      The Lipovany and MuÄín paleobotanical localities contain important floral associations within the tuff horizons, which were used for determination of subtropical to tropical climatic conditions during Early Miocene. Based on the combination of results from plagioclase and biotite 40Ar/39Ar dating, the age of the tuff deposition was around 17.3 Ma. From the Lipovany locality, the plagioclase convergent age is 17.49 ± 0.54 Ma. Biotite convergent age is 17.28 ± 0.06 Ma. The MuÄín locality only provide a imprecise convergent age of 16.5 ± 1.4 Ma due to the small size of the plagioclase crystals analyzed. The results thus allowed to include the fossil subtropical flora of the studied localities to the late Ottnangian stage (upper part of the Burdigalian stage). Additionally, they also indicate late Ottnangian-Karpatian deposition age of the Salgótarján Formation
