The Systematics of B and Be in Subduction Zone Sediments

这个项目将研究海洋沉积物中Be和B的分布过程。一旦了解了这些元素的行为，它们就有可能成为岩浆生成过程中含水流体的敏感示踪剂，在研究岛弧岩浆的起源方面尤其有用。该项目将量化各种海洋沉积物岩性孔隙水和沉积物中元素及其同位素的出现，并在高压和高温下对标记样品进行实验，以确定这些元素在热液系统中的行为。

This project will study the processes governing the distribution of Be and B in marine sediments. Once the behavior of these elements is understood, they have the potential to serve as sensitive tracers of aqueous fluids in magma generation, and will be especially useful in studying the origin of island arc magmas. This project will quantify the occurrence of the elements and their isotopes in porewaters and sediments from a wide range of marine sediment lithologies and perform an experiment with labelled samples at high pressure and temperature, in order to determine how the elements behave in hydrothermal systems.
