试论幔源C－H－O流体与大陆板内某些地质作用

本文主要从流体来源、组成及其运移等方面介绍了幔源Ｃ－Ｈ－Ｏ流体系统的基本特征，提出了上地幔不同深度上存在两个Ｃ－Ｈ－Ｏ流体储区的看法，即上部的富ＣＯ＿２储区及下部的富Ｈ＿２Ｏ储区。进一步分析了地幔流体的地球化学和动力学意义，初步探讨了它与大陆板块内部构造岩浆活动及有关成矿作用的可能关系。

ON THE MANTLE-DERIVED C-H-O FLUID SYSTEM AND ITS SIGNIFICANCE TO SOME GEOLOGIC PROCESSES WITHIN CONTINENTAL PLATE

The authors have mainly introduced the basic features of mantle-derived C-H-Ofluid system with respects to its origin, composition and migration. It has been proposedthat there are two kinds of C-H-O fluid reservoirs in the upper mantle,i.e.,H_2O-rich andCO_2-rich fluid reservoir.The geochemical and dynamical significance of the fluid systemand its possible effects on tectono-magmatic activities and the associated metallogeny with-in continental plate have been discussed.
