摘要
白银厂矿床的成因经历了较长时期的喷发沉积成因与热浓成因之争。本文依据大地构造背景、成矿环境、矿床特征和火山作用与成矿关系等实际资料的研究和新认识,进一步论证了该矿床成因,经与国外有关矿床对比,认为该矿床为黑矿型海底喷气-沉积块状硫化物矿床。并对矿床成因研究方面所取得的进展作了评述。
The Baiyinchang deposits are polymetallic massive sulfide deposits occuring in Early-Paleozoic submarine volcanic rocks. Since exploration, there have been two main different views regarding genesis of the deposits for a long period, volcanic eruptive-sedimentary and hydrothermal metasomatic genesis. On the basis of studies about tectonic setting, metallogenetic environment, features of deposits and relation between volcanism and mineralization, the author discusses the genesis of the Baiyinchang deposits and considers that the deposits are of submarine exhalative-sedimentary massive sulfide deposits associated with tensional island-arc environment. The Baiyinchang sulfide deposits belong to Kuroko-type massive sulfide deposits as compared with some other massive sulfide deposits of the world. Finally, this paper reviews briefly the development of the genesis of the deposits,
