Burdur ve Isparta Arasında Bulunan Üst Tersiyer Denizel Tortul Kayaçlarının Nannofosillerle Biyostratigrafik Çözümlenmesi

Bu çalışmanın amacı Gökçebağ (Burdur) ve Yakaören (Isparta) köyleri arasındaki bölgede yer alan Geç Tersiyer yaşlı denizel kırıntılıların biyostratigrafik çözümlenmesidir. Çalışma konusunu oluşturan denizel tortul kayaçların biyostragrafik çözümlemesinde, eş yaşlı ve taşınmış olarak kökensel ayrımlanmış 93 adet nanoplankton türü tanımlanmış ve kayıtlara dayanarak Isparta Formasyonu’na ait Discoaster saipanensis NP17; Güneyce Formasyonu’na ait Triquetrorhabdulus caritanus NN1, Discoaster druggii NN2, Sphenolithus belemnos NN3 olmak üzere 4 aşmalı menzil zonu belirlenmiştir

Drilling and core data from the Gulf of Gemlik (SE Sea of Marmara): Holocene fauna and flora assemblages

*Yıldız, Ayşegül ( Aksaray, Yazar )This study was conducted to determine fauna and flora assemblages of Holocene sequences from Gemlik Gulf (SE Marmara Sea) and to obtaine their similarities and differences between the assemblages of Gemlik and İzmit Bays. Total of 201 dark gray colored, fine to medium grained sandy clay samples were studied. In the drilled samples, 22 genera and 38 species were identified from the foraminifera characterizing the infralittoral zone. 40 genera and 58 species of foraminifera characterizing the upper circalittoral zone were identified. In addition, Black Sea originated Ammonia parasovica was found for the first time in cores taken from Gemlik Gulf. Nannofossil species characterizing the open-shallow marine environment Emiliania huxleyi, Reticulofenestra parvula, Coronosphaera spp., Syracosphaera spp., Helicosphaera spp. beside Gephyrocapsa oceanica, small Gephyrocapsa spp., Scyphosphaera porosa were obtained. A total of 27 genera and 37 species from ostracods were defined in the samples from gulf. Moreover, the quite abundant mollusc assemblage characterizing the shallow marine environment and fewer genera and species of diatoms were identified. The studied sequence is represented by NN21 Emiliania huxleyi biozone at the Holocene. Foraminifers and ostracods of the Gemlik Gulf are observed as Mediterranean-Aegean Sea originated assemblages. The mollusc shows the shallow marine community
