MINERALS DOLOMITE is used as an ornamental stone, a concrete aggregate, a source of magnesium oxide and in the Pidgeon process for the production of magnesium. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals such as lead, zinc, and copper. Where calcite limestone is uncommon or too costly, dolomite is sometimes used in its place as a flux for the smelting of iron and steel. Large quantities of processed dolomite are used in the production of float glass.

MINERALS SELESTITE Pure Celestine is colorless, but impurities give this mineral a wide range of colors. The most common color is light blue, which is often  caused by irradiation of gold. This light blue tint may be present in a whole specimen, or may only be confined to one area. Celestine is isomorphous with Barite, and may partially replace it. Celestine is the most common mineral containing the element strontium, and is its primary ore. It is a popular mineral among collectors.

MINERALS MAGNESITE Magnesite is a compound of magnesium, its chemical formula is MgC03, and its color varies between white, yellow, grey and brown. It is found in nature as cryptocrystalline and crystalline. It is a tough and complex mineral, and is an alteration product of serpentinite or similar rock types. There are magnesite reserves in Konya, Balıkesir, Bursa, Bilecik, Ankara, Kütahya, Eskişehir and Erzincan.
