%X The stratigraphic relationships, genesis and chronology, including radiocarbon dating, of the Quaternary sandydeposits forming the El Asperillo cliffs (Huelva) were studied with special emphasis on the influence of neotectonicactivity, sea-level changes and climate upon the evolution of the coastal zone. The E-W trending normal fault ofTorre del Loro separates two tectonic blocks. The oldest deposits occur in the upthrown block. They are Early toMiddle Pleistocene fluviatile deposits, probably Late Pleistocene shallow-marine deposits along an E-W trendingshoreline, and Late Pleistocene and Holocene aeolian sands deposited under prevailing southerly winds. ThreePleistocene and Holocene aeolian units accumulated in the downthrown block. Of these, Unit 1, is separated fromthe overlying Unit 2 by a supersurface that represents the end of the Last Interglacial. Accumulation of Unit 2 tookplace during the Last Glacial under more arid conditions than Unit 1. The supersurface separating Units 2 and3 was formed between the Last Glacial maximum at 18 000 14C yr BP and ca. 14 000 14C yr BP, the latter agecorresponding to an acceleration of the rise of sea level. Unit 3 records wet conditions. The supersurface separatingUnits 3 and 4 fossilised the fault and the two fault blocks. Units 4 (deposited before the 4th millennium BC), 5 (>2700 14C yr BP to 16th century) and 6 (16th century to present) record relatively arid conditions. Prevailing winddirections changed with time fromW (Units 2–4) to WSW (Unit 5) and SW (Unit 6).
