The Bithynian substage of the Anisian stage (Middle Triassic) was established by Assereto in the Gebze area (Kocaeli peninsula, northwestern Turkey), within the middle member of Nodular Limestone formation, now included in the Tepeköy Formation. The rich

Uppermost Jurassic to Lower Cretaceous benthic foraminiferal biostratigraphy at ODP Site 765 on the Argo Abyssal Plain. [PDF]
Benthic foraminifers were studied in 99 samples collected from the lower 200 m of Hole 765C. The studied section ranges from the Tithonian to Aptian, and benthic foraminifers can be subdivided into five assemblages on the basis of faunal diversity and ...

Stratigraphy and age of the Cappadocia ignimbrites, Turkey: reconciling field constraints with paleontologic, radiochronologic, geochemical and paleomagnetic data [PDF]
The stratigraphy and age of the Neogene Cappadocia ignimbrites (Central Turkey) have been inferred in previous studies from fieldwork and K–Ar age determinations.

ABSTRACT Preserved allocyclic signatures in the rock record often reflect basin‐scale climatic variability and serve as key proxies for correlating ancient dryland successions. The notion of climate cyclicity, however, remains largely untested on regionally constrained, outcrop‐calibrated studies.

Floods are one of the most critical environmental threats in Central Europe. We show the importance of geomorphological records from Ahr flood deposits for reconstructing past high‐magnitude flood events. Our chemolithostratigraphical analysis shows that centennial to millennial scale high‐energy flooding is not the exception but the rule in the Ahr ...

The “Limons des plateaux” formation, in the north of Tours, is a set of loessic deposits from the middle-Weichselian period. Recent excavations of preventive archaeology provided lithic artefacts from Mousterian period on 4 sites and made absolute ...
