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.

Student one of ten Google Young Minds
2012-04-23

 

Sibusiso Tshabalala is making strides as an international young leader.
23 April 2012

Third-year B.Com Law student, Sibusiso Tshabalala from our university, is one of ten of Google’s Young Minds for 2012. He made it to the top thirty from a pool of 1 700 applicants at the beginning of April 2012.

“The standard of other competitors and the panel of judges were extremely high. I was excited to receive the news that I had made it,” he says.

Annually, Google searches for ten students internationally who demonstrate strong leadership capabilities. This once-in-a-lifetime opportunity is given to students who also have an entrepreneurial drive and a commitment to social activism. Sibusiso was selected for his involvement in renovating libraries and training budding public speakers. His projects also involve encouraging literacy and critical thinking in poor areas in the Free State by establishing reading clubs.

Sibusiso will be attending the Google Zeitgeist in London from 20 to 22 May 2012.

At the conference, he will have the opportunity to meet some of the world’s greatest minds. Over 400 influential business leaders and visionaries from around the world will be hosted. Speakers include Prof. Stephen Hawking, former Lucasian Professor of Mathematics: University of Cambridge; Sir Richard Branson, Virgin Group; Eric Schmidt, Chairman: Google; Larry Page, CEO: Google; Angela Ahrendts, CEO: Burberry, and international musician will.i.am.

The ten winners will also take part in a series of ‘master classes’ with the aim of mentoring them to help further their future projects.

His achievements include the 2010 winner of the National SAGE Competition (Students for the Advancement of Global Entrepreneurship). He represented South Africa in Brazil that same year and was also National Winner of the Best Speaker Award at the 2011 South African National Universities Debating Championships. He was ranked as one of the top ten debaters in Africa at the Pan African Universities Debating Championships held in Bulawayo, Zimbabwe in 2011. Sibusiso recently chaired the committee that organised the first university based CANSA Relay for Life Event in South Africa. This took place at the UFS in February 2012.
