AMIS0346 Fe 44.3% Ti 15.0% V 0.3% Magnetite Bushveld South Africa
Origin of Material: The material for this CRM was provided by Tivani (Pty) Ltd. from an exploration project in the late-Archean Rooiwater Complex situated in the eastern sector of the Murchison Range 10km north of Gravelotte in the Limpopo Province of South Africa. The material was collected off stockpiles resulting from exploration development into vanadium-bearing, Ti-magnetite rich layers that are present within the upper portion of the mafic Novengilla Gabbro Suite.
Mineral and Chemical Composition: The two major titaniferous magnetite layers are relatively pure, containing minor chlorite towards the edges. The upper layer contains minor appetite. The ore comprises smaller ilmenite crystals located interstitially between larger Ti-magnetite crystals.
