PESA SA FieldTrip
From a carbonate ramp to siliciclastic fluvio-deltaics in a tectonically active Delamerian Cambrian rift. Seismic-scale depositional systems in outcrop

Saturday 16th and Sunday 17th November 2024

An opportunity to investigate the Cambrian evolution of South Australia through spectacular seismic scale coastal exposures in the Fleurieu peninsula.

The field trip will be led by Rhodri Johns and Elinor Alexander. The full excursion will be two days but participants will have the option of participating in either or both days. Participants intending
Participating in both days is encouraged to overnight at Break Free Wirrina Cove for R & R.

The first day will be spent examining the carbonate ramp deposits of the Sellick Hill Formation and the clastic turbidites of the Carrickalinga Head Formation at Myponga and Carrickalinga. Here signs of the early evolution of the Delamerian rift will be viewed. The second day will be spent viewing the spectacular outcrops of the Fishery Beach section on the south coast near Cape Jervis. Here a magnificently exposed prograding clastic sequence, including Carrickalinga Head turbidites and the shallow marine deltaics of the Backstairs Passage Formation.
