This project will conduct an isotopic tracer study of the Macquarie Island ophiolite to establish isotopic profiles through continuous sections of ocean basement in order to quantify isotopic exchange etween seawater and ocean crust, to understand controls on hydrothermal fluid compositions to trace water-rock interactions, and to study the metamorphic petrology of the plutonic section of the Macquarie ophiolite.

该项目将对麦夸里岛蛇绿岩进行同位素示踪研究，通过洋底连续剖面建立同位素剖面，以量化海水和洋壳之间的同位素交换，了解对热液成分的控制以追踪水-岩石相互作用，并研究麦夸里岛蛇绿岩深成部分的变质岩石学。
