibility for uranium concentration.

From abstract: This geologic study of Kettle dome, northeast Washington, encompasses an area of approximately 800 square miles (2048 sq km). The evaluation of uranium occurrences associated with the igneous and metamorphic rocks of the dome and the determination of the relationship between uranium mineralization and stratigraphic, structural, and metamorphic features of the dome are the principal objectives. Evaluation of the validity of a gneiss dome model is a specific objective. The principal sources of data are detailed geologic mapping, surface radiometric surveys, and chemical analyses of rock samples.

From abstract: "A literature study was conducted on the geology of the Southern Piedmont province of the states of Maryland, Virginia, North Carolina, South Carolina, and Georgia. The purpose was to identify geologic areas potentially suitable for containment of a repository for the long-term isolation of solidified radioactive waste."

This report is an issue of the original draft copy of the "Interim Staff Report on Uranium Exploration on the Colorado Plateau", dated June 1951. The original draft copy was only recently located and is being published at this time because of the interest in the contained historical content.

From summary: In this first annual report for subcontract BFEC 79-384-E (Uranium in Granites of Southwestern North America) we have established the general geological and geochemical background for our investigations. We describe the regional setting and some important geochemical patterns, constituting a major uranium anomaly, of the Precambrian basement in the Colorado Plateau region. Three of our investigated samples were derived from a portion of this region in central and northern Arizona. We describe the tectonic and petrologic setting for a fourth sample, a granite from the young (Cretaceous) Peninsular Ranges Batholith of southern California.

From introduction: Our particular interest in the uranium potential of the Proterozoic quartz-pebble and quartzite-pebble conglomerates of the Kingston Peak Formation has been based upon: 1. Known uranium occurrences of low to intermediate grade in a peliticarkosic sulfide-bearing unit near the base of the formation; the "Favorable Submember" of this report. 2. Uranium occurrences and widespread anomalies in underlying Proterozoic granitic-metamorphic rocks, including the World Beater Complex, within and bordering the basin in which the conglomerates were deposited. 3. Reported minor shows of uranium associated with extensive anomalous radioactivity in the conglomerates themselves.

From abstract: This abbreviated data report presents results of ground water and stream/surface sediment reconnaissance in the National Topographic Map Series (NTMS) Mesa 1 x 2 quadrangle. Surface sediment samples were collected at 713 sites, at a target sampling density of one site per 13 square kilometers (five square miles). Ground water samples were collected at 365 sites. Neutron activation analysis (NAA) results are given for uranium and 16 other elements in sediments, and for uranium and 9 other elements in ground water. Mass spectrometry results are given for helium in ground water. Field measurements and observations are reported for each site. Analytical data and field measurements are presented in tables and maps.

Supplementary data including elemental concentration data in surface sediment samples, site location data, and a user's guide to accompany a report on hydrogeochemical and stream sediment reconnaissance.
