Microanalysis of Stable Isotope Ratios in Metamorphic Rocks

这个正在进行的项目将继续开发和应用稳定同位素比率微量分析的新技术。研究将利用激光探针、离子探针和常规技术研究高品位变质岩的微米尺度分带。该项目的主要目标是记录变质岩中同位素分带的样式，并阐明这种非均质性的原因。该研究将最终应用于地壳流体迁移理论、麻粒岩成因、地温学和冷却/隆升史的评价。

This ongoing project will continue development and application of new techniques for the microanalysis of stable isotope ratios. The studies will utilize the laser probe, ion microprobe and conventional techniques to study micron-scale zoning in high grade metamorphic rocks. The principal goals of the project are to document the styles of isotopic zonation in metamorphic rocks and to elucidate the causes of such heterogeneity. This research will ultimately find application in evaluating theories of fluid migration in the crust, granulite genesis, geothermometry, and cooling/uplift history.
