Submerged shoreline sequences on the KwaZulu-Natal shelf : a comparison between two morphological settings.
Holocene shoreline sequences and associated shelf stratigraphy are described from a high gradient, high wave energy shelf offshore the central KwaZulu-Natal and northern KwaZulu-Natal coastlines. These are examined using ...
Defining the spectral characteristics of rocks within the Mambulu Complex, Natal Belt, South Africa.
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 ...
Seismic-stratigraphic models for late Pleistocene/Holocene incised valley systems on the Durban continental shelf.
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 ...
The geology and tectonic setting of the Shashe-Foley-Tonota area (Central Motloutse Complex), NE Botswana.
The well-developed NE-SW structural grain of the Shashe, Foley and Tonota (SFT) region is used to separate it from the NW-SE trending structures that characterise the Matsitama belt and adjacent area previously described ...
The geology of the Ngoye granite gneiss formation.
The Ngoye Granite Gneiss Formation is located in the Natal sector of the Proterozoic Namaqua-Natal Mobile Belt, about 10 km southwest of Empangeni. It forms a prominent east-west trending elongate whalebacked massif some ...
Flooding in KwaZulu-Natal : modelling, history and future aspects.
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 ...
Prospectivity analysis of orogenic gold deposits in Saqez-Sardasht Goldfield, Zagros Orogen, Iran.
(Ore Geology Reviews., 2017-03-02)
Diverse deposit-types or mineral systems form by diverse geological processes, so translation of knowledge about the controls of mineralization acquired from the 4D geological modeling into 2D spatial predictor maps is a ...
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 ...
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.
