Dolomite. Dolomite is the name of a sedimentary carbonate rock and a mineral, both composed of calcium magnesium carbonate Ca Mg ( C O 3) 2. As a mineral, it is found in crystals. Dolomite rock (or 'dolostone') is mostly made of the mineral dolomite. Limestone that is partially replaced by dolomite is referred to as dolomitic limestone.

Dolomite is an earthy mineral. It is a Carbonate mineral, also known as Calcium Magnesium Carbonate. Generally it is white to off white in color. Its chemical formulae is CaMg (CO₃)₂. This mineral crystallizes in the Trigonal system. Gujarat in INDIA is rich in Dolomite deposits. Dolomite is a mineral that has a special saddle-shaped crystal.

Dolomite. Dolomite is, after calcite, the second most important and abundant of the carbonate minerals. Chemically and structurally, it may be regarded as calcite with half the calcium ions replaced by magnesium. Iron or manganese may substitute for magnesium in dolomite, forming isostructural series with ankerite and kutnohorite.

Dolomite is a mineral very similar to calcite, the calcium carbonate that forms the shells of many foraminifera, mollusks, and bivalves whose accumulation at the bottom of the seas created the well-known limestones. The difference between dolomite and calcite is that the former contains equal parts calcium and magnesium.

Dolomite is a calcium/magnesium carbonate mineral. It has a formula unit composition of CaMg(CO 3) 2. Dolomite has a trigonal crystal system with rhombohedral habit. In ideal dolomite, calcium and magnesium are separated into completed separate planes, quite unlike magnesian calcites in which Mg randomly substitutes for Ca.

Dolomite, or dolostone, is a carbonate sedimentary rock made mostly from the mineral dolomite, CaMg (CO3)2. It commonly occurs in association with limestone and shares many of the same properties, but reacts only weakly with acid. Dolomite often has a sugary texture and is typically off-white to gray in color.
