Fluid and deformation induced partial melting and melt escape in low-temperature granulite-facies metasediments, Damara Belt, Namibia.
(Stellenbosch : University of Stellenbosch, 2009-03)
Fluid-present partial melting has generally been regarded a poor candidate for effecting crustal differentiation. In this study I report on anatectic metasediments from the Pan-African Damara Belt in Namibia that have ...
Tectonostratigraphic evolution of the Swartland region and aspects of orogenic lode-gold mineralisation in the Pan-African Saldania Belt, Western Cape, South Africa
(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: The Swartland region in the western Cape, South Africa, covers approximately 5000 km2 and forms part of the Pan-African Saldania Belt that represents the southernmost extremity of the Pan-African ...
The effect of winery wastewater irrigation on the properties of selected soils from the South African wine region
(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 ...
The geology and petrology of the Marble Delta
(Stellenbosch : Stellenbosch University, 1973-02)
The Marble Delta is an area of approximately 40 sq. km in Natal (30°22' Long., 30°40' Lat.), occupied by Precambrian marble and associated granites. The deeply dissected country was geologically mapped on a scale of I : 6 ...
Chemostratigraphic trends and provenance of the Permian Tanqua and Laingsburg depocentres, southwestern Karoo Basin, South Africa
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: Foreland basins commonly fill with sediment derived from the adjacent fold/thrust belt, providing a relatively simple source-to-basin configuration. However, that is not true for the early southwestern ...
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 ...
The metamorphic and anatectic history of Archaean metapelitic granulites from the South Marginal Zone, Limpopo Belt, South Africa.
(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
(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 ...
Die geologie van 'n gebied in Noord-Oos Transvaal met spesiale verwysing na die verspreiding en petrografie van die rotssoorte van die Palabora-stollings-kompleks
(Stellenbosch : Stellenbosch University, 1948-12)
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
(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 ...
