Ostracoda and Foraminifera Assemblages of the Lower-Middle Miocene Reefal Carbonates within the Değirmençay Area, NW Mersin/S Turkey

Öz

The occurrence and development of reefal carbonates depend on biological activity and depositional conditions. Besides of fossil assemblages, it is also critical to determine depositional parameters of environment such as sea level change, substratum or clastic input.  This study is realised on an important reefal carbonate units as known the Kaplankaya and Karaisalı formations in the Değirmençay locality of Mersin Province, Mediterranean. In this study, the ostracod and foraminifer assemblages were determined in the samples collected from reefal carbonate units of the Early-Middle Miocene age.  The base of the investigated area consists of Upper Cretaceous ophiolite and Upper Cretaceous-Palaeocene ophiolitic mélange. These units are unconformably overlain by Miocene sediments. This study determine ostracod and foraminifera assemblages of the Early-Middle Miocene reefal carbonate system. While abundance ostracod species were observed at the reefal carbonate levels, also a few planktonic foraminifer species. As a result of paleontological studies, 12 genera and 15 species from Ostracoda, 3 genera and 3 species from planktonic foraminifera have been determined. The Ostracoda species (Aurila soummamensis, Hemicyprideis villandarutensis), and planktonic foraminifer species (Globigerinoides trilobus, Globoquadrina dehiscens and Orbulina universa) point out that these reefal carbonates deposited at the Early-Middle Miocene time interval.

Değirmençay Bölgesindeki Alt-Orta Miyosen Resifal Karbonatların Ostrakod ve Planktonik Foraminifer Topluluğu, KB Mersin/G Türkiye

Öz

Resifal karbonatların oluşumu ve gelişimi büyük ölçüde biyolojik aktivite ve çökelme ortam koşullarına bağlıdır. Bu nedenle resifal karbonatların oluşum ve gelişimini anlayabilmek için fosil toplululuğunu ortaya koymak, çökelme ortam koşullarını yansıtan deniz seviyesi, deniz tabanı ve klastik girdisini bilmek kadar önemlidir. Bu çalışma Akdeniz’de önemli bir resifal karbonat sistemi olan Kaplankaya ve Karaisalı Formasyonları üzerinde yürütülmüştür. Çalışma bölgesi Mersin İli’nin kuzeybatısındaki Değirmençay ilçesinin çevresinde yer almaktadır. İnceleme alanının tabanı Üst Kretase ofiyolitleri ve Geç Kretase-Paleosen yaşlı ofiyolitik melanjden oluşmaktadır. Bu birimler uyumsuz olarak Miyosen çökelleri tarafından örtülür. Bu çalışmada, Erken-Orta Miyosen resifal karbonat sisteminin ostrakod ve foraminifer toplulukları belirlenmiştir. Bu çalışmaların sonucunda resif düzeylerinde tespit edilen ostrakod içeriğinin planktonik foraminifer içeriğine göre daha fazla olduğu gözlenmiştir. Paleontolojik çalışmalar sonucunda, ostrakodlardan 12 cins ve 15 tür, planktonik foraminiferlerden ise 3 cins ve 3 tür tespit edilmiştir. Ostrakodlardan Aurila soummamensis ve Hemicyprideis villandrautensis ve planktonik foraminiferlerden Globigerinoides trilobus, Globoquadrina dehiscens ve Orbulina universa gibi türler bu resifal karbonatların Erken-Orta Miyosen zaman aralığında çökeldiklerini göstermektedir.
