Book excerpt: This abbreviated data report presents results of surface geochemical reconnaissance in the Dan River-Danville Triassic Basin of north-central North Carolina and south-central Virginia. Unweathered rock samples were collected at 380 sites within the basin at a nominal sampling density of one site per square mile. Field measurements and observations are reported for each site; analytical data and field measurements are presented in tables and maps. A detailed four-channel spectrometric survey was conducted, and the results are presented as a series of symbol plot maps for eU, eTh, and eU/eTh. Data from rock sample sites (on microfiche in pocket) include rock type and color and elemental analyses for U, Th, Hf, Al, Ce, Dy, Eu, Fe, La, Lu, Mn, Na, Sc, Sm, Ti, V, and Yb. Elemental uranium in 362 sedimentary rock samples from the Dan River-Danville Basin ranges from a low of 0.1 to a maximum of 13.3 parts per million (ppM). The log mean uranium concentration for these same samples is 0.37 ppM, and the log standard deviation is 0.24 ppM. Elemental uranium in 10 diabase dike samples from within the basin is in the range 0.1 to 0.7 ppM. The log mean uranium concentration for diabase samples is -.65 ppM, and the log standard deviation is 0.27. This report is issued in draft form, without detailed technical and copy editing. This was done to make the report available to the public before the end of the NURE program.

Available in PDF, EPUB and Kindle. Book excerpt: The Savannah River Laboratory (SRL) is conducting a hydrogeochemical and stream sediment reconnaissance of the eastern United States as part of the National Uranium Resource Evaluation (NURE) program of the United States Department of Energy (DOE). Stream samples are collected at a density of one per 13 square kilometers in crystalline rock areas and 25 square kilometers in sedimentary rock areas. Stream sediment ( -40 mesh) is taken at each site, and stream water is concentrated on ion exchange resin in some areas. Ground water samples are collected at an average density of about one site per 20 square kilometers. Measurements made at each site include alkalinity, pH, and conductivity of water. Measurements of the radon and helium contents of ground water samples were made on a semiregional scale in pilot studies. Samples are analyzed at SRL by neutron activation techniques. Concentrations of uranium and about 20 other elements are determined in concentrated water samples. Results from several orientation studies are discussed including a Triassic Basin area near Sanford, North Carolina; the North and South Carolina Coastal Plain; and from reconnaissance studies in the Carolinas-Virginia Piedmont and Blue Ridge areas. In the Sanford Triassic Basin area, uranium content averaged 0.035 ppB in ground water from the organic-rich Cumnock formation and 1.8 ppB in the arkosic Pekin formation. Tuffaceous metavolcanics in the adjacent Carolina Slate Belt yielded water averaging about 0.1 ppB U. Studies in the Carolina Piedmont and Coastal Plain include helium, He/Ne and radon determinations in ground water. Background helium contents average about 5 ppM;anomalous samples range up to over twenty times background. During the next several years, an extensive data base will be established and published for elemental concentrations in stream sediment and surface and ground waters over much of the United States.
