Dolomitization - an overview ScienceDirect Topics

Dolomites are carbonate rocks mainly composed of the mineral dolomite. The mineral is stable in seawater in nature and not known examples of its direct extraction from seawater in large quantities required for origin of dolomite rocks. Dolomite occurs by suppression of aragonite or calcite, i.e. dolomitization process.
