ABSTRACT: This paper investigates
the biostratigraphy of the Palaeocene-Lower Eocene sequences in the Bibi Hakimeh 2 subsurface/subterranean
sections located in the Bibi Hakimeh Oil Field. The Palaeocene-Lower Eocene sequences are
induced as part of the Pabdeh Formation. They are 49 m in thickness and are made up of clayey limestone
with chert intercalations. Biostratigraphic investigations identified 10 genera
and 51 species of Planktonic Foraminifera which with respect to the specific
planktonic species and according to the newest Wade Biozonation led to the
determination of 9 biozones and 4 subzones. The Palaeocene-Early Eocene
biostratigraphic boundary determined previously in accordance with the Wynd Biozonation was reviewed
with respect to the new biozonation. Moreover, the impression of the PETM on the Planktonic Foraminifera found in the Bibi
Hakimeh subsurface section, has
been occurred at P/E boundary on global scale was studied. Based on this research
we can conclude the P/E biostratigraphic boundary border is occurred ranges
between 2125 - 2124 meters in Pabdeh
formation.
