摘    要:五龙金矿位于丹东北东向韧性剪切带中,是一个典型的后韧性剪切带型金矿,韧性剪切带由应变不均一的线性强应变带和透镜状弱应变域构成,总体呈现网结状构造样式,韧性剪切变形的强弱与围岩中金元素的运移富集程度密切相关,其强、弱应变域直接控制含金石英脉的空间分布,根据剪切带构造演化与成矿过程在时空上的联系,建立了该区的构造控矿模式。

关 键 词:韧性剪切带  网结状构造样式  糜棱岩  构造控矿模式

Abstract:Wulong gold deposit situated in NE-trending ductile shear zone is a typical one of post-ductile shear zone. The ductile shear zone is composed of inhomogeneous strong-linear-strain zone and weak-lensoid-strain domain, which is characterized by network-structural pattern. Deformational intensity of ductile shear zone is closely related to degree of transport-concentration of gold in country rock , strong and weak strain domains directly control spatial distribution of bearing-gold quartz vein. According to the relationship between tectonic evolution of shear zone and mineralizing process in time and space , tectonic-controlled model has been established in this region.
Keywords:ductile shear zone  network-structural pattern  mylonite  tectonic-controlled model
