Microbial precipitation of calcium carbonate has played a major role in formation of carbonate platforms since the Archean. Also, microbial carbonates and biologically induced cement are important contributors to reef framework volume and rigidity in carbonate platform systems during times of significant environmental change including transgressive events in platform environments and the recovery interval following the major biotic crisis. The stratigraphic distribution of different types of microbial carbonates appears to vary within the sequence stratigraphic framework. Reefs and mounds within the Late Devonian carbonate platforms in Guilin, South China are formed primarily by calcimicrobes and biologically induced cement, representing the microbe-dominated and characteristic carbonate buildups within a reefal ecosystem that nearly all reef-building metazoans were absent after the Frasnian/Famennian biotic crisis. Microbial community and microbialite seem to be linked with specific palaeoenvironment and palaeoclimate, suggesting that they could be used as indicators of environmental change and biotic events.
