Özet

Ilerdian (early Eocene) carbonates in the northwestern Tosya region, northern Turkey, are characterized by porcellaneous larger benthic foraminifera; Glomalveolina, Alveolina, Orbitolites, Opertorbitolites and Cyclopertorbitolites are common in the southeastern Kastamonu region, in facies deposited on a low-gradient carbonate ramp. The inner ramp comprises of Miliolid-soritid wackestone, Soritid wackestone, Alveolinid-soritid wackestone-packstone, Alveolinid wackestone, Alveolinid-Nummulitid wackestone-packstone, algal wackestone, and Coralline algal pack-grainstone microfacies. The middle ramp deposits are composed of Alveolinid-nummulitid wackestone-packstone and Nummulitid wackestone-packstone microfacies. Overall, the succession reflects a long term deepening trend.
