Every two years, the Fellows Committee of the Geological Society of South Africa selects earth scientists with an international reputation in research achievement to address the branches and divisions of the GSSA on a lecture tour, normally scheduled in the third and fourth quarter of the year.  Traditionally, the lectureship alternates between Southern African and more international speakers.

 

The 2018 du Toit lecturer is Professor Lewis (Lew) Ashwal of Wits University.  The title of his lecture is “Wandering Continents of the Indian Ocean”.  Many of you will be familiar with Professor Ashwal’s research over the years

 

This year we are honoured to be able to host the Memorial Lecture as part of the Summer Symposium
