摘要
黄沙坪铅锌矿床是湘南地区最大的铅锌多金属矿床,其矿化特征与矿区燕山早期侵入岩体密切相关。通过对前人资料进行分析,认为其成矿物质主要来自深部中元古代矿源层,通过深熔作用形成花岗岩浆并经过复杂的花岗岩浆演化作用,使成矿元素不断富集,最终形成富含成矿元素的岩浆热液,之后在极有利的围岩-构造-岩浆岩体侵位条件下,经历了多期次的成矿作用,完成了矿质沉淀与矿体定位。
Huangshaping deposit is the largest Lead-Zinc polymetallic deposit of southern Hunan area.The mineralization are closely link to Yanshanian intrusive rock.Through the analysis of previous data,the ore-forming material mainly comes from the deep middle Proterozoic source bed which form granitic magma by deep melting.Through the complex evolution of granite magma,the ore-forming elements are enriched continuously,and finally magmatic hydrothermal fluids rich in ore-forming elements are formed.The mineralization has undergone multiple stages with favorable emplacement conditions of the surrounding rock-magmatic rock and structural.Therefore,mineral deposited and ore body positioning have been completed.
