摘　　要：马元铅锌矿床位于扬子板块北缘,矿床赋存于震旦系灯影组白云岩中,受断裂和地层控制明显,围岩蚀变较弱以碳酸盐化为主。本文通过对矿床的矿体特征、矿物组合矿石结构构造等基础地质特征研究及矿床地球化学研究,总结了矿床主要控矿因素,最终确定矿床为MVT型铅锌矿床。Mayuan Pb-Zn deposit is located in the northern part of Yangtze Platform.The deposit mainly occurs in the dolomite of the Zhendan Dengying Formation,and is obviously controlled by faults and strata.The main alteration of wall rock is carbonation.This paper studies on the basic characteristics of the ore body,mineral assemblage,ore structure and geochemistry of the deposit,and summarizes the main ore-controlling factors of the deposit.The deposit is finally determined as MVT type Pb-Zn deposit.
