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 Centenary ends with a weekend of festivities
2005-02-04

The University of the Free State ’s (UFS) Centenary celebrations will come to an end this weekend with a packed programme.

“We celebrated this momentous milestone of the UFS since 28 January 2004 and want to end the year on a high note,” said Mr Jan Ras, Centenary Coordinator.

The weekend will start on Friday 4 February 2005 when Prof Frederick Fourie, Rector and Vice-Chancellor, will open the UFS officially. This will be followed by an historic photo of all staff and students who are on campus that day. All staff will be wearing their academic gowns and the Centenary emblem will be depicted.

The annual Kovsie Engen Rag, with We thank you South Africa as theme, will take place on Saturday 5 February 2005 . The procession will start at 08:00 from the UFS Kovsie church and will move down Nelson Mandela Drive and right into Markgraaff Street exit until it reaches St Andrew’s Street. From here it will turn right into Kings Way where it will stop at the Art Market at 10:00 . Prof Frederick Fourie will then propose a toast on the procession. Afterwards the groups and orchestras will step out and the floats will move through the center of town around Hoffman Square and then back to the UFS campus.

According to Mr Ras a reunion for the Student Representative Council (SRC) will also take place this weekend. About 100 former SRC members are expected to attend the planned activities.

The weekend will be concluded on Sunday 6 February 2005 with a special service of devotion, hosted by all the interdenominational groups on the campus. The service starts at 18:00 for 18:30 in front of the Main Building of the UFS and will be a celebration of praise, thanks and worship, followed by a message from Dr Wollie Grobler. The evening will be concluded with a mass choir and a fireworks display.

“Members of the public are welcome to attend the service of devotion and are requested to bring a candle for the purpose of the mass choir. Although chairs will be arranged in front of the Main Building , people are requested to bring extra pillows and blankets to sit on,” said Mr Ras.
