The Lipovany and Mu?ín 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 combination results from plagioclase biotite 40Ar/39Ar dating, age deposition is around 17.3Ma. For locality, single-grain convergent ages 17.49±0.54Ma 17.28±0.06Ma, obtain...

A new and precisely defined chronometric subdivision of the Badenian (Middle Miocene, regional stage of Central Paratethys) is proposed. This uses global events, mainly geomagnetic polarity reversals as correlated chronometric boundaries, supported by climatic and sea-level changes in addition to isotope events and biostratigraphic data. The Karpatian/ Badenian boundary lies at 16.303 Ma, at th...

Thermopsideae has 45 species and exhibits a series of interesting biogeographical distribution patterns, such as Madrean-Tethyan disjunction and East Asia-North America disjunction, with a center of endemism in the Qinghai-Xizang Plateau (QTP) and Central Asia. Phylogenetic analysis in this paper employed maximum likelihood using ITS, rps16, psbA-trnH, and trnL-F sequence data; biogeographical ...

Magyarországon a kronosztratigráfia tudománya az 1980-as és 1990-es évek során szembesült azzal jelenséggel, hogy klinotémákkal kitöltött medencékben, mint amilyen Pannon-tó medre is volt, Steno települési törvényei nem, vagy csak nagyon korlátozott értelemben érvényesek. A pannóniai emeletet nem eredetileg vízszintes, hanem dőlő, több száz méter vertikális kiterjedésű, klinoform geometriájú id...
