Abstract

The studied surface section of Khurmala Formation which lies in the northeast of Dohuk city north Iraq consists of mixed carbonate and clastic sediments, package about 60 meter thick of Early Eocene age. The carbonate sediment is comprising four microfacies association allocated to shoal bank (Kh2), lagoon (Kh1), intertidal (Kh1, Kh3), and supratidal (Kh4), while the clastic sediment included two lithofacies affiliated to estuaries depositional environment. A depositional model of the Khurmala Formation was proposed.
Diagenetic processes of dissolution and dolomitization are recognized in microfacies (Kh3).
