以金厂峪金矿床为例,研究了韧性剪切带的特征、形成环境、演化发育过程及其与金矿化的关系。韧性剪切带发育过程中的应力周期是含金流体定向迁移的驱动力,与其伴生的退变质作用则为金的活化、迁移及富集沉淀提供了必须的化学条件。韧性剪切带的发育不仅为含金流体的运移提供了通道,而且为金的富集沉淀提供了场所。
Taking Jinchangyu gold deposit as an example, the characteristics of ductile shear zone, the formation of environment, evolution and development process and its relationship with gold mineralization were studied. The stress cycle during the development of ductile shear zone is the driving force for the directional migration of gold-bearing fluids. The associated degenerate effect provides the necessary chemical conditions for the activation, migration and enrichment of gold. The development of ductile shear zone not only provides a channel for the migration of gold-bearing fluids, but also provides a place for enrichment and precipitation of gold.
