Distribution and characterization of marine iron-rich particles
(Stellenbosch : Stellenbosch University, 2013-12)
ENGLISH ABSTRACT: This thesis investigates questions surrounding the role that iron-rich colloids (nominally sized
between 0.02 μm and 0.2 μm) and particulates (>0.2-0.45 μm) play in the context of the greater ...
Experimental evidence for sulphide magma percolation and evolution : relevant to the chromite bearing reefs of the Bushveld Complex
(Stellenbosch : Stellenbosch University, 2012-03)
ENGLISH ABSTRACT: Pt mineralization within the Bushveld Complex is strikingly focused on the chromitite reefs, despite these horizons being associated with low volumes of base metal sulphide relative to Pt grade. Partitioning ...
Provenance of alluvial diamonds in Southern Africa : a morphological and mineral chemistry study of diamonds and related heavy minerals from the Vaalorange system and the West Coast
(Stellenbosch : Stellenbosch University, 2012-03)
ENGLISH ABSTRACT: The discovery of lucrative diamond deposits along the west coast of Southern Africa
about 1200 kilometres from the Kimberley region during the period 1908 to 1927,
gave rise to a number of different ...
The anatectic history of Archaean metasedimentary granulites from the Ancient Gneiss Complex, Swaziland
(Stellenbosch : Stellenbosch University, 2012-03)
ENGLISH ABSTRACT: This study is an investigation of the anatectic history of high-grade paragneisses from the Ancient
Gneiss Complex (AGC) in Swaziland. The work involved an integrated field, metamorphic,
geochemical, ...
The petrogenesis of the older (> 3.0 Ga) potassic granitoids of eastern Mpumalanga (South Africa) and Swaziland : an investigation of crustal formation processes in the early Earth
(Stellenbosch : Stellenbosch University, 2012-03)
ENGLISH ABSTRACT: Earth’s oldest preserved granitoid crust dates back to the Paleoarchean and consists predominantly
of sodic tonalite-trondhjemite-granodiorite (TTG) granitoids that arose through the partial melting ...
Petrogenesis of S-type granites : the example of the Cape Granite Suite
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH SUMMARY: S-type granite intrusions are extremely common in the continental crust and form
from the partial melting of metasediments. Compositions of S-type granite range
from leucogranite to granodiorite and have ...
The low-pressure partial-melting behaviour of natural boron-bearing metapelites from the Mt Stafford area, Central Australia
(Stellenbosch : University of Stellenbosch, 2011-12)
ENGLISH ABSTRACT: This study has examined the 3 kbar partial melting behaviour of 4 metapelites collected from the highest grade rocks occurring below the anatectic zone of the Mt Stafford area, Arunta Inlier, central ...
The formation of Earth’s early felsic continental crust by water-present eclogite melting
(Stellenbosch : Stellenbosch University, 2013-03)
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 ...
