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.

该奖项提供一半所需资金，用于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实验室的运营。 大学致力于提供所需的剩余资金。 南加州大学稳定同位素实验室主要从事研究水性流体在地壳地质过程中的作用的研究项目。当前项目的具体目标包括： (1) 确定地表（大气）水渗透地壳的深度。 (2)穿过岩石静压-静水压过渡带的流体-岩石相互作用的性质。 (3)流体在断层和剪切带中的作用。 (4) 了解地壳内冷却岩浆岩体逸出流体的影响。这些总体目标是通过对加利福尼亚州和亚利桑那州莫哈韦沙漠岩石中同位素变化（主要是氧、碳、氢和硫）的详细研究来调查的。
