Abstract

The existing Late Paleocene-Early Eocene planktonic foraminiferal biostratigraphy of the Indus Basin, Pakistan is reviewed in this paper. The planktonic foraminiferal zones (i.e. P3-E5) of the currently used tropical to subtropical scheme are recognized in these successions, which has helped in the intra-basinal correlation of the Dungan and Shaheed Ghat formations (Lower Indus Basin) with the Patala and Nammal formations (Upper Indus Basin) of Pakistan. The presence of the Late Paleocene-Early Eocene planktonic foraminiferal assemblages (represented by three main genera; Acarinina, Subbottina and Morozovella) in Pakistan attest to the fact that tropical to subtropical warm surface water conditions existed through the Late Paleocene-Early Eocene interval.
