The Platreef of the Bushveld Complex, South Africa: a new hypothesis of multiple, non-sequential magma replenishment based on observations at the Akanani project, north-west Of Mokopane

BY ROGER N. SCOON AND ANDREW A. MITCHELL. Detailed logging of relatively deep drill-core from the Akanani Project, in the northern limb of the Bushveld Complex, South Africa, has afforded new perspectives on the Platreef and its origins. In line with most recent studies, we believe the mineralization to be …

The principal geological features of The Mooihoek platiniferous dunite pipe, eastern limb of the Bushveld Complex, and similarities with replaced Merensky Reef at The Amandelbult Mine, South Africa

BY ROGER N. SCOON AND ANDREW A. MITCHELL. The four platiniferous dunite pipes in the eastern limb of the Bushveld Complex, South Africa, differ sufficiently from one another to warrant investigation as separate entities, but despite their differences they are similar enough to enable us to establish a holistic genetic …

A Multi-Stage Orthomagmatic and Partial Melting hypothesis for the Driekop platiniferous dunite pipe, eastern limb of the Bushveld Complex

BY ROGER N. SCOON AND ANDREW A. MITCHELL. The occurrence of platiniferous dunite pipes is restricted to four localities in the eastern limb of the Bushveld Complex. They comprise wholly discordant bodies aligned perpendicular to the regional layering, and reveal a complex internal zonation.They remain poorly understood, despite a number …

The platiniferous dunite pipes in the eastern limb of the Bushveld Complex: Review and comparison with unmineralized discordant ultramafic bodies

ROGER N. SCOON AND ANDREW A. MITCHELL. The platiniferous dunite pipes of the Bushveld Complex are subvertical, cylindrical bodies (diameters of 180-500m) that crosscut the layered cumulates in the central sector of the eastern limb more or less at right angles. They are restricted to four localities. The Driekop and …

Petrogenesis of Discordant Magnesian Dunite Pipes from the Central Sector of the Eastern Bushveld Complex with Emphasis on the Winnaarshoek Pipe and Disruption of the Merensky Reef

ROGER N. SCOON AND ANDREW A. MITCHELL. Discordant ultramafic bodies are a significant feature of the Bushveld Complex, South Africa. Many of these bodies form subvertical, cylindrical pipes oriented more or less at right angles to gently dipping layered rocks. Three main types of discordant ultramafic body have been identified: …
