Dramatic new insights into the origins of the Tamar Valley and the Northern Midlands are emerging from innovative 3D geological modelling that reconstructs the regions evolution over the past 40 million years. This compelling story reveals how powerful and interconnected geological forces have shaped the landscapes we know today, from broad river valleys to distinctive landforms. The research challenges long-held assumptions and culminates in a surprising new explanation for the formation of one of Tasmania’s most iconic natural features – the Cataract Gorge. Join us as we explore how cutting-edge science is transforming our understanding of northern Tasmania’s geological past.

Speakers: Robert (Bob), has a 50 year career as a geologist and consultant specialising in mineral exploration throughout Australia and overseas. Over the past four years his expertise in computer modelling of ore deposits has been applied to the Tamar Valley.

Tom is currently Senior Learning Designer at RMIT. A 30-year career infusing learning practice with technology across all public and private education sectors. He brings his digital media and presentation skills to Bob’s project.
