Abstract The Krems Embayment contains the westernmost fully marine depositional environments of Karpatian and Bade-nian transgressions in Central Paratethys. Four drill cores were investigated to analyse bio- lithostratigraphic, tectonic relations. core sections cover Laa Formation (bio-zones M4, NN4) Badenian Gaindorf (M5b-M6, NN4-NN5). Important biostratigraphic indicators identified are Prae...

the sarcheshmeh formation is a shaly sequence of lower cretaceous age (aptian) which is deposited in koppeh-dagh sedimentary basin and conformably overlies and underlies the tirgan and sanghaneh formations respectively in the toos well # 1. lithologically, this formation has a thickness of 177m and consists mainly of marl, shale and shaly limestone. palynological studies resulted in identificat...

Abstract The Latest Danian Event (LDE, ~ 62.2 Ma) is characterized by global changes in the carbon cycle as indicated two negative ? 13 C excursions of up to 1‰. These shifts are accompanied a 2–3 °C warming both surface and deep waters based on benthic planktic foraminiferal 18 O measurements, LDE has, thus, been considered so-called hyperthermal event. event lasted for 200 kyr has identified ...
