  4. Winter Warmers: Bunbury Basalt – the Solid Foundation to Bunbury

Published 29 May 2024

Learn from geologist Michael Freeman how 130 million-year-old volcanic eruptions set the scene for losing India and shaping Bunbury.

The Bunbury Basalt came from currently unknown volcanoes and flowed along two long river valleys that had carried run-off from Antarctica. The volcanic activity was related to the East Gondwana continental plate splitting when India left and it tracked north to hit Asia. The volcanic rock outcrops led to the formation of Koombana Bay as the coastline has changed through sea levels rising up to 70 metres and falling as much as 130 metres in recent geological times.

Our presenter for this session is Michael Freeman.
