Mishash Formation (Israel)

The Mishash Formation is a Late Cretaceous (Campanian-Maastrichtian) geologic formation in Israel. The formation is correlated with the Duwi Formation of Egypt and the Amman and Ruseifa Formations of Jordan.[1] Mosasaur fossils assigned to Prognathodon currii and pterosaur fossils have been recovered from the formation.

Stratigraphy

[edit]

The lower boundary of the Mishash Formation lies atop the top of the underlying Menuha Formation, while the upper boundary is covered by the overlying Ghareb Formation.[2][3] The Mishash Formation is divided into two members known as the Chert Member and Phosphate Member, with the latter overlying the former.[4] Massive chert beds comprise the Chert Member, while the Phosphate Member is made up of cherts, phosphorites, porcellanites and organic-rich carbonates.[2] The Phosphate Member is further divided into three units; the Phosphatic Carbonate Unit lies at the bottom of the member, followed by the Porcelanite Unit in the middle, and finally the Phosphorite Unit at the top.[3]
