Uranium hydrogeochemical and stream sediment reconnaissance data release for the Sante Fe NTMS Quadrangle, New Mexico, including concentrations of forty-two additional elements

Totals of 982 water and 1155 sediment samples were collected from 1962 locations. Samples were collected at the nominal reconnaissnce density of one sample location per 10 km2. Water samples were collected from streams, springs, and wells and were analyzed for uranium. Sediment samples, taken from streams and springs, were analyzed for uranium, thorium, and 41 additional elements. Histograms and statistical data for uranium concentrations in water and sediment samples and thorium concentrations in sediment samples are given. Elemental concentration, field measurement, weather, geologic, and geographic data for each sample location are listed for waters and for sediments. U/Th ratios for sediment samples are included. Uranium analyses for water samples and multielement analyses for sediment samples are reported. A supplemental report containing the results of multielement analyses of water samples will be open filed in the near future. Water samples were initially analyzed for uranium by fluorometry. All water samples containing more than 40 ppB uranium were reanalyzed by DNC. Sediments were analyzed for U and Th, as well as Al, Sb, Ba, Be, Bi, Cd, Ca, Ce, Cs, Cl, Cr, Co, Cu, Dy, Eu, Au, Hf, Fe, La, Pb, Li, Lu, Mg, Mn, Ni, Nb, K, Rb, Sa, Sc, Ag, Na, Sr, Ta, Tb, Sn, Ti, W, V, Yb, and Zn. All sediments were analyzed for U by delayed neutron counting. Other elemental concentrations in sediments were determined by neutron activation analysis for 31 elements, by x-ray fluorescence for 9 elements, and by arc-source emission spectroscopy for 2 elements. Analytical results are reported as ppM. Descriptions of procedures used for analysis of water and sediments samples as well as analytical precisions and detection limits are given
