  The Palaeoproterozoic Hekpoort Formation of the Pretoria Group is a lava-dominated unit that has a basin-wide extent throughout the Transvaal sub-basin of South Africa. Additional correlative units may be present in the ...
• Surface water-groundwater interaction using tritium and stable water isotopes : a case study of Middelburg, South Africa 

  Mahlangu, Sarah; Lorentz, Simon; Diamond, Roger E.; Dippenaar, Matthys Alois (Elsevier, 2020-11)

  With an increasing population, development of the country and a changing climate, demand for fresh water has increased and is coupled with negatively impacted water resources. One impacted component of the water resource ...
• Hydrochemical evolution of high uranium, fluoride and nitrate groundwaters of Namakwaland, South Africa 

  Makubalo, Sisanda S.; Diamond, Roger E. (Elsevier, 2020-12)

  Water quality globally suffers from overuse and pollution, but desert areas with high evaporation rates and groundwater as the only water source have additional challenges. Namakwaland in the Northern Cape is an arid region ...

• Properties of impact-related pseudotachylite and associated shocked zircon and monazite in the upper levels of a large impact basin : a case study from the Vredefort impact structure 

  Kovaleva, Elizaveta; Dixon, Roger D. (MDPI, 2020-11-25)

  The Vredefort impact structure in South Africa is deeply eroded to its lowermost levels. However, granophyre (impact melt) dykes in such structures preserve clasts of supracrustal rocks, transported down from the uppermost ...
• An ERA-Interim HAILCAST hail climatology for southern Africa 

  Dyson, Liesl L.; Pienaar, Nita; Smit, Ansie; Kijko, Andrzej (Wiley, 2021-01)

  Understanding the character of hail is an important part of mitigating its impact on life and property. Climatologies of hail over South Africa are rare and based on observed data with a coarse spatial and temporal resolution. ...
• Investigation on the possible control of grain size on development of ‘mud cracks’: a preliminary experimental study of recent Gangetic alluvial samples, West Bengal, India 

  Banerjee, Soumyadip; Kundu, Abhik; Eriksson, Patrick George; Sinha, Subhajit (Springer, 2021-01)

  The so-called mud cracks, possibly the most common deformation feature in sediment, are evident in almost all dried-up exposed sediment surfaces. Several experimental attempts have so far been made to explain the evolution ...
• 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 ...
• Hydrogeological characterisation of regional faults and dolerite dykes in the Precambrian Basement and Karoo Supergroup (Tete Province, Mozambique) 

  Minnaar, R.C. (Ray); Dippenaar, Matthys Alois (Geological Society of South Africa, 2019-09)

  Faults and dolerite dykes within Basement- and Karoo-aquifers in northern Mozambique may increase groundwater occurrence but may also be barriers to groundwater flow. Should observation boreholes drilled into regional and ...
• Landscape responses to intraplate deformation in the Kalahari constrained by sediment provenance and chronology in the Okavango Basin

• Isotope geochemistry 

  Diamond, Roger E. (Academy of Science South Africa, 2019)

  Isotopes are atoms that belong to the same element, but have different numbers of neutrons. For example, hydrogen can have 0 neutrons (protium) or 1 neutron (deuterium) or 2 neutrons (tritium). The mass changes because ...
• 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 ...
