Estratigrafía del Eoceno Prebético: edad, evolución y organización en ciclos
Thirteen sections have been studied along the Betic Cordillera (Alicante, Murcia, Granada and Jaen sectors) in the Prebetic Eocene. The sedimentary realms were mostly shallow marine. Three informal stratigraphic formations were proposed and dated with planktic foraminifera, calcareous nannoplankton and Larger Benthic Foraminifera: (1) lower marly ...Tent-Manclus, Jose Enrique +5 more
