The effect of winery wastewater irrigation on the properties of selected soils from the South African wine region

Mulidzi, Azwimbavhi Reckson (Stellenbosch : Stellenbosch University, 2016-12)

ENGLISH ABSTRACT: Due to an increase in wine production as well as an intensification of environmental legislation in South Africa, the need for guidelines for sustainable management of winery wastewater has increased. To ...

Distribution and characterization of marine iron-rich particles

Von Der Heyden, Bjorn Phillip (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 ...

The metamorphic and anatectic history of Archaean metapelitic granulites from the South Marginal Zone, Limpopo Belt, South Africa.

Nicoli, Gautier (Stellenbosch : Stellenbosch University, 2015-04)

ENGLISH ABSTRACT: Anatexis is the first step in granite genesis. Partial melting in the lower crust may produce leucoratic features of unusual chemical compositions, very different from the final products of crustal ...

Experimental evidence for sulphide magma percolation and evolution : relevant to the chromite bearing reefs of the Bushveld Complex

Koegelenberg, Corne (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 ...

Structure and evolution of basin and petroleum systems within a transformrelated passive margin setting : data-based insights from crust-scale 3D modelling of the Western Bredasdorp Basin, offshore South Africa

Sonibare, Wasiu Adedayo (Stellenbosch : Stellenbosch UniversityStellenbosch University, 2015-04)

ENGLISH ABSTRACT: This study investigates the crustal structure, and assesses the qualitative and quantitative impacts of crust-mantle dynamics on subsidence pattern, past and present-day thermal field and petroleum system ...

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

Van der Westhuizen, Asriel (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

Taylor, Jeanne (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

Sanchez-Garrido, Cynthia J. M. G. (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 ...

Evolution of the continental crust and significance of the zircon record, a case study from the French Massif Central.

Couzinie, Simon Gwenael (Stellenbosch : Stellenbosch University, 2018-03)

ENGLISH ABSTRACT: The formation of the continental crust is a major consequence of Earth di erentiation. Recent advances on this topic bene ted from improvements of analytical techniques enabling in situ measurements of ...

Petrogenesis of S-type granites : the example of the Cape Granite Suite

Villaros, Arnaud (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 ...
