Abstract

The Abtalkh Formation is one of the thickest Cretaceous lithostratigraphic units of the eastern Kopet-Dagh Basin, is composed of light gray, green to bluish marl and silty marl. The Abtalkh Formation conformably overlies the Abderaz Formation contains of marls and chalky limestones and it is conformably overlain by the Nayzar Formation (sandstone, silty marl and limestone). Abtalkh Village section contains very abundant, rich and good to moderately preserved Calcareous nannofossil assemblages of Tethyan affinity. A total 468 sample in Abtalkh Village stratigraphical section, representing the oldest and youngest strata of Abtalkh, upper most of Abderaz and base of Nayzar successions, were collected. The thickness of Abtalkh Formation in Abtalkh Village stratigraphical section was measured 1759. 5 (m). One hundred eight nannoplanktonic species belonging to fifty one genera and fourteen families were identified. The biostratigraphic study allowed the recognition of the Calcareous nannofossil biozones of Sissingh (1977), emended by Perch-Nielsen (1985) and Burnett (1998). From bottom to top, biozones CC20, CC21, CC22, of CC23a and UC15bTP, UC15cTP, UC15dTP and UC16 were identified in Abtalkh Village stratigraphical section. The results indicate that the age of Abtalkh Formation in Abtalkh Village section spans from late Early Campanian to Latest Campanian.
