ENGLISH ABSTRACT: The close spatial and temporal relationship of shear-zones and magmas is commonly interpreted to
indicate positive feedback between magma migration, granitic emplacement and shear-zone-associated
deformation. ...
ENGLISH ABSTRACT: The sodic and leucocratic Tonalite, Trondhjemite and Granodiorite (TTG) granitoid series of
rocks characterise Paleo- to Meso- Archaean felsic continental crust, yet are uncommon in the
post-Archaean ...
ENGLISH ABSTRACT: It is widely accepted that sulphide is the carrier and concentrator of PGEs during magmatic mineralization episodes in the Merensky Reef (MR). PGE concentration peaks and sulphide volume percent peaks are ...
ENGLISH ABSTRACT: The source of the K2O in the K2O-rich ~3.45 Ga felsic intrusive rocks of the H6 unit in the Hooggenoeg Formation of the Onverwacht Group in the Barberton Granite Greenstone Terrain (BGGT) is examined in ...
ENGLISH ABSTRACT: Vaalputs radioactive waste disposal facility is situated in an arid region of Bushmanland currently with evapotranspiration potential that far exceeds precipitation. Dominant soil features in Vaalputs are ...
This study presents a facies outcrop characterization and petrographical analysis
of Unit B of the Permian Laingsburg Formation. Unit B is interpreted as a base-ofslope
system, which represents a strikingly sand-rich ...
