科研项目及荣誉奖励

          主要从事大洋岩石圈地幔和岩浆演化过程研究,综合利用岩石学、地球化学分析手段及高温高压实验模拟技术,聚焦洋中脊的岩浆和热液系统,探讨海洋多圈层相互作用、元素物质循环以及成矿和环境效应。目前的研究包括如下:

1)洋中脊深部岩浆过程和地幔不均一性。研究全球洋脊(西南印度洋脊、东太平洋海隆、南大西洋中脊)的典型洋脊段的岩浆岩地球化学特征,揭示独特的地幔源区属性和岩浆深部过程。

2)岩石蚀变和元素循环过程。以深海构造出露的基性岩和超基性岩为研究对象,研究蚀变显微构造和关键元素的迁移和演化规律,探讨对海底热液成矿及元素循环过程的影响。

3)岩石圈地幔过程的高温高压实验模拟。主要利用活塞圆筒(Piston-Cylinder)和大腔体压机(Multi Anvil)开展大洋岩石圈地幔深度范围内的地质过程模拟研究,例如地幔熔融及岩浆结晶分异过程等。

4)水岩反应和热液成矿模拟。利用水岩反应模拟装置开展气体和流体介质与岩石的反应模拟实验研究,例如超基性岩的蛇纹石化过程和原位碳酸盐化过程,海底热液硫化物成矿过程模拟。
