Cyclicity in evolution of the Neogene North Croatian Basin (Pannonian Basin System)

Sedimentary succession of the Neogene North Croatian Basin is a result of very complex basin evolution. Since formation of the basin was generated by continental rifting process, tectonic and thermal subsidence strongly controlled sedimentation. A position of the basin within Central Paratethys provided specific influence of global sea-level changes because connection of the Central Paratethys with the Mediterranean and Indo-Pacific Ocean was several times established and ceased ending with total basin isolation. The consequence was evolution of fresh-water, marine, brackish, and fresh-water environments at its end. The evolution of the basin represents a first-order cycle which comprises three second-order cycles separated by major regional unconformities. Six third-order cycles can be distingueshed. They show a transgressive-regressive tendency as a result of very complex interaction of tectonic uplifting and subsidence, global and regional sea-level changes, thermal subsidence, change of climate, and delta progradation.
