Acquisition of Extraction Lines for Carbon, Oxygen,Hydrogen,and Sulfur Isotopic Analyses of Minerals

该奖项为建设真空提取生产线提供了两年的支持，用于硅酸盐、碳酸盐和硫化物矿物中氧、碳、硫和氢的稳定同位素分析。开采管线将在南加州大学地质科学系首席调查员的监督下建造。通过使用提取管线，利用稳定的同位素数据的广泛研究项目将成为可能。首席研究员的主要研究重点将是流体在变质过程中的作用。将对加利福尼亚州东南部的惠普尔山变质核杂岩进行详细的氧、氢和碳同位素研究，以评估流体在重要的地壳过程中的作用，如拆离断层作用、糜棱岩化、热传递和花岗岩熔体的形成。

This award provides two years of support to construct vacuum extraction lines for stable isotope analysis of oxygen, carbon, sulfur and hydrogen in silicate, carbonate and sulfide minerals. The extraction lines will be constructed under the supervision of the Principal Investigator in the Department of Geological Sciences at the University of Southern California. A broad range of research projects utilizing stable isotopic data will be made possible with the use of the extraction lines. The main focus of the Principal Investigator's research will the role of fluids in metamorphic processes. A detailed oxygen, hydrogen and carbon isotope study of the Whipple Mountain metamorphic core complex in southeastern California will be undertaken to evaluate the role of fluids in important crustal processes such as detachment faulting, mylonitization, heat transfer, and granitic melt generation.
