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.

Health Sciences expand their training platform to Trompsburg
2014-04-03

We will soon be able to accommodate more students who wish to obtain a qualification in the medical profession, after an agreement was reached between the UFS’s Faculty of Health Sciences, the Department of Higher Education and Training and the Free State Department of Health.

Some R28 million were allocated to the UFS for setting up two new Health Sciences facilities.

It is through this agreement that the Faculty of Health Sciences recently bought the Midway Hotel in Trompsburg, in order to expand their training opportunities platform for students in the faculty. Two other facilities are currently being negotiated for Kimberley and the Eastern Free State.

Prof Gert van Zyl, Dean of the faculty, says their training platform at the Universitas Academic Hospital (including Universitas Hospital, the National District Hospital, Pelonomi Hospital, the Free State Psychiatric and 3 Military Hospital) is saturated.

“We couldn’t accommodate additional students without compromising the quality of practical training. We are forced to expand the training platform to other good primary health facilities which will be accredited by that the Health Professions Council – in this case the new Trompsburg.”

Prof Van Zyl says the necessary infrastructure must be put in place before student numbers can be increased. Some of the plans include:

  • Furnished accommodation in Trompsburg for about 50 students from the School of Medicine, School of Allied Health Professions and the School of Nursing.
  • Administrative and academic support points, including office space for administrative and other essential learning areas.
  • Equipment and facilities for e-learning.
