These deposits were formed as the result of late mobilization, transportation and concentfation of the previously enriched ore-forming mate- rials in several ore-bearing formations formed during the rift stage. So the metallogeny of these deposits in the rift shows both inheritance and new generation of the ore-forming materials. In future ore-searching practice, attentions should be paid on the studies of the ore-bearing formations in the rift, on the multiple stages of metallogeny and and on multiple derivations of the ore-forming materials.展开更多
造山型金矿为世界上最重要的金矿类型,被认为是变质流体成矿的典型代表(Goldfarb et al.,2005)。此外,变质地体中部分贱金属矿床(Cu、Pb、Zn)具有与造山型金矿类似的地质和地球化学特征,也被认为形成于变质流体(如Leach et al.,1998;Zho...造山型金矿为世界上最重要的金矿类型,被认为是变质流体成矿的典型代表(Goldfarb et al.,2005)。此外,变质地体中部分贱金属矿床(Cu、Pb、Zn)具有与造山型金矿类似的地质和地球化学特征,也被认为形成于变质流体(如Leach et al.,1998;Zhong et al.,2012,2013),部分学者亦将其命名为造山型矿床(陈衍景,2006)。展开更多
