Across the field sites we see examples of disaggregation to cataclastic DB sets and evidence of frequent reactivation by discrete faulting. Thin section analysis, cross-cutting relationships and well-defined time constraints of analysed brittle structures demonstrate that with increased burial depth, DB deformation mechanisms progressed from granular flow to cataclasis. The DB sets were classified into 10 deformation phases based on formerly published independent fault-slip analysis and structural mapping. Subsidence curves were constructed for each stratigraphic level involved in deformation and were used along with the intersection of deformation episodes to calculate the depth intervals of DB generations and subsequent structural elements. The DB formation depths obtained were transferred to the depth range of the related mechanisms. This combined methodology permits a more quantitative approach to determine the changes in the deformation mechanisms with depth. Our results show that granular flow (disaggregation bands) dominates down to 100-150 m as the earliest deformation structure, followed by weak then moderate cataclasis. The transition between weak and moderate cataclasis is at approximately 300 +/- 100 m for host rock rich in feldspar or fragile tuffitic components and from around 900 +/- 100 m in quartz-rich sediments. In addition, deformation by frictional sliding concentrates on discrete fault planes at the margin of cataclastic bands or on new fracture planes from similar to 500 +/- 100 m in volcanoclastic or feldspar rich host rocks, and 1000 +/- 100 m in quartz-rich host rocks. We suggest that burial-induced diagenetic processes is dependent on subsidence history, and partly in connection with regional fluid migration path, control the transition from moderate or advanced cataclasis to discrete fault slip. All these changes affect the pore structure and porosity that contribute to rheological changes, and hence change in deformation mechanism of coeval fracturing events.}, year = {2019}, eissn = {1873-4073}, pages = {1-16}, orcid-numbers = {Beke, Barbara/0000-0003-0797-1195; Petrik, Attila/0000-0001-6164-1758} } @article{MTMT:3244367, title = {A sequence stratigraphic investigation of a Miocene formation supported by coal seam quality parameters – Central Paratethys, N-Hungary}, url = {https://m2.mtmt.hu/api/publication/3244367}, author = {Püspöki, Zoltán and Hámorné, Vidó Mária and Pummer, T and Sári, Katalin and Lendvay, P and Selmeczi, Ildikó and Detzky, Gergely and Gúthy, Tibor and Kiss, János and Kovács, Zsolt and Prakfalvi, P and McIntosh, Richard William and Budayné Bódi, Erika and Báldi, Katalin and Markos, Gábor}, doi = {10.1016/j.coal.2017.05.016}, journal-iso = {INT J COAL GEOL}, journal = {INTERNATIONAL JOURNAL OF COAL GEOLOGY}, volume = {179}, unique-id = {3244367}, issn = {0166-5162}, abstract = {Abstract A stratigraphic investigation of the coal-bearing Miocene siliciclastic succession in structurally dissected basins of Northern Hungary was performed based on log correlations and is supported by coal petrology and sulphur data. The succession represents the Karpatian lower order global eustatic cycle of the Paratethys and was dissected into six higher order sedimentary sequences (sq-1 – sq-6). The coal-bearing strata in the Nógrád Basin (sq-1 – sq3) represent a lowstand systems tract (LST) prior to the Karpatian relative sea level rise. The transgressive systems tract (TST) starts with the ‘Oncophora Beds’ (sq-4) accumulated above a regional unconformity and containing coal beds in the Borsod Basin. The TST is superimposed by tectonically-forced higher order lowstand systems tracts (sq-5, sq-6) containing coal beds only in the relatively elevated East Borsod Basin. To support the sequence stratigraphic model, the average maceral and sulphur content of coal seams was also interpreted. The low sulphur (0.47%) content in sq.-1 reflects the lowstand environment determined by continental derived freshwater input. Transitional sulphur contents (0.66%–1.02%) in the late lowstand (sq-2 and sq.-3) indicate occasional saline invasions related to relative sea level rises. High (2.3%–2.6%) sulphur contents in the TST (sq-4) were caused by regular seawater inundations into the lagoon, while decreasing sulphur contents in sq-5 and sq-6 (2.28%–2.09%) reflect the increasing rate of freshwater income in association with the stepwise basinward shifts of the shoreline and the lagoonal facies. Within the Lower to Middle Miocene Salgótarján Lignite Formation, the analysis of coal seams contributed to the interpretation of relative sea level changes, and the sequence stratigraphic context facilitated both the interpretation of sulphur content in coals and the reliable correlation of coal seams.