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 short course on dairy
2010-05-02

The University of the Free State (UFS) will present a one-day short course titled “Adding value to milk and milk products” in the Board Room in the Agriculture Building on the Main Campus in Bloemfontein on Wednesday, 19 May 2010, from 08:15 to 17:00. The cost per person is R950,00 and it includes refreshments, lunch, practical experience and course material. The course will be presented by Prof. Celia Hugo and Dr Maryna de Wit of the UFS.

The after the course the attendants will be able to produce cheese, cottage cheese, feta cheese, maas (Amazi) and yoghurt. In South Africa milk is produced on a large scale.  With the basic knowledge anybody is able to add value to this product by further processing of the milk.

For registration contact Anita at 0836698435 or vwsdairy@ufs.ac.za. Please note that registration closes on 7 May 2010. For more information on the course contact Celia at 0514012692 or hugocj@ufs.ac.za or Maryna at 0514013261 or dewitm@ufs.ac.za.
