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.

首席研究人员将与加利福尼亚大学圣塔芭芭拉分校的科学家合作研究中华人民共和国的高级变质岩石，北京大学的学术界以及荷西和阿努伊的省地质和矿产局。这些目的是绘制中国中部的几个变质带，以彻底研究那里的高压岩石的矿物学，以描绘岩石的矿物质帕拉素和压力温度的时间路径，以建立几个关键岩石单元的地质年龄，并将其与小型和构造特征相关联。这项研究将使人们更好地了解大陆地壳如何俯冲到地幔深度，然后挖掘出来。
