摘要:
孙家沟铅矿主要赋存于层山单元中细粒黑云母花岗闪长岩中, 为断裂构造控制的低温热液型矿床, 铅矿体主要受F2、F3断裂控制. 矿右主要金属矿物为方铅矿、闪锌矿及少量黄铁矿、黄铜矿等. 矿石结构主要为自形粒状结构、碎裂-角砾结构、脉状充填结构. 矿石构造以角砾状、浸染状、团斑状为主, 少数为块状构造、脉状构造等. ①号矿体铅品位主要介于0.314%~1.309%, 平均品位0.601%;②号矿体铅品位主要介于0.468%~1.460%, 平均品位0.776%. 根据工业指标圈定为低品位铅矿石.
Abstract:The Sunjiagou lead deposit is mainly hosted in the fine-medium-grained biotite granodiorites of Cengshan Unit, belonging to epithermal type, with the orebodies mainly controlled by F2 and F3 faults. The main metallic minerals of lead ore are galena and sphalerite, with minus of pyrite, chalcopyrite, etc. The ores are in idiomorphic granular, cataclastic-brecciated and vein-filled textures, with brecciated, disseminated and massive spotted structures dominated and a few massive and vein structures. The lead grade of No. 1 orebody ranges mainly from 0.314% to 1.309%, averagely 0.601%, while that of No. 2 orebody is 0.468%-1.460%, averagely 0.776%, which are delineated as low-grade lead ore according to industrial index.
