摘      要：Microbes are well-known for their great diversity and abundance in modern natural *** also are believed to pro-vide critical links among higher organisms and their associated ***,the low diversity of morphological fea-tures and structures of ancient microbes preserved in sediments and rocks make them difficult to identify and *** diffi-culty greatly hinders the investigation of geomicrobes throughout Earth ***,most previous paleontological studies have focused on faunal and floral ***,geomicrobial functional groups(GFGs),or a collection of microbes featured in specific ecological,physiological or biogeochemical functions,are suggested to provide a way to overcome the difficulties of ancient mi-crobe *** are known for their great diversity in ecological,physiological and biogeochemical *** addi-tion,GFGs may be preserved as the biogeochemical,mineralogical and sedimentological records in sediments and *** reviewed the functions,origins and identification diagnostics of some important GFGs involved in the elemental cycles of carbon,sulfur,nitrogen and *** were further discussed with respect to their significant impacts on paleoclimate,sulfur chemistry of ancient seawater,nutritional status of geological environments,and the deposition of Precambrian banded iron formations.
