摘要
介绍了近年来超大型金属矿床理论研究现状,探讨了超大型铜、铅、锌、金和铂族等有色贵金属矿床的成矿构造背景,认为该类超大型矿床产出的主要全球构造背景为板块俯冲带和大陆裂谷,并论述了不同构造背景中超大型矿床的成因类型、矿床特征、控矿构造和矿床空间展布规律以及裂谷构造垂向分带和不同地史时期裂谷与超大型矿床的关系,对当前研究工作中一些问题进行了讨论。
Some recent advances in the research of superlarge metal deposits are introduced in this paper, The main global tectonic settings of superlarge Cu,Pb,Zn,Au and Pt depositsare preliminarily classified into subduction zones and continental rifts. The genetic types, mineralization features and ore-controlling structure types as well as the spatial distribution patterns of superlar.ge metal deposits in different tectonic settings are described, with stress on the vertical zoning of rift systems and the restraint of rift structures in various geologic periods on superlarge metal deposits. The paper also reviews some current problems in research about this field.
