摘　　要：根据我国大陆时空演化及结构分区特点,本文分析了东亚壳体南部地洼区成锰的控制因素;结合两类锰质来源,划分出区内成锰条件各异的三类成矿域;讨论了优质富锰矿在各成矿域的形成方式、特点和找矿方向。Based upon the features of the time-space evolution of China continent and its structure division,in this paper an analysis ismade on controlling factors for the formation of Mn-ores in the diwa district in the south of East Asian crustal body.In combina-tion with two different source beds of Mn ores,three metallogenetic provinces with diefferent Mn-ore forming conditions are class-fied.Furthermore,the formation patterns of super quality—high grade Mn-ores in different provinces,their characteristics and ex-ploration guides are also discussed.
