Agedabia formation and the environmental implication of its biota at garyounis, sw benghazi.

The main aim of this paper was to study the Quaternary Agedabia Formation in Garyounis area; this study is based on different paleontological evidences to deduce the various environmental conditions. One lithostratigraphic section have been measured and investigated. It consists mainly of calcarenite and clay. The thickness of the section is 2 m along the mouth of Wadi Al Qattarah at Garyounis area, SW Benghazi city. A number of samples have been studied and about 13 species of fauna and flora have been identified. They include three foraminifera, four bivalves, four Ostracodes, one gastropod and unidentified Bryozoans specimen have been observed also. The cement type (isopachous) of the studied section is confirming that the calcarenite is of subaqueous or marine in origin. The studied calcareous algae plus the associated foraminifer’s points that the calcarenite was deposited under fairly warm (15-30oC) shallow marine conditions with a suggested bathymetric range between 030m.
