“…Vilijoen et Scoon (1985) définissent 4 types de pegmatites riches en fer à caractère discordant : 1-les cheminées ultramafiques riches en platine "platiniferous ultramafic pipes" ; 2-les pegmatites riches en fer à caractère discordant ; 3-les cheminées de dunite magnésiennes pauvres en platine ; 4-d'autres corps pegmatitiques (cheminées de sulfures de nickel ; anorthosite pegmatitique ; pegmatite riche en vermiculite). Pour l'intérêt de notre étude, nous allons nous contenter des types 2.…”

“…Oxide mineralization occurs as disseminated (15 to 30%), semimassive (30 to 70%), and massive (>70%) and is composed of ilmenite and/or magnetite; in some cases, the magnetite along the western contact can be enriched in vanadium (3,000 to 8,000 ppm V). OUIs have many similarities to the discordant, iron-rich, pegmatitic ultramafic bodies of the Bushveld Complex (Wagner, 1929;Cameron and Desborough, 1964;Schiffries, 1982;Scoon, 1987;Stumpfl and Rucklidge, 1982;Viljoen and Scoon, 1985;Schiffries and Skinner, 1987;Rudashevsky et al, 1992), the Stillwater Complex (Volborth and Housley, 1984;McCallum, 1984, 1985;Nicholson and Lipin, 1985), and the Rio Jacare Intrusion of Brazil (Sá et al, 1993).…”

“…The presence of either fluid phases or volatile-rich silicate liquids in layered intrusions is evidenced by hydrous minerals, graphite and pegmatoidal textures. Mobilization of such fluids has been implicated in the formation of ultramafic pegmatites in the Bushveld and other layered complexes (e.g., Viljoen and Scoon 1985;McBirney and Sonnenthal 1990;McBirney and Naslund 1990;Mogessie et al 1991;Scoon and Mitchell 1994).…”
