The sedimentary succession consists of two informal units: the conglomerate unit and calcareous unit (Lower and Upper Units).The conglomerate unit is composed with subangular to rounded pebbles of foraminiferal limestone and red chert. A large number of mollusk fragments, mainly gastropods and bivalves were identified. The calcareous unit is composed of thick limestones (wackestone) bearing foraminifera occurring in the lower one-third part of the unit which passes upward into thick gray limestone containing foraminiferal fauna alveolinids and orbitolitids and continues with very thick coral limestones in the middle part of this unit. The upper one-third of the calcareous unit is composed of well-bedded bioclastic gray to yellow wackestone and biomicrosparite which is characterized by the presence of coralline red algae, Nummulites globulus Leymerie and rare miliolids. It continues with gray micritic limestone (packstone to grainstone) defined by the presence of disc-shaped orthophragminids.
