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.

Projects of the South Campus inspire excellence
2014-12-18

The University of the Free State’s (UFS’s) South Campus in Bloemfontein runs several projects to make a difference in the lives of learners and educators in the central region. These projects are based on the very essence of the UFS – to ‘inspire excellence, change lives’.

Three projects which have been very successful since the outset are the UFS Schools Partnership Project, the Family Math and Family Science Project and the Internet Broadcast Project.

The Schools Partnership Project attempts to empower teachers by improving their teaching skills in critical Gr 10 – Gr 12 subjects (Physical Science, Mathematics and Accounting).

Poorly performing schools are invited to join in the programme. A mentor, providing guidance to teachers in the planning of lessons, transferring knowledge and creating a healthy learning environment in the classroom, is assigned to each subject teacher. Management and leadership skills are also improved.

Hercules Dreyer, Programme Manager, says the success of the programme can be seen in the lessons, the results and the progress which have been made.

“In 2013, the pass rate of participating schools has grown from 71.5% to 85%. We had an increase in donors and the project went from 22 schools with 12 mentors in 2013 to 72 schools and 34 mentors in 2015.”

The UFS Family Math and Family Science Project, which is already in its sixth year of existence, are extremely popular. This intervention programme focus on bringing about a better understanding of Mathematics and Science in learners, teachers and parents.

Dr Cobus van Breda, Programme Director of the Family Math and Family Science Project, says that judging by the feedback from teachers, it is evident that the programme is growing from strength to strength and that it is making a real difference in Mathematics and Science education in the early school years.

The UFS’s Internet Broadcast Project (IBP) has thus far received four awards for their successes. In this project, lessons in Mathematics, Accounting and Physical Science are broadcasted from the UFS’s South Campus through internet presentations to schools in rural areas.

“To date, the IBP catalogue contains over 2 000 video lessons and in 2013 alone, the 68 schools accessed and used these videos 69 305 times. The project has the potential to reach more than 40 000 learners and 1 765 teachers every week,” says Sarietjie Musgrave, Project Manager.
