| 摘 要： | 研究区大地构造位置位于天山—兴蒙造山系大兴安岭弧盆系上黑龙江盆地的西段,从大地构造单元划分和地球动力学属性分析,本区应为著名的蒙古—鄂霍茨克巨型近EW向构造—岩金成矿带的一部分,成矿构造地质环境、成矿特征与俄方毗邻地区基本一致,俄方从20世纪初至今,已在该带上发现了10多个大型—超大型岩金矿,均产于蒙古—鄂霍茨克推覆构造带内的中生代沉积盆地边缘或盆缘基底中。我国从90年代开始相继在上黑龙江盆地西段也发现了砂宝斯大型金矿床、老沟西和三十二站中型金矿床,说明该成矿带大地构造演化与金成矿关系存在内在的联系。

| Abstract: | The geo-tectonic position located in the western section of upper Heilongjiang basin,which located in Daxing’anling arc basin system of Tianshan-Xingmeng orogenic system.By analyzing the geo-tectonic unit division and geo-dynamics attribute,it shows that the study area is the part of Mongolia-Okhotsk super large scale tectonic-rock gold metallogenic belt nearly east-westward.The metallogenic tectonic geologic environment and metallogenic characteristic are basically same as in adjacent regions of Russia.Since 1900’s,they have found over ten super large-scale rock gold deposits,which occurred on the edge of sedimentary basin or basement of basin edge in Mesozoic.While we have found Shabaosi large-scale deposit,Laogouxi and Sanshierzhan middle-scale deposit in western section of upper Heilongjiang basin.It show that geo-tectonic evolution of the metallogenic belt has inner relationship with gold mineralization. |
