Minerals are classified according to their chemical properties. Except for the native element class, the chemical basis for classifying minerals is the anion, the negatively charged ion that usually shows up at the end of the chemical formula of the mineral. For example, the sulfides are based on the sufur ion, S 2–.Dolomite's luster is vitreous and pearly. Dolomite is brittle and has a Mohs hardness rating of 3.5 to 4. Where are dolomite rocks found?

Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.Dolomite Testing. Dolomite consists of calcium magnesium carbonate and hence is called a carbonate mineral.

Dolomite ( / ˈdɒl.əˌmaɪt, ˈdoʊ.lə -/) is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg (CO3)2. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite (see Dolomite (rock) ). An alternative name sometimes used for the dolomitic rock type is dolostone.
