Among the Tethyan larger porcelaneous foraminifera widespread from middle–late Eocene to middle Miocene, Austrotrillina Parr, 1942 is only genus showing a non-homogeneous shell structure. This consists of parakeriotheca, coated by thin, dense tectum. Four species (A. brunni, A. eocaenica, howchini, striata) have been often used as biostratigraphical markers in Mediterranean and Indo-Pacific are...

New insights into the geodynamic evolution, paleogeographic framework and paleoclimatic setting of Upper Eocene-Oligocene lacustrine basins from South-East France have been provided by an integrative approach combining geochronology, micropaleontology stable isotope analyses. UPb dating on calcite, pollen-based climatostratigraphy strontium sulfur signatures sulfates a robust chronostratigraphi...

the asmari formation at nil anticline area has been studied in order to determine faunal assemblages, the age and the paleoecology. paleontological and biostratigraphical studies led to the identification of 5 faunal assemblages. as a result, the age of the asmari formation in this section, with 291m thickness, is rupelian/chattian-burdigalian. extension of the large benthic foraminifera sugges...

the asmari formation was deposited in the foreland basin of southwest iran (zagros basin). carbonate sequences of the asmari formation consist mainly of large benthic foraminifera along with other skeletal and non-skeletal components. three assemblage zones have been recognized by distribution of these large foraminifera in the study area that indicate oligocene age (rupelian-chattian). absence...

In this research, biostratigraphy and paleo-ecological reconstruction of the Qom Formation deposits in Bijegan village, northeast ofDelijan, are discussed. The studied section is situated in the western margin of the Urumieh-Dokhtar magmatic arc (the intra-arc basin).The Qom Formation deposits at the studied area are Rupelian-Chattian in age. Larger benthic foraminifers are used for biostratigr...

Abstract The early exhumation history of the Tauern Window in European Eastern Alps and its surface expression is poorly dated quantified, partly because thermochronological provenance information are sparse from Upper Austrian Northern Alpine Foreland Basin. For first time, we combine a single‐grain double‐dating approach (Apatite Fission Track U‐Pb dating) with trace‐element geochemistry anal...
