| 摘 要： | 我国地处欧亚板块、太平洋板块和印度板块的交汇地带，其区域成矿构造背景可分为古亚洲成矿域、滨太平洋成矿域和特提斯－喜马拉雅成矿域。它们有着独具的演化历史与成矿特征。因此，我国金矿成矿环境比较多样，矿床类型亦较繁多，并多具活动性陆壳的成矿特征。金矿时空分布具有一定的地域差异，热液矿床多具后生特征。矿床类型以交代－重熔花岗质杂岩中的玲珑－焦家式金矿为最重要，前寒武纪变质岩中石英脉型和糜棱岩带型金矿次之，微细浸染型和火山热液型金矿亦有一定远景，金矿资源比为：岩金占５１．７％，伴生金占３１．４８％，砂金占１６．７６％。

| Abstract: | China is tectonically located at the intersection of Eurasian ,Pacific and Indian plates. In terms ofits regional metallization setting,China can be divided into Paleo-Asian,marginal-Pacific domain andTethyan-Himalayan moga-provinces with different evolution history and mineralization characteris-tics.The mineralization background for gold deposits in China is various. The types of gold depositsare complex and characterized by active continental crust mineralization. The time and space distribu-tion of guld deposits varies from arca to area.Hydrothermal gold depeits are mcatly epigenitic in char-acter. The most important type of depeit is Linglong-Jiaojia type in metasomatic granitic complex,followed by quartz vein type and mylonitized zone type in Precambrian metamophic rocks. Fine im-ptegration type and volcanic hydrothermal type gold deposits are also potential.The proportion of goldresources is:51.7%primary gold,31.48% by-preduct gold and 16.76%placer gold. |
