摘 要:秦岭型铅-锌矿床是产于北秦岭华力西褶皱系泥盆纪地层中,由海相碳酸盐岩及细碎屑岩系容矿的热水沉积-改造型铅-锌矿床。它可进一步划分为热水沉积矿床(厂坝式)及热水沉积改造矿床(毕家山-铅硐山式)两个亚类。与世界古生界著名铅-锌矿床对比,它包括了热水沉积矿床(Meggen型)和热水改造矿床(Mississippi Valley型)的一些特征,但又有别于它们成为一个独立类型。The Qinling-type lead and zinc ore deposit is located in the Qinling fold belt, occurring in the Devonian marine fine clastic and carbonate rocks. It is a sedimentary-reworked ore deposit which is basically a sedimentary deposit further hydrothermally reformed. It may be separated into two subtypes: one is the sedimentary ore deposit (Changba subtype); and the other is the sedimentary-reworked ore deposit (Bijiashan-Qiandongshan subtype).In comparison with some famous lead and zinc ore deposits in the world which occur also in Palaeozoic formations, it seems evident that the Qinling-type lead and zinc deposit is an important transitional type between the Meggen-type and the Mississipi type.
