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.

Arts Festival Rally promises to be great fun
2009-05-20

The annual Amazing Rainbow Rally, presented by the Department of Paediatrics and Child Health and UFS Marketing, will take place on Friday, 17 July 2009 during the Volksblad Arts Festival on the Main Campus of the University of the Free State (UFS) in Bloemfontein.

This year all the checkpoints will be on the campus and around the Arts Festival grounds. Corporate companies in Bloemfontein and departments at the UFS may still enter teams and checkpoints.

The closing date for entering teams is 26 June 2009. A team consists of two team members who must work together to complete a route with various checkpoints. The team, who finishes first after having successfully completed all the tasks, is the winner. Last year, Dr I Babst en Dr L Solomon from the Department of Paediatrics and Child Health were the winners of the Rally.

The closing date for entering a checkpoint is 17 June 2009. Teams must complete tasks at every checkpoint before proceeding to the next checkpoint. The company sponsoring the checkpoint will also be responsible for handling the activity at the checkpoint.

The “Arts Festival” Rally promises to challenge teams physically, mentally and even artistically. Festival goers will also have the opportunity to see what teams get up to and how their favourite team is doing.

The Rally will be presented for the fifth time in 2009. The main goal of this year’s Rally is to raise funds for the Department of Paediatrics and Child Health’s “Beds of Hope Campaign”. This campaign seeks to increase the number of intensive care beds in the paediatric and neonatal wards. Currently around 250 children and babies in central South Africa cannot receive the life-saving care they need because of a lack of facilities.
