In the General Geology and morphology of the North-Eastern Black sea coast near the city of Anapa, flish structures play a significant role. Research flysch formations helps to recreate pala - obotanik in which there was an accumulation of sediment and formation of rocks. The Anapa flysch of the Caucasian type is a sequential interbedding of sandstones, siltstones, and mudstones. The flysch structure has a peculiar structureit includes softer layers of clay minerals that are eroded, leaving protrusions of stronger sandstones. Sometimes oil and mineral water deposits may be associated with the flush. The Caucasian flysch is characterized by large reserves of cement raw materials - upper Cretaceous limestones and marls. In the context of Anapa upper Cretaceous flysch is observed ozelenenie species, as well as meet limonite nodules. Some sections of the section show cracks encrusted with calcite. The paper analyzes the textural and structural features and concludes that the formation of the flish occurred in the lower part of the deep - water drift cone, since there is an interbedding of sandstones and finer-grained clay material throughout the section. The presence of carbonate material indicates a break in the flow of turbidity, and also allows us to determine the sedimentation situation of a warm shallow sea.
