Overview of Mining in Markazi province
Due to its geological structure and its location in the Sanandaj-Sirjan zone, Markazi province is one of the most mineral-rich districts in Iran. Malayer–Isfahan lead and zinc belt is located in the province, which has led to the formation of large mines of lead and zinc, such as the Emarat, the Hossein Abad and the Lakan. In large parts of this province, marl calcareous shales are invaded by granitic, granodiorite and tonalite igneous masses and some important reserves of base and precious metals are formed such as iron in the Shams Abad and the Kooh Palang, manganese and copper in the Saveh, Tungsten in the Nezam Abad and Tin, molybdenum and gold in the Astaneh. There are large reserves of decorative stones such as quartz, marble, travertine, and construction materials such as gypsum, lime, and sand. Silica minerals, fluorine, barite, and industrial minerals, which provide the primary sources for the glass industry, tiles, and industrial ceramics, are found in the province. Markazi province is also producing large quantities of sodium sulfate as the main ingredient of all detergents in Iran.
