通过对矿区构造变形特征的分析,将本区构造变形划分为海西、印支、燕山、喜马拉雅四个变形期,相应的变形表现为顺层的剪切褶皱、韧脆性层间滑动构造、脆性断裂与节理、推覆走滑构造。海西期喷流—沉积型铜矿床形成的构造背景为金沙江弧后裂陷盆地环境,印支期及其以后叠加控矿作用表现在平面上为“入”字型构造控矿,剖面上为多层层间滑动构造控矿。
Based on the analysis of tectonic deformation characteristics in the mining area, the tectonic deformation in this area is divided into four deformation periods of Hercynian, Indo-China, Yanshan and Himalayas. The corresponding deformations are shear fold along bedding, ductile-brittle interlaminar sliding structure, brittleness Fractures and joints, thrust-strike slip structures. The tectonic setting of the Hercynian jet-sedimentary copper deposit is the environment of the Jinshajiang back-arc rift basin. During the Indosinian and later stratigraphic superposition, the ore-controlling effect was “in” On the multi-layer sliding structure control ore.
