Report on reconnaisance geological mapping of a portion of the Damara Orogen (Area 2015D)
Area 2015D is underlain largely by rocks of Damaran age, most of which are covered by unconsolidated sands. Igneous rocks of Karoo and post-Karoo age intrude the Damaran rocks. The outcrop area of Damaran rocks can be divided into a southern and a northern domain. The southern one consists of high-grade schists and marbles of the Swakop Group intruded by four major types of Damaran granites. The northern domain is separated from the southern one by a major thrust fault, and the rock types found in this domain are low-grade schists, mixtites and marbles. Both domains were intruded by Karoo and post-Karoo granites, quartz-feldspar porphyries and dolerites. Only one phase of deformation, which gave rise to NNE-trending fold axes, has been recognised.
