云开隆起区经历了自晋宁期以来的多次塑性一半塑性再造和脆性改造,在其边缘和内部发育了一系列其不同流变学性质了剪切带,构成了有规律的剪切带阵列.按剪切带的时空分布特点及流变学属性等,概略划分为韧性剪切带阵列和脆性剪切带阵列,并分别由边缘剪切带系统和内部剪切带系统所组成。较详细地叙述了各剪切带阵列和系统的几何学、运动学及流变学特征、探讨了剪切带阵列与金矿成矿关系,并结合成矿动力学背景分析,指出云开隆起区的金矿成矿有利地段是其边缘,尤其位北缘和西缘。
The Yunkai uplifted area has undergone several plastic half-plastic rebuilding and brittle transformation since the Jinning Period. A series of shear bands with different rheological properties have been developed at the edge and inside, forming a regular shear band Array. According to the spatio-temporal distribution characteristics and rheological properties of the shear zone, it is roughly divided into a ductile shear zone array and a brittle shear zone array, which are respectively composed of an edge shear zone system and an internal shear zone system. The geometrical, kinematic and rheological characteristics of each array and system of shear bands are described in detail. The relationship between the shear band array and gold mineralization is discussed. Combined with the background analysis of metallogenic dynamics, it is pointed out that the clouds open up Gold deposits in the area is favorable for the edge of the area, especially the northern and western margins.
