Magister Scientiae - MSc (Earth Science) / The Kliprand dome is a poorly investigated structure located in the central part of the high grade
Garies Terrane of the western Namaqua Sector (NS) of the Namaqua-Natal Metamorphic Province
(NNMP). This structure is host to a diverse variety of supracrustal rocks comprising predominantly
metapelites and quartzites of the Kamiesberg Group, the streaky augen gneiss, an enigmatic pink
gneiss (official name the Lekkerdrink Gneiss) of which the origin is obscure, the metasomatic
charnockites along with the pre- to syn-tectonic two-pyroxene granulites (or gabbro-norite) of the
Oorkraal Suite. Large bodies of garnet-quartz-feldspar granite, believed to be the products of
dehydration melting during peak metamorphism, are referred to as the Ibequas Granite. The
transformation of these sediments and volcanic rocks into gneisses and migmatitites was
accomplished by intense regional metamorphism during the 1.2-1.0 Ga Namaqua Orogeny. In order
to unravel the tectonic evolution of the Kliprand dome, a structural, lithogeochemical, isotopic and
geochronological study was undertaken.
