Jeribe Fm

Period: 
Neogene

Age Interval: 
Langhian, Iq (2,3), Sr1


Province: 
Iraq, Syria

Type Locality and Naming

Column: Central Iraq, Rutba Uplift (W Iraq), Syria

Synonym: Basal Fars Conglomerate, Euphrates limestone


Lithology and Thickness

Comprises recrystallized, dolomitized, generally massive limestones; in beds 1-2m thick. In the Euphrates Valley the formation comprises disharmonically folded conglomerates, sandy recrystallized limestones, silicified limestones, and some marl. 70m at type section. In NE Jordan, this formation reaches a thickness of 73 meters, and is covered on top by a 15m layer of gravel. Generally massive, recrystallized, dolomitized limestone with beds of thickness from 1 to 2m.


Lithology Pattern: 
Dolomitic limestone
