Massive formation of early diagenetic dolomite in the Ediacaran ocean: Constraints on the “dolomite problem”
Paleozoic and Precambrian sedimentary successions frequently contain massive dolomicrite [CaMg(CO₃)₂] units despite kinetic inhibitions to nucleation and precipitation of dolomite at Earth surface temperatures (100 °C, thus raising doubt about the validity of these deposits as archives of Earth surf...
