Research Article Keywords: ABSTRACT Thrace Basin, Oligocene, Aim of the study is to evaluate the Paleogene-Neogene sequences of Babaeski- Lüleburgaz- Late Miocene–Pliocene, Ostracoda, Lignite, Muratlı-Çorlu (Southeastern Thrace, Turkey) region using the micropaleontological analysis on Paleoenvironment two borehole samples collected by Mineral Research and Exploration (MTA), measured sections and point samples taken from the neighborhood of Silivri, Türkmenli-Çorlu, Babaeski-Lüleburgaz, Edirne –Babaeski regions and Tekirdağ-Hayrabolu road. There the lignite sandstone, siltstone (Early Oligocene aged Danişmen Formation) and silts (Late Miocene-Pliocene aged Ergene Formation) with well-preserved ostracod fauna obtained from the the upper levels of the sequence along with some micro-Mollusca at some levels. The study results showed that lacustrine and lagoonal ostracods including marine species were generally found in the claystone, siltstone and marl of the lower and upper levels of lignite cuts in borehole. The ostracod assemblages identified in the study were compared with other ostracod studies in the Thrace Basin and other parts of Turkey as well as in the Oligocene in Paris, the Akiten Basin, Belgium. In the Early Oligocene sediments, the presence of the Tethys effect was observed in the investigated area. In addition, the ostracod species defined in the Late Miocene-Pliocene are compared with other ostracod studies carried out in the Thrace Basin and other parts of Turkey as well as in the Western and Eastern Carpathians, Caspian Basin and Received Date: 14.07.2018 Baltic Sea. According to obtained fauna, the Paratethys effect was determined more than in Tethys Accepted Date: 13.11.2018 in Late Miocene-Pliocene in the studied region. 1. Introduction accomplished in the regions above. During this study, twenty three of the ostracod samples were taken from In the southeast of Thrace Basin, this research, the Danişmen Formation and five of them were taken which is mainly used from Tertiary (Paleogene- from the Ergene Formation. In this study, species Neogene) stratigraphy, ostracod assemblage is as found in the Oligocene include ostracods Neocyprideis follows; the study was conducted in the neighborhood apostolescui, N. williamsoniana, Cladarocythere of Çorlu-Muratlı-Lüleburgaz-Babaeski region in apostolescui, Cytheromorpha zinndorfi, Hemicyprideis southeastern Thrace (Figure 1). The aim of this elongata, H. helvetica, H. montosa, Cytheridea study is to identify the micropaleontological features crassa, C. pernota, Sphenocytheridea gracilis, and an environmental condition of the Paleogene- Serrocytheridea eberti, Krithe angusta, Cushmanidea Neogene rocks of the Çorlu-Muratlı-Lüleburgaz- scrobiculata, Loxoconcha sp.1, Loxocorniculum Babaeski-Malkara and Silivri regions.

During boehli, Virgatocypris tenuistriata, Novocypris striata, all the sampling, particular attention was given to Verticypris jacksoni, Cypridopsis soyeri and Eucypris layers with fossils and lithology types. The washing pechelbronnensis; gastropods; and micro-pelecypods method was used for a total of 153 samples taken (Valvata, Viviparus and Avimactra). In addition, from the measured sections, spot samples and drilling Eucypris dulcifons, Heterocypris salina, Ilyocypris samples for that reason. Samples were disaggregated bradyi, and Candona (Caspiocypris) alta, they were in the laboratory in order to obtain loose Ostracoda identified in between Late Miocene–Pliocene. specimens. Hard samples and samples with medium hardness samples were split into 150 g. batches and 2. Material and Methods wrapped with thick paper for being crushed by using a rock hammer. Crushed samples were then placed During the study, measured sections, spot samples into 1 L glass beakers and treated with hot water and and washed cutting samples of the two boreholes 15% diluted hydrogen peroxide (H O ) for at least completed by the Mineral Research and Exploration 2 2 24 hours. Disaggregated residues were later washed General Directorate were taken from the most over a mesh of 0.60,0.120, and 0.230 mm sieves, and important unit of the area, the Danişmen Formation and the unconformably overlying Ergene Formation. placed in sample bags upon oven drying. Following A total of 22 ostracod genera and 28 ostracod species the separation of microfossils from grains, Ostracoda were identified in the sections, spot samples and were placed on
