Geologic and geological assessment of Acid Mine Drainage and heavy metals contamination in the West Rand, Witwatersrand Basin, South Africa
(University of the Western Cape, 2015)Over the years, South Africa has produced over 468 million tons of mine waste yearly, in which gold mining waste accounted for 221 million tons (47%) of all mine waste produced, making it the largest, single source of waste ... -
Geological and hydrgeological characteristics of acid mine drainage from an abandoned coal mine: A case study of Shandi coal mine in Niangziguan spring catchment, Shanxi
(University of Western Cape, 2022)As Shanxi Province is rich in coal resources, the output of raw coal approximately accounts for one quarter of China's production. It is one of the most important energy and heavy chemical bases and plays a significant ... -
Geological modeling of the offshore Orange Basin, west coast of South Africa
(UWC, 2009)Separation between the South American and African plate’s occurred along the present day Atlantic margin during the Middle to Late Jurassic leading to the formation of a passive margin along the west coast of Southern ... -
Geological modelling for carbon storage opportunities in the Orange Basin South Africa
(University of the Western Cape, 2019)This study investigates the viability of the sedimentary deposits in the Northern Orange basin for carbon storage and sequestration. A combination of geological modelling, petrographic and geochemical techniques are used ... -
Geology, geochemistry and Sr-Nd isotope analysis of the Vredenburg batholith and Cape Columbine granites
(University of the Western Cape, 2018)The late− to post−collisional Cape Granite Suite (CGS) located in the southwest of South Africa is comprised of S−, I−, and A−type granites, mafic intrusives, and volcanic flows. The CGS is interpreted to have formed ... -
Geology, geochemistry and Sr-Nd isotope analysis of the Vredenburg Batholith and Cape Columbine Granites Paternoster/Vredenburg, South Africa: Implications on their petrogenesis, tectonic setting, and sources.
(University of the Western Cape, 2018)The late- to post-collisional Cape Granite Suite (CGS) located in the southwest of South Africa is comprised of S-, I-, and A-type granites, mafic intrusives, and volcanic flows. The CGS is interpreted to have formed ... -
Geometry and geobody extraction of a submarine channel complex in the Sable Field, Bredasdorp Basin
(University of the Western Cape, 2015)The Sable Field constitutes a Basin Floor Channel (BFC) complex (E-BD reservoir) and a Basin Floor Fan (BFF) complex (E-CE reservoir). The reservoir sands were deposited during early-drift sedimentation in the Bredasdorp ... -
Geomorphic analysis of river character and behaviour in three semi-arid, mountainous catchments in the Eastern Cape, South Africa
(University of Western Cape, 2019)The analysis of what controls why rivers are the way they are, and how and why they change is crucial in predicting river dynamics and deriving classification systems that can assist management. A variety of factors control ... -
Geomorphological controls on pool formation and pool persistence in non-perennial river systems
(University of the Western Cape, 2020)Globally climate variability and anthropogenic effects are causing more perennial rivers to become non-perennial rivers. Non-perennial rivers are distinguished by their isolated pools which serve as refugia for aquatic ... -
Giant Magnetocaloric effect and Magnetic Properties of selected Rare-Earth compounds
(University of the Western Cape, 2021)Rare-earth (RE) compounds have been an attractive subject, based on the unique electronic structures of the rare-earth elements. In particular, the RETX (RE = rare-earth, T = 3d/4d/5d, transition metals, and X = p – block ... -
GIS and remote sensing-based integrated modelling of climate and land use change impacts on groundwater quality: Cape Flats Aquifer, South Africa
(University of Western Cape, 2021)The need to ensure groundwater security is vital, particularly in urban areas. Assessing the impact of land use and climate variables on groundwater quality can help improve sustainable management. The vulnerability mapping ... -
A global revision of the nongeniculate coralling algal genere Porolithon Foslie (defunct) and Hydrolithon Foslie (Corallinales, Rhodophyta)
(University of the Western Cape, 2005)The purpose of this thesis was to provide a revision and characterization of the species of nongeniculate coralline algae previously ascribed to the now defunct genus Porolithon; to provide a modern account of selected ... -
Gold nanoparticulate modified thioglycolic acid (tga) phenotype nanobiosensor for tuberculosis drugs
(University of the Western Cape, 2022)Tuberculosis (TB) carries on being a major global health issue and it is responsible for 1.5 million disease-related mortality in 2020, according to the World Health organisation (WHO). One of the major causes of death ... -
Granivores as ecosystem regulators of woody plant increasers in semi-arid Savannas of the Lowveld, South Africa
(University of the Western Cape, 2006)In recent years, a global trend of increasing woody vegetation densities in semi-arid savanna habitats has been recorded, commonly described in South Africa as 'bush encroachment'. The shrubs and trees that do this ... -
Graphenated electrode protocol for electrochemical nanosensing of 17β- estradiol as an environmental estrogeneous endocrine disruptor
(University of the Western Cape, 2016)17β-Estradiol can be defined as an endocrine disruptor chemical with estrogenic activity, which can bind to the estrogen receptor in the body and potentially alter the normal physiological function of the endocrine ... -
Graphenated organic nanoparticles immunosensors for the detection of TB biomarkers
(University of the Western Cape, 2017)Pulmonary Tuberculosis (TB) a disease second to HIV/AIDS is a global health problem that arises in two states; as an active state and as a latent state. Diagnosis of active TB is tedious and requires expensive procedures ... -
