Dr Martin Clark, chair of the local organising committee, is looking forward to welcoming delegates to the GeoCongress.

In just more than three weeks, the University of the Free State (UFS) will open its doors to delegates attending GeoCongress 2025, hosted in collaboration with the Geological Society of South Africa. From 23 to 27 June 2025, academics, industry professionals, and students will come together on the Bloemfontein Campus to share knowledge, discuss new research, and connect with peers in the geosciences.

This biennial event will feature a dynamic programme of workshops, keynote addresses, and presentations covering a broad range of topics in the field.

Message from the event organisers and UFS leadership

“It is a unique honour to be able to host the national GeoCongress, being responsible for bringing together our partners in industry and academia to share our evolving understanding of the rocks, minerals, and advances in the geosciences and associated disciplines. My view of the GeoCongress stems from my appreciation and understanding of one of South Africa’s most highly regarded geologists, Dr Hans Merensky. Dr Merensky is credited with finding platinum in the Bushveld, diamonds in Namaqualand, and phosphorus and vermiculite in Phalaborwa. However, less remember was Dr Merensky’s ability to coordinate comprehensive investigations of rocks, and his tenacity in exploring across the South African landscape. For this, I believe our theme Embracing Change through Collaboration is apt, since it's through interactions between various sectors that we are best able to handle the challenges of tomorrow,” comments Dr Martin Clark, Senior Lecturer in the UFS Department of Geology and principal investigator of the Merensky Group for Airborne Geological Image Classification (MAGIC) at the Department of Geology.

“The 2025 GeoCongress symbolises the principles of sustainable research and innovation that we advocate for in the Faculty of Natural and Agricultural Sciences and underscores our dedication to the development of interdisciplinary collaboration. Research collaboration through our Green and Complex Research Hubs is consistent with the congress theme of ‘Embracing Change Through Collaboration’. By integrating geoscience research with broader sustainability and technological advancements, we guarantee that our scientific discoveries make a significant contribution to both environmental stewardship and industry," said Prof Paul Oberholster, Dean of the Faculty of Natural and Agricultural Sciences.

Outstanding line-up of attendees

GeoCongress 2025 is set to bring together some of the most influential minds in geoscience, creating a space where leading academics, industry experts, and emerging researchers can exchange ideas and insights. Attendees will have the opportunity to engage with key figures shaping the field, including Prof Glen Nwaila, Director of the Wits Mining Institute and a leading authority in economic geology and geometallurgy at the University of the Witwatersrand; Prof John Carranza, a highly regarded researcher at the UFS; and Sifiso Siwela, Chairperson of the SAMCODES Standards Committee and past president of the Geological Society of South Africa.

Adding to the wealth of expertise, Dr Geoffrey Howarth, Senior Lecturer at the University of Cape Town and Head of the Electron Microprobe Facility, will bring his knowledge in mineral studies, while Prof Susan Webb, Associate Professor of Geophysics at the University of the Witwatersrand and acting co-director of the DSI-NRF Centre of Excellence for Integrated Mineral and Energy Resource Analysis (CIMERA), will share her insights into geophysical research. Dr Hayley Cawthra, specialist scientist at the Council for Geoscience, will contribute her expertise in coastal geology, and Prof Steve McCourt, President of the Geological Society of South Africa and Professor Emeritus at the University of KwaZulu-Natal, will bring his experience in structural geology. The line-up also includes Prof Wolfgang Maier from Cardiff University, whose research on magmatic ore deposits continues to influence the field.

To make the most of your GeoCongress 2025 experience, be sure to take full advantage of the networking opportunities – from informal meet-and-greets to engaging panel discussions. Don't miss the chance to attend hands-on workshops and exciting field excursions. These excursions offer a deeper look into the country’s rich geological history, with opportunities to visit Florisbad, Kimberley, the Beatrix operations in the Goldfields, or the Drakensberg.

Shack study holds research and social upliftment opportunities

When Prof Basie Verster, retired head of the Department of Quantity Surveying at the University of the Free State (UFS), initiated an alternative form of housing for Johannes - one of his employees - a decision was made to base research on this initiative. This research project in Grasslands, Heidedal focused on the cost and energy efficiency of green and/or sustainable shacks.

Esti Jacobs from the Department of Quantity Surveying, together with an honours student in Quantity Surveying, a master’s student in Architecture, and young professionals at Verster Berry, helped with the project.

The physical goals of the project were to create a structure that is environmentally friendly, and maintains a comfortable interior climate in winter and summer, as well as being cost-effective to erect. The structure also had to be socially acceptable to the family and the community.

“The intention was to make a positive contribution to the community and to initiate social upliftment through this project. Structures such as the ‘green shack’ may serve as an intermediate step to future housing possibilities, since these structures are relatively primitive, but have economic value and could be marketable,” she said.

Esti explains the structure of the building, which consists of gum poles and South African pine bearers, with a timber roof and internal cement block flooring. The building is clad with corrugated iron and has a corrugated iron roof finish. Additional green elements added to the structure were internal Nutec cladding, glasswool insulation in walls, internal gypsum ceiling boards with ‘Think Pink’ insulation, internal dividing wall and door, polystyrene in the floors, and tint on the windows. A small solar panel for limited electricity use (one or two lights and electricity to charge a cellphone) and a Jojo water tank for household consumption by the inhabitants were also installed.

Esti said: “Phase one of the research has been completed. This phase consisted of an investigation into the cost of an alternative form of housing structure (comparing traditional shacks with the planned structure) as well as the construction process of the physical housing structure.

“Phase two of the research, commencing in February 2015, will last for two to three years. This phase will include the installation of temperature and relative humidity logging devices inside the existing traditional shack and the new green shack. The logs will be regularly monitored by the UFS Department of Quantity Surveying and Construction Management.

These data will enable the researchers to measure the differences in comfort levels inside the two different structures. The data, together with other information such as building materials and methods, are then processed by software programs. Through the simulation of different environments, building materials, and alternate forms of energy, software models can be used to come up with conclusions regarding more energy-friendly building materials and methods. This knowledge can be used to improve comfort levels within smaller, low-cost housing units.

The UFS will be working with Prof Jeff Ramsdell of the Appalachian State University in the USA and his team on the second phase of the project.

“This research project is ongoing and will be completed only in a few years’ time,” said Esti.

The results of the research will be published in accredited journals or at international conferences.
