Dolomite is generally formed from limestone by dolomitisation, a digenetic process involving replacement of calcium in the calcite with magnesium. This may occur either soon after limestone deposition, by exchange with seawater, or after lithification by exchange with magnesium-bearing solutions. The process is partly a function of the permeability of the rocks and can therefore be very selective, giving rise to interbedded limestone and dolomite.
