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.

Media: Moshoeshoe-lesing waardevol

Waardevolle lesing

DIE eerste koning Moshoeshoe-gedenklesing van die Universiteit van die Vrystaat het sommer met die intrapslag prikkelende gedagtes opgelewer en wys dat dit ’n paslike en nuttige manier is om ook die bydraes van swart leiers in Afrika te eer.

Terselfdertyd verskaf die eerste gedenklesing wat deur prof. Njabulo Ndebele, vise-kanselier van die Universiteit van Kaapstad gelewer is, diep stof tot nadenke en debat.

Die gedenklesing kom juis terwyl al hoe meer wenkbroue gelig word oor die skepping van ’n ander forum, die Native Club, waarvan wit Afrikane uitgesluit word.

Dis die geesteskind van mnr. Titus Mafolo, politieke raadgewer van pres. Thabo Mbeki, en die doel daarvan is om ’n forum te verskaf vir Afrika-intelligentsia.

In teenstelling met die ras-eksklusiewe Native Club wat ’n ongelukkige teruggryp is na rasgegronde instellings onder die apartheidsbewind, het prof. Ndebele in die gees van die inklusiewe leierskap van koning Moshoeshoe van Lesotho die gedenklesing opgedra aan al dié mense in Suid-Afrika en elders wat die moed het om hul oorwoë mening uit te druk oor belangrike sake wat die samelewing in die gestig staar.

Hy het tereg bygevoeg dié lesing kom op ’n kritieke punt in Suid-Afrika se nuwe demokrasie.
Prof. Ndebele het daarop gewys dat koning Moshoeshoe – Lesotho het onder sy leierskap mense van verskeie dele van die subkontinent gelok – kon bewys dat verskeidenheid ’n bindende eienskap kan wees.
Jy bereik die grootste eenheid tussen onderskeidende entiteite waar jy relatief vrye ruimte aan hulle gee om hul eiesoortige kenmerke na vore te bring.

Prof. Ndebele het ook opgemerk ’n toenemende aantal hoogs intelligente, sensitiewe en toegewyde Suid-Afrikaners oor die klas-, ras- en kulturele spektrum heen, bely dat hulle soos nooit tevore nie, onseker en kwesbaar voel sedert 1994.

Hierdie koerant spreek ter aansluiting hierby die wens uit dat die ANC-regeringsalliansie sal toesien dat wie ook al die leiding vorentoe in dié alliansie oorneem, ook daardie saambindende eienskappe moet besit wat koning Moshoeshoe gehad het. En wat hy gebruik het om sy land uit te bou en te verenig.
