Wadjemup (Rottnest) Field Trip – Corals, calcareous aeolianites & Quokkas – by bike

Sunday, 2 April, 2023 @ 8:40 am - 4:30 pm (Australia/Perth time)

$80.00 – $160.00

Guest Speaker(s): Chris Elders

Chris Elders is Professor of Petroleum Geology at Curtin University.  Having spent time at Oxford, in Shell and at Royal Holloway (University of London), he has enjoyed spending the last 9 years helping to unravel the complex evolution of Australia’s continental margins.

Wadjemup (Rottnest) Field Trip – Corals, calcareous aeolianites & Quokkas – by bike

Wadjemup (Rottnest Island) is dominated by the Tamala Limestone, an extensive unit of Pleistocene carbonates that outcrops along large parts of the West Australian margin between Shark Bay and Esperance. It contains one of the world’s most significant deposits of carbonate aeolianites (wind-blown carbonates, deposited in dunes) which can be clearly seen in many of the outcrops. However, Pleistocene to Recent sea-level fluctuations have left behind a variety of other deposits and features – in-situ corals, shallow marine sediments, elevated platforms and notches, salt lakes, dunes and modern coral reefs.

A c. 17 km cycling tour of the island, taking in sights at Salmon Point, Fairbridge Bluff, the Lighthouse, Mt Herschell Quarry, and Geordie Bay will enable us to examine these different features. We will follow a circular route, with a scenic stop to eat our packed lunches (please bring your own) and return back to the settlement in time for a beer in the pub before the ferry returns to Perth.

Please note that for insurance reasons this trip is only open to members. If you are not currently a member you will need to sign up before booking.
