摘　　要：广西靖西县岜爱山矿区锰矿层赋存于泥盆系上统五指山组中段条带状、薄层状硅质泥岩或硅质灰岩中,深部为原生碳酸锰矿,地表及浅部为次生氧化锰矿。矿区内矿体主要受安宁背斜、品明向斜的控制,矿层产状稳定,厚度变化不大,连续性好,矿床成因类型为"下雷式""沉积变质型锰矿床"。The manganese ledge in Baai Mountain of Jingxi town, Guangxi Province was host in the upper Devonian banded and lamella silica mudstone and stone which is in the middle member of five-fingers mountain group. The deep part is composed of primary manganese carbonate and the associated manganese oxides on the surface and the sallower part. The orebody is controlled by the Arming anticline and Pinming syncline, with the stable ledge occurrence, small thickness variety and well continuity, the deposit formation cause type is ＂Xialei type＂ and ＂sedimentary metamorphic manganese deposit＂.
