Abstract :

In order to identification of sedimentary facieses and reconstruction of paleoenvironment of Abderaz Formation, an outcrop of this formation near the Padeha Village, East of Kopet - Dagh basin was selected and studied. The Abderaz Formation with the age of Turonian – Santonian that composed of intercalation of shale, marl and chalky limestone, is extended throughout the Kopet – Dagh sedimentary basin. Field and lab scrutinizes are led to recognition of two major terrigenus and carbonate sedimentary facieses that belong to open marine environment. Presence of some bioturbated structures specially in carbonate parts, periodic and suddenly changes in its sedimentary facieses present unstable base for sedimentary basin. Gradual changes in rate of limestone and increase of macrofossil shells thickness from the base to top of the Formation represent warming up the environment in this time.
