Water in the deep Earth

点击翻译按钮获取中文摘要

Water has profound influence on many deep Earth processes ranging from melting to plate movements. Water in deep Earth is replenished by subduction. A significant part of water can be stored in nominally anhydrous minerals, such as olivine, pyroxene and garnet that result from the breakdown of hydrous phases within the subducted lithosphere. The project proposes a combined experimental and analytical project to determine how much water is transported to the deeper mantle in these minerals. This project aims to determine the incorporation mechanisms of water into these key minerals and to establish an Australian facility for water determination in minerals that has the sensitivity needed for studying deep Earth materials.
