“…The Sr-age of Darnó Fm. is taken from Less et al (2015) (Ádám 2006;Püspöki et al 2009). The relationship between the volcanic rocks and sedimentary formations (Pelikán 2005), and the new preliminary U-Pb ages (Lukács et al 2014a,b;Lukács et al 2015) indicate that the coalbearing sequence is younger, and could involve only the upper Ottnangian (ca.…”

Extensive structural field observations and seismic interpretation allowed us to delineate 7 deformation phases in the study area for the Cenozoic period. Phase D1 indicates NW-SE compression and perpendicular extension in the Late Oligocene-early Eggenburgian and it was responsible for the development of a wedge-shaped Paleogene sequence in front of north-westward propagating blind reverse faults. D2 is represented by E-W compression and perpendicular extension in the middle Eggenburgian-early Ottnangian. The D1 and D2 phases resulted in the erosion of Paleogene suites on elevated highs. Phase D2 was followed by a counterclockwise rotation, described in earlier publications. When considering the age of sediments deformed by the syn-sedimentary D3 deformation and preliminary geochronological ages of deformed volcanites the time of the first CCW rotation can be shifted slightly younger (~17-16.5 Ma) than previously thought (18.5-17.5 Ma). Another consequence of our new timing is that the extrusional tectonics of the ALCAPA unit, the D2 local phase, could also terminate somewhat later by 1 Myr. D4 shows NE-SW extension in the late Karpatian-Early Badenian creating NW-SE trending normal faults which connected the major NNE-SSW trending sinistral faults. The D5 and D6 phases are late syn-rift deformations indicating E-W extension and NW-SE extension, respectively. D5 indicates syn-sedimentary deformation in the Middle Badenian-early Sarmatian and caused the synsedimentary thickening of mid-Miocene suites along NNE-SSW trending transtensional faults. D5 postdates the second CCW rotation which can be bracketed between ~16-15 Ma. This timing is somewhat older than previously considered and is based on new geochronological dates of pyroclastite rocks which were not deformed by this phase. D6 was responsible for further deepening of half-grabens during the Sarmatian. D7 is post-tilt NNW-SSE extension and induced the deposition of the 700 m thick Pannonian wedge between 11.6-8.92 Ma in the southern part of the study area.

Merely of 454 m maximum elevation, the geologically and geomorphologically diverse and still dynamic Uppony Mountains is relatively rich in geomorphic features (caves, pseudocaverns, gorges, horsts, scarps, landslides, karren, natural outcrops) created by diverse processes (valley incision, derasion, mass movements, karst formation, periglacial, pedimentation). This small mountainous area with its intricate geological structure is ideal either for field investigations in order to obtain broader knowledge on the evolution of NorthHungary or to study both convergent and divergent evolution of forms generated on different rocks. Using a comparative approach, with an outlook to its environs, the quantification and numeric analysis of morphometric and lithological features combined with the traditional descriptive geomorphic approach promotes a better understanding of the area so important in the paleoenvironmental, paleogeographical reconstruction of North-Hungary. IntroductionThe Uppony Mountains of 240 km 2 area are located in northeastern Hungary, in the Bükk Mountains northern foreland. It is mainly composed of slightly metamorphosed Paleozoic siliciclastic rocks and limestones with distant Alpine contacts, surrounded by semiconsolidated Neogene marine sediments. Its uniqueness is primarily due to the particular geology: both karstic and non-soluble, as well as highly diagenized and semi-consolidated sediments occur in the area. This geology induced diverse geomorphic processes (valley incision, derasion, mass movements, karst formation, periglacial), which created a variety of landforms (small caves, non-karstic pseudo-caverns, scarps, bedrock outcrops, rock crags). The folded-imbricate structure, with the south-easterly dipping reverse faults of the PaleoMesozoic massif (Pelikán 2005), resulted in scarps of different resistance to weathering and formation of fascinating cliffs. Owing to the imbricate structure, the buried Paleozoic rocks of the neighbouring Bükk Mountains to the south (composed of Mesozoic limestone-nappes with southern vergence) can be studied here exposed on the surface. Along the abundant fault lines tectonically preformed, asymmetrically incised valleys and gorges were formed exposing the second oldest (Late Ordovician-Permian) rock assemblage of the uplifted continental floor in Hungary and thus creating an opportunity for paleoenvironmental reconstruction. The preserved Neogene cover and the traceable erosion surfaces indicate well-dated transgression and exhumation periods. Thus, the post-sedimentary (orogenic) geomorphic history of the mountains can also be well detected. The origin of landforms, the effects of selective denudation on hard and loose rocks, slope evolution and downwearing processes can be studied within a few kilometres' distance ( Fig. 20.1). Geological and Geographical SettingsThe Uppony Mountains are bordered by the Tardona Hills (E), the Bükk Mountains (S), the Ózd-Egercsehi Basin (W), the Vajdavár Hills (NW) and the tectonically preformed valley of the Saj...
