The Department of Geology at the UFS is co-hosting this year’s GeoCongress 2025 with the Geological Society of South Africa. Pictured is Dr Martin Clark, Senior Lecturer in the Department of Geology and convener of the congress.

The Department of Geology in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) and the Geological Society of South Africa will co-host GeoCongress 2025, set to take place from 23 to 27 June 2025 on the UFS Bloemfontein Campus. This prestigious biennial academic event, themed: Embracing change through collaboration, will bring together leading academics, students, and industry experts from across South Africa to explore the latest advancements in geosciences.

The congress reflects the university's commitment to academic excellence, quality, and impact – core tenets of its UFS Vision 130. As a research-led, student-centred, and regionally engaged university, the UFS continues to transform itself to stay relevant within the dynamic and ever-changing international higher education sphere.

Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation, says “The university is proud to co-host this major gathering of established and emerging earth scientists from a variety of disciplines, who will present relevant, timely research topics to a wider audience. The theme underscores the centrality of geosciences to our aspirations as a university for the country and continent, directing us towards a collective sustainable future. We are excited by the ideas to be featured at this conference. More importantly, we are inspired by the prospect of further promoting real interaction and innovation between academia, industry, and society for impactful change.”

A platform for scientific excellence

It is fitting for the UFS to co-host this event, as geologists in the Department of Geology as well as in the province have made significant contributions across multiple fields, including economic geology, palaeontology, and geomorphology.

In the Department of Geology, for instance, researchers are exploring a wide range of topics, including magmatic processes in the platinum-group-bearing Bushveld Igneous Complex, AI-driven prospectivity modelling of global deposits, meteorite impact-related processes in the Vredefort impact structure, and geological and structural studies in the Namaqualand region.

In the Free State, known for its rich mineral resources, including gold, diamonds, and coal, geologists have played a big role in exploring and developing these resources, particularly in the Free State Goldfields, one of South Africa’s leading gold-producing areas. The province also boasts significant coal deposits, important for power generation. In palaeontology, geologists have helped uncover valuable fossil sites, including the Florisbad hominid site, offering insights into the history of life on earth. Additionally, their research in geomorphology, especially around the Florisbad area, has shed light on unique landscapes and depositional environments, including lunette dunes.

In agriculture, geologists have worked closely with farmers to ensure sustainable land use, providing important information on soil composition and erosion prevention. They have also played a key role in the study of groundwater resources, helping to identify and assess borehole sites for irrigation and domestic water supply, which is key to farming in the region. The Institute for Groundwater Studies (IGS) at the UFS is the only institute in South Africa dedicated to geohydrology. Founded in 1974 by Prof FDI Hodgson, the IGS is the oldest institute at the university and has produced more than 1 000 postgraduate students. The institute conducts research on a wide variety of water-related topics. Of special interest is its contribution to the mining and industrial sectors in terms of water management, minimisation of pollution, as well as understanding the nature and behaviour of South Africa's aquifers. The IGS provides a complete service to these industries through field investigations, the development of specialised field equipment, an accredited laboratory, and computer models for aquifer management.

Building on these contributions in the field, GeoCongress 2025 marks an important event on South Africa’s geoscience calendar, showcasing the latest scientific advancements, innovative research, and practical applications shaping the industry. With engaging academic sessions, dynamic workshops, and practical field excursions, the conference offers attendees the opportunity to participate in meaningful discussions, attend insightful presentations, and take part in excursions that bring theory to life.

Opportunities for networking and growth

GeoCongress 2025 is more than just an academic gathering – it is an opportunity for professional growth and networking. Participants will meet peers, mentors, and industry leaders, establishing connections that can lead to new research projects and collaborations.

There is plenty to look forward to at this year's conference. Here are the key dates and event highlights for GeoCongress 2025. 

• Call for abstracts: Closes on 31 March 2025
• Early bird registration: Closes on 31 March 2025
• Final registration deadline: Closes on 22 June 2025

Event highlights:

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

 

Prof Marian Tredoux
17 September 2013

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
