AbstractThe environmental conditions prevailing during sedimentation of the lower Miocene sequence, represented by the Serikagni Formation, the Serikagni/Euphrates intertonguing and the Euphrates Formation, in Jambur well No.18, Northern Iraq are revealed by the interpretation of its foraminiferal fauna. The environmental relationships of the foraminiferal assemblage indicate that the Serikagni Formation was deposited in upper/middle slope, the Serikagni/Euphrates intertonguing in outer shelf and the Euphrates Formation in inner shelf depths. The planktonic foraminiferal fauna recorded in this study is typical Tethyan in composition; its high diversity indicates tropical – subtropical climatic conditions.
