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 university’s Autumn Graduation Ceremony infused the Bloemfontein Campus with exhilaration last week.

Beaming with pride, graduates received 526 diplomas/certificates and 2 796 bachelor’s and honours degrees in total.

Prof Jonathan Jansen, Vice-Chancellor and Rector, lead each procession of graduates from the Red Square down the path to the Callie Human Centre while the beat of drums filled the air. “To break the cycle of poverty, get an education, get a degree,” Prof Jansen urged graduates during their respective ceremonies. He underscored the fact that, as graduates, they are ten times more likely to get a job, with the odds rising as they continue their postgraduate studies.

Dr Khotso Mohele, Chancellor of the university, advised graduates not to allow life’s obstacles to discourage them. “Take what you have learned over the last three or four years and use that knowledge to reach your goal,” he said. He also emphasised that graduates need to be able to take standpoint against issues.

Graduates’ ceremonies were made even more memorable by various local and international speakers and performers.

American student and tap-dancer, Joshua Johnson, inspired the audience with his story of hope and perseverance. As a student from Penn State University, he travels five hours by bus to New York every weekend where he dances on the subway train to earn money for his tuition fees. Joshua told graduates that, in order to achieve their goals, they have to make the best use of the 24 hours they get to live daily. “Don’t follow in the footsteps of someone else. Take the beat of life, but add your rhythm to it," his wise words resonated with the exhilarated graduates. The audience could not help but clap to the rhythmic beat of his tap-dancing performance.

Vicus Visser, dubbed Bloemfontein’s Justin Bieber was also on the list of performers. Vicus – a South African YouTube singing sensation – performed with his brother, Vincent, to the delight of the crowd.

Radio personality and Idols South Africa judge, Gareth Cliff, was also among the speakers who addressed the graduates during the week. “It’s a good time be alive, a good time to be a South African, a good time to be a qualified South African,” he said. “It’s a time in our country’s development that we require minds such as yours to propel us forward,” was part of his message. Gareth also stressed the freedom of speech in South Africa, especially the freedom of the media.

The Autumn Graduation Ceremony of 2013 was an immense success and filled the hearts of Kovsie graduates, students, staff, parents, family and friends with overwhelming pride.

The Qwaqwa Campus’ graduation ceremony will take place on 8 June 2013. Diplomas / certificates up to and including doctorates will be awarded at this ceremony.
