兴义市雄武背斜南东翼多金属矿成矿控制

Metallogenic Control of Polymetallic Minerals in the Southeastern Wing of Xiongwu Anticline, Xingyi City

通过对雄武背斜多金属成矿地质背景分析,总结以往找矿成果,根据蚀变和矿化情况,划分三个矿化带。根据矿化特征,鉴别导矿构造和容矿构造。认为雄武断裂束和七舍断裂束是控矿构造,主要起导矿作用。其次级断层既是导矿构造,也可以是容矿构造。阳新组顶部古喀斯特面、下三叠统中的层间破碎带是容矿构造。后两者的叠加部位是重要的成矿空间。在此基础上对成矿模式进行了初步探讨。

Based on the analysis of the geological background of the multi-metal mineralization of the Xiongwu anticline,the previous ore-finding results were summarized and three mineralized zones were divided.It is believed that the Xiongwu fault bundle and the Qishe fault bundle are ore-controlling structures,which mainly play a role in guiding ore.The secondorder fault is both a ore-conducting structure and a ore-bearing structure.The interbedded fracture zone in the top of the ancient karst and lower Triassic of the Yangxin Formation is the ore-bearing structure.The superposition of the latter two is an important mineralization space.Based on this,a preliminary discussion on the metallogenic model was carried out.
