摘要
By analysis the geological characters of Yanglizhang section and Lijiawan section and the drilling information of Yanglizhang manganese deposit,according to Datangpo- type manganese palaeo- gas seepage metallogenic system and metallogenic theory,the changing character of mineral component and structure on the plane are introduced,the distribution of orebody on the plane and the minor axis direction along manganese formation sedimentary basin are summarized and the relation between ore- bearing rock thickness,ore grade and orebody thickness are discussed. The spatial distribution character of Yanglizhang manganese deposit is summarized and prospecting direction in NEE deep position and NW F1 fracture of this manganese deposit.
