Correlation of the Paleogene and Neogene deposits from Northern Transylvania

The study was concentrated on the Paleogene and Neogene deposits from the border of the Gilău Mountains, east Meseş Mountains, south of Ţicău and Preluca Massifs, the Transcarpathian flysh, as well as those from of south Rodna Mountains. The formations are made up of continental (including fluvial and lacustrine) and normal marine deposits. Based on the nannoplancton data, these were compared to those of the Transcarpathian flysch. In the case of the marine deposits, 5 sedimentation cycles were separated. The last cycle belongs to the Badenian, marked by a general transgression, represented by conglomerates and marls in the base allowed by Dej Tuff and salt deposits. Starting with the Badenian, the Transylvanian Depression evolved as a unitary basin
