Microfacies and Depositional Model Jeribe Formation (Early Middle Miocene), Northwestern of Iraq

It appears that the tectonism throughout early middle Miocene played an important role in the variations and distribution of facies zones within Jeribe basin.

Intermittent tectonic uplifts in basement blocks are reflected by successive secondary marine regressions toward the center of the basin in Sheikh-Ibrahim area. However, this regression had led to the termination of the Jeribe successions at studied area. This is represented at study area by a thick development of tidal flat facies overlain by a fresh lake facies at eastern parts; however it is exclusively represented by a thin bed of tidal flat facies at the western parts. ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ
