Abstract
A strata of clays and clay aleurolites with olistoliths and olistoplaques is outlined on the seaside in the north-west in the Agoi river valley. Sediments of the strata are composed of grey calcareous clays with layers of aleurolites. The layers and lenses of olistostromes contain small fragments, large blocks and large olistoplaques of various ages. From various layers of strata, from a matrix and olistostoliths a microfauna is selected and defined. Small structural forms (slickensides and tension gashes) were recognized in olistoliths and olistoplaques, which are not traced in the matrix, this indicates that a series of folded and fissured structures were formed before these olistoliths and olistoplaques appeared in the olistostrome strata. Thickness of strata is estimated at 280 m.

Summary
A strata of clays and clay aleurolites with olistoliths and olistoplaques is outlined on the seaside in the north-west in the Agoi river valley. Наиболее молодые отложения выполняют ядерную часть Агойской синклинали (пачки 13–15). Стратиграфически снизу вверх в разрезе агойской олистостромовой толщи выделяются: 4) пачка от т.н. Мощность пачки 25 м; 5) пачка пепельно-серых алевритистых глин от т.н. Мощность пачки 20 м; 6) пачка известковистых глин с олистостромовыми горизонтами от т.н.
