Türkiye'nin kuzeydoğu kesiminde Selandiyen (Üst Paleosen) bentik foraminifer toplulukları ve stratigrafik dağılımları

Öz

Bu çalışmada,Türkiye’nin kuzeydoğu kesimindeki bazı sığ denizel karbonat istiflerinde Selandiyen’in bentik foraminifer toplulukları tesbit edilmiştir. Bu topluluklardan, Laffitteina erki (Sirel), Kathina selveri Smout, Rotalia trochidiformis (Lamarck) ve Cuvillierina sireli İnan’ın ilk bulunuşları Selandiyen’in alt sınırını belirler ve bunlar Tanesiyen’de de mevcutturlar. Kayseriella decastroi Sirel, Ankaraella trochoidea Sirel ve Thalmannita sp.’nin, Türkiye’nin kuzeydoğu kesimindeki yerel stratigrafik dağılımları ise, sadece Selandiyen’le sınırlıdır
