Sub-programme leader: Dr Eugene Bergh (Eugene.Bergh@nwu.ac.za)
Strategic Aim and Mission
The aims of this subprogram are to study and advance our understanding of the composition and timing of internal and external processes determining our planet, the history and evolution of life, exploration and beneficiation of resources, the role of soils as the critical interface between geo- and biosphere as well as human interferences with natural environments and necessary mitigations.
Vision: To bring together scientists and research from various disciplines of geology, soil science and (palaeo)ecology present at NWU.
Mission: Promote research in Earth and Soil Sciences with an emphasis in multi-disciplinary research to strengthen the understanding of past and modern environmental change and the use of Earth resources.
- Environmental geology
Focuses on the integration and application of geosciences to the field of rehabilitation and the study of both natural and anthropogenic disturbances to the environment. This research field is of increasing importance due to the strong impacts of climate change, mining and other human activities.
- Petrology and mineral petrography
Vital research within geology aims to particularly focus on key geological events, such as the Vredefort Dome, Bushveld Igneous Complex and Witwatersrand Supergroup, that form part of the history of our continent and contributes towards our economy.
- Soil Science
Focuses on soil classification, digital soil mapping, soil physics and -chemistry, soil amelioration
- Environmental change studies
Focuses on the natural responses of Earth during the past geologic time. Also, modern environmental change brought on by anthropogenic influences.
- Marine and coastal sedimentology
Focuses on the study of depositional records primarily around southern Africa and the processes responsible for them.
The use of isotopes and biostratigraphy to date sediments and rocks for exploration, palaeoceanographic and palaeoenvironmental work.
- Economical geology
The exploration and petrography of mineral ores, but in addition, a more specific focus will be placed on coal petrology, structural geology and the transition towards renewable resources from 2023 onwards.
Focuses on Cenozoic palaeoecology, terrestrial and marine palaeoenvironments with expansion into Permian palaeoecology.
A transdisciplinary field investigating the geological and palaeontological context of archaeological sites with a current regional focus on southern Africa and the Near East. Our thin sectioning equipment allows for an extension into the field of microfacies analysis in 2023.

Research within the subprogram strives to enhance our understanding of Earth processes over time and in the modern context. The objectives of research in this subprogram are therefore to:
- Understand how Earth is changing in the modern context
- Understand how Earth has responded in the past to natural processes
- Understand past environments and ecologies
- Promote research into mineral ore geology
- Understand processes, relationships and geochemistry between the different Earth spheres (biosphere, lithosphere, hydrosphere)
- Promote soil science and related processes
- Environmental Soil Science
- Petrology and Economic Geology
- Sedimentary Environments and Palaeoecology
