| Abstract | ||
| Qamchuqa Formation rocks are part of eighth cycle of the Arabian plate (AP8). The rock sequences of this cycle deposited in Late Tithonian - Early Turonian. The study based on two surface sections of Qamchuqa Formation in Bekhme and Galala sections Northern Iraq. Qamchuqa Rocks are characterized by their hard and High porosities, and formed of dolostone, limestone and dolomitic limestone. The formation sequences are composed of three main sedimentary facies: limestone facies consists of four microfacies, dolostone microfacies is subdivided into five submicrofacies and lithofacies is subdivided into two lithofacies. The sedimentary model of the formation deduces from the sedimentary facies, It reflects marine depositional environments extending from the fore reef to the tidal flats environments. The reef environment doesn't recorded in the studied section but we can estimated its place near Gali Ali Bek area. | ||
