The principal investigator will do fundamental analytical research on the nature of chemical zoning in metamorphic porphyroblasts, and will develop detailed models for the processes that produce both prograde and retrograde zoning. The data will be used to constrain theoretical models for garnet zoning as a kinetic monitor of metamorphic heating and cooling rates.

首席研究员将对变质卟啉母细胞的化学分带性质进行基础分析研究，并将为产生顺行和逆行分带的过程建立详细的模型。这些数据将用于约束石榴石分区的理论模型，作为变质加热和冷却速率的动力学监测。
