Abstract

Hogbomite analysing 59.94% Al2O3, 6.01% TiO2, 0.21% V2O3, 21.02%, FeO, 0.14%, MnO, 9.66%, MgO and 1.06% ZnO occurs as a widely distributed mineral phase in the vanadiferrous Fe-Ti ore deposits of Madangere area. It occurs in well developed prismatic crystals, and small scales/rods/patches enclosed in magnetite ore grains, and locally as rims to spinel. While the coarse prisms of hogbomite bear characters of primary mineral phase, the small scales/rods/patches appear to represent exsolved phase and that forming rims to spinel is derived by the alteration of spinel. The mineral is reported for the first time from India.
