Dolomite is the name of both a carbonate rock and a mineral (formula: CaMg(CO3)2) consisting of a calcium magnesium carbonate found in crystals. Dolomite rock (also dolostone) is composed predominantly of the mineral dolomite. Limestone which is partially replaced by dolomite is referred to as dolomitic limestone, or in old U. S. geologic literature as magnesian limestone.

Dolomite mineral crystallizes in the trigonal - rhombohedral system. It forms white, gray to pink, commonly curved, crystals although it is usually massive. It has physical properties similar to those of the mineral calcite, but is less soluble in dilute hydrochloric acid. The Mohs hardness is 3.5 to 4 and the specific gravity is 2.85.

Dolomite was first described in 1791 as the rock by the French naturalist and geologist, Deodat Guy Tancrede de Gratet de Dolomieu (1750-1801) for exposures in the Dolomite Alps of northern Italy.
