Table 5. Oxide and elemental concentrations and strontium isotopic compositions (87Sr/86Sr) of nitric-acid leachates of core samples from boreholes at the Nevada Test Site, Nye County, Nevada.
[Results are for samples collected and analyzed in 2006. Oxide concentrations are given in weight percentages, and elemental concentrations are given in micrograms per gram. The less than (<) symbol is used to indicate concentrations that are below minimum reporting limits and incorporate the measured dilution factors for each sample; the greater than (>) symbol is used to indicate concentrations that are above the range of standards used to define the calibration curve. Uncertainties for strontium isotopic compositions (87Sr/86Sr) are dominated by external errors for replicate analyses of the Sr isotope standard EN-1, therefore, a blanket 87Sr/86Sr uncertainty of 0.00005 is reported. Strontium isotopic compositions also are given in delta notation (δ87Sr = [(87Sr/86Srsample/87Sr/86Srmsw)-1] ×1,000 and δ87Srt = [(87Sr/86Srsample/87Sr/86Srpsw)-1]×1,000, where 87Sr/86Srmsw is the value for modern seawater and 87Sr/86Srpsw is the value for paleoseawater at the time of deposition). Abbreviations: MgO, magnesium oxide; CaO, calcium oxide; CaCO3, calcium carbonate (calcite); SiO2, silicon dioxide; Al2O3, aluminum oxide; MnO, manganese oxide; Rb, rubidium; Sr, strontium; Th, thorium; U, uranium; ‰, permil]
