Dolomite luster.

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. HistoryDolomite: Dolomite is a mineral that most often forms as an alteration of calcite, as magnesium replaces much of the calcium in the crystal structure. Consequently, it is not unusual for the two minerals to occur together. Both minerals exhibit the same well-developed rhombohedral cleavage and have roughly the same hardness. Pearl Spar - Grouping of white to pinkish curved Dolomite crystals with a pearly luster. USES Dolomite is used to make magnesia, which has important medicinal applications. It is important in the chemical industry for the preparation of magnesium salts. It is also used in soil mixtures to lower the acid levels of the soil.The Dolomite Group minerals are best told apart – and from calcite – by their S.G. when color and habit coincides.

Dolomite is composed of calcium and magnesium carbonate, and is quite similar to calcite. There are a few different varieties of dolomite. Pale brown, gray, or white dolomite with a pearly luster is called pearl spar. Brown dolomite, colored by iron, is called bitter spar. Dolomite crystals can also be colorless, yellow, or pink.

Streak is brownish, luster is resinous to adamantine, Sphalerite, usually in association with the lead sulfide galena, occurs in contact metamorphic deposits, in replacement deposits within limestone and dolomite, and in veins. Much is fluor. in UV
