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.

UFS presents unique rally
2006-05-11

On Friday 9 June 2006 the University of the Free State (UFS) will present the second Amazing Race Rally in Bloemfontein. 

The rally is presented in aid of children and babies with serious diseases in the Department of Pediatrics and Child Health in the UFS Faculty of Health Sciences.  These children are in need of intensive care, and suffer from cancer, heart disease, neurological diseases and conditions, endocrinological diseases or gastro-enterological conditions.

By raising the necessary funds, equipment can be acquired to meet the unique healthcare needs of these children and babies and it will also enable the UFS to maintain the high standards of education, training and research in this field.

Last year about 12 corporate teams from among others Vodacom, Medi-Clinic, Eskom, Mimosa Mall and Nedbank and four teams from the UFS competed in the rally.  The Medi-Clinic team was the winner.

This year the teams will again follow a specific route with various check points by car.  Here they will have to complete activities or solve clues before receiving their clue to the next checkpoint.  The teams will be travelling with cars branded with the logo of the company they represent.

Companies and institutions in Bloemfontein can enter in the rally by means of sponsoring a check point, entering a team of two persons or sponsoring some aspects of the day. 

The rally will give participants an opportunity to test their knowledge of the city, as well as their time management skills, communication skills, team work and even their relationships! 

The programme will start at 12:00 on the UFS Main Campus and the first team to complete this task is the winner of Bloemfontein’s second Amazing Rainbow Rally.

Extensive publicity of the event on OFM in the weeks running up to the day will ensure that participants are easily recognised and will create a measure of excitement.

Enquiries about the rally can be directed to Ms Adéle van Aswegen at (051) 401-3535 or Ms Ilse Olivier at (051) 401-2415.
