Occurring along many of the world’s coastlines, eolianites are geographically extensive, wind-blown accumulations of skeletal carbonate sands derived from the physical breakdown of marine invertebrates from adjacent continental shelves. Eolianite successions have been of interest as archives of long-term environmental change and their potential for reconstructing Quaternary relative sea-level histories. Amino acid racemization (AAR) has been applied to the dating of eolianite successions (“whole-rock” dating) and has involved assessments of relative age, stratigraphical correlation, and, in more ideal situations, the derivation of numerical ages for eolianite units. Fossil molluscs from interstratified shelly facies have also been dated using AAR to constrain the timing of eolianite deposition.
