摘要
根据矿床形成的地质环境、成矿作用、空间分布规律及含矿岩石的特征,确定了麻栗坡县老寨马卡锌矿属花岗岩外接触带矽卡岩型、石英脉型矿床。从矿体形态、产状及发育的两种矿床类型看,矿床成因具有明显的多源性和多期次成矿特点,且花岗岩对成矿具有主导性的控制作用。
According to analying the geological environment,mineralization,spatial distribution and the characteristics of ore-bearing rocks,the Laozhaimaka zinc deposit in Malipo County can be determined to belong to the skarn type and quartz vein type deposits in the outer contact zone of granite.Judging from the shape,occurrence and two types of deposits,the genesis of the deposit has obvi‐ous characteristics of multi-source and multi-stage mineralization,and granite plays a leading role in controlling mineralization.
