Figure 10. Relation between (A) strontium isotopic compositions (87Sr/86Sr) and reciprocal strontium concentrations for acid leachates of borehole samples and (B) 87Sr/86Sr and silicon dioxide (SiO2) concentrations for acid leachates of borehole samples, Nevada Test Site, Nye County, Nevada. Error bars represent 2-sigma analytical uncertainty and are shown as 10 percent of the reported concentration value for strontium and 15 percent for SiO2.
