RISA multi-proxy chemostratigraphy of the Cenomanian/Turonian transition in Kopet-Dagh basin (NE Iran); implication for oceanic temperature and pCO2 variations
In a global scale, the Cenomanian-Turonian boundary event (OAE2) has been characterized by its warm climate interval accompanied by a major sea level transgression. However, chemo- and biostratigraphy studies in the Kopet-Dagh basin (NE Iran...
Planktonic foraminiferal turnover across the Cenomanian –Turonian boundary (OAE2) in the northeast of the Tethys realm, Kopet-Dagh Basin
Two Late Cenomanian – Early Turonian (C–T) intervals of the eastern part of the Kopet-Dagh basin, NE Iran have been investigated to evaluate the response of planktonic foraminifera to the geological event OAE2. The Gharesu and Taherabad sections...
Nitrogen isotope variations and environmental perturbations during Cenomanian-Turonian transition in the NE Tethyan realm, Koppeh-Dagh basin
The Cenomanian-Turonian Gharesu section in the east of Koppeh-Dagh basin have been investigated to determine the relationship between palaeoenvironmental perturbations and nitrogen cycling across OAE2. This succession is composed of 43 m shale...
Paleoenvironmental perturbation across the Cenomanian/Turonian boundary of the Kopet-Dagh Basin (NE Iran), inferred from geochemical anomalies and benthic foraminiferal assemblages
A Cenomanian/Turonian boundary succession in the northeastern Tethyan realm, Kopet-Dagh Basin in
NE Iran, was studied to examine the effects of biological productivity, atmospheric CO2 concentration,
and sea ...
Enhanced chemical weathering and organic carbon burial as recovery factors for the OAE2 environmental conditions: a case study from Koppeh-Dagh Basin, NE Iran
related to the oceanic anoxic event 2 (OAE2). The study succession is composed of dark gray shale and glauconitic sandstone of Aitamir Formation, which is conformably overlain by cream marl and marly limestones of Abderaz Formation. The dark shale...
