微生物与沉积岩的协同演化
Coevolution of Microorganisms and Sedimentary Rocks
摘要
Abstract
[Significance]Earth differs from other planets because of the presence of the biosphere.Microorganisms in the biosphere have played,and are playing,important roles in shaping Earth habitability owing to their wide spa-tiotemporal occurrence,diverse metabolism functions,rapid multiplication,and great abundance.To explore the co-evolution of microorganisms and sedimentary rocks is of great significance in understanding the processes and dynam-ics of the formation of Earth habitability.[Progress]The Archean is dominated by magmatic rocks,and its sedimen-tary rocks are primarily related to physical processes.However,banded iron formation is related to the contribution of photoferrotrophic bacteria.Significant changes occurred in the Proterozoic when sedimentary rocks overtook magmatic rocks in abundance and diverse biogenic rocks(calcimicrobialites and dolomites)greatly increased in abundance.Microbially-induced sedimentary structures were also diverse and occurred in great abundance.Mudstone began to in-crease in abundance at the end of the Proterozoic owing to the development of microorganisms on land,which generat-ed a new clay factory.The transition interval across the Neoproterozoic and Cambrian boundary witnessed the shift from siliceous to phosphatic and finally to calcareous rocks,coincident with the evolution from prokaryotes to eukary-otic microorganisms and finally to metazoans,showing their causal relationship.In the Phanerozoic,dolomite exhibit-ed a sharp decrease in abundance due to the metazoan expansion and its suppression on microorganisms.Green algae dominance in the Paleozoic shifted to the dominance of red algae in the Mesozoic and Cenozoic,favoring the expan-sion of calcium carbonate from shallow to deep water.In particular,carbonate factory showed the shift from skeleton limestones to calcimicrobialites for at least five times,in association with the occurrence of anachronistic facies as well as microbially-induced sedimentary structures;these are due to the transient expansion of microbial communi-ties immediately after the biotic crisis.Mudstones increased in abundance immediately after the development of terres-trial ecosystems due to the innovation of a clay factory on land and the enhanced precipitation of clay minerals caused by organic-induced flocculation.[Conclusions and Prospects]Microbial involvement of sedimentation resulted in the biogenic formation of sedimentary rocks including banded iron formations,limestones,dolomites,phosphorites,siliceous rocks,and certain mudstones,which in turn have caused the coevolution of microbes and sedimentary rocks throughout Earth history.Current research has summarized such a co-evolution framework on the geological times-cales.Future studies will quantitatively define the abundance of various sedimentary rocks over geological time based on reanalysis of the geological database,and quantitatively analyze microbial sedimentary rocks to better understand the coupled deep Earth-surface processes.关键词
