| 英文摘要 | Springs and seeps in the Tecopa basin were sampled and analyzed for their major ion chemistry and oxygen, hydrogen, and boron isotope compositions in order to assess the possible origins of the waters. The Tecopa basin is a groundwater discharge area along the Amargosa River drainage basin south of the Nevada Test Site and proposed high-level nuclear waste repository at Yucca Mountain, NV. The spring waters are categorized into three end-member hydrochemical facies: (1) pH-neutral, Na + Ca + Mg + SO4 + HCO3 water with moderate to high total-dissolved solids;, (2) mildly alkaline, Na + Cl + SO4 + HCO3 water with high total dissolved solids; and (3) alkaline, Na + HCO3 + CO3 water with high total dissolved solids. The temperatures of most of the springs range from 17 degreesC to 32 degreesC; however, waters in the Tecopa Hot Spring area range from 9 degreesC to 47 degreesC. The oxygen and hydrogen isotope compositions (normalized to SMOW) of the waters are as follows. The facies 1 springs have a mean delta O-18 of - 12.77 +/- 0.14%o (1 sigma) and delta D of - 94.9 +/- 0.5%(o) (1 sigma). The facies 2 springs have a mean delta O-18 of - 12.73 +/- 0.19%o (1 sigma) and delta D of - 97.7 +/- 0.9%o (1 sigma). The facies 3 spring has a mean delta O-18 of - 13.09 +/- 0.17%o (1 sigma) and delta D of - 103.5 +/- 0.7%o (1 sigma). The mean boron concentrations and isotope compositions range from 2.4 mg/l and delta (11) B of + 2.5%o for facies I springs to 72.8 mg/l and delta (11) B of - 3.8%o for the facies 3 spring. |
