Abstract

Three formations were studied from seven outcrops extend from Surdash to
Shaqlawa (Cenomanian – Santonian), they comprise Dokan, Gulneri and Kometan
Formations. Four microfacies and eight submicrfacies are identified depending on
this microfacies, we determine the depositional environments. Dokan Formation is
deposited in open-marine deep shelf environment; it could be deposited at deeper
shelf to slope and basinal settings. While Gulneri Formation deposited in open sea
shelf, as well as at outer shelf settings, the sediments consist of organic–carbon rich
black shale and consider a record of the ocean anoxic event 2, Kometan Formation
represent pelagic sediments characterize the deep-marine basins in open marine.
