| 摘 要： | 我国地质构造单元的演化千差万别，形成了各具特色的多种成矿地质背景。金矿类型复杂，金矿床的空间分布呈现明显的不均一性并具有区域集中的趋势。不同的大地构造单元有不同的金矿地质特征。金的成矿时代以燕山期最为重要，吕梁一晋宁期和华力西期次之，再次为五台期和喜马拉雅期。成矿时代具有显著的地域差异。我国金矿资源比例为岩金５１．７６％，伴生金占３１．４８％，砂金占１６．７６％。金矿控矿构造特征明显。三大成矿域有

| Abstract: | China is tectonically situated in the junction of Eurasian plate,Pacific plate and Indian plate.The evolution of various tectonic units differs in many aspects,and has createdmany different geological settings for mineralization.The types of gold dePosits are comPlex.The gold deposits in China distribute spatially unevenly and tend to concentrate in certainregions.Different tectonic units have different gold geological characteristics.Among the goldmineralization ages in China,the most important is the Yanshanian,then follow successivelythe Luliang jinningan,the Variscan,the Wutainian and the Himalayan. The mineralizationages show obvious spatial difference.Of the total gold reserves of Chian,rock gold is 51.76%,placer gold is 16.76% and associated gold is 31.48%.The structural control of gold deposits is rather clear.The three metallogenic domains have their evolution history of tectonomagmatism and corresponding metallization.Some favorable tectono-magmatism belts in the various massif marginal activity belts,pal-upheaval regions and main folded orogenic beltsare considered favorable regions for gold metallization. |
