The Systematics of B and Be in Subduction Zone Sediments

该项目将研究控制海洋沉积物中Be和B分布的过程。一旦了解了这些元素的行为，它们就有可能在岩浆生成过程中作为水溶液的灵敏示踪剂，并将在研究岛弧岩浆的起源方面特别有用。该项目将量化元素及其同位素在各种海洋沉积物岩性的孔隙水和沉积物中的赋存状态，并对标有标签的样品在高压和高温下进行实验，以确定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.
