Las arenas eólicas del Pleistoceno Superior en Gibraltar

Abstract

During the period represented by the sandy infills of the eastern flank caves and the Catalan Sand formation, it was likely that Gibraltar was part of the mainland, including a broad coastal plain covered with transgressive wind-blown dunes. All aeolian formations originated on marine beaches, from 6 m a.s.l. to 100 m b.s.l., before being blown inland to accumulate as topographic dunes. Cliff-front aeolian accumulations comprise echo dunes, climbing dunes and sand ramps. Aeolian deposition began immediately before the last interglacial marine highstand (MIS 6-5 transition) and continued during the subsequent fall in sea level until the end of MIS 3.
