The Ahlmannryggen group, western Dronning Maud Land, Antarctica.
(2001)The Mesoproterozoic Ritscherflya Supergroup forms an extensive volcano-sedimentary cover succession on the Archaean Grunehogna Province of western Dromring Maud Land, Antarctica. The oldest:, predominantly sedimentary ... -
Alkaline intrusives from the Tugela terrane, Natal metamorphic province.
(1991)Three gneissose alkaline granitoid intrusives at Ngoye, Bulls Run and Wangu are described. They are located within the Nkomo Nappe of the Tugela Terrane, near the northern margin of the Natal Metamorphic Province. The ... -
Aspects of Karroo vulcanicity in the Komatipoort area Lebombo.
(1979)The petrology, mineralogy and geochemistry of the Karroo-age basaltic and rhyodacitic volcanics present in the Lebombo Belt near Komatipoort, Eastern Transvaal, Republic of South Africa are described. The volcanics ... -
Aspects of the engineering geology of Maputo City, Mozambique.
(2011)The geological formations of Maputo City, which are mainly unconsolidated materials with soil like properties, are described in terms of their engineering geological and geotechnical characteristics with relevance to ... -
Aspects of the geology and geochemistry of the proterozoic rocks of the Valley of a Thousand Hills, KwaZulu-Natal.
(1999)A regional field and geochemical study has allowed the identification of three primary units within the Proterozoic basement of the Valley of a Thousand Hills. The Nagle Dam Formation incorporates several chemically ... -
The assessment of groundwater quality in rural communities : two case studies from KwaZulu-Natal.
(1998)The health and life expectancy of populations in developing countries is largely determined by the availability of good quality drinking water. Boreholes and springs generally provide water of better microbiological ... -
Assessment of the permeability of Vryheid formation sediments.
(1994)Permeability is that physical property of a porous medium that controls the flow of fluids through that medium. The flow of methane and water may be induced by the excavation of a mine opening in methane-bearing strata. ... -
The bathymetry, sedimentology and seismic stratigraphy of Lake Sibaya- Northern KwaZulu-Natal.
(1998)The morphology of Lake Sibaya is a product of an ancient fluvial system that drained a coastal landscape dominated by aeolian processes. The sedimentary processes within the lake are driven by wind generated currents. ... -
Biodiversity conservation and rural livelihoods : a comparative study of selected conservation approaches in Zimbabwe.
(2014)Historically, protected areas have operated as islands of biodiversity conservation in isolation from nearby communities. There is, however, a growing consensus that for protected areas to be more effective in conserving ... -
Catchment hydrological modelling using ArcSWAT : a study of the Ingula pumped storage scheme (IPSS) catchments, South Africa.
(2017)Abstract available in PDF file. -
Characterisation of geotechnical, geochemical and metallurgical properties for mine-to-mill optimisation at Sandsloot open pit platinum mine, South Africa
(2008)Sandsloot open pit mine extracts platinum, copper and nickel from the Platreef orebody in the Northern Limb of the Bushveld Complex. At present, it is the world's largest open pit platinum mine, but it is one of the smaller ... -
A combined sedimentological-mineralogical study of sediment-hosted gold and uranium mineralization at Denny Dalton, Pongola Supergroup, South Africa.
(2009)The ~2.98 - 2.87 Ga Pongola Supergroup in South Africa is subdivided into the lower volcano-sedimentary Nsuze Group, and the upper sedimentary Mozaan Group, the latter comprising a several kilometres thick succession of ... -
Conventional hydrogeological, hydrochemical and environmental isotope study of the Sandspruit River Catchment, Berg River Basin, South Africa.
(2012)The Sandspruit River catchment, found within the heart of the Swartland region is infamous for wheat and wine production. Variable groundwater quality and low productivity is encountered within the folded and fractured ... -
Defining the spectral characteristics of rocks within the Mambulu Complex, Natal Belt, South Africa.
(2012)Field and laboratory spectroscopy are sub-fields of remote sensing, where the radiometric data of materials are individually measured either where the materials occur in situ or in a controlled laboratory environment. Both ... -
The development and application of a 3D geotechnical model for mining optimisation Sandsloot open pit platinum mine South Africa.
(2003)Detailed geological knowledge is often a major unknown factor in open pit mining and design, and therefore poses a significant risk in the mining venture. As the knowledge of the geology improves so the risk of unforeseen ... -
Developments in GIS-based mineral prospectivity mapping : An overview.
(Bureau de Recherches Géologiques et Minières (French Geological Survey), 2017-10)This keynote presentation provides an overview of the developments in GIS-based mineral prospectivity mapping during the past 30–40 years or so. -
The efficiency of logistic function and prediction-area plot in prospectivity analysis of mineral deposits.
(Bureau de Recherches Géologiques et Minières (French Geological Survey)., 2017-10)In this work, we present logistic-based mineral prospectivity mapping (MPM) methods concerning with assigning weights of exploration indicators, without contribution of training sites as in supervised MPM and without ... -
Evolution of the northern KwaZulu-Natal coastal dune cordon : evidence from the fine-grained sediment fraction.
(2001)Abstract available in PDF file. -
Flooding in KwaZulu-Natal : modelling, history and future aspects.
(2014)The current state of flood modelling relies on statistical techniques revolving around either river or rainfall data that are used to produce an estimated flood return period (e.g. 1:100 year). These tend to ignore 1) the ... -
