摘要

Sogucak组始新世中上部至渐新世下部Kazandre石灰岩段在色雷斯盆地广泛分布，富含浅水海洋有孔虫。这里描述的非常浅水的普里abonian相包括Borelis vonderschimitti、Borelis laxipira sp.nov.、Chapmanina gassinensis、Chapmania细长sp.nov..、Pfendericonusglobulus sp.novs.、Orbitolites minimus、Coscinospira sp.上述普里abonion物种的最后出现和浅水海洋卢比安物种Nummulites fichteli的首次出现，瓦库斯Nummulites vascus和平坦Operculina complanata确定了色雷斯盆地东北部新卡赞德雷段的始新世-渐新世边界。

Foraminifera of shallow and very shallow facies from the upper Eocene–lower Oligocene Kazandere Member, Soğucak Formation, Thrace Basin, northwest Turkey

The middle−upper Eocene to lower Oligocene Kazandere Limestone Member of the Sogucak Formation is widely represented in the Thrace Basin and rich in shallow-water marine foraminifera. Very shallow-water Priabonian facies described here include Borelis vonderschimitti, Borelis laxispira sp. nov., Chapmanina gassinensis, Chapmanina elongate sp. nov., Pfendericonusglobulus sp. nov., Orbitolites minimus,Coscinospira sp. Last occurrences of the aforementioned Priabonian species and first appearances of the shallow-water marine Rupelian species Nummulites fichteli, Nummulites vascus and Operculina complanata define the Eocene−Oligocene boundary in the new Kazandere Member at the northeast Thrace Basin.
