Reno 10 x 20 NTMS area Nevada: data report

This data report presents results of ground water and stream sediment reconnaissance in the National Topographic Map Series (NTMS) Reno 10 x 20 quadrangle. Stream sediment samples were collected from small streams at 960 sites or at a nominal density of one site per 18 square kilometers (seven square miles). Neutron activation analysis (NAA) results are given for uranium and 16 other elements in sediments, and for uranium and 10 other elements in ground water and surface 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. Statistical summaries of data and a brief description of results are given. A generalized geologic map and a summary of the geology of the area are included. Data from ground water sites (on microfiche in pocket) include (1) water chemistry measurements (pH, conductivity, and alkalinity), (2) physical measurements (water temperature, well description, and scintillometer reading), and (3) elemental analyses (U, Al, Br, Cl, Dy, F, He, Mg, Mn, Na, and V). Data from sediment sites (also on microfiche in pocket) include (1) water chemistry measurements (pH, conductivity, and alkalinity), and (2) important elemental analyses (U, Th, Hf, Al, Ce, Dy, Eu, Fe, La, Lu, Mn, Sc, Sm, Na, Ti, V, and Yb). Sample site descriptors (stream characteristics, vegetation, etc.) are also tabulated. Symbol plot maps, histograms, and cumulative frequency plots for all the elements, U/Th and U/Hf ratios, and scintillometer readings are included on the microfiche
