Of iron, formed the iron ore (hematite magnetite) in the metamorphic basement rocks. As a new target area, the region has a powerful potential. The uplifting of the metamorphic massif and related post metamorphic tectonics (possibly in Neo tectonic period) gave way the prominent channels for emplacement of hydrothermal fluids in the area.

Magnetite Ore, Magnetite Iron Ore, Iron Ore Mining Process

Magnetite ore often occurs in metamorphic rocks, which formed from ferruginous sediments in both regional and contact metamorphic settings. It is commonly formed by the reduction of hematite and ferric hydroxide minerals in these rocks. Banded Precambrian iron formations commonly contain magnetite ore.
