文摘

Five very coarse grained nearshore-beach sequences are proposed in the Cadiz coast. These sequences are dated as Pleistocene (from 1.3 Ma to 21,970 ± 80 BP). Sequence 1 is topographically higher. Sequences 2–5 are in present intertidal zone. Sequence 5 is in a downthrown block towards the SE of Cadiz city due to neotectonics. Pleistocene sea-level variations are recorded. Main drop is at the end of Sequence 1.
