Reeve et al. (2022) address the stratigraphic record of continental breakup by focusing on a set of stratigraphic unconformities from a proxima l sector of the NW Australian continenta l margin, inboard from the Exmouth Plateau. They suggest that such unconfor mities can potentially document a well-defined three-stage process: end of the synrift phase, formatio n of a wide continent-ocea n transitio n zone (COTZ) and generatio n of 'true' Penrose-type oceanic crust. We counterargue that continental breakup is a protracted event that can only be understood via seismic-and chronostratigraphic correlations of strata, and their composing sequences, across and along rifted margins. Tying proxima l stratigraphic unconfor mities to magnetic anomalies outboard from the study area in Reeve et al.
