The Asnawa iron ore is located near the Iran-Iraq border. Country rocks are traversed by a large number of fractures and veins. The fractures represent as pathways for the migration of hydrothermal solutions.Magnetite exists as dense massive aggregates.Magnetite accompanies by gangue minerals, which consists mainly of hornblende and clinopyroxene. The interrelation between hornblende and magnetite suggests that hornblende is formed contemporaneously with magnetite or a little older.Geochemical analyses show that magnetite has a concentration of Fe2O3 ranging between (90.13- 92.93 %). Nickel,...
