地球中流体研究的一些热点

SOME RECENT RESEARCH HOT POINTS ON FLUIDS IN THE EARTH

介绍了当前地球流体研究中的三个热点 :地幔柱 ,地壳中流体的大规模迁移和岩浆热液。地幔柱是以溢流玄武岩 ,地表的热点 ,大规模的碱性基性侵入体 ,大洋中脊的几何形状和蚀变作用来确定的。地壳中流体的大规模流动是当前研究的另一个重点 ,涉及到流体流动的尺度、速度和流体体系的持续时间以及不同地质构造单元和环境中流体的流动等方面。另一个热点是岩浆热液和成矿作用 ,涉及到研究岩浆热液的成分与Cu ,Mo和Au等矿床成矿作用的关系等。

Mantle plume,fluid migration in large scale and magmatic hydrothermal fluids are three advantage points in the research on fluids in the earth today.The mantle plume is characterized by flood basalt,hot point,large scale of alkaline\|mafic intrusions,the geometry of ocean ridges and their alteration.Recent studies have shown the evidences on long distance fluid migration within the earth's crust,and the fluid movements on different geological environments.Another progress is the magmatic fluids,and the special ore forming process in a dynamic magmatic system has been carried out.
