The Alex du Toit Memorial Lecture takes the form of a biennial lecture tour by an invited speaker. The subject of the lecture should be related to the geology or natural history of southern Africa, or on a topic that contributes to our understanding of southern African geology. Ideally, the lecture should be framed in the context of A L du Toit’s seminal text “Our Wandering Continents”. The intention of the series is to recognise world-class research in the Earth Sciences and to give the GSSA membership access to both the work and the champions through a series of lectures to be delivered at the main centres, branches and divisions of the Society and, where possible, its associated societies.
