Abstract

We provide a stratigraphic correlation between sixteen valleys in the Daryanah Al Abyar area. These valleys are located in the northwestern part of Jabal AL Akhdar, northeast Libya and this study area covers 192.5 km2. These valleys expose marine rocks within seven rock units. From the oldest to youngest these are the Apollonia, and Dranah Formations (Eocene), the Al Baydah Formation, the Algal Limestone, and Shhate Marl member (Oligocene), the Al Faydiah Formation (Oligo-Miocene), and the Al Rajmah Group comprising the Benghazi and Wadi Al Qattarah Formations (Miocene).

Most of the formations and their respective members aforementioned are marine sequences. Additionally, Quaternary deposits cover a large part of the study area and they disconformably overlie the Tertiary rocks that occur on the plateau, escarpment, and on the floor of all valleys.

The aim of our stratigraphic study is to determine the boundaries between these rock units. In the northeastern part of the study area the rock units represent the Apollonia Formation, while in the southern part, this formation is missing but younger formations are present. In addition, this correlation is based on the lateral facies analysis between the marine rock units.
