(Stellenbosch : Stellenbosch University, 2001-12)ENGLISH ABSTRACT: This study focussed on the comparison of accessory mineral chemistry and paragenesis in the S-, I- and A-type granites of the Cape Granite Suite. The objective of the study was to use differences in ... -
Application of hydrochemistry and residence time constraints to distinguish groundwater systems in the Karoo Basin prior to shale-gas exploration
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: The possibility of shale-gas development in the semi-arid Karoo Basin, South Africa has created the need to develop a hydrochemical baseline for deep Karoo groundwater. However, it is uncertain how the ... -
Aspects of the filament activity within the Benguela upwelling system
(Stellenbosch : Stellenbosch University, 1988-12)ENGLISH ABSTRACT: The Benguela upwelling system off southern and south western Africa is a zone of strong and extensive upwelling. Owing to the greater fIsh numbers found along the front between the upwelling and South ... -
Assessment of GIS-interpolation techniques for groundwater evaluation : a case study of the Sandveld, Western Cape, South Africa
(Stellenbosch : University of Stellenbosch, 2004-12)ENGLISH ABSTRACT: The Sandveld, a potato growing area of the Western Cape is subject to significant groundwater abstraction for both municipal and agriculture purposes. The climate is arid and sensitive and important ... -
Basinfill of The Permian Tanqua depocentre, SW Karoo basin, South Africa
(Stellenbosch : Stellenbosch University, 2012-03)ENGLISH ABSTRACT: Basin subsidence analysis, employing the backstripping method, indicates that fundamentally two different basin-generating mechanisms controlled Tanqua depocentre development in SW Karoo Basin. The ... -
The biogeochemistry of bioactive trace elements cadmium and cobalt in the Southern Ocean, Atlantic Sector
(Stellenbosch : Stellenbosch University, 2017-03)ENGLISH ABSTRACT: The biogeochemical cycling of the bio-active dissolved trace metals cadmium (DCd) and cobalt (DCo), are reported on a meridional transect of the Southern Atlantic, spanning 36°S to 68°S. Seawater samples ... -
The cenozoic stratigraphy and associated heavy mineral palaeo-placer deposit on Geelwal Karoo : West Coast, South Africa
(Stellenbosch : Stellenbosch University, 2005-03)ENGLISH ABSTRACT: The farm Geelwal Karoo is situated some 16km north of the Olifants River mouth on the West Coast of South Africa and hosts fluvial, marine and aeolian deposits of post-Gondwana age. The oldest basal ... -
Characterising and mapping of wind transported sediment associated with opencast gypsum mining
(Stellenbosch : Stellenbosch University, 2008-03)This study aims to provide a practical tool for the prediction and management of dust generated by the activities of an opencast mining operation. The study was conducted on opencast gypsum mines in the semi-arid environment ... -
A comparison between diamictites at the Witteberg-Dwyka contact in southern South Africa
(Stellenbosch : Stellenbosch University, 2015-04)ENGLISH ABSTRACT: Diamictites are sedimentary deposits that originate from a number of different environments, the most common being associated with a glacial environment. Although this association is not, in all cases ... -
Contemporaneous glacial folding in the Table Mountain group, Western Cape
(Stellenbosch : Stellenbosch University, 1970) -
Deep groundwater characterisation and recharge estimation in the Verlorenvlei catchment
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT: Secondary aquifers are a primary source of water in many semi-arid regions, and understanding groundwater recharge is necessary for the effective management of this resource. The Chloride Mass Balance ... -
Development and implementation of a flow injection analyser with chemiluminescence for detection of sub-nanomolar Fe in seawater
(Stellenbosch : Stellenbosch University, 2014-12)ENGLISH ABSTRACT: Iron is an essential micronutrient for all phytoplankton and is found in seawater at picomolar-level concentrations. For the first time in South Africa, a technique that utilizes a flow injection analyser ... -
Disequilibrium melting of plagioclase during biotite fluid-absent anatexis of metapelites in the South Marginal Zone of the Limpopo belt, South Africa
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: This study investigated the behaviour of plagioclase during fluid-absent biotite melting in a metapelitic source from which peraluminous granite magma had segregated. The study focused on the Bandelierkop ... -
Distribution, mineralogy and provenance of heavy minerals in cainozoic sediments of the Namaqua Mines area, West Coast of South Africa
(Stellenbosch : Stellenbosch University, 1999-12)ENGLISH ABSTRACT: In view of the recent developments in heavy mineral exploration, a sampling programme was initiated to determine the economic potential of heavy mineral occurrences in the Kleinzee mining area. The ... -
The evaluation of whole-rock and partial leach geochemical exploration techniques applied to the exploration for tanzanite deposits : Merelani, North-Eastern Tanzania
(Stellenbosch : Stellenbosch University, 2007-12)ENGLISH ABSTRACT: The aim of the study is to ascertain whether geochemical exploration techniques can be used in the search for tanzanite deposits in the Merelani area, NE Tanzania. Previous studies have successfully ... -
An experimental investigation into the ‘fate’ of entrained peritectic minerals in I-type granite magmas intruded at below 2kbar.
(Stellenbosch : Stellenbosch University, 2016-04)ENGLISH ABSTRACT: Entrainment of a peritectic mineral assemblage, formed through the incongruent melting of biotite and hornblende in a source of intermediate composition, has been proposed to account for the fact that ... -
An experimental investigation of the “fate” of entrained peritectic minerals during adiabatic ascent of S-type granite magmas
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT: S-type granites generally display a wide range of trace and major element compositional variation, from tonalitic to leucogranitic compositions. A substantial volume of past research has investigated the ... -
