Abstract

Australian passive margins display a large variety of styles, including narrow, wide, volcanic and non-volcanic margins. Their tectonic history has been complicated by tectonic reactivation and anomalous subsidence/uplift, widespread at various times during the post-rift phase. Defining the exact location of the boundary between continental and oceanic crust (COB) is of key importance to understanding the structure and evolution of continental passive margins. Here, we review the history of Australian passive margins and the location of the COB, and we assess rift-related magmatism and anomalous post-rift subsidence based on recently acquired seismic reflection data, available industry data, and current tectonic models for margin evolution.
