ABSTRACT
Quantitative studies of benthonic foraminiferal
assemblages of nine boreholes samples provide data by which
the environments that prevailed during their life history
are reconstructed. The boreholes (35 – 48 m depth) are
distributed in the region of El Arish – Zewied.- . Rafah
at the northeastern coast of Sinai Peninsula. Egypt. The
prevailing environments were: near shore shelf at the basal
part of the succession followed by hyposaline lagoon which
was restricted at El Arj5h – Zewied area, the succession
was terminated by nonmarine environ~nt at the extreme
eastern and western parts of the area. CO”relation among
the different boreholes was attempted and a paleogeographic
map for the area was prepared to demonstrate the verticaland lateral distributions of the different reconstructed
envi ronments.
