构造-岩浆活化与中生代金矿床——以东亚金矿集中区为例

Structure-magma activation and Mesozoic gold deposit——with East Aisa gold deposit concentration zone as example

全球性构造-岩浆活化作用研究在亚洲大陆受到特别的关注;阿尔丹—斯塔诺夫地盾与中朝地盾及其边缘古生代—中生代造山带内构造改造强烈,大规模金的成矿作用与侏罗纪初期的"成矿大爆炸"相联系;东亚金矿集中区大量出现的中生代金矿床即是例证;东亚金矿集中区矿床类型多样化,金矿床地质-成因模型具专属性。

The researches on global structure-magma activation draw special attentions in Asia. The structural reformation in Aldanian-Stanovoy shield, China-Korea shield and their marginal Paleozoic-Mesozoic orogen is intensive. Large-scale gold mineralization connected with the early Jurassic mineralization big bang. The large number of Mesozoic gold fields in East Aisa gold deposit concentration zone is the illustration. The gold deposits in the concentration zone are of different types and the geological-genetic model of the gold deposits has some specialization.
