| 摘 要： | 新疆阿克陶县奥尔托喀讷什地区锰矿在近年来取得重大找矿突破，目前该锰矿区已累计查明资源储量1206.74万吨，矿床平均品位37.82%。本文通过钻探、坑探和各类地质测量全面分析了奥尔托喀讷什地区的区域地质特征、赋矿地层及锰矿的矿床地质特征和成因。查明了区内地层层序，并确定上石炭统喀拉阿特河组第三岩性段（C2k3）是本区主要的含锰岩系，是锰矿体的主要赋存层位。探明了区内矿体的产出形态、规模、产状、矿石类型及结构构造，分析了区内锰矿形成的地质背景、成矿条件，并初步建立了奥尔托喀讷什锰矿的成矿模式，进而为该区找矿突破提供了理论支撑。

| Abstract: | The manganese ore prospecting in the Aoertuokanashi region of Akto county, Xinjiang has achieved a major breakthrough in recent years. At present, the proved resource reserves of this ore has reached 12.0674 million tons with an average grade of the deposit 37.82%. This work has analyzed the regional geologic setting, ore-bearing strata, geologic features and genesis of the deposit in the Aoertuokanashi region based on data from drilling, pit exploration and various geological surveys. The stratigraphic sequences in the area has been ascertained, where third lithologic member (C2k3) of the Karatite Formation in the Upper Carboniferous Group was identified as the main manganese-bearing rock series. The occurrence, scale, shape, ore type and structure of the ore body in the area has been clarified; and the geological background and metallogenic conditions of manganese ore formation has also been analyzed. In combination with previous research, the ore-forming model of the Aoertuokanashi manganese deposit was initially established, which provides a theoretical support for further breakthrough in prospecting for this area. |
