Paleoecología de los niveles lumaquélicos con Heterostegina en el Tortoniense del sector central de la Cuenca del Guadalquivir (SO España)
The Iumaquellic levels with Heterostegina in a detritic-bioclastic succession (Km 98 section) located in the central sector of the Guadalquivir Basin has been studied. The sedimentological and micropaleontological analysis (larger foraminifera, benthic and planktic microforaminifera, and ostracoda)...

| Sumario: | The Iumaquellic levels with Heterostegina in a detritic-bioclastic succession (Km 98 section) located in the central sector of the Guadalquivir Basin has been studied. The sedimentological and micropaleontological analysis (larger foraminifera, benthic and planktic microforaminifera, and ostracoda) allows deduce an outer infralittoral environment of deposition for these levels. Larger foraminifera (Heterostegina) could dominate the more oligotrophic depositional conditions during intervals of sea level rise; ostracoda and small benthic foraminifera could dominate preferably the more eutrophic ones during intervals of continental clastic input |
