Stratigraphy and larger foraminifera of the Eocene shallow-marine and olistostromal units of the southern part of the Thrace Basin, NW Turkey

Öz:

Trakya Havzası (KB Türkiye) güneyindeki denizel Eosen birimleri stratigrafik konumları tartışmalı platform ve derin-denizel türbiditik ve olistostromal istifleri ile temsil edilir. Havzanın güneyinde, foraminifer ve/veya foraminifermercan- kırmızı alg bakımından zengin birimlerde yaptığımız çalışmalar ilk kez bu birimler için yüksek çözünürlü biyostratigrafik bir sistemin oluşturulmasına imkan sağlamıştır. Paleontolojik veriler ve arazi gözlemleri ışığında stratigrafik olarak Soğucak Formasyonu’nun altında daha önce Trakya’da tanımlanmamış erken Geç İpreziyen−? Orta Eosen yaşlı sığ- ve derin-denizel bir istifin, Dişbudak istifi, varlığı ortaya konmuştur. Önceki çalışmalarda Soğucak Formasyonu içinde değerlendirilen, bu birimin sığ-denizel kısmı SBZ 10’u (erken Geç İpreziyen) temsil eden orthophragmines, nummulitid ve alveolinid grupları içerir. Yama resifi düzeylerinin yaygın olarak gözlendiği Soğucak Formasyonu orthophragmines (Discocyclina, Orbitoclypeus ve Asterocyclina), nummulitid (retikule ve diğer Nummulites grupları, Assilina, Operculina, Heterostegina ve Spiroclypeus) ve diğer bentik foraminifer grupları (Silvestriella, Pellatispira, Chapmanina, Orbitolina, Linderina, Gyroidinella, Fabiania, Halkyardia, Eoannularia, Sphaerogypsina, Asterigerina, Planorbulina ve Peneroplis) içerir. SBZ 15/16, 17, 18, 19 ve 20 sığ bentik zonları temsil eden bu topluluklar birimin çökelimi ile ilgili denizel olayların kronolojisinin oluşturulmasını sağlamış olup dört önemli dönem; Geç Lütesiyen, Erken Bartoniyen, Geç Bartoniyen ve Priaboniyen transgresyon dönemleri ortaya konmuştur. Çengelli fliş istifinin yaygın kireçtaşı olistolitleri (çoğunluğu Soğucak Formasyonu’ndan aktarılma) ve kısmen türbiditik seviyelerinde ise (geç) Bartoniyen ve Priaboniyen grupları tanımlanmıştır.
