Description :
Six stages are recognized in the deposition of late Quaternary sediments in this area: (i) Pre-Last Interglacial, involving accumulation of separate composite units consisting of estuarine clays and transgressive dune complexes| (ii) Last Interglacial stage during which Inner Barriers were formed| (iii) Last Glacial reworking of barrier and dune sands by westerly winds| (iv) Postglacial Marine Transgression during which the Outer Barriers were initiated| (v) Mid-Holocene stage following cessation of sea-level rise ca. 6000-6500 yr B.P. on this coast, and involving progradation of Outer Barriers in some embayments| and (vi) Late Holocene episodic eolian reworking of dune complexes and Outer Barriers. The relatively high wave and wind energy as well as the tectonic setting of the central N.S.W. coast results in somewhat different geomorphic histories from barrier-island coasts in North America and Europe.
