摘要
Some high quality manganese ore deposits of Cbina are found to be polygenetic compound ore deposits which are the products of diwa mineralization. Liancheng manganese ore district, Fujian, is a typical example. Similar deposits can be found in East GuangdongWest Fujian and Hunan. The genesis of some ore deposits in Southeast Yunnan, for example,those in Deunan and Beixian,maybe related to diwa mineralization.Geological conditions of the mineralization of some high grade manganese ore deposits have been analysized and comPared with other comparatively poor manganese ore deposits.The genesis and perspective of higb quality mamganese ore deposits is discussed based on diwa theory.It is pointed out that South-East China diwa region,the South tip of South-North diwa region and some parts ofYunnan-Guizhou diwa region are more prospective for the reconnaissance geologicaI survey and exploration of high grade polygenetic compound weathering manganese and rhodochrosite-alabandite ore deposits in Cbina.
