“…The lack of crustal thickening and formation of mountains in this deformed zone can be attributed to orogen-parallel extension, perhaps facilitated by increased heat flux caused by large amounts of Miocene syn-tectonic volcanics (Csontos & Nagymarosy 1998;Kovács et al 2007).…”

Abstract:Recently shot 3D seismic data allowed for a detailed interpretation, aimed at the tectonic evolution of the central part of the Mid-Hungarian Shear Zone (MHZ). The MHZ acted as a NW vergent fold and thrust belt in the Late Oligocene. The intensity of shortening increased westwards, causing clockwise rotation of the western regions, relatively to the mildly deformed eastern areas. Blind thrusting and related folding in the MHZ continued in the Early Miocene. Thrusting and gentle folding in the MHZ partly continued in the earliest Pannonian, and was followed by sinistral movements in the whole MHZ, with maximal displacement along the Tóalmás zone. Late Pannonian inversion activated thrusts and generated transpressional movements along the Tóalmás zone.

“…Reviewing and extending tectonic studies based on 2D industrial seismic data (Csontos & Nagymarosy 1998), the current study aims at the tectonic interpretation of three recently shot overlapping 3D seismic cubes of MOL PLC. (1500 km 2 ) in the central part of the MHZ, southeast of Budapest (Fig.…”

1 Fac ulty of Min ing, Ge ol ogy and Pe tro leum En gi neer ing, Uni ver sity of Zagreb, Pierottijeva 6, Zagreb, Croatia Mt. Medvednica is an inselberg in NW Croatia, which lies at the in ter sec tion be tween the Southeastern Alps, Northwestern Dinarides and Tisza Mega-Unit of the Pannonian Ba sin. Due to the Pliocene-Quaternary N-S di rected short en ing, Mt. Medvednica ex pe ri enced 1500-2000 m of dif fer en tial up lift and now ex poses pre-Neo gene and Neo gene tec tonic and stratigraphic units that are sur rounded by Pliocene-Quaternary sed i ments. This pa per eval u ates a set of quan ti ta tive morphometry meth ods used to iden tify tec toni cally ac tive ar eas within this re gion characterized by low-rate ac tive fold ing and fault ing dur ing the Pliocene-Quaternary. Our anal y sis em ployed ex trac tion of hypsometric curves, cal cu la tion of a hypsometric in te gral, asym me try fac tor, and sta tis ti cal pa ram e ters of lon gi tu di nal stream pro files along 36 drain age bas ins de lin eated from a 25 m res o lu tion DEM of Mt. Medvednica area. De spite lithological het er o ge ne ity of the study area, the morphometric pa ram e ters we ob tain are good in di ca tors for dis crim i nat ing tec toni cally ac tive from in ac tive ar eas. We in terpret that the most tec toni cally ac tive ar eas are lo cated at the SW cor ner and in the cen tral part of Mt. Medvednica, where they are likely re lated to the North Medvednica Bound ary Fault, and to the Kašina Fault, re spec tively. The lat ter di vides the range into dis tinct NE and SW mor pho log i cal and struc tural ar eas.

“…The KIHA-NE Field is situated south of the Mid-Hungarian tectonic zone that separates the Tisza Unit from the Alcapa Unit (Csontos and Nagymarosi 1998). According to recent interpretations the study area is located rather close to the assumed front of the Codru Nappe, which was formed as a result of Cretaceous tectonic activity.…”

The Kiskunhalas-NE (KIHA-NE) fractured hydrocarbon reservoir is part of the structurally rather complex crystalline basement of the Great Hungarian Plain. In the course of petrologic and thermometric examinations various rock types of the investigated area have been classified and characterized. There are four basic lithological units in the area. In the lowest structural position orthogneiss is common, which according to its petrographic features is assumed to be identical to the orthogneiss body of the adjacent Jánoshalma (JH) basement high (metamorphic peak temperature T < 580 °C according to Zachar and M. Tóth 2004). The next rock unit upward is the highly mylonitized variety of the orthogneiss with textural features suggesting deformation in an extensional stress regime. In the higher section of the mylonite zone graphitic gneiss mylonite is characteristic, with a peak metamorphic T of 410±45 °C. The lithology in the shallowest position of the area is a graphitic carbonate phyllite, with a T of 375 ± 15 °C. Estimation of the deformation temperature for both mylonitic rocks results in approximately T def~ 455 °C. All data together suggest that between the top (graphitic carbonate phyllite) and the bottom (orthogneiss) of the ideal rock column there is about 200°C peak metamorphic temperature deviation. The two extreme metamorphic blocks probably became juxtaposed along an extensional fault zone in the basement at approximately 15 km depth.
