摘　　要：我国氧化锰矿主要分布在北纬２３°带内，带内氧化锰矿分布广，氧化深度大，忆矿石品位富，矿床规模大。氧化锰矿形成的条件为：带内有丰富的原生沉积锰矿层或矿胚层；年积雨量充沛；年积温量高；热带雨林广布，微生物引起的生物化学作用强烈。氧化锰矿主要分布在向斜构造和地貌洼地内。The manganese dioxide mines in our country are mainly distributed along the 23°north latitude line. These mines have a wide occurrence, strong oxidation, high tenor of manganese ores, and a great dimension of ore bodies. The conditions for the formation of manganese dioxide ores include: plenty of primary sedementary ore beds or protores, high rainfall and temperature, widespread rainforest, and an active biochemical process caused by microbial population. The manganese dioxide lie mainly in the synclines and topographic depressions.
