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.

The atmosphere on our campuses is electric with the upcoming visit and Graduation Ceremony of Ms Oprah Winfrey in Bloemfontein.

Ms Winfrey will receive an Honorary Doctorate in Education from our university on Friday, 24 June 2011.

Every single ticket for the event was snapped up within hours of becoming available this morning (Wednesday, 15 June 2011). Staff and students queued in front of the Information Centre on our university’s Bloemfontein Campus to get their free tickets, while the general public did the same at Computicket outlets throughout the country.

The university would like to thank everyone for their positive attitude and eagerness to be part of this special day. A special thank you to all our staff and students who have volunteered their services and are helping to plan and manage the event.

The university requests everyone who has managed to secure a ticket to ensure that they arrive early on the Bloemfontein Campus that day.

On Friday, 24 June 2011, the doors of the Callie Human Centre will open for both special guests and the public in general at 13:00. The doors will close strictly at 14:00 and no one will be allowed to enter or leave the building for reasons of safety and security.

Entertainment before and after the Graduation Ceremony will be provided by acclaimed musicians such as the internationally lauded, award-winning singer Sibongile Khumalo, the Botshabelo String Orchestra, the Bloemfontein Children’s Choir and the choir of the Bartimea School for the Deaf and Blind.

After the Graduation Ceremony, Ms Winfrey will formally address the 4 500 guests, after which she will conduct a Question-and-Answer Session with students from the large audience.
