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.
