A fluctuating solution to the dolomite problem - Science

2023.11.23  A precipitate of disordered calcium-magnesium carbonate (a proto-dolomite) will reorganize into ordered dolomite by ripening. Ripening, or maturation, is a very slow process that can last millions of years at constant ambient temperature, but fluctuations in

Dolomitization - Wikipedia

Dolomitization is a geological process by which the carbonate mineral dolomite is formed when magnesium ions replace calcium ions in another carbonate mineral, calcite. It is common for this mineral alteration into dolomite to take place due to evaporation of water in the sabkha area. Dolomitization involves substantial amount of recrystallization. This process is described by the stoichiometric equation

Flow, dissolution, and precipitation in dolomite

Evamy [1967] described dedolomit-ization as a one-step process in which dolomite is replaced by the formation of calcite. In contrast, Kenny [1992] considers dedolomitization as a two-step
