PS Identification of a Neoproterozoic Shelfal Suprasalt Carapace and Correlation to a Tapered Composite Halokinetic Sequence at Patawarta Diapir, Central Flinders Ranges, South Australia*

Stratigraphic and facies analysis of the Neoproterozoic Wonoka Formation and Patsy Hill Member of the Bonney Sandstone that surround Patawarta allochthonous salt sheet permit identification of an isolated suprasalt carapace section of the Wonoka Fm that is condensed and lithologically distinct from the correlative minibasin section. The two sections are spatially separated by a 3.8 km wide zone of outcropping Callana Group in the Patawarta diapir.
