Summary

Abundant microfossils have been discovered in middle and late Proterozoic iron and manganese ore deposits in eastern Guizhou Province, western Hunan Province, western Liaoning Province and Gansu Province. On the basis of microfossil assemblages and radiometric dating, the age of the iron and manganese ore deposits is considered to be in the range 1200–750 Ma.

A number of microfossils of Sphaerocongregus (or Bavlinella) have been found in rhodochrosite in these deposits. Based on the different preservation of microfossils in relation to the iron and manganese contents, it can be inferred that cyanobacteria are directly or indirectly implicated in the genesis of these iron and manganese ore deposits.
