The Cenomanian/Turonian boundary interval deep-sea deposits in the Zagros Basin (SW Iran): Bioevents, carbon isotope record and palaeoceanographic model

Patterns of planktonic foraminiferal extinctions and eclipses during Oceanic Anoxic Event 2 at Eastbourne (SE England) and other mid-low latitude locations

“…Planktonic foraminifera underwent a turnover across the Cenomanian-Turonian boundary interval with the isochronous extinction of several single-keeled rotaliporids at the onset of OAE 2 and the more gradational evolution and diversification of partially (Praeglobotruncana), double-and single-keeled (Dicarinella and Marginotruncana) taxa (e.g., Premoli Sliter, 1995, 1999;Hart, 1999), resulting in a biostratigraphicallyrelevant sequence of events that can be used to improve the resolution of the current biostratigraphic schemes and the accuracy of correlations. Moreover, planktonic foraminifera are often absent in the organic-rich layers deposited during OAE 2, or they are indicative of reduced thermal stratification and increased sea-surface productivity (Leckie, 1985(Leckie, , 1987Leary et al, 1989;Lamolda et al, 1997;Leckie et al, 1998Leckie et al, , 2002Huber et al, 1999;Nederbragt and Fiorentino, 1999;Paul et al, 1999;Keller et al, 2001Keller et al, , 2008Keller and Pardo, 2004;Coccioni et al, 2006;Grosheny et al, 2006Grosheny et al, , 2013Kalanat and Vaziri-Moghaddam, 2019, among many others).…”

“…The record of planktonic foraminiferal extinctions at Eastbourne is compared with other low to mid-latitude sections including Pont d'Issole (Grosheny et al, 2006) and Clot Chevalier (Falzoni et al, 2016a) in SE France, Ganuza, Spain (Lamolda et al, 1997), Tarfaya, Morocco (core S57, Tsikos et al, 2004, Falzoni et al, 2018, Lar Anticline, Iran (Kalanat and Vaziri-Moghaddam, 2019), and Pueblo, Colorado (Leckie, 1985, Leckie et al 1998Keller and Pardo, 2004;Desmares et al, 2007Desmares et al, , 2008Elderbak and Leckie, 2016), with the aim to understand if extinctions were controlled by local conditions or if they resulted from wider scale environmental perturbations (Fig. 3).…”

“…4). This was contemporaneous with the renewed development of intrashelf basins in SW Iran and the recognition of a d 13 C isotope excursion within basinal facies of the Sarvak Formation (Vincent et al, 2015;Kalanat and Vaziri Moghaddam, 2019) (see Fig. 9, Khormuj and Chenar Bashi outcrops).…”

“…Kennedy and Simmons, 1991), the Sarvak Formation of Iran (e.g. Adams et al, 1967;Kalanat and Vaziri-Moghaddam, 2019) and the Derdere Formation of SE Turkey (e.g. .…”

“…In this regard, we compare the δ 18 O vs δ 13 C results with oxygen and carbon isotope data of the lacustrine carbonates deposited in the Seymareh River basin (Al-Aasm et al, 2009;Navidtalab et al, 2016;Kalanat and Vaziri-Moghaddam, 2019;Jafari et al, 2020;Razmjooei et al, 2020aRazmjooei et al, ,b, 2021 (Fig. 11), and the δ 18 O concentrations with the grain classes (sand, and clay) (Fig.…”
