Common mineral with the formula CaMg (CO3)2, found chiefly in rock masses as dolomitic limestone, but occurring sometimes in veins. It has a hardness of 3.5 to 4 and a specific gravity of 2.85. Dolomite crystallizes in the hexagonal system. It is usually colorless, white, or pink, but may be brown, black, or green, depending on the impurities present.
Dolomite (pronounced /ˈdɒləmaɪt/) is the name of a sedimentary carbonate rock and a mineral, both composed of calcium magnesium carbonate Ca Mg (C O 3) 2 found in crystals.
Dolomite, which is named for the French mineralogist Deodat de Dolomieu, is a common sedimentary rock-forming mineral that can be found in massive beds several hundred feet thick.
