韧性剪切带变形变质作用与金的矿化富集

韧性剪切带对金矿的控制作用已引起人们广泛的关注，特别是韧性剪切带内岩石的变形变质作用在含金流体的运移，金的沉淀富集中所起的作用，本文简要回顾了韧性剪切带对金矿田（床），金矿体的控制作用，金在韧性剪切带内的沉淀富集机理，在总结前人韧性剪切成岩成矿的模拟实验研究的基础上，从变形变质作用入手，探讨了韧性剪切带内的构造物理化学过程及其与金矿化富集的关系，认为，流体作用下韧性剪切带内的变形变质作用控制着金的沉淀富集。

Deformation-metamorphism and gold mineralization in ductile s hear zone

Since people found gold mineralization related to ductile shear zone, the studies on ductile shear zone become a major topic for structure geologists and economic geology scholars.Most interest is gold mineralization controlled by ductile shear zone, especially, the role of deformation-metamorphism in the fluid flow of gold-bearing fluid and the precipitation of gold in the ductile shear zone. The paper reviews the controlling of the ductile shear zone to gold deposit and gold ore body, the principle of gold precipitation in the ductile shear zone, based on studies about the stimulating diagenetic and ore-forming hydrothermal system of the ductile shear zone. From a primary discussion of the process of tectono-physicochemistry in the ductile shear zone and its relationship between deformation-metamorphism and gold mineralization,the paper concludes that deformation-metamorphism controlled the mineralization of gold in the ductile shear zone under fluid flow.
