Dolomite (Mineral)
The two major types of carbonate rocks are limestone (CaCO 3) and dolostone, primarily composed of the mineral dolomite (CaMg (CO 3) 2 ). Carbonate rocks can be of various origins like: Chemical, which are formed by precipitation of bicarbonate and mainly originating in marine muds ( Cosse´, 1993 ), and.

Dolomite thermal behaviour: A short review
The mineral dolomite is a double carbonate of calcium and magnesium with a chemical formula CaMg (CO 3) 2 [ 1 ]. Dolomite can originate naturally in two forms: primary and secondary dolomite [ 1, 2 ]. The first has been formed from the direct precipitation of solutions rich in carbonate, magnesium and calcium ions.
