Abstract provided by author:
It has been found possible to differentiate between Kamtsas and Damara quartzites on petrological grounds. Further, it is concluded that the bulk of Hakos carbonate rocks originated as dolomites and have subsequently been dedolomitized to a greater or lesser extent
The area contains both ortho- and para-amphibolites, as well as one occurrence of intrusive granite
Evidence is given for at least three periods of deformation. It is considered that, if the Kosib Formation was involved in a pre-Damara Orogenic episode, later folding must have been co-axial with this
Sedimentation and metamorphism are treated in broad outline. There appears to have been a deepening of the basin of deposition from Nosib to Damara tines. Cyclicity in sedimentation is evidenced by lithological associations in the Damara strata. The entire area falls into the greenschist facies of regional metamorphism
Superficial deposits include river gravel and silt, quartzite- and vein quartz-rubble, calcrete and Kalahari sand
The economic geology is described with special reference to the widespread copper mineralisation
