This paper analyzes the benthic foraminiferal assemblages present in two Upper Tortonian sections belonging to the «Arcillas de Gibraleón» Formation (Guadalquivir Basin) containing a characteristic glauconitic level. The ...

The Guadalquivir foreland basin has a complex temporal and spatial evolution which is shown in its facies architecture and its paleogeographical distribution during Tortonian. In this work we emphasize the control that ...

The passive margin of the Guadalquivir foreland basin records different stages of evolution during the tortonian transgression, mainly determinate by sedimentary supply/ accommodation space ratio (A/S ratio, Cattaneo and ...

The Guadalquivir foreland basin, located between the Iberian basement northward and the Betic orogen to the South, repre¬sents the western sector of the earlier foredeep basin of the Betic Cor¬dillera. Along the northern ...

The Benthic foraminifera of the superficial sediments of several cores from the continental shelf of the north Cádiz Cu If have been analized. The distribution of these organisms shows a clear dependency to the water depth, ...

This paper analyzes the lithostratigraphic features and the ostracode assemblages of the Upper Tortonian deposits located in the central sector of the Guadalquivir basin. Seven facies were defined, being deposited in fluvial ...

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 ...

The study of faunistic associations, ichnology and sedimentology of coastal deposits, that crops out in the central sector of pasive margin of the Guadalquivir Basin, allows us to make an approached reconstruction of ambient ...
