摘　　要：梭落底地区碳酸锰矿是云南省砚山地区近年来新发现产于中三叠统法郎组碎屑岩中的重要碳酸锰矿,在滇东南具有代表性。该类锰矿以矿层厚度大,出现多层而且相互平行产出为特征,与相邻的斗南、老乌锰矿进行对比,该碳酸锰矿沉积的氧化—还原界面深度比斗南、老乌锰矿更深,该类锰矿的形成很大程度上受下伏地层个旧组碳酸盐岩基底古地理的控制。The Mn carbonate deposit in Suoluodi area has been discovered in recent years, winch is an im- portant Mn carbonate deposit in Mid T Falang Formation clastic rock and representative one in SE Yunnan. These Mn deposits are characterized by thick ore bed, parallel occurrence of many ore beds. The oxidation-reduction boundary of this Mn deposit is deeper than those of the neighbor Dounan, Laowu Mn deposit. The formation of this Mn deposit is controlled by the palaeogeographical environment of underlying Gejiu Formation carbonate rock basein very high degree.
