俯冲带的流体地质作用

FLUIDS IN SUBDUCTION ZONES

俯冲带是地球上流体活动最活跃的地区之一，也是流体由表层进入深部岩石圈的主要通道。流体活动对岩石成分、成岩作用、构造变形、变质作用、部分熔融和岩浆－火山作用，以及海洋生物－化学环境都有重要的控制和影响。本文回顾和总结了俯冲带流体地质作用研究的现状和进展，对古俯冲带流体地质作用的若干问题进行了探讨。

Subduction zones are one of most mobile sites to fluid fluxes and main route throughwhich fluids enter deeper depth of the lithosphere. Fluids play an important role in almost allaspects of geological processes such as petrogenesis , chemical composition and isotopic charac-teristics,deformation,metamorphism,partial melting, magmatism and volcanic activities as wellas oceanic organic-chemical environment. In this paper.fluids manifestations and influences insubduction zones are reviewed and discussion for fluid studying in ancient subduction zones are present-ed.
