Shoreface deposits can act as excellent proxies for basinal conditions, recording relative sea level fluctuations and tectonic episodes as changes in sediment type, and depositional architecture. The Gippsland Basin contains a continuous succession of amalgamated clastic shoreline deposits from the Cretaceous to present day. This basin has experienced a number of major tectonic, eustatic, climatic and oceanographic events during the Cenozoic. From the Late Cretaceous to the Miocene, stacked shoreface deposits display progradational to transgressive geometries. Despite a range of significant allocyclic events, these shoreface deposits are predominantly transgressive, and strong basinal subsidence appears to be one of the major driving forces controlling shoreline behavior.


Elizabeth Mahon is a PhD candidate at the University of Melbourne, researching the structural and stratigraphic history of the Gippsland Basin. Prior to beginning her PhD she worked for Chevron in the Australian Business Unit.

About the GSA

The Geological Society of Australia was established as a non-profit organisation in 1952 to promote, advance and support Earth sciences in Australia.

As a broadly based professional society that aims to represent all Earth Science disciplines, the GSA attracts a wide diversity of members working in a similarly broad range of industries.
