云南镇康县芦子园铅锌多金属矿床地质特征

THE GEOLOGICAL FEATURE OF LUZIYUAN PB-ZN MULTIMETALLIC DEPOSIT IN ZHENKANG,YUNNAN

镇康县芦子园铅锌矿为近年来新发现的超大型矿床。矿体主要赋存于上寒武统沙河厂组,矿体受北东向层间构造破碎带的控制,其成矿与矽卡岩化关系极为密切。矿床的形成主要与深部热液沿层间构造破碎带贯入并与围岩发生交代作用有关。为热液充填交代矽卡岩型铅锌矿床。

Luziyuan Pb-Zn deposit in Zhenkang is a superlarge ore deposit discovered in recent years. The ore body is mainly in Upper Cambrian Shahechang Formation. The ore body is controlled by Ne interlayer structure fracture zone. The metallogenesis is in close relation with the skarnization, mainly related to the intrusion of deep thermal fluid along the interlayer structure fracture zone and the metasomatism with the wall rock. It is a hydrothermal filling metasomatic skam Pb-Zn deposit.
