摘要
本文阐明赋存在中国前中生代海相火山岩中的部分钩矿床并非一次成矿作用的产物。它们的成矿物质主要由火山作用或（和）同火山作用期的沉积物质供给，但也有后火山作用期的其他矿质来源。尤其是工业矿床，包括有后火山作用期由非火山作用以多种成矿方式在多阶段的叠加富集成矿。因此，它们是多因复成的。
Some copper ore deposits hostingin pre-mesozoic marine volcanic rocks on China is looked by this paper as many-stage products.Their ore-forming substances mainly from volcanism or(and)synvolcanic sediments,and partly from other ways in postvolcanic stages.There are superimposed and enriched mineralizations in many kind of ore-forming way included the volcanic and nonvolcanic in many stages after volcanism,especially the industrial ore deposits.Therefore,they are of polygenetic compound.
