Sažetak
The evolution of the Ottnangian lake was related to synsedimentary tectonics. The first phase consists of the fine-grained swamp deposits, overlain by carbonate deposits of the lake margin, and marls and thin turbidites of a deeper lake realms. These sediments reflect continued tectonic subsidence and deepening. The second phase shows a coarsening-upward trend with an increase of the proportion of clastic deposits, reflects delta progradation, and may be interpreted as a consequence of a relative tectonic quiescence. The third phase includes very silty marls and turbidites, and indicates renewed tectonic activity and deepening. Marine transgression in Karpatian, which terminated the evolution of the lake, is explained by the opening of the connection with Mediterranean sea due to tectonic subsidence.
