  Angath, Ellisha (University of Pretoria, 2021)

  The use of Berea Red sands can be seen extensively among civil infrastructure particularly along the eastern coast of South Africa. These cohesive soils vary in colour, composition, and strength. Despite the understanding ...
• Sedimentology, palaeoenvironment and structural interpretation of the Cretaceous SW Anambra Basin, Nigeria 

  Omietimi, Erepamo Job (University of Pretoria, 2022-08)

  The Inland Anambra Basin of Nigeria, formed on the western segment of the Lower Benue Trough, represents the sag phase of the Trough. Its basin infill comprises shallow to marginal marine and freshwater sedimentary clastic ...
• The potential clogging and filter performance of selected geotextiles with different soil types under unidirectional flow conditions in sub-soil drainage applications 

  Mukwevho, Fhulufhelo Vincent (University of Pretoria, 2022)

  Non-woven and woven geotextiles have long been used as a cost effective solution in different applications such as separation, reinforcement, protection, filtration and drainage. One of the most common use of geotextiles ...
• Geochemistry and spatial variation in dolerites of the Drakensberg Group, Karoo Supergroup, South Africa 

  Kotze, Arnoldus Daniel (University of Pretoria, 2022-03-08)

  The Karoo Large Igneous Province (KLIP) in South Africa comprises a spatially limited basalt suite (Drakensberg Group) and a spatially extensive dolerite suite. This study aims to establish a tectonic regime that could ...
• Comparison of the engineering geological properties of near surface and deep sedimentary rocks of the Karoo Supergroup, South Africa 

  Human, Hendrik Gert (University of Pretoria, 2021)

  The sedimentary rocks of the Karoo Supergroup cover approximately 75% of the surface area of South Africa. Major projects have been constructed on and in these rocks with a number of tunnelling projects such as the Lesotho ...
• Geotechnical and risk analyses for the positioning of shafts at the Wesizwe Platinum project 

  Clark-Mostert, Vennessa (University of Pretoria, 2011)

  The Wesizwe main and ventilation shaft positions are sited within an almost square block formed by four faults. The shaft positions were not sited within the centre of gravity of the Wesizwe lease area. This is due to ...
• Problems in parameter estimation in probabilistic seismic hazard analysis and some solutions 

  Vermeulen, Petrus Johannes (University of Pretoria, 2020)

  Probabilistic Seismic Hazard Analysis (PSHA) is not a new study field — indeed, it dates from the late 1960s. However, the original and introductory study paid scant attention to a crucial aspect, namely the estimation of ...
• Mechanical and hydraulic properties of residual dolomite and wad found in the Malmani Subgroup in South Africa 

  Swart, Duan (University of Pretoria, 2019)

  Dolomitic land is known for subsidence and sinkhole formation, making development such as housing unsafe, especially when wad is found. Wad and residual dolomite are usually found at the bedrock-soil interface and in ...
• Engineering geological mapping for urban development in low relief semi-arid regions (Outapi northern Namibia)

• Physico-chemical properties of South African shales and siltstones in the context of geological CO2 storage 

  Nxokwana, Ngqondi Songezo (University of Pretoria, 2020)

  Shale is normally impermeable and has a low porosity; it was therefore not considered by the project on geological storage of CO2 in South Africa (the “Atlas” project) as a potential storage reservoir. However, research ...
• Use of tritium and stable water isotopes to assess contaminant transport at a burial site in Middelburg, Mpumalanga 

  Mahlangu, Sarah Ndazi (University of Pretoria, 2020)