}, keywords = {sulfur; Miocene; Geochemistry; Isotopic composition; Sequence stratigraphy; INDICATOR; CENTRAL PARATETHYS; CENTRAL PARATETHYS; PEAT; Everglades; Coal petrology; DEPOSITIONAL-ENVIRONMENTS; Sulphur content; WESTERN CANADA; GATES FORMATION; OKEFENOKEE SWAMP}, year = {2017}, eissn = {1872-7840}, pages = {196-210}, orcid-numbers = {Kiss, János/0000-0001-8589-1364; Kovács, Zsolt/0000-0001-9394-7145; Báldi, Katalin/0000-0002-9154-2045} } @article{MTMT:3035752, title = {Cenozoic structural evolution of the southwestern Bükk Mts. and the southern part of the Darnó Deformation Belt (NE Hungary)}, url = {https://m2.mtmt.hu/api/publication/3035752}, author = {Petrik, Attila and Beke, Barbara and Fodor, László and Haranginé Lukács, Réka}, doi = {10.1515/geoca-2016-0005}, journal-iso = {GEOL CARPATH}, journal = {GEOLOGICA CARPATHICA}, volume = {67}, unique-id = {3035752}, issn = {1335-0552}, year = {2016}, eissn = {1336-8052}, pages = {83-104}, orcid-numbers = {Beke, Barbara/0000-0003-0797-1195; Haranginé Lukács, Réka/0000-0002-2338-4209} } @article{MTMT:2066910, title = {Stratigraphy and deformation history of the Jurassic coal bearing series in the Eastern Mecsek (Hungary)}, url = {https://m2.mtmt.hu/api/publication/2066910}, author = {Püspöki, Zoltán and Forgács, Z. and Kovács, Zs. and Kovács, E and Kablár-Soós, J. and Pusztafalvi, J. and Kovács, Zoltán and Demeter, Gábor and Buday, Tamás and Kozák, Miklós}, doi = {10.1016/j.coal.2012.07.009}, journal-iso = {INT J COAL GEOL}, journal = {INTERNATIONAL JOURNAL OF COAL GEOLOGY}, volume = {102}, unique-id = {2066910}, issn = {0166-5162}, year = {2012}, eissn = {1872-7840}, pages = {35-51}, orcid-numbers = {Kovács, Zs./0000-0001-9394-7145} } @article{MTMT:1354802, title = {Fiatal tektonikai jelenségek új észlelései a Nyugati-Mecsekben és környezetében}, url = {https://m2.mtmt.hu/api/publication/1354802}, author = {Konrád, Gyula and Sebe, Krisztina}, journal-iso = {FÖLDTANI KÖZLÖNY}, journal = {FÖLDTANI KÖZLÖNY}, volume = {140}, unique-id = {1354802}, issn = {0015-542X}, abstract = {Exposures of Neogene and Quaternary age were investigated along the main structural zones of the Western Mecsek Mts. (SW Hungary) in order to study post-Miocene tectonic activity, with an aim of supplementing studies on the longterm stability of the region. Field observations showed that young movements affected only the mountain fronts and the foreland. From the 24 studied exposures, those with impacts of tectonic activity were located along the major fault zones of the Western Mecsek Mts. and prove tectonic/seismic events occurring as late as the Late Pleistocene along the Mecsekalja Dislocation Zone and probably the Hetvehely–Magyarszék Fault. On the contrary, no impact of neotectonic activity was found within the Western Mecsek Anticline, indicating that this area behaved as a single solid block during post-Miocene movements. Since the Karpatian age, 5 tectonic phases could be distinguished. From these – somewhat opposing previous research – transtension seems typical for the Karpatian along the Hetvehely–Magyarszék Fault. The Early Pannonian transtensional stress field did not cease to exist at the beginning of the Late Pannonian. Tectonic inversion started only within the first half of the Late Pannonian and can be considered active up to present day in the major part of the area. A munka során a Nyugat-Mecsek fő szerkezeti vonalainak környezetében feltárt neogén és kvarter képződményeket vizsgáltuk fiatal (posztpannóniai) tektonikai aktivitás nyomai után kutatva, elsősorban a terület hosszú távú stabilitásának megítéléséhez. A terepi megfigyelések alapján a fiatal mozgások csak a hegységperemet és az előteret érintették. A vizsgált 24 feltárásból a fiatal tektonikával érintettek a Nyugat-Mecsek meghatározó szerkezeti vonalai mentén helyezkednek el, és még a késő-pleisztocénben is szerkezeti mozgásokat, illetve szeizmikus aktivitást bizonyítanak a Mecsekalja-öv és valószínűleg a Hetvehely–magyarszéki-törés mentén. Ezzel ellentétben a Nyugatmecseki- antiklinális területén belül neotektonikára utaló jeleket nem észleltünk, ez alapján a pannóniai–negyedidőszaki mozgások során a Nyugat-Mecsek egységes tömbként viselkedhetett. A kárpáti korszak óta öt tektonikai fázis volt elkülöníthető a területen. Ezek közül – a korábbi vizsgálati eredményekkel szemben – a kárpáti korszakra jellemzőnek tűnik a transztenzió a Hetvehely–magyarszéki-törés mentén. A kora-pannóniai transztenziós feszültségtér a Mecsekalja-öv mentén még a késő-pannóniai elején is fennállt. Az inverzió a késő-pannóniai első felében kezdődött és a terület legnagyobb részén máig aktívnak tekinthető.