Petrological Summary: Reaction Series Leading from Carbonate Sediments to Carbonate Rocks
The simplest process of carbonate sedimentation is the precipitation from fresh-water, i.e. from solutions which are so low in dissolved magnesium that calcium is essentially the only important cation susceptible to forming a sparingly soluble carbonate. One of the most important factors determining carbonate solubility in any natural water is the partial pressure of CO2, which acts upon the activity product of the carbonate to precipitate via the equilibria (9), (10), and (11) (p. 103) among the various dissolved species related to the carbonate ion.
