Opis:
Pseudotachylite is produced both during tectonic activity as well as by impact of a large celestial body. Special conditions of its petrogenesis and characteristics of host rocks determine the variability of pseudotachylite. This variability creates difficulties in its identification and classification as well as in determining the ways of its formation. The variable classifications require comparisons with other tectonic and impact rocks. The few non-obligatory characteristics of matrix and clasts differentiate tectonic and impact pseudotachylite. Both tectonic and impact activities create the final form of astrobleme. The rock was characterized on the basis of materials from Vredefort, Ries, Siljan, Dellen and some glacial erratics from Lower Silesia, SW Poland.

Opis:
The Mid-Polish Trough formed the axial part of the Polish Basin belonging to a system of the Permian-Mesozoic epicontinental basins of Western and Central Europe. It was filled by several kilometres of siliciclastics and carbonates, including thick Zechstein (approximately Upper Permian) evaporites. TheMid-Polish Trough was inverted in the Late Cretaceous-Paleocene times, when it was strongly uplifted and eroded. The presence of thick salt significantly influenced Triassic evolution of the central (Kuiavian) part of theMid-Polish Trough where the Kłodawa salt structure is located. Analysis of seismic data calibrated by several deep wells point to three main stages of the Triassic evolution of this structure. During Early andMiddle Triassic Kłodawa salt pillow grew above the basement extensional fault zone, during early Late Triassic (approx. time of deposition of the Lower Gypsum Beds) Kłodawa salt structure reached diapiric stage and salt eventually extruded on to the basin floor. Last stage was characterised by rather uniform sedimentation and lack ofmajor saltmovements. Wojszyce salt pillow located north-east of the Kłodawa salt structure grew until the Late Triassic (approx. time of deposition of the Upper Gypsum Beds) when basement fault zone located below it was probably inverted. This inversion triggered formation of the salt-cored Wojszyce Anticline and was followed by localised erosion and rather uniform Norian–Rhaetian (Lower Kłodawa Beds) sedimentation above the anticline. Local tectonic activity below the anticline might have additionally enhanced growth of the Kłodawa salt diapir. The presented tectono-sedimentary model of the relationship between basement and salt tectonics and their influence on the Triassic depositional systems is compatible with results of analogue modelling of linked basement-salt tectonics, and with a model based on mesostructural studies completed for the Kłodawa salt mine.

Opis:
The northern part of the Carpathians covers the north-eastern area of the Western and north-western of the Eastern Carpathians. The basement of the Carpathians in this zone is of a transitional nature and is relatively poorly explored, which results from its deep burial, in particular under the so-called Outer Carpathians. The interpretation of the tectonics and geodynamics of the basement depends to a large extent on the analysis of large scale geophysical data. In this area, regional seismic surveys were carried out mainly using the so-called deep refraction and numerous geophysical works using gravity, magnetic, geomagnetic and magnetotelluric methods. The subject of the presented work is a review of the regional image of electromagnetic and gravity studies carried out in this area, with particular emphasis on the territory of Poland, within which the authors carried out numerous research works. Electromagnetic research allows for the construction of a regional model of basement resistivity distributions and the determination of general outlines of its geometry as well as the formulation or testing of the concept of its geodynamical interpretations. An auxiliary role in this aspect is played by gravity data allowing to recognize the density distribution of the basement and constituting a set of additional data for integrated interpretation. The area outside the territory of Poland was presented on the basis of literature data, creating an extensive regional background for the results of research related with the participation of the authors in Poland. Within the Polish Carpathians, there is a structural reconstruction of the Carpathian overthrust and its basement, as well as a clear change in the nature of geophysical fields, e.g. the system of gravity field anomalies. Due to the deep burial of the Carpathian overthrust in this area and the complex structure of the orogen, which hinder effective drilling penetration, its fragmentary and uncertain recognition is based mainly on geophysical surface studies. The complex structure of the orogen reduces the effectiveness of the use of the seismic reflection method, the participation of which is limited in practice to the recognition of the basement in the marginal zone of the Carpathian overthrust. In the remaining area, alternative methods of surface geophysics are used, i.e. the magnetotelluric and gravity method. An important role in recognizing the basement of the Eastern part of the Polish Carpathians was played by magnetotelluric soundings that cover the above mentioned area with a relatively dense network of several generations of measurement points. The results of the interpretation of the MT soundings were used to construct a resistivity model, which was verified by new results of regional processing of seismic data and magnetotelluric and gravity modelling. The visualization of resistivity distributions was presented through maps interpreted at selected depth levels and in the resistivity cross-sections form. Resistivity distributions are the basis for interpreting tectonic zones marked as resistivity contrasts. Forward modelling and inversion of gravity data were used to verify resistivity structural models.

