Dr Jarlen Keet is excited about the various technological advancements in the field of geology that offer many benefits to researchers like herself, given that geology is an ever-evolving field. She received her PhD in Geology at this year’s April graduation ceremonies.
Dr Jarlen Keet, Lecturer in the Department of Geology at the University of the Free State (UFS), received her PhD qualification at the April graduation ceremonies of the university.

The title of her thesis is: A multi-isotope (S-Sr-Nd) investigation of the Flatreef, Northern Limb, Bushveld Complex: Petrogenetic implications and comparison with the Merensky Reef.

I hope that with my contribution, mining and exploration companies can improve their understanding of ore formation in the Bushveld Complex and globally
Flatreef the future of platinum mining in South Africa

With her thesis, she makes a significant contribution to understanding the formation and origin of the Flatreef in the northern limb and how it relates to the Merensky and Bastard units in the remainder of the Bushveld Complex – the world’s largest repository of platinum-group elements (PGEs) – which are widely used in various industries. Primary uses of PGEs include their application in LCD screens in the electronics industry, chemotherapy drugs and pacemakers in the medical field, and the production of catalytic converters that reduce harmful emissions from vehicles. 

She used isotopic data to show that the Flatreef is a correlation of the Merensky and Bastard rock units in the Bushveld Complex. Her findings also support evidence suggesting that the Main Zone was not the source of PGEs in the Flatreef, and by extension the Merensky Reef, which goes against previous beliefs.

According to Dr Keet, the Flatreef, located south of the town Mokopane, represents the future of platinum mining in South Africa.

Importance of research on the mining industry

She believes the importance of mining PGEs in South Africa is undeniable. 

“Research on our mineral resources is therefore important to our mining industry. The better we understand our PGE deposits and how they formed, the better ore models we produce, and the more we can improve on our exploration techniques and mining methods. I hope that with my contribution, mining and exploration companies can improve their understanding of ore formation in the Bushveld Complex and globally,” says Dr Keet, who was introduced to research on the Bushveld Complex during her honours project, which focused on the Merensky Reef. “I have been hooked ever since.”

Driven to excel by her inherent desire to always be her best and motivated by gratitude, Dr Keet plans to establish herself as a young scientist in her field in the next five years by supervising MSc projects and publishing more articles.

The Qwaqwa Campus welcomed its new Head in the person of Prof Prakash Naidoo. Prof Naidoo, former Deputy Vice-Chancellor: Finance (Resources and Planning) at the Vaal University of Technology (VUT), received a very warm welcome from the staff, students and the Eastern Free State community.

In response to his welcoming, Prof Naidoo thanked among others, his predecessor, Dr Elias Malete, for his leadership of the campus, as well as the Head: Operations, Teboho Manchu and the Head: Academic, Dr Elsa Crause, for their support during his first few days on campus.

“I am elated to be joining an institution that is serious about transformation. There is still a lot of work ahead to make this campus the best,” said Prof Naidoo.

“Positive vibrancy exists here and all of us must begin to think about how we can multiply the effect to make it even better.”

“This year the campus is celebrating its tenth year in existence as part of the University of the Free State and we have accomplished much in this time. However, there is still a lot to accomplish in the next 10 years. We need progressive change. Let us all look ahead, but let us never forget the past.”

“Today’s students live with greater complexities, like watching too much TV and reading less. They need more counselling and guidance. In my book, students come first. Academic business comes first.”

Prof Naidoo expressed his optimism in working with all internal and external stakeholders.

“I am a team player and we must all develop a working plan for this campus,” Prof Naidoo said.

The welcoming was attended by members of the Council and the Rectorate.
