Collaborative Research: Geochemical and Petrologic Study of Fluid/Rock Interaction in the Low-Pressure Metamorphic Terrain in Wildrose Canyon, California

首席研究员将与田纳西大学的西奥多·拉博特卡（Theodore Labotka）合作，研究加州帕纳明山脉的威尔德罗斯峡谷地区160 Ma的区域性变质钙质泥质岩。研究流体对经历过低压区域进、逆变质作用的岩石的地球化学和矿物的影响。使用的主要方法包括岩石学工作（以及相平衡分析）、稳定同位素测量和总主元素质量平衡计算。该研究将增强我们对中地壳深处区域变质作用和流体-岩石相互作用的认识。

The principal investigator, in collaboration with Theodore Labotka of the University of Tennessee, will study the 160 Ma regionally metamorphosed calcareous argillites in the Wildrose Canyon area of the Panamint Mountains, California. The purpose of the work will be to understand the effects of fluids on the geochemistry and minerals of rocks which have undergone low- pressure regional prograde and retrograde metamorphism. Principal methods to be utilized include petrographic work (and in turn phase equilibria analyses), stable isotope measurements, and total major-element mass balance calculations. The study will enhance our understanding of regional metamorphism and fluid-rock interactions at mid-crustal depths.
