摘要
The Datangpo Stage of the Neoproterozoic was an important period for manganese mineralization and this can be proved by a number of manganese deposits found in eastern Guizhou Province and western Hunan Province, China. Recent discovery of manganese deposits in Gaozeng, Congjiang County, southeastern Guizhou Province indicates that extensive manganese mineralization may occur in the Datangpo Stage and mineralization settings were even much complicated. Research of sedimentary features, mineral assemblage and geochemistry of the manganese deposits of the Datangpo Formation shows the enrichment of Cu, Zn, Ni, Nb, Co, Mo, As, Sb, Sr, Ba, V, Ga, Ag, Th, and U, especially Pb, Co and W, strongly suggesting that Mn-bearing rock series is hydrothermal sedimentation in origin. Hydrothermal exhalative sedimentation and exploration for the manganese deposits in this area should target synchronous deep-seated faults.
