山峰岭矿区铅锌多金属矿矿床地质特征及找矿方向

    Lead-zinc ore geology characteristics and exploration direction of Shanfengling deposit in Hunan

    • 摘要: 通过研究山峰岭矿区铅锌多金属矿的地质特征和矿床特征发现,铅锌矿(化)体呈脉状、星点状、浸染状、细脉浸染状充填于硅化碎裂灰岩节理、裂隙内,矿床成因类型属中低温热液充填型硫化物铅锌矿床;找矿标志是锡矿山组碎裂灰岩、次级断裂产状急剧变化、分枝复合、叠加改造地段及硅化、金属硫化物化;寻找铅锌矿床有利部位是发育于印支期构造层灰岩内的断裂破碎带。

       

      Abstract: The geology characteristics and mineral deposit characteristics of ShanFengLing deposit in Hunan were discussed. The types of mineral deposit-forming and exploration indication were given. Lead-zinc body is vein, star shape and dip-dye filled in silicified cataclastic rock joints and fissure. The type of deposit forming is postmagmatic hydrothermal filling sulfide lead-zinc deposit. Prospecting indicator is Xikuangshan group fractured limestone, the secondary fault occurrence dramatic changes, branching and compounding, superimposed transformation lot and silicification and metal sulfides mineralization. Advantageous prospecting position is fracture zone developed in indosinian tectonic layers of limeston
