The deposition of both pumice and shell is common on beaches during calm and storm wave conditions. This paper describes an investigation of pumice and shell ridges at two sites in Australia, one at Dark Point in NSW, and one in the Younghusband Peninsula in SE South Australia. The formation of lines of shelly and pumice rich deposits on, and above the backshore is described and their eventual exhumation by aeolian deflation within deflation plains and basins on coastal barriers is examined. A new ridge type is detailed whereby deflation ridges are formed by the aeolian erosion and deflation of shell or pumice concentrations and lag deposits.
