摘要
盖塔哈(GUETTARA)锰矿含矿地层为上元古代的湖相火山—沉积岩岩系,矿体呈似层状、透镜状产出;矿体矿石矿物多样,因此,该矿床以锰矿为主,还伴生中型砷矿床。属湖相火山—沉积变质锰矿床。
The ore-bearing bed of Guettara Mn deposit is Upper Proterozoic lacustrine facies volcanic sedimentary rock series. The orebody is stratoid, lenticular, the ore is diverse. Therefore, there is an associated middle scale As deposit besides the main Mn deposit, belonging to the lacustrine facies volcanic sedimentary metamorphic Mn deposit.
