| 摘 要： | Abundant microfossils and organic residuals have been discovered by SEM and normal palynological maceration from manganese ore beds intercalated in late Proterozoic glacial rock units in western Hunan Province and eastern Guizhou Province. Taking isotopic dating into consideration, the age of manganese ore deposits in both regions is suggested to be about 750 Ma. A distinct character is that a great quantity of colonial microfossil——Sphaerocongregus (or Bavlinella) and their degradational variants have been obtained from rhodochrosite. Their biological and biochemical functions, combined with the geochemical effect of manganese in different ways, may play an important role in the manganese cycle.
