===Dolomitization===

''Dolomitization'' is a diagenetic process that converts limestones to [[dolostones]] through a microchemical process of calcium carbonate dissolution and dolomite precipitation. Dolomitization can change the rock fabric and the petrophysical properties significantly because the dolomite [[Crystallization|crystal]]s are commonly larger than the replaced limestone particles. Dolomite cement systematically grows on the dolomite crystal faces, reducing reservoir quality. Dolomitization requires the addition of large quantities of magnesium through fluid flow.
