Dolomitization

 

the process of enriching calcareous silt (sediment) or limestone with dolomite through the substitution of MgCO3 for part of the CaCO3. There are two types of dolomitization: diagenetic, which occurs in silt during the process of its conversion into sedimentary rock, and epigenic, which occurs in already solidified limestone. Epigenic dolomitization is caused by the action of subterranean waters enriched with magnesium, as they pass through strata of dolomite, ultrabasic igneous rock, and so forth. A complete substitution of dolomite for the calcite rarely oc-curs with these secondary limestone changes. Usually dolomitized limestones are formed.
