Shoreline Evolution, Aeolian Deflation and Anhydrite Distribution of the Holocene, Abu Dhabi


 Easier access to most parts of the Abu Dhabi coastline, combined with satellite imagery, has enabled a more detailed examination of the Holocene strata than was possible twenty or thirty years ago. Whilst the basic principles of coastal progradations documented in those early days are still valid, they portrayed an oversimplified picture of the Holocene coastal geomorphology and sabkha sedimentology. New data re-emphasises the importance of antecedant topography in imposing depositional complexity on the Holocene System. Former Holocene shorelines can now be mapped with greater clarity and reveal its highly embayed nature. The Holocene transgressive limits are locally redefined. Some palaeo-highs, that formed earlier Holocene peninsulas, have been completely removed by deflation. Two phases of sabkha anhydrite are recognised and their distributions are largely predictable by remote sensing.
