Examples include the well-known kinetic inhibition of dolomite formation from seawater, and the formation of 'protodolomite
' rather than dolomite from evaporated groundwater or seawater (e.g., Machel and Mountjoy, 1986; Usdowski, 1994).
The Mg carbonate precipitated, combined with calcite precipitation, will likely represent the mixed Ca-Mg precipitate, called protodolomite
, that is observed in hypersaline environments.
