Technician Support for the Stable Isotope Laboratory at the University of Southern California

这项奖励提供了支持一名实验室技术员协助南加州大学地质科学系稳定同位素质谱学实验室运作所需资金的一半。该大学承诺提供所需的剩余资金。南加州大学的稳定同位素实验室主要从事研究流体在地壳地质过程中的作用的研究项目。目前项目的具体目标包括：(1)确定地表(大气)水穿透地壳的深度。(2)静岩-静水过渡带流体-岩石相互作用的性质。(3)流体在断裂剪切带中的作用。(4)了解地壳内冷却岩浆流出的流体的影响。这些总体目标是通过详细研究加利福尼亚州和亚利桑那州莫哈韦沙漠岩石中的同位素变化(主要是氧、碳、氢和硫)来实现的。

This award provides one-half of the funding required for the support of a laboratory technician to assist in the operations of the stable isotope mass spectrometry laboratory in the Department of Geological Sciences at the University of Southern California. The University is committed to providing the remaining funding required. The stable isotope laboratory at USC is primarily engaged in research projects investigating the role of aqueous fluids in geological processes of the Earth's crust. Specific goals of current projects include: (1) To determine the depth to which surface (meteoric) water penetrates the crust. (2) The nature of fluid-rock interactions across the lithostatic-hydrostatic transition zone. (3) The role of fluids in faulting and shear zones. (4) Understanding the influence of fluids escaping from cooling magmatic plutons within the crust. These general goals are investigated through detailed study of isotope variations (primarily oxygen, carbon, hydrogen, and sulfur) in rocks of the Mojave desert of California and Arizona.
