dc.description.abstract The rocks investigated are considered to belong to the Precambrian Crystalline Basement Complex, and have been subjected to metamorphism and folding. Two phases of folding, an f, and a larger regional phase, f2 , have been established. The fold axes of the f, phase vary in trend between north and south-west, while the f2 phase of folding has a fold axis plunging at 70° in an east-south-easterly (108°) direction. There are indications of an earlier (pre-f,) phase of folding, but this was not substantiated. The degree of metamorphism appears to lie within the stability field of the kyanite zone. The rock types include a variety of gneisses, migmatites, associated pegmatites, amphibolites, minor schists, calc silicate nodules and lenses, and a single thin layer of feldspathic quartzite. Meta-intrusive dioritic rocks occur at various localities. They appear at times to have been caught up in the metamorphism and folding and occur as lenses, xenoliths and larger discordant bodies. A number of post-tectonic dolerite dykes have intruded the metamorphics. In a number of instances they are cut by large faults. Absolute ages of the various rocks or major metamorphic events have yet to be established. en_ZA
