Abstract
Heavy mineral concentrates from stream sediments in the Anka schist belt of NW Nigeria were examined for their ilmenite, magnetite and gold contents. A spatial relationship was found between samples with high ilmenite: magnetite ratios and gold anomalies. The ilmenite may have formed at relatively low temperatures from ulvo-spinel-magnetite exsolution at the same stage of gold mobilization.
