The principal investigators will study high-grade metamorphic rocks in the People's Republic of China in collaboration with scientists from the University of California at Santa Barbara, the Academia Sinica of Peking University and the Provincial Bureau of Geology and Mineral Resources from Hubei and Anhui. The objectives are to map several metamorphic belts in central China, to thoroughly study the mineralogy of the high-pressure rocks there, to delineate mineral parageneses and the pressure-temperature-time paths of the rocks, to establish geologic ages for the several critical rock units, and to relate these to igneous and tectonic features. The study will lead to a better understanding of how continental crust was subducted to mantle depths, and later exhumed.

主要研究人员将研究高级变质岩 在中华人民共和国与科学家合作 来自加州大学圣巴巴拉分校 北京大学中国地质大学与省地质局 以及湖北和安徽的矿产资源。其目标是 绘制了华中地区几条变质带的分布图， 高压岩石的矿物学， 矿物共生和压力-温度-时间路径 岩石，以确定几个关键岩石的地质年龄 单位，并将这些与火成岩和构造特征。的 这项研究将有助于更好地了解大陆地壳是如何 被俯冲到地幔深处，后来又被挖出。
