This project is a one-year study focused on clarifying the field, age, spatial, and genetic relationship of normal and strongly- contaminated and reduced peraluminous granite plutons with specific pre-batholith wall rocks of the Caucasus. Biotite mineral and whole rock chemistry will be used to characterize the redox state and halogen contents of magmatic and hydrothermal fluids. Four weeks of field work in the U.S.S.R. is required for five north-south transects crossing the Caucasus, ahd the research will be done in collaboration with three Soviet geologists. A return visit for them to the U.S. will provide an opportunity for them to engage in research of magma/wall interaction.

本项目是一项为期一年的研究，重点是澄清高加索地区正常、强污染和还原过铝花岗岩岩体与特定的前岩基围岩的领域、年龄、空间和成因关系。黑云母矿物和全岩化学将用于描述岩浆和热液的氧化还原状态和卤素含量。穿越高加索的五条南北横断面需要在苏联进行为期四周的实地工作，研究工作将与三名苏联地质学家合作完成。如果他们回访美国，将有机会从事岩浆/岩壁相互作用的研究。
