韧性剪切带内流体作用的研究

A Study On Fluid Action in the Ductile Shear Zone: A Review

韧性剪切带内的流体作用是一个复杂的构造物理化学过程和力学 -化学的耦合过程。它不仅影响着岩石的变形机制 ,促进变形构造的发生和发展 ,而且影响着岩石的矿物组成及化学成分的变化。本文在综合评价现有研究成果的基础上认为 ,岩石的成分变异和体积变化是韧性剪切带内流体作用研究的主要内容 ,韧性剪切带内构造 -流体演化历史、构造物理化学、岩石应变模式及其特征的研究是今后韧性剪切带内流体作用研究的发展方向和前沿领域。

The fluid action in the ductile shear zone is a complicated tectonic physochemical process coupled with the mechanic and chemical process, and is also a self_organizing process. It not only affects the deformation mechanism as well as mineral constituents and chemical components of rocks and accelerates the growth and development of deformation structure, but also controls the reactivation, migration, enrichment and precipitation of ore_forming substances of gold deposits hosted in the ductile shear zone. Based on this review, authors indicate that the readjustment of mineralogical and chemical compositions and volume changes are the main research areas of the fluid action in ductile shear zone. The study on the fluid action in ductile shear zone will be carried out in the following aspects: evolution history of tectonic_ fluid, tectonic physicochemistry, and the strain model and its features.
