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.

DF Malan – the politician, the man and Lindie Koorts’ award behind it

Sometimes fact is stranger than fiction. In this case, it is not only true, but fact is stirring up more of a buzz than make-belief does.

The first biography of an apartheid Prime Minister written since 1994, won an award at the 2014 Woordfees. ‘DF Malan and the Rise of Afrikaner Nationalism’ is the title of the book causing this national whirlwind. The author: Lindie Koorts – a postdoctoral fellow at the UFS’s Centre for Africa Studies.

She admits she was among the most surprised when she won the category for Debut Writers. “This is, as far as I know, the first time this prize goes to a non-fiction writer,” Koorts said.

What started as curiosity around DF Malan, four years later culminated in an objective biography devoid of justification or exoneration. “Throughout the process of writing, I offer the facts, but I do not clamber in with moralistic judgements,” Koorts said.

In addition to Malan the politician, Koorts discovered Malan the human being as well during her research. When she stumbled on his hand-written love letters to Maria Louw, which he wrote when he was in his 60s, a totally different man emerged. “I felt like a teenager while reading those letters!” Koorts laughed.

In the chapter entitled Coalition and Fusion, this dynamic historian unearthed a fact that had the power to change the course of history. Up until this point, the belief was held that one party deceived another. However, Koorts’ research proves that the entire issue rested on a letter that did not arrive on time. A case of tardy train schedules and a mere misunderstanding.

“To be able to unravel these things makes one feel that you have succeeded in something,” she said.

Not only did she succeed in writing an award-winning biography, she surely will be making history as she goes.
