Sedimentary Facies and Foraminifera of the Miocene Carbonates of the Ar Rajmah Group in Cyrenaica, NE-Libya

Abstract

The Miocene carbonates from two different localities of the Ar Rajmah Group have been investigated and examined in the southeast of Binghazi. Based on microfacies analysis and associated benthic foraminifera recovered from the washed residues, the sediments are classified into Wilson’s standard microfacies carbonate facies belts. In these shallow marine belts, 10 different microfacies have been distinguished and described. The sediments of the Ar Rajmah Group were deposited under open platform (Binghazi Formation), restricted platform and restricted lagoon-salina conditions (Wadi al Qattarah Formation) respectively. Biostratigraphic details are excluded due to the lack of age diagnostic-taxa.  However, an attempt to correlate the studied outcrops with the Middle and Late Miocene deposits has been outlined.
