1. (Minerals) a white mineral often tinted by impurities, found in sedimentary rocks and veins. It is used in the manufacture of cement and as a building stone (marble). Composition: calcium magnesium carbonate. Formula: CaMg(CO3)2. Crystal structure: hexagonal (rhombohedral)
2. (Geological Science) a sedimentary rock resembling limestone but consisting principally of the mineral dolomite. It is an important source of magnesium and its compounds, and is used as a building material and refractory

dol•o•mit•ic (ˌdɒl əˈmɪt ɪk) adj.
1. A gray, pink, or white mineral consisting mainly of a carbonate of calcium and magnesium. Dolomite occurs as rhombohedral crystals with a pearly to glassy luster. It is a common rock-forming mineral.
2. A sedimentary rock containing more than 50 percent of the mineral dolomite by weight.
A mineral or sedimentary rock made of calcium magnesium carbonate.
