    J.C. Dixon, in Treatise on Geomorphology, 2013. 4.3.3.2 Calcrete and Dolocrete. Calcrete refers to terrestrial materials that have been cemented or replaced predominantly by calcium carbonate. It occurs in stages ranging from powdery to strongly indurated. The mechanism of calcification may be pedogenic or nonpedogenic, although pedogenic processes are widely viewed to be the most widespread

    Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO 3).The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite".. Other polymorphs of calcium carbonate are the minerals aragonite and vaterite.Aragonite will change to calcite over timescales of days or less at temperatures exceeding 300 °C, and vaterite is even
