The principal investigator will study the origin and movement of fluids which have interacted with high-grade metamorphic terrances in the East Humboldt Range, Nevada, utilizing field, petrologic, and isotopic techniques. He will attempt to constrain relationships between porosity, flux, and time, and will use isotopic information to assess relative porosities, and to establish a qualititative and quantitative scale of effective permeability in crustal lithologies. Results will help geologists understand the role of fluids during the metamorphism of rocks in the Earth's crust.

首席研究员将研究 与高级变质碎屑相互作用的流体 在东洪堡山脉，内华达州，利用现场，岩石学， 和同位素技术。他会试图限制关系 孔隙度、通量和时间之间的关系，并将使用同位素信息 以评估相对孔隙度，并建立一个定性和 地壳有效渗透率定量标度 岩性研究结果将有助于地质学家了解 地壳岩石变质过程中的流体。
