• Dolomite: A sedimentary rock known as dolostone or

    Dolomite, also known as \"dolostone\" and \"dolomite rock,\" is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO3)2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater.
