Summary:The study deals with the upper contact of Qamchuqa Formation with the overlying Bekhme area of northern Iraq. This surface is characterized by presence of autobreccia bed including angular grains of (0.05_30cm in size) and composed of dolomite with disseminated black dolomite fragments which may indicates their subaerial exposure. Cementing materials filled the fractures and pores surrounding the breccias mostly are composed of saddle dolomite with dolomite crystal up to 3cm size that were formed late diageneticly by hydrothermal solution.
