Lithostratigraphic Controls on Granites and Related Ore Deposits of Caucasus and Mongolia

该项目是一项为期一年的研究，重点是澄清正常、强污染和还原过铝花岗岩的野外、年龄、空间和成因关系，以及高加索地区特定的前岩基围岩。将利用黑云母矿物和全岩化学来表征岩浆和热液的氧化还原状态和卤素含量。横跨高加索的五个南北断面需要在苏联进行为期四周的野外工作，这项研究将与三名苏联地质学家合作完成。他们对美国的回访将为他们提供一个从事岩浆/墙相互作用研究的机会。

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.
