摘    要:本文讨论了中国大地构造演化对金矿成矿作用的制约。认为中国华北克拉通化时间较晚,变形变质作用强烈,显生宙又遭受多次板块运动的叠加改造,有利于前寒武纪金矿的形成和保存。显生宙以来在中国古陆块周边发生了四次大的板块碰撞或俯冲造山运动,即塔里木-华北克拉通北缘及其以北地区的海西期造山运动;昆仑-祁连-秦岭地区的海西-印支期造山运动;西南地区印支-喜山期的喜马拉雅造山运动,东部大兴安岭-太行山-豫西-鄂西=

关 键 词:大地构造演化 造山运动 成矿作用 金矿床

Abstract:Au metallogeny in China is constrained by geotectonic euolution.The North China was lately cratonized with intense deformation and metamorphism on which multiple plate tectonic movements were overprinted thus the Au deposits formed before Cambrian period could not survive.Since phanerozoic took place four tectonic movemcnts in the surrounding areas of the palaeo china continent,i.e.Hercynian orogeny at the north margin area of Tarim North china craton and the area to north, Hercynian indo china orogeny in Kunlun Qilian Qinling Area,Indo China Himalayan orogeny in Southeast China,the Mesozoic Yanshanian orogeny in East Daxinganling Area,Taihangshan Yuxi Area,Erxi Xiangxi Area.Gold deposits in China were formed in the late period of the four orogenic movements,especially in the late period of Yanshanian Orogeny.
Keywords:geotectonic evolution  orogeny  Au metallogeny
