摘　　要：赤城县梁家沟银硐山铅锌银多金属矿赋存于蓟县系雾迷山组碳酸盐岩地层中,层控特征明显。本文在野外宏观观测的基础上,对采集的岩矿石手标本及其对应的光、薄片进行了详细的分析鉴定,对其矿石矿物进行了系统的研究。根据矿物组合特征和矿物间的穿插关系,划分了成矿期次,进而认为该矿床的形成至少有两期成矿作用,即原始沉积成矿期和后期热液叠加改造期。The Liangjiagou Yindongshan Pb-Zn-Ag polymetallic ore deposit occurs in the the Jixian System Wumishan carbonate strata, layer control feature significantly.Its ore minerals were systemtically studied on the basis of thin section and polished section microscope observation.According to the geological features,mineral characteristics and penetration relationship of minerals,the authors have made divison of metallogenic stages,consider that the ore deposit at least gose through two metallogenic stages,that is, the original deposition of hydrothermal ore-forming stage and post-stack reconstruction period.
