[1] We explore the applicability of paired Mg/Ca and O/O measurements on benthic foraminifera from Southern Ocean site 747 to paleoceanographic reconstructions on pre-Pleistocene timescales. We focus on the late Oligocene through Pleistocene (27–0 Ma) history of paleotemperatures and the evolution of the dO values of seawater (dOsw) at a temporal resolution of 100–200 kyr. Absolute paleotempera...

The paleoenvironmental impact of the early Aptian Ocean Anoxic Event 1a (OAE 1a, ca. 121 Ma) has been investigated in detail Cismon Core (Lombardy Basin, western Tethys) by using different geochemical and micropaleontological proxies. We provide first high-resolution data benthic foraminiferal assemblages through upper Barremian - lower stratigraphic interval. Benthic foraminifera are integrate...

Introduction Conclusions References

in this study biostratigraphy of the upper cretaceous deposits (gurpi formation) in sepidan section located in the interior fars basin (sw iran) was studied. the gurpi formation in this section consists of 360 m lime shale, argillaceous limestone and shale laid continuously on the ilam formation and with a paraconformity under the pabdeh formation. nine genera and 27 species of planktonic foram...

The seabed of the Pontine Archipelago (Tyrrhenian Sea) insular shelf is peculiar as it characterized by a mixed siliciclastic–carbonate sedimentation. In order to reconstruct Late Quaternary paleoenvironmental evolution Archipelago, this study investigates succession facies recorded two sediment cores. For purpose, benthic foraminifera and rhodoliths assemblages were considered. cores (post-Las...

[1] Core top samples from Indonesian and northeast Atlantic depth transects were used to calibrate Mg/Ca and dO in tests of the calcitic benthic foraminifer Hyalinea balthica to bottom water temperature between 4°C and 13°C. This shallow infaunal species is primarily abundant in neritic to upper bathyal sediments (<600 m). Both linear and exponential calibrations suggest a temperature sensitivi...

A Valanginian to Barremian bathyal foraminiferal assemblage (118 taxa belonging to 51 genera) is documented from ODP Site 766, drilled near the foot of the Exmouth Plateau off northwest Australia. The majority of taxa are cosmopolitan species previously described from the boreal assemblages of northern Europe and the northern margins of the Tethys, but 32 taxa could not be assigned to previousl...
