In this research, biostratigraphy related to the carbonate succession of the Shahbazan Formation at the southeastern flank of Chenar anticline, Lurestan Basin, is discussed. A study of large benthic foraminifera from the 294 mthick Shahbazan Formation led to the identification of two Middle Eocene biozones: Somalina sp. Zone, Nummulites-Alveolina Assemblage Zone. The age of the Shahbazan Format...

This research focusses on the biostratigraphy and paleoecological implications of the carbonatesof the Asmari Formation. The Asmari Formation is located in the Siah Kuhanticline of Izeh, Zagros Basin, SW Iran. It is of Late Oligocene (Chattian) - Early Miocene (Burdigalian) age. In this stratigraphic section, the Asmari Formation overlies the Pabdeh Formation and underlies the Gachsaran Formati...

The Central Iran Basin is a region with unique environmental characteristics in which the Late Paleogene–Early Neogene benthic foraminifera display distinctive distributions and abundances that can assist identifying intervals best reservoir potential. Lipidocyclinid miogypsinid zonal marker taxa this be correlated those SBZ23 (European Basin), indicating an Oligocene (Chattian) age. With sedim...

Current global warming is likely to result in a unipolar glaciated world with unpredictable repercussions on atmospheric and oceanic circulation patterns. These changes are expected to affect seasonal extremes and the year-toyear variability of seasonality. To better constrain the mode and tempo of the anticipated changes, climatologists require ultra-high-resolution proxy data of time interval...

Abstract Jurassic carbonate strata in the eastern Paris Basin exhibit several generations of faults, tension gashes and stylolites. Although their relative chronology can sometimes be determined according to cross-cutting relationships, duration major deformation phases influence on fluid flow cementation are still uncertain. This contribution aims clarify timing brittle associated calcite ceme...

The Oligocene (Rupelian) Byram Formation (Vicksburg Group) in Alabama, USA, is divided into three members, including (in ascending order) the Glendon Limestone, unnamed marl, and Bucatunna Clay. The marine units Alabama have been historically under-investigated, but bulk samples recently obtained from Limestone Member exposures at site AWa-9 Washington County yielded 20 unequivocal elasmobranch...