}, year = {2010}, eissn = {2559-902X}, pages = {135-161}, orcid-numbers = {Sebe, Krisztina/0000-0002-4647-2199} } @article{MTMT:1389120, title = {Truncated higher order sequences as responses to compressive intraplate tectonic events superimposed on eustatic sea-level rise.}, url = {https://m2.mtmt.hu/api/publication/1389120}, author = {Püspöki, Zoltán and Tóth-Makk, Á. and Kozák, Miklós and Dávid, Árpád and McIntosh, Richard William and Buday, Tamás and Demeter, Gábor and Kiss, János and Püspöki-Terebesi, M and Barta, K and Csordás, Cs and Kiss, J}, doi = {10.1016/j.sedgeo.2009.05.011}, journal-iso = {SEDIMENT GEOL}, journal = {SEDIMENTARY GEOLOGY}, volume = {219}, unique-id = {1389120}, issn = {0037-0738}, keywords = {ARCHITECTURE; STRATIGRAPHY; Pannonian Basin; Miocene; Sequence stratigraphy; COAL; DELTA PLAIN; DUNVEGAN FORMATION; STRANDED PARASEQUENCES; COAL-BEARING STRATA; ALBERTA FORELAND BASIN; CRETACEOUS CARDIUM FORMATION; WEDGE SYSTEMS TRACT; Tectonic tilting; Falling stage systems tract}, year = {2009}, eissn = {1879-0968}, pages = {208-236}, orcid-numbers = {Kiss, János/0000-0001-8589-1364; Kiss, J/0000-0001-8589-1364} } @article{MTMT:1247511, title = {U-Pb and Ar-40/Ar-39 dating of the Miocene fossil track site at Ipolytarnoc (Hungary) and its implications}, url = {https://m2.mtmt.hu/api/publication/1247511}, author = {Pálfy, József and Mundil, R and Renne, PR and Bernor, R L and Kordos, László and Gasparik, Mihály}, doi = {10.1016/j.epsl.2007.03.029}, journal-iso = {EARTH PLANET SC LETT}, journal = {EARTH AND PLANETARY SCIENCE LETTERS}, volume = {258}, unique-id = {1247511}, issn = {0012-821X}, keywords = {Proboscidean Datum; Central Paratethys regional stages; 40Ar/39Ar dating; Miocene, U–Pb dating}, year = {2007}, eissn = {1385-013X}, pages = {160-174}, orcid-numbers = {Pálfy, József/0000-0001-9686-1849} } @article{MTMT:1369020, title = {Post-Conference Excursion: Tectonics, sedimentation and magmatism along the Darnó Zone}, url = {https://m2.mtmt.hu/api/publication/1369020}, author = {Fodor, László and Radócz, Gy and Sztanó, Orsolya and Koroknai, B and Csontos, L and Harangi, Szabolcs}, journal-iso = {GEOLINES}, journal = {GEOLINES}, volume = {19}, unique-id = {1369020}, issn = {1210-9606}, year = {2005}, pages = {142-162}, orcid-numbers = {Sztanó, Orsolya/0000-0003-0786-3653; Harangi, Szabolcs/0000-0003-2372-4581} } @article{MTMT:1763186, title = {Early Miocene basin evolution in northern Hungary: Tectonics and eustasy}, url = {https://m2.mtmt.hu/api/publication/1763186}, author = {Sztanó, Orsolya and Tari, Gábor}, doi = {10.1016/0040-1951(93)90134-6}, journal-iso = {TECTONOPHYSICS}, journal = {TECTONOPHYSICS}, volume = {226}, unique-id = {1763186}, issn = {0040-1951}, abstract = {It is presumed that the Oligocene-early Miocene basin evolution in northern Hungary was primarily driven by compressional tectonics, producing a major second-order transgressive-regressive facies cycle. The early Miocene basin evolution is best understood in terms of ''molasse'' sedimentation in an overfilled flexural basin. During this time the gradual cessation of thrusting in the adjacent West Carpathian thrust-fold belt resulted in its uplift and subaerial exposure. Significant amounts of sediment were delivered to the flexural basin filling it up to sea level. During the late-stage uplift of the flexural basin a shallow-marine depositional environment developed, as a result of isostatic rebound, and signals of third-order eustatic sea-level changes can be revealed. Sedimentological studies of outcrops of the Lower Miocene succession proved marked changes in facies. Along the gently dipping distal (southeastern) flank of the basin a sudden inception of shallow-marine coarse clastics on top of siltstones, deposited in significantly deeper water, may have been the result of a third-order eustatic sea-level fall shortly before the Burdigalian (at the boundary of the NN1/NN2 nannofossil zones). During the resulting lowstand, various tide-dominated facies aggraded, which were subsequently flooded by the ''Burdigalian sea-level rise''. The highstand is represented by upwards shallowing progradational units due to accelerating sedimentation and/or tectonic uplift. The typically elongated and narrow flexural basin, characterized by small water depth, had dimensions which were particularly suitable for the amplification of tidal motions. This resulted in the deposition of tide-influenced sandy sediments. In contrast to examples where the evolution of a strong tidal influence is related to transgressions, here such conditions developed following a drop of sea level.}, keywords = {MODEL; SWITZERLAND; molasse; TIDE}, year = {1993}, eissn = {1879-3266}, pages = {485-502}, orcid-numbers = {Sztanó, Orsolya/0000-0003-0786-3653} }
