| 摘 要： | 玛尔坎苏锰成矿带沿玛尔坎苏河上游分布,东西延伸超过40 km。该成矿带以石炭系细碎屑岩-碳酸盐岩沉积建造为主,属典型的海相沉积型锰矿。锰矿带含矿层位稳定,矿体厚度大(最厚30.61 m),品位富(平均品位24%～35%,最高68.5%),矿石矿物以菱锰矿为主,属于低铁中磷类型。综合分析认为玛尔坎苏锰成矿带形成于滨浅海环境,成锰期处于一种安静、还原的水体环境。锰质来源以深源物质为主,与火山活动、热水活动关系密切。

| Abstract: | In recent years,we has made a great breakthrough in the exploration of manganese ore in aketao County of Xinjiang that locates in the northwestern China,we discovered and evaluated the Maerkansu manganese ore belt.This metallogenic belt distributes along the upstream of Maerkansu River,with a length of more than 40 km from west to east. The metallogenic belt is mainly composed of the carboniferous fine clastic rock-carbonate sedimentary,Belonging to the typical marine sedimentarymanganese deposit.The metallogenic belt is stable with large thickness(Max 30.61 m) and rich grade(Average 24~35%, Max 68.5%).The ore minerals are mainly rhodochrosite and belongs to a type of lowiron with middle phosphorus;The Maerkansu manganese metallogenic belt formed in a quiet and reductive water.The main source of manganese is deep matter,which is closely related to volcanic activity and hydrothermal activity. |
