Vanadium Bearing Titaniferous Magnetite Deposits of Karnataka, India

The vanadium bearing titaniferous magnetite deposits of Karnataka occur within gabbro-anorthosite members, spatially associated with the ultramafic rocks emplaced in the platformal miogeosynclinal regions of the Dharwar schist belts. They are generally conformable, syngenetic magmatic deposits, although instances of magmatic injection are known. Vanadium occurs in magnetite lattice substituting for ferric iron. The vanadium bearing titaniferous magnetites often carry copper and iron sulphide mineralization. The association of titaniferous magnetite with the ultramafic-mafic suite and their tectonic setting suggest, that the ultramafic-mafic sequence of rocks of Dharwar greenstone belts are probably not alpine, but compare better with concentric complexes.
