The Dolomite occupies approximately 2% of Earth's crust. Dolomite formation occurs under anaerobic conditions. The mineral occurs in the form of dolomite marble, dolomite carbonatite, and dolomite-rich veins. Magnesium in Dolomite can be substituted by other cations like ferrous iron, lead, barium, zinc, and manganese.
