Geologist shares ground-breaking findings at Alex du Toit lecture

The Department of Geology at the University of the Free State (UFS) was recently the host of a lecture in the 2018 Alex du Toit Memorial Lecture series.

The speaker at this event was the A-rated NRF researcher, Prof Lew Ashwal from the University of the Witwatersrand. He addressed academics and geology students on ‘Wandering continents of the Indian Ocean’.

Lost continent found

In this talk he specifically shared the research he conducted on the islands of Madagascar (which he visited 30 times to conduct field work and says it is not for the faint-hearted), the Seychelles, and Mauritius. 

Two things stood out in his lecture: the way in which his findings on the three islands helped to refine details about the assembly of the Gondwana supercontinent, and the report of a ‘lost continent’ found under Mauritius. 

These discussions were linked by Prof Ashwal’s belief that the so-called lost continent he found under Mauritius is a leftover from the break-up of Gondwana,

The discovery was made when he and a team of researchers found zircon from 2000 million years ago on a 9-million-year-young island. He believes that the piece of crust (where the tested zircon probably formed), which was covered by lava during recent volcanic eruptions on the island, is a tiny piece of the ancient continent which broke off from Madagascar, when Africa, India, Australia and Antarctica split up and formed the Indian Ocean.

Media frenzy 

The fact that the team of researchers found these extremely old minerals proves that there are materials under Mauritius that originated from a continent under the island. 

Prof Ashwal is studying the break-up process of the continents in order to understand the geological history of the planet.

For his work Prof Ashwal has enjoyed coverage from publications as far apart in focus from each other as The New York Times and Cosmopolitan magazine.

They are amongst the top 15 percent of academic achievers at the university, and have been afforded the opportunity to travel abroad and meet with leading people in their fields of study.

Kovsie students Michael van Niekerk, Siobhan Canavan, Mpoi Makhetha and Cebolenkosi Sokhela, all members of the Golden Key International Honour Society, will travel to the USA and China. This trip is part of the International Scholar Laureate Program (ISLP) to learn how their career fields are practiced in another part of the world. The students are part of a select group of outstanding university students from across the world who will be given access to people, places and global perspectives in fields such as business, engineering, medicine, nursing, diplomacy and international relations.

Michael, a fourth-year MBChB student and SRC member of our Bloemfontein Campus, and Cebolenkosi, a third-year BSc Microbiology student will visit Washington, Philadelphia and New York in the USA. As part of the medicine delegation of the programme, they will visit clinics and hospitals to see how their study fields are practiced. Michael’s trip includes a visit to Johns Hopkins University in Baltimore, where he will meet representatives of the National Institute of Health, the largest source of funding for medical research in the world. He will also visit Harvard University in Massachusetts.

Mpoi, a third-year BSc Human Molecular Biology student, also forms part of the medicine delegation but will travel to China. "We will be exploring the ancient ways of healing versus the modern medical practices, exploring the medical systems of the country and meeting doctors and professors, visiting the rural areas, and of course, touring the best parts of China,” she said.

Siobhan, a third-year Media Studies and Journalism student, is part of the diplomacy and international relations delegation who will visit Beijing, Xi'an and Shanghai in China. "To me it's such an honour to be part of this programme,” she said. “It will give me the platform to not only represent who I am, but also my university and the values that the university has instilled in me. It allows me to be a part of something great that will benefit me in the end."
