Dolomite: Is a calcium magnesium

Dolomite is a calcium magnesium carbonate mineral and a rock-forming mineral that forms through dolomitization of limestone. Learn about its crystal structure, physical and optical properties, geological importance, and applications in industry and construction. Dolomite rock is defined as sedimentary carbonate rock composed of more than 50% mineral dolomite . Dolomite is characterized by its nearly ideal 1:1 stoichiometric ratio of magnesium to calcium. It is distinct from high-magnesium limestone in that the magnesium and calcium form ordered layers within the individual dolomite mineral grains, rather than being arranged at random, as they are in high-magnesium calcite grains. [13] In natural dolomite , magnesium is typically between 44 and 50 ... Dolomite is a carbonate mineral composed of calcium magnesium carbonate (CaMg (CO₃)₂) and is the principal component of the rock known as dolostone or dolomite rock. Nordenskiöldine Dolomite Group. Ankerite- Dolomite Series. A common rock forming mineral, also common in veins. Usually, when crystallised, it is found as druzes or clusters of small rhombohedral crystals, typically with a somewhat "saddle"-like shape, white to tan to pink in color.
