Caracterización sedimentaria de facies tempestíticas en barreras arenosas del estuario de Huelva (SO España)

espanolEste trabajo caracteriza las facies tempestiticas que se localizan en las barreras arenosas internas del estuario de Huelva y que conformaban la bocana de la antigua Palus Erebea romana. Su edad calibrada por radiocarbono esta comprendida entre finales del siglo I a.C. y todo el siglo II d.C. EnglishThis work characterizes the sedimentary facies of storms that are recorded in the upper reaches of the internal sand barriers at the mouth of the Roman paleo-estuary of Huelva (Palus Erebea). This storm facies reveals a very effective growth mechanism for the backshore area by means of its vertical aggradation and northward progradation during high-energy wave episodes. The calibrated and modelled radiocarbon dates in marine shells of Glycymeris provide a time range between the late 1st BC and the entire 2nd AD centuries.
