Upcoming Lecture

The Field Geology Club of South Australia presents:
Stone, Sand, and Silence: a decade among the tombs of Luxor
Brenan Dew
South Australian Museum

Thursday 6th August 2026 at 7.00 pm
Mawson Lecture Theatre, 
Department of Earth Sciences, Adelaide University

Abstract: For nearly a decade, Brenan Dew worked among the limestone hills of the Theban Necropolis on Luxor’s West Bank, excavating and recording the tomb of Amenmose (TT149) with the Macquarie Theban Tombs Project. This talk reflects on life and discovery in the Theban Necropolis, where geology, geography, history, and human experience converge. In this talk, Brenan shares a personal account of working in one of the world’s most extraordinary landscapes, where every layer of earth holds echoes of the past.  

Bio: Brenan Dew is a museum professional and science communicator with extensive experience across cultural institutions including the South Australian Museum, the Australian Space Discovery Centre, and Powerhouse Museum. His work spans visitor experience, public programs, and strategic engagement—bringing science, culture, and community together through accessible storytelling. With undergraduate degrees both in History and Science (majoring in Egyptology and Astrophysics), he remains deeply passionate about astronomy, dark-sky advocacy, and fostering public curiosity about our place in the universe.
 
University policy is to close doors at 7.00 pm, so arrive punctually! The door may be monitored for latecomers until the main lecture starts (around 7.10 to 7.15 pm).

BOLLA BOLLANA BOULDER BEDS by Peter Briggs

    Glaciogenic deposits are common, often seen as unconsolidated moraines, tilled up sediments and deep clay deposits, but when Walter Howchin in 1907 saw solid rocks in Sturt Gorge he realised these were ancient glacial deposits and so began the study of Glaciogenic Geology.  He brought a worldwide conference to Adelaide to further this study and soon similar ancient deposits were found around the world.  Douglas Mawson then found extensive Diamictite deposits in the Flinders Ranges, again of glaciogenic origin.  In the Gammon Ranges-Arkaroola region, we have some of the largest preserve glaciogenic deposits in the world, formed in the Cryogenian when the Earth was in near ‘Snowball Earth’ conditions for 57 Ma.  The Bollana Boulder beds are the equivalent of the Sturt Tillite and part of the Sturtian Period, a name given to represent this period worldwide.  On our doorsteps we have a world class example of this freezing time in Earths history, something we will see on our soon Arkaroola Field trip.
