Trace Element Mobility During Hydrothermal Alteration in the Oceanic Crust

该项目将开发一种新的观测方法来研究海洋热液系统中的水-岩相互作用。其目标是利用伍兹霍尔海洋研究所的离子微探测器，在微米尺度上确定热液蚀变岩石中的微量元素分布。原生/次生矿物对和脉状矿物的数据将有助于评估具体的变质反应如何影响热液流体的组成和洋壳的蚀变。

This project will develop a new observational approach to investigate water-rock interaction in oceanic hydrothermal systems. The goal is to determine the distribution of trace elements in hydrothermally altered rocks on a micron scale using the ion microprobe at Woods Hole Oceanographic Institution. Data for primary/secondary mineral pairs and vein minerals will allow the evaluation of how specific metamorphic reactions influence the composition of hydrothermal fluids and altered oceanic crust.
