Résumé
The present Huelva estuary is formed by bodies of salt marsh and sand bars corresponding to ancient coastal system generated during the mid-late Holocene. The upper sedimentary layers of La Cascajera sand barrier are constituted by a tempestitic sequence of northward progradational washover-fans. The geological signature of these high energy formations depends on the type and availability of source material for transport, flow dynamics, topography and preservation potential. The calibrated and modelled AMS dates in marine shells provide a storminess time range between the second half of first century BC and the entire first century AD.
