Metamorphism, fluid flow, anatexis and the petrogenesis of peraluminous magmas: constraints from boron and lithium elemental and isotopic geochemistry

过铝质岩浆的变质作用、流体流动、深熔作用和岩石成因：来自硼锂元素和同位素地球化学的制约。硼(B)和锂（Li）元素和同位素变化是变质作用、流体流动和熔融作用的敏感监测指标；花岗岩的生成；热液蚀变。然而，对B和Li的详细地球化学了解甚少。该项目利用野外、分析和实验技术来约束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。该研究结果将极大地增加我们对高温地壳环境中B、Li系统的认识，并对一系列变质和火成岩作用具有指导意义。

Metamorphism, fluid flow, anatexis and the petrogenesis of peraluminous magmas: constraints from boron and lithium elemental and isotopic geochemistry. 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.
