The organogenic dolomite model:Mechanism,progress and significance

Dolomite is common in stratigraphic record.It is widely distributed in the carbonate platform in ancient times,however,rarely found in the Holocene sediments,which constitutes a mystery.The research achievements in last two decades indicate that sulfate reduction,methanogenesis, anaerobic methane oxidation and aerobic respiration in the early diagenetic process induce dolomite precipitation.Bacterial cells and extracellular polymeric substances(EPS)with negative charges could concentrate Mg and Ca ions in solution.At the same time,these three oxidation-reduction reactions generate bicarbonate and raise the concentration of reactants of the pore water.All of the above favor the formation of a micro-environment that is supersaturated respect to dolomite around cells,resulting in dolomite precipitation.This is a new dolomitization model.Microbial activity and organic matter are the most important factors for the precipitation of dolomite.The special spherical shape and carbon isotope characteristics of dolomite can be used to identify an organogenic origin.This organogenic dolomite model has significant implications for the origin of the massive dolomite in geological history and "Dolomite Problem" research.
