Geochemical evolution in defunct gold mine tailings and modelling of seepage water quality: an investigation of a typical tailings storage facility in the East Rand, Johannesburg, South Africa
(University of the Free State, 2022)The geochemical evolution in a defunct tailings dam was investigated in the East Rand Basin of the Witwatersrand. The research aimed to geochemically characterise the tailings, quantify oxygen infiltration into the ... -
A multi-isotope (S-Sr-Nd) investigation of the Flatreef, Northern Limb, Bushveld Complex: Petrogenetic implications and comparison with the Merensky Reef
(University of the Free State, 2022)Historically, research on the Bushveld Complex (BC) in the northern limb mainly focused on the near surface Platreef. The Platreef is well-known for being complicated and erratic due to significant degrees of country rock ... -
Geochemical and mineralogical characterization of the lithological units of the geodehoop colliery in the Witbank coalfield to fathom the source and the receptor of metals in the riet-olifants catchment, South Africa
(University of the Free State, 2022)The study aims to understand the element deportment's geochemical characteristics from the source, pathway and receptor realm in the Riet-Olifants catchment (ROC) drainage system. The ROC is part of the Olifants primary ... -
The relationship between mineralisation and structure in the Pilgrim's Rest - Sabie gold-field
(University of the Free State, 1967-11)The area that was investigated, covers the metallogenetic province of the Sabie-Pilgrim's Rest Gold-field in the Eastern Transvaal. The geological formations include the Basement Granite, Godwan Formation, Wolkberg Formation, ... -
The geology of the acid phase of the Bushveld complex, north of Pretoria: a geochemical/statistical approach
(University of the Free State, 1980-12)A petrographical and geochemical study of the acid phase of the Bushveld Complex, north of Pretoria, was undertaken with the aim to identify the different rock units, to determine their interrelationships and to classify the ... -
The geology of the Springbok Flats
(University of the Free State, 2012)The Springbok Flats constitutes an extensive tract of generally flat country extending from south of Bela Bela north-eastwards to Zebediela Location. This area is located within 28˚00´ and 29˚30´ east and 24˚15´ and 25˚30´ ... -
Composition and evolution of the proterozoic Vioolsdrif batholith (including the Orange River group), Northern Cape province, South Africa
(University of the Free State, 2011-12)English: The Vioolsdrif Suite and Orange River Group represent genetically related calcalkaline plutonic and volcano-sedimentary assemblages of Palaeoproterozoic age formed during the Orange River orogeny. Together they ... -
A geochemical study of the Middle Group chromitites, Helena mine, Bushveld complex, South Africa
(University of the Free State, 2011)The study in hand reports on compositional variations in mineral and whole-rock geochemistry of the chromitite and silicate layers occurring in the Middle Group of the eastern Bushveld Complex. Special attention is paid ... -
Investigation into alternative wheat aphid control strategies for emerging farmers
(University of the Free State, 2011)In the Qwa-Qwa and Thaba N’chu regions of the Free State Province, South Africa, resource limited farmers that produce wheat are mainly situated in temporary crop environments. They are drastically affected by crop losses ... -
Aspects of the hydrogeochemistry of the Karoo sequence in the Great Fish River basin, Eastern Cape Province, with special reference to the groundwater quality
(University of the Free State, 1978-12)The aim of the study was to examine some of the major aspects responsible for the chemical quality of the groundwater in the Great Fish River Basin and its influence on the irrigation water. Approximately 18 000 ha of land ... -
A proposed method to implement a groundwater resource information project (GRIP) in rural communities, South Africa
(University of the Free State, 2005-07)English: Groundwater forms an essential part of water supply in the Limpopo Province, South Africa. However, at planning level this message seems to be skewed and misinterpreted. Although a vast number of water supply ... -
The seismo-deformation of Karoo aquifers induced by the pumping of a borehole
(University of the Free State, 2003-09)The research unequivocally showed that pump-induced seismo-deformations exist, especially in boreholes equipped with electric and diesel pumps. Central to seismo-deformations are the mechano- and the geo-acoustic effects ... -
