Neogene stratigraphy and gastropoda-pelecypoda fauna of Bolayir-Şarköy-Mürefte (Çanakkale-Tekirdağ) between

In this study, Neogene sediments of around Bolayır-Şarköy-Mürefte are studied and stratigraphy, paleogeography of this levels have been introduced using Gastropoda- Pelecypoda fauna.9 stratigraphic sections taken from study area and 5 genus and 4 species belonging to Gastropoda and 15 genus, 12 species belonging to Pelecypoda are determined in these sections. Gastropod- Pelecypoda faunas taken from measured stratigraphic sections indicate that these levels were formed in the Late Miocene, Late Pliocene (Romanian/Aktschagilian=Kuvalnikiyen) and Late Pleistosen. İt is found that the study area which has same brackish water fauna with Dasic and Caspic basins had been feed by rivers during the Late Pliocene time. In the light of these data, it is find out that the study area is effected by both of Central and Eastern Paratethys during the Late Miocene and Late Pliocene time. Mediterranen is improved to area in Late Pleistosen. It is commented that there was primarily a regression and then a transgression process in Bakunien. As a result of transition of Mediterranean to the region in Late Pleistocene, the study field started to get a marine basin.
