| 摘 要： | 系统总结了我国金矿成矿与分布的若干特征,即中国三个巨型深断裂体系控制金矿的总体分布格局;金矿在地区分布上的不均衡性;赋存金矿主岩的“偏集性”,合缘与基底构造层隆起区对金成矿带(区)的主要控制作用;断裂构造对金矿成矿的分级控制规律和花岗岩特别是燕山期花岗岩对金矿成矿的重要意义。我国金矿大致分为五个成矿期,即晚太古—早元古代、中晚元古代、古生代、中生代及新生代成矿期。

| Abstract: | This paper systematically summarized the charactcritics of forming and distribution of gold ore deposits in China,and included that the bulk distribution patterns of gold mineral deposits were controlcd by three giant abysmal rifts system. The nonuni-formity of gold deposits distribution in the area, the "bias "of gold host -rock , main control of platform margin and upward district of basement tectonic layer on gold ore - forming belt (district), the law of control of rift structure grade on gold ore-forming and the important significance of the granite,especially Yanshan stage,for gold ore-forming arc the main fcatllrcs of gold ore deposits. The gold ore deposits in China can be roughly divided into five mineralization periods :i. c. Later Archcan-Early Protcrozoic,Middle-Later Protcrozoic, Palacozoic Mcsozoic and Ccnozoic cra. |
