Abstract

The  present  research  is  comprised  of  detail  foraminiferal  based  biostratigraphy  and  paleoenvironmental understandings of Shekhan Formation (Early-Middle Eocene) Panoba section  Pakistan.  The  foraminiferal  studies  exhibited  detail  for  biostratigraphy  which  resulted  in  the  interpretations  of  three  planktonic-foraminiferal-biozones.  Identified planktonic-foraminiferal-biozones  include;  (i)  Nummulites  globules  (lower  Eocene),  (ii)  Nummulites  perporatus  Biozone  (middle  Eocene),  and  (iii)  Nummulites  aturicus  (middle  Eocene).  Furthermore,  correlation  of  planktonic-foraminiferal-biozones  with  standard  planktonic zonations have been done. In conclusion, various larger benthonic and smaller foraminifers  of  Lower-Middle  Eocene  interval  have  been  identified. With  the  help  of planktonic-benthonic  ratio,  the  total  foraminiferal  abundance  and  their  diversification/preservation shallow to nerritic inner shelf environmental setting has been interpreted for Early-Middle Eocene Shekhan Formation.
