| 摘 要： | 大兴安岭地槽褶皱系是兴安岭—内蒙地槽褶皱区的主体。区内已发现旁开门、二十四号桥、宽河、泥鳅河等金矿床,多宝山、小多宝山、三矿沟等伴生金矿床(其中多宝山铜矿体的伴生金储量超过70×103kg)及四道沟东山、北西里、八里岗金矿点等共一百多处金矿床(点)。其中构造蚀变岩型和火山热液型金矿是区内主要成矿类型。研究区地壳构造运动强烈,既有古老基底构造的继承性,又受中新生代环太平洋成矿作用的叠加,为多期复合成矿的有利地段(多宝山铜 金矿田),是我国东北部重要的岩金矿化集中区。

| Abstract: | The Da Xing'anling Geosynclinal folded system is the main part of the Xing'anling-Co-Inner Mongolia Geosynclinal folded area. More than 100 gold mineral occurrences such as the Pangkaimen,Ershisihaoqiao, Kuanhe, Niqiuhe gold deposits and the Duobaoshan,Xiaoduobaoshan,Sankuanggou associated gold deposits and Sidaogoudongshan,Beixili,and Baligang gold points have been found, among them, the associated Au reserves of the Duobaoshan Cu ore body is over 70 000 kg. The tectonic alterated type and volcanic hydrothermal type gold deposit are the essential mineralizations in the area. This area had strong tectonic movement of crust, which includes the succession of the old basement tectonics and the overprint of circle-Pacific mineralization in Cenozoic, and is the favorable area for mineralization (for example, the Duobaoshan Cu-Au deposit) and is the important gold mineralization center of the northeast part of China. |
