Los foraminíferos bentónicos del horizonte glauconítico inferior de la Formación «Arcillas de Gibraleón» (Depresión del Guadalquivir, SO España)
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 basal samples of this horizon show both shallow-water and epibathyal taxa, a mi...

| Sumario: | 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 basal samples of this horizon show both shallow-water and epibathyal taxa, a mixture also found in ostracods that may characterize the transition toward deeper conditions. In the upper samples, deepneritic and epibathyal species are dominant, indicating a moderate-deep environment (150-300 m) in which was deposited most of the glauconitic horizon |
