A dissertation submitted to the Faculty of Science, University of the
Witwatersrand, Johannesburg, in fulfilment of the requirements for the
degree of Master of Science. / The Sterkspruit Intrusion, in the south-western portion of the Barberton
greenstone belt, is a sill-like body containing rocks of gabbroic to dioritic
composition, It is hosted by a sequence of komatilitic basalts and komatilites of
the Lower Onverwacht Group. The intrusion is considered unique in this area in
that it lacks ultramafic components and has no affinities with the surrounding
mafic- to- ultramafic lavas, The gabbroic suite also contains an unusual
abundance of quartz, and the chill margin shows an evolved quartz-normative,
tholelitic parental magma. ( Abbreviation abstract ) / AC2017
