摘要
松梁铅锌矿床为川滇黔铅锌多金属成矿域内赋存于震旦系灯影组白云岩中的小型铅锌矿床,矿体产出严格受构造的控制。按其展布方向,松梁铅锌矿床的断裂构造可分为NW向、NE向、近EW向和近SN向四组,对其断裂构造解析表明:矿床构造体系划分为NWW构造带、NW构造带、EW构造带、NE构造带和NEE构造带等五种构造体系,反映本区经历了加里东期、早海西期、晚海西期、印支期、早燕山期、晚燕山期和喜山期等七期构造运动。成矿构造也分为早、中、晚三期:晚海西期、印支期和早燕山期,推测松梁铅锌矿床主矿体的成矿时代为印支期—早燕山期。
The Songliang Zn-Pb deposit occurs in Dengying Formation(Sinian) which is located in the Sichuan-Yunnan-Guizhou lead-zinc mineralization district,and is under control of fault strictly.According to the exhibition direction,the fault tectonic in the Songliang deposit can be divided into four groups,NW-trending,NEtrending,close to SN-trending,and nearly EW-trending.Tectonic analysis show that the tectonic system of Songliang deposit can be divided into NWW tectonic belt,NW tectonic belt,EW tectonic belt,NE tectonic belt and NEE tectonic belt,reflects tectonic experience Caledonian,early hercynian,late hercynian,indo-china epoch,early yanshanian,late yanshannian and himalayan.Metallogenic structure divided into three stages,corresponding late hercynian,indo-china epoch and early yanshanian.The main orebody metallogenic epoch of the Songliang Zn-Pb deposit was between indo-china epoch and early yanshanian.
