Abstract:
The area investigated at Magnet Heights covers ten miles of strike of the uppermost six thousand feet of the layered mafic rocks of the Bushveld Complex. A fall of a thousand feet southwards from the Magnet Heights trading store has caused the almost complete "stripping off" of the soil cover to produce excellent rock exposures; a situation unique in this zone of the Bushveld Complex
Monomineralic layered rocks identified are magentitite, anothorsite and pyroxenite. The remaining layered rocks are predominantly gabbroic. In mapping the Mair Magenetitite Seam was taken as a datum line relative to which fur lower seams and 21 upper seams were numbered and mapped. Each of these seams can be recognized by notng its V2OE content, its thickness and its field relationships.
