| From Wamas et al. 2020: James and Slaughter (1974) studied the type section of Gar El-Muluk and gave it the Upper Pliocene age. Philip et al. 1975 assigned it to Upper Pliocene age based on its fossils and stratigraphic position. Also, Abu Zeid (1984), Abdullah (1996), El-Shahat, et al. (1997) suggested an Upper Pliocene age for the Muluk Formation. In the present study, Upper Pliocene age is adopted for the El-Muluk Formation. | Green, sandy micaceous shales. The formation consists of 35 m (115 ft) of shales, calcareous sandstones and thin limestone beds. It has been assigned a lower to upper Pliocene age. The succession includes, in an ascending order: 1) black carbonaceous shales, GREEN SANDY MICACEOUS SHALES; 2) cross-bedded sandstones and shales; 3) a 30 cm thick bed of calcareous sandstones; 4) a 10 m interval composed of green sands and shales; 5) a 10 cm limestone bed; 6) dark shales and green gypsiferous sands with chert pebbles and gypsum breccia. | Collection based on taxa listed in text as typical of formation. Includes only one mollusca, although plant fragments and fish bones are also mentioned. |
