• Dolomitization | mineralogy | Britannica

    Dolomitization, process by which limestone is altered into dolomite; when limestone comes into contact with magnesiumrich water, the mineral dolomite, calcium and magnesium carbonate, CaMg(CO 3) 2, replaces the calcite (calcium carbonate, CaCO 3) in the rock, volume for volumeDolomitization involves recrystallization on a large scale The dolomite mineral grains often show distinct faces

  • Protodolomite | mineral britannica

    Other articles where Protodolomite is discussed: dolomite: Crystal structure: The term protodolomite is frequently applied to Holocene dolomites (those formed during approximately the last 11,700 years) that have less than ideal dolomite structures Most dolomites of ancient dolostones, however, appear to be well ordered Modifications that may reflect diverse calciumversusmagnesium layering

  • Carbonate mineral | Britannica

    The commonest varieties, calcite, dolomite, and aragonite, are prominent constituents of certain rocks: calcite is the principal mineral of limestones and marbles; dolomite occurs as a replacement for calcite in limestones, and when this is extensive the rock is termed dolomite; and aragonite occurs in some recent sediments and in the shells of organisms that have calcareous skeletons

    A pearly sedimentary mineral composed of calciummagnesium carbonate that was first described in 1791 by the French naturalist Deodat de Dolomieu in the Dolomite mountains in Italy Domolite rock is hard, crystalline, carbonaceous stone with high percentage (90 % to 100 %) of the mineral dolomite It is found in ledge formations throughout Europe (Saxony, Switzerland, Italy, France, Spain

    Dolomite (CaMg(CO 3) 2) is a carbonate mineral in which half the calcium in calcite is replaced by magnesium Dolomite forms as a result of reaction between calcite and Mgbearing groundwater Calcite can become partially replaced by dolomite This replacement can take place soon or long after formation of the limestone The term dolomite is used both for the mineral CaMg(CO 3) 2 and the rock
