RT Journal Article T1 Cambios paleoambientales en la desembocadura del río Guadalquivir durante el Holoceno reciente A1 Ruiz Muñoz, Francisco A1 Rodríguez Ramírez, Antonio A1 Cáceres Puro, Luis Miguel A1 Rodríguez Vidal, Joaquín A1 Yáñez Camacho, Celia A1 Clemente Salas, Luis A1 González-Regalado Montero, María Luz A1 Abad de los Santos, Manuel A1 Andrés, José Ramón de AB Late Holocene palaeoenvironmental changes (~ 2000 BP) in the Donana National Park (Guadalquivir estuary, SW Spain) were studied using geomorphological techniques, lithostratigraphic analysis and ostracode faunas. Two cores were drilled in the Las Nuevas estuarine ridge, showing an environmental evolution with five phases: 1) brackish lagoon (the Roman Lacus Ligustinus); 2) energetic event (storm?, tsunami?); 3) brackish lagoon with reduction of the ostracode density; 4) transitional, with the first apparition of fresh-water species; and 5) temporary pond, located between cheniers and levees PB Sociedad Geológica de España YR 2001 FD 2001 LK http://hdl.handle.net/10272/9408 UL http://hdl.handle.net/10272/9408 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 14 jul 2026
