الملخص الإنجليزي

The Ratgah Formation (Eocene) is found extending towards the Southern Desert of Iraq.

This added an important knowledge on the formation's distribution, and basin configuration, which is known to bedominent in western Iraq.

The results of studying the subsurface sections in South Nasirya area, Southern Desert, were an important improvement in the documentation of the presence of the Ratgah Formation.

The age designation and facies analysis were determined, by means of planktonic and larger foraminifera.

Two planktonic foraminiferal zones of Late Lutetian – Early Bartonian (Late Middle – Early Late Eocene) stage is found in this part of Ratgh Formation, they are: 1- Hantkenina alabamensis Zone of Early Bartonian (Early Late Eocene).

2- Acarinina bullbrooki Zone of Late Lutetian (Late Middle Eocene).

The Acarnina bullbrooki Zone is divided into two larger foramininferal subzones, they are: a- Alveolina – Lockhartia Subzone of Late Lutetian.

b- Nummulites bayhariensis Subzone of Late Lutetian.
