Allí migraban distintas formas de fondo movidas por comentes de deriva, de dirección E-W y sentidos cambiantes, generadas por las tormentas y vientos dominantes en la región. [ABSTRACT] The shallow-marine Pliocene succesion of Rio Alías consists of deposits laid down by prograding shallow shelf-talus and tan delta systems. The lower calcarenite member displays largescale sets of cross-bedding that are sudied in detail. Lack of definite tide-generated features, together with repeated intense burrowing of some of the foreset laminae, lead to invoke wind-driven currents, induced by storms blowing from E and W, torced through a narrow, shallow pass between two emergent islands, where the flow accelerated.spajournal articlehttp://www.raco.cat/index.php/ActaGeologicaopen access551.351.3(460)Calcarenitas marinas somerasSand WavesBajos fondosMio-PliocenoAlmeríaShallow marine calcarenitesSand wavesCarbonate shoalsMio-PlioceneGeología estratigráfica2506.19 Estratigrafía
