AB - 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. LA - Hungarian DB - MTMT ER - TY - JOUR AU - M.

Extensional formation of the basin system commenced in the early Miocene, whereas its structural reactivation, in the form of gradual basin inversion, has been taking place since Pliocene to recent times. Reconstructed compression and associated horizontal contraction are mainly governed by the convergence between Adria and its buffer, the Alpine belt of orogens. The resulting contemporaneous stress field exhibits important lateral variation resulting in a complex pattern of ongoing tectonic activity. In the Friuli zone of the Southern Alps, where thrust faulting prevails, compression is orthogonal to the strike of the mountain belt. More to the southeast, intense contraction is combined with active strike-slip faulting constituting the dextral Dinaric transpressional corridor. Stresses are transferred far from Adria into the Pannonian basin, and the dominant style of deformation gradually changes from pure contraction through transpression to strike-slip faulting. The importance of late-stage inversion in the Pannonian basin is interpreted in a more general context of structural reactivation of backarc basins where the sources of compression driving basin inversion are also identified and discussed. The state of recent stress and deformation in the Pannonian basin, particularly in its western and southern part, is governed by the complex interaction of plate boundary and intra-plate forces. The counterclockwise rotation and north-northeast-directed indentation of the Adriatic microplate appears to be of key importance as the dominant source of compression ("Adria-push"). Intra-plate stress sources, such as buoyancy forces associated with an elevated topography, and crustal as well as lithospheric inhomogeneities can also play essential, yet rather local role.

There is a high dispersion of cumulative-length exponents, box dimensions and fracture densities. However, the fractal analysis supports the fractal nature of fracture arrays. Our data indicate the existence of an upper limit for the density parameters, as similarly reported by other authors. We prove that box dimension is in inverse relation with fracture concentration and in direct relation with fracture density. These relations are also observed in our data and additionally there is an upper limit for the box dimensions. We interpret the dispersion in our results as more fundamental than methodological problems. It represents a truncation in the complete evolution of the fracture systems because in natural cases strain initiates overprinting of previous fracture arrays. Considering that larger fractures accommodate strain more efficiently than small fractures, the generation of small fractures is inhibited in the presence of pre-existing larger fractures. Maximum values of fracture density prevent accommodating an excess of strain in a single or restricted range of scales; we claim this condition produces migration of fracturing to larger scales originating fracture scaling.

This combination of data helped to reconstruct the possible activity of individual fault zones. At least four ENE-WSW striking zones-the Northern Imbricates, the South Mecsek zone, the Gorcsony-Mariakemend ridge and the Villany Mountains-were confirmed as regional long-lived transpressive zones with very complicated internal deformation, frequently with oppositely dipping thrust faults. Tertiary structural history began with a roughly N-S-directed shortening in the South Mecsek zone. It was followed by a NE-SW-directed transpression activating practically all important wrench zones together with perpendicular transfer faults. Basins were created along some of these deformation zones, but were also affected by major tilts due to inversion. After a relatively quiescent period in the Middle Miocene, the Late Sarmatian inversion followed. Shortly after, this event was relayed by a NE-SW-directed extension-transtension. An important inversion period characterised by NW-SE compression occurred in Late Pannonian (Messinian), when all the former wrench zones were reactivated as right-lateral shear. This event is responsible for the present topography of the region. (C) 2002 Elsevier Science B.V. All rights reserved.
