Comparison of deep-water agglutinated foraminifera from the hemipelagic variegated shales (Lower Turonian-Lower Santonian) and turbiditic Godula beds (Upper Santonian-Campanian) in the Lanckorona-Wadowice area (Silesian Unit, Outer Carpathians, Poland)

Deep-water agglutinated foraminifera (DWAF) have been studied from variegated shales and Godula beds exposed in the vicinity of Kalwaria Zebrzydowska (Silesian Nappe, Outer Carpa- thians, Poland). Following the standard foraminiferal zonation scheme of Geroch & Nowak (1984), the studied variegated shales can be correlated with the Uvigerinammina jankoi Zone (Lower Turonian-Lower Santonian). The Godula beds can be correlated to the Caudammina gigantea Zone (Upper Santonian-Campanian). Foraminiferal assemblages from the variegated shales are dominated by infaunal and semi-infaunal forms. Their occurrence suggests aerobic bottom water conditions associated with low organic matter availability during the deposition of this unit. Such conditions are presumably related to slow sedimentation rate in low energy, well-oxygenated and oligotrophic bottom environment. In contrast, foraminiferal assemblages from the Godula beds are dominated by epifaunal forms, which collected food from the sediment/water interface. It may suggest that sedimentation took place under relatively higher energy conditions with a higher organic matter flux.
