Marine geology of the East London continental shelf.
(2017)This dissertation examines the marine geology of the continental shelf offshore East London, on the east coast of South Africa. High-resolution seismic, multibeam bathymetric and backscatter tools are employed to reveal ... -
Mechanisms of sill and dyke intrusion.
(1994)Mechanisms of sill and dyke intrusion require an understanding of fracture growth,stress distributions and intensities, dilation,intrusion rates, hydraulic pressure,host-rock effects,en echelon fracture arrays,and flow ... -
The Mgeni Estuary pre- and post Inanda Dam Estuarine dynamics.
(2009)The funnel-shaped Mgeni Estuary, at the mouth of the fourth largest river along the KwaZulu- Natal coast, discharges into the Indian Ocean in the northern suburbs of Durban. This system is under considerable anthropogenic ... -
Mineralogy and geochemistry of clay sediments in pans of the Northern Cape Province, South Africa.
(2010)This thesis reports the results of a mineralogical and geochemical study of pans situated in the Northern Cape Province with special emphasis on the clay minerals. From east to west the depth and size of the pans increase ... -
Mineralogy and geochemistry of detrital rutile from the Sibaya Foundation, KwaZulu-Natal.
(2002)Rutile, although not a major component of detrital heavy mineral deposits, is a valuable source of titanium oxide. Theoretically rutile is pure titanium dioxide (TiO2) and should form white or colourless tetragonal crystals ... -
The mineralogy and related geology of the Albert Silver Mine, Bronkhorstspruit, Transvaal
(1970)The Albert Silver mine is situated on the farm Roodepoortjie, 32 kilometres north of Brorikhorstspruit in the Transvaal. The deposit forms the largest of a number of sub-parallel quartzhematite lodes accompanied by sulphide ... -
The mineralogy, petrology and PGE geochemistry of the UG2 cyclic unit at Lebowa Platinum mine (ATOK), North-Eastern Bushveld complex.
(2008)This project is an investigation of the UG2 cyclic unit of the Upper Critical Zone at Lebowa (Atok) -
Nearshore morphological changes and their relation to wave-induced forcing at Isipingo embayment, KwaZulu-Natal.
(2017)The nearshore zone is one of the most active sedimentary environments on the continental shelf, frequently impacted by energetic wave conditions and storm–generated waves and flows. Despite its proximity to the beach and ... -
Palaeoenvironments of the Estcourt formation (Beaufort Group), KwaZulu-Natal.
(1997)At present the Karoo Basin covers approximately 20 000 km2. It is a large intracratonic basin which, from Carboniferous to Jurassic times, was infilled with a succession of sediments ranging from glacial deposits to those ... -
The petrology and geochemistry of the karoo sequence basaltic rocks in the Natal Drakensberg at Sani Pass.
(1992)The Sani Pass in the Natal Drakensberg is situated in the north-eastern sector of the Lesotho Highlands which forms a major Karoo-age basaltic massif in the Karoo Igneous Province. The volcanic section exposed in the ... -
The petrology and geochemistry of the Merensky reef in the Rustenburg area.
(1994)Four Merensky reef underground exposures of different reef thickness, representative of the lithological variations exposed in mining, have been drilled and mapped. The relationship of the Merensky reef to the underlying ... -
The petrology, geochemistry and classification of the Bien Venue massive sulphide deposit, Barberton mountain land.
(1990)The Bien Venue massive sulphide deposit is associated with a felsic volcanic succession developed in the north-eastern part of the Barberton Greenstone Belt, Eastern Transvaal. The deposit is situated 8km east-north-east ... -
The physical volcanology and geochemistry of the Nsuze group, Pongola supergroup, of northern KwaZulu-Natal and southeastern Mpumalanga.
(2003)The Nsuze Group forms the lower, predominantly volcanic succession of the Pongola Supergroup. The 2.9Ga Nsuze Group outcrops in southeastern Mpumalanga, northern KwaZulu-Natal and Swaziland. The volcanic rocks ... -
Richards Bay zircon.
(1992)Zircon from the zircon concentrate of Richards Bay Minerals was investigated with a view to understanding the morphology and provenance. The obsevations were applied to the reduction of uranium, thorium and other trace ... -
Rock mass rating and slope stability analysis of quarry faces within the dywka [i.e. dwyka] tillite of KwaZulu-Natal.
(2002)Dwyka tillite quarries in the Province of KwaZulu-Natal have shown remarkable stable slopes faces even though some of them were quarried over 30 years ago. This can be attributed to their resistance to weathering, the ... -
Sedimentology, stratigraphy and geological history of part of the northern KwaZulu-Natal coastal dune cordon, South Africa.
(1999)The northern KwaZulu-Natal coast is backed by a continuous aeolian dune cordon that rises in places, to a height of more than 100 metres and a width of 2 kilometres. This MSc thesis documents the geomorphology of the ... -
Seismic stratigraphy of the northern KwaZulu-Natal upper continental margin.
(1998)This study presents the interpretation of Edo-Western and Sparker seismic geophysical data acquired on the northern KwaZulu-Natal upper continental margin by various organisations since 1981. Five seismic sequences are ... -
Seismic, geochemical and sedimentological characteristics of storm deposits from the Durban continental shelf, South Africa.
(2015)The Durban shelf is a wave-dominated, high energy setting, characterised by submerged shorelines at depths of ~60 m, backed to landward by low-relief backbarrier depressions. The exposure at the seafloor of a back-barrier/lagoon ... -
Seismic-stratigraphic models for late Pleistocene/Holocene incised valley systems on the Durban continental shelf.
(2013)This dissertation examines the Durban continental shelf of the east coast of South Africa from a seismic and sequence stratigraphic perspective. High resolution seismic data reveal eleven seismic Units (A-K) offshore ...
