Descrição
Resumo:(Morphosedimentary evidence of rapid sea-level drop in the Mediterranean coasts of Spain during MIS5e): Polygonal sandcracks developed on top of upper foreshore facies, together with facies superposition, are analysed to reconstruct rapid relative sea-level changes occurred during MIS 5e in the Mediterranean coastal settings from Spain. Geomorphological arrangement and sedimentologic analyses carried out in two sedimentary sequences from Cope Basin (Murcia, SE Iberian Peninsula) and Es Copinyar (SE Formenetera Island, Baleares) allow reconstructing sudden sea-level drops occurred during the first and second highstands of MIS 5e. The driven causes of these metric sea-level changes are not well understood yet.
