...Alexander F.M. Kisters; Richard W. Belcher; Reyno Scheepers; Abraham Rozendaal; L. Smith Jordaan; Richard A. Armstrong Abstract The Colenso fault is a major northwest to southeast trending fault zone in the Pan-African Saldania Belt of the Western Cape Province in South Africa that is spatially...

... our observations do not allow us to distinguish whether transpressional strain was sinistral or dextral. Sinistral transpression is considered more likely given the dominantly sinistral strike-slip history on the nearby Colenso Fault and the southward migration of collision along the western margin...

Fault to be located at Northwest Bay, mainly covered by sand. Excellent exposures of km-wide zones of cataclastic and mylonitic deformation in granite outcrops to the immediate north and south of the Colenso fault most likely represent the damage zone around the core of the main fault zone ( e.g

White kaolinitic clay, attaining 70 m in thickness is present in a zone within the Malmesbury Group, up to 1 km wide along the Colenso Fault (see below; Figure 2 ) and is thought to be a result of deep weathering associated with ground...

... by the Colenso fault. Relative age relationships are well preserved amongst the various rock types. In general terms the coarse porphyritic peraluminous (S-type) granites of the batholith represent the oldest phases, followed by more metaluminous medium- and fine-grained granites, ignimbrite flows and finally...

The faults are commonly likened to terrane bounding faults thought to separate two, to possibly three, allochtonous or parautochtonous terranes, namely, from southwest...
