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.

Prof. André Keet, Director of the Institute for Reconciliation and Social Justice at the university, has been appointed as member of the Oversight Committee on the Transformation of South African Universities. He is one of seven committee members that were appointed by the Ministry of Higher Education and Training to monitor progress on transformation in public universities.

The committee will advise Dr Blade Nzimande, Minister of Higher Education and Training, on policy to combat racism, sexism and other forms of unfair discrimination in public higher education. The committee will also advise on the role of universities in promoting the development of a free, fair and non-discriminatory society beyond the world of the academia.

The senior leadership of the university has welcomed the appointment of Prof. Keet and said with his extensive experience as a former Commissioner on the Commission for Gender Equality and as the Director of the university's Institute for Reconciliation and Social Justice (which was formed as one of several initiatives taken by the senior leadership in the aftermath of the Reitz incident), Prof. Keet will be a valuable member of the committee.

"Prof. Keet has the experience and expertise to guard the autonomy and academic freedom of universities, thus avoiding this committee from becoming a political intervention in the affairs of the higher education sector," said Prof. Jonathan Jansen, Vice-Chancellor and Rector of the university.

Honoured to be elected on the committee, Prof. Keet said he is ready to serve the national interest in the transformation of South African universities. "The appointment is also a compliment to the university and to its exceptional experience in the process of transformation."

Prof. Keet will serve on the committee for a period of three years. The other members of the committee are Prof. Malegapuru Makgoba, who will serve as chairperson, Dr Mvuyo Tom, Ms Nazeema Mohamed, Ms Zingiswa Losi, Mr Joe Mpisi and Prof. Shirley Walters.
