| Abstract: | This paper analyzes the lithostratigraphic features and the ostracode associations of the Tortonian deposits located in the western and central sectors of the Guadalquivir basin (S Spain). Eight facies associations are defined (FA-1 to FA-8), being deposited in fluvial to upper bathyal paleoenvironments. The ostracofaune confirms the Tortonian age of these deposits, where three ostracode associations are defined: (a) infralittoral (i.e. Urocythereis favosa, Cytheretta orthezensis, Callistocythere spp.); (b) circalittoral (i.e. Costa batei, Celtia quadridentata, Echinocythereis scabra, Pterygocythereis ceratoptera/jonesii); and (c) outer platform/talus (Henryhowella asperima; Cytherella spp.; Krithe spp.). A comparison with the Tortonian associations of southwestern France and Portugal permits to define a common ostracod zonation for southwestern Europe for this period. |
