福建浦城金竹坑—上厂地区铅锌钼多金属矿成矿规律研究

Study of Metallogenic Law of Lead-Zinc-Molybdenum Multi-Metal Deposits in Jinzhukeng and Shangchang Area of Pucheng County,Fujian Province

福建浦城金竹坑—上厂一带铅锌钼多金属矿以金竹坑铅锌矿、上厂钼矿为代表,金竹坑铅锌矿主要产于早元古代大金山组及大金山组与侏罗纪梨山组接触带,矿体主要受断裂构造控制,成矿作用与燕山晚期岩浆活动关系密切,属岩浆热液-充填交代型矿床;上厂钼矿与燕山晚期中酸性斑岩体密切相关,为斑岩型钼矿床。

The lead-zinc-molybdenum multi-metal deposits in Jinzhukeng and Shangchang area of Pucheng county, Fujian are represented by lead-zinc deposit of Jinzhukeng and molybdenum deposit of Shangchang. The Jinzhukeng lead-zinc deposit mainly occurred in Dajinshan formation in early Proterozoic, or between the layer of Dajinshan formation and Lishan formation in Jurassic is magmatic hydrothermal and filling replacement type deposit, as the ore bodies were controlled by fault structures and the mineralization was closely related to magmation in late Yanshan stage; While Shangchang molybdenum deposit is porphyry type molybdenum deposit which was closely related to intermediate-acid porphyry bodies.
