Boron (B) and lithium (Li) elemental and isotopic variations are sensitive monitors of metamorphism, fluid flow and melting; the generation of granites; and hydrothermal alteration. However, in detail B- and Li- geochemistry are poorly understood. This project uses field-based, analytical and experimental techniques to constrain B and Li elemental and stable isotope variations in order to better understand high-temperature metamorphism, fluid flow, melting and the generation of granites and pegmatites. The results of this project will greatly increase our understanding of B and Li systematics in high-temperature crustal environments, and have implications for a range of metamorphic and igneous processes.

硼（B）和锂（Li）的元素和同位素变化是变质作用、流体流动和熔融、花岗岩生成和热液蚀变的敏感监测器。然而，详细的B-和Li-地球化学知之甚少。该项目使用基于实地的分析和实验技术来限制B和Li元素和稳定同位素的变化，以便更好地了解高温变质作用、流体流动、熔融以及花岗岩和伟晶岩的生成。该项目的结果将大大增加我们对高温地壳环境中B和Li系统学的理解，并对一系列变质和火成岩过程具有意义。
