Figure 8. Relation between (A) strontium (Sr) and zirconium (Zr) concentrations, (B) strontium and rubidium (Rb) concentrations, (C) zirconium and rubidium concentrations for bulk-rock outcrop samples, and (D) the frequency distribution of strontium concentrations for bulk-rock outcrop samples with zirconium concentrations less than or equal to 20 micrograms per gram, Nevada Test Site and adjacent areas, Clark, Lincoln, and Nye Counties, Nevada, and Inyo County, California. Error bars represent 2-sigma analytical uncertainty and are shown as 10 percent of the reported concentration value.
