英文摘要	The Selandian-Thanetian (S/Th) succession is extensively represented and well exposed along the eastern escarpments of the Kharga Oasis, Western Desert, encompasses the upper part of the Dakhla Formation, Tarawan Formation and the lower part of the Esna Formation. This study based on the qualitative and quantitative investigation of the planktonic and benthic foraminiferal assemblages aims to assess and specify the S/Th transition in terms of the biostratigraphic, paleoecologic and sequence stratigraphic analyses. The studied interval is subdivided into three 3rd order depositional sequences (Seq. 1, Seq. 2 and Seq. 3) separated by two sequence boundaries at the Dakhla/Tarawan (SB 1) and the Tarawan/Esna (SB 2) contacts, respectively. The S/Th boundary is placed at the Maximum Flooding Surface (MFS) of the second depositional sequence (Seq. 2) within the Tarawan Formation and lies at about 6 m above the base of a distinct thin layer related to the Mid Paleocene Biotic Event (MPBE). The S/Th MFS is characterized by a relatively highest positive peak in the P/B ratio (90%) and the common occurrence of the bathyal benthic taxa. The reported MFS displays great correspondence with the eustatic sea -level related to the timing and extent that can be treated as a secondary criterion relevant for delineating and correlating the Selandian-Thanetian transition everywhere.
