A Cenomanian–Santonian rudist–bearing carbonate platform on the northern Arabian Plate, Turkey: facies and sequence stratigraphy

Micropalaeontology, biostratigraphy, and depositional setting of the mid-Cretaceous Derdere Formation at Derik, Mardin, south-eastern Turkey

“…A late Cenomanian-early Turonian global calcisphere bioevent is associated with Ocean Anoxic Event 2 (Hart, 1991;Wendler et al, 2010), with a high abundance of calcispheres recorded during this interval from many Tethyan margins. Mülayim et al (2018Mülayim et al ( , 2020 have previously recorded Pithonella and other calcispheres from the lowermost (not upper) Derdere Formation of the subsurface, in stratigraphic units not seen in our outcrop study. "Calcisphaerulids" (i.e.…”

“…Originally described from the middle to late Cenomanian of Israel (Hamaoui, 1965), the species has sporadically been recorded from the southern Tethyan margin, including records from the late Cenomanian of Morocco (Ettachfini et al, 2005;Lézin et al, 2012) and Tunisia (Abdallah and Meister, 1997), the middle Cenomanian of western Qatar (El Beialy and Al-Hitmi, 1994), the middle and late Cenomanian of Sinai (Shahin and Elbaz, 2013), and the middle and late Cenomanian Mishrif Formation of Kuwait and southern Iraq (El-Naggar and Al-Rifaiy, 1973; Mahdi and Aqrawi, 2014). Özkan and Altıner (2019) did not record this species in their assessment of the micropalaeontology of the Derdere Formation, but it has previously been reported from the Derdere Formation by Mülayim et al (2020). Its presence provides calibration of the biostratigraphy of the larger benthonic foraminifera that co-occur with it (i.e.…”

“…The Cretaceous succession in south-eastern Turkey on the Arabian Plate is composed of the Mardin (Aptian-Santonian) and Adıyaman (Campanian-Maastrichtian) groups (e.g. Mülayim et al, 2020). The Mardin Group represents deposition on a carbonate platform that developed on the passive, northern edge of the Arabian Plate prior to southerly directed thrusting and related folding (Görür et al, 1991;Cater and Gillcrist, 1994).…”

“…Çelikdemir et al, 1991;Görür et al, 1991;Cater and Gillcrist, 1994;Cros et al, 1999;Demirel and Guneri, 2000;Robertson et al, 2016;Mülayim et al, 2016;Özkan and Altıner, 2019) or Albian (Özkan and Altıner, 2019). Others differ on which part of the Cenomanian the formation should be assigned to (compare Mülayim et al, 2018Mülayim et al, , 2020. Whilst most papers agree that the Derdere Formation represents deposition on a shallow marine carbonate platform, deeper water intervals are recognised, sometimes at the base of the formation and sometimes towards the top.…”

“…Görür et al, 1991;Mülayim et al, 2016), notably lacking alveolinid-rich packstones and grainstones. Mülayim et al (2020) studied the Derdere Formation at Sabunsuyu in Kilis province. There, unlike at Derik, the Derdere Formation (68.9 m thick) is rich in rudist bivalves.…”
