通过对印江洋溪铅锌矿岩矿鉴定测试,从微观上矿区可划分为4个构造序次,各构造序次"原岩"的破坏程度、形成的结构构造、产生的矿化特征、蚀变特征均显现出不同的面貌,形成了石英→黄铁矿、闪锌矿→方铅矿、白云石→方解石的矿物生成顺序.铅锌矿为二、三构造序次析出,具有找矿指导意义.

Four structural sequences were divided by microscopic texture testing in the Yinjiang-Yangxi Pb-Zn ore deposits.The damage extents of the "initial rock", textures and structures of formation, mineralization characteristics of production, and alteration features of wall-rocks varies in each" structure succession.The minerals formation from the early to the late ore-forming stage is in order of quartz → pyrite, sphalerite → galena, cerussite → calcite.The Pb-Zn ores precipitated in the second and third structural sequence, this make a significant direction for prospecting.