Late Miocene
Opis:
The Northern Sicilian-Maghrebian Chain courses W-E from the Trapani Mts to the Peloritani Mts and is composed by a set of tectonic units deriving from the Miocene-Pleistocene deformation of the Northern African Continental Margin. Inside it three main geotectonic elements ("external", Sicilide and "Austroalpine") are present and outcrop juxtaposed with a W-E trend. The external element composes the more western Trapani, Palermo and Western Madonie Mts, the Sicilide composes the Eastern Madonie and Nebrodi Mts, while the "Austroalpine" composes the more eastern Peloritani Mts. The orogen shows a culmination in the Trapani Mts and a depression in the Peloritani Mts. The main plicative stages are relatable to late Oligocene-early Miocene from the more internal sectors, while the deformation of the more external sectors starts from early-middle Miocene. The Sicilian chain body is re-involved in tectonism since late Tortonian, which persists until the recent time. During this interval, the deformation of the Sicilian Chain continued by activation of fault systems with different displacements. In the present paper, an important extensional tectonic stage is recognised, starting from the Tortonian; it is supported by structural data and shows through several geological sections across the northern sectors of the Sicilian orogen. This deformation is of exceeded wedge critical taper values, controls the early stages of the Tyrrhenian Basin opening, and is represented by low-angle fault system, producing tectonic omissions in the stratigraphic sequence. The detachment fault system is subsequently displaced by a complicated grid of Plio-Pleistocene net- and strike-slip fault system that controls the genesis of tectonic depressions in the northern off-shore areas of the Sicilian Chain. This neotectonic system may be reconnect to a W-E trending simple shear system, which controls the more recent Tyrrhenian Basin development.

Roztocze
Opis:
The relatively undeforrned South-West escarpment zone (SWEZ) of Roztocze, SE Poland, is marginal to the East European Platform, which is covered by a thick succession of Palaeozoic and Mesozoic rocks. Cainozoic sediments, previously much more widely distributed and largely destroyed by erosion, still fill some valleys and also crop out in the hills of the inner and outer escarpments. The escarpment zone comprises several morphological elements: an outer hill zone, inner inselbergs and a median depression zone of tectonic origin. Transverse to the escarpment, these elements are compartmentalised by transverse valleys, many of which are fault-controlled. Morphometric and geomorphological studies show that the SWEZ of Roztocze was repeatedly tectonically activated. Neotectonic redevelopment has resulted from controls in the underlying basement. Hence there are many young faults, a large number of open fault-fissures and a complex system of joints, all of which have influenced landform development in this area to a considerable degree. The main scarps have been developed along the longitudinal fault zones and, along the transverse fault zones, breach valleys. Joint systems have controlled the development of secondary relief forms. The close association of relief and various elements of the geological structure in the SWEZ of Roztocze mean that cartographic methods can reliably be employed in studies of the landforms in this area.

Opis:
Based on reflection seismic data, a regional tectonicmodel was constructed for the sub-Zechstein basement of the Pomeranian (NW) segment of theMid-Polish Trough (MPT). This model is based on the concept that the thick Zechstein salts acted on a basin-wide scale as a mechanical decoupling layer during the Mesozoic evolution of the MPT. Due to this regional decoupling effect, Mesozoic extensional faulting was mostly restricted to the sub-Zechstein salt basement whilst normal faulting played a subordinate role in the Mesozoic syn-extensional sedimentary series characterized by gradual lateral thickness changes. Locally, normal faulting affecting Mesozoic series triggered the development of salt diapirs. Mechanical decoupling ofMesozoic series fromtheir pre-Zechstein substratum played also an important role during the Late Cretaceous-Paleogene inversion of the Mid-Polish Trough. Taking into account: 1— the location of Mesozoic thickness gradients, 2—the structural configuration of the sub-Zechstein basement, and 3—the location of salt structures, a tectonic map was constructed showing the inferred sub-salt fault zones that were active during the subsidence and inversion of the Pomeranian part of the MPT. A high degree of correlation was achieved between the seismically mapped regional sub-salt structural patterns and magnetic and gravity features, as well as the main inversion structures. Moreover, a very good correlation was established between the inferred basement fault zones and the gross thickness patterns of the Triassic-Jurassic successions. The NE boundary of theMPT was generally controlled by the SW margin of the East European Craton, whilst its SW boundary coincides with a system of fault zones most probably inherited from earlier tectonic phases. Contrary to previous hypotheses, there is no evidence for important strike-slip faulting transverse to the main axis of the Pomeranian segment of the MPT.

The area of the City of Zagreb, which is the boundary zone of Eastern Alps, Dinnarides and Pannonian Basin is incIuded as well. It is shown here that the evidence for fractures of Eastern Adriatic differs from the previous hypotheses. This concIusion is derived from the results of various geodetic measurements: satellite positioning (GPS), astro-geodetic measurements of detlections of the vertical. These results are combined with geologic measurements and results of seismic activity studies in order to give more detailed and more accurate picture of the current situation in the tectonically very active region of Dinnarides. Several GPS-campaigns performed in the City of Zagreb area are examined as well. Due to the proximity of Croatian capitol, special attention has been paid to the effects of possible hazard on construction code.

Abundant detrital albite grains suggest volcanism during sedimentation. Pebbles in conglomerate interbeds are polymict and include rock fragments showing greenschist facies regional metamorphism in the source area. The Precambrian surface in the marginal part of the Carpathians lies at 2000-5000 m b.s.l., whereas farther south, around Kuźmina it reaches 7000 m. Still farther south (Krosno-Sanok-Baligród) geophysical evidence suggests it lies at about 17-20 km depth.

Opis:
Western Sicily represents a fragment of the Apenninic-Maghrebian Chain, largely built during the Miocene and formed by a set of tectonic units with southern vergence of folds and ramp-flat style of thrust surfaces. The thrust tectonics-related structures are displaced by a high-angle fault system, which bounds the main Mesozoic "carbonatic massifs" and generally interpreted as a neotectonic dip-slip extensional tectonics-related faults. The present paper, with the support of mesostructural analysis, presents an important Plio-Pleistocene strike-slip tectonics, represented by high-angle net- and strike-slip fault system. Different scale flower structures and associated fold systems, which cut the Miocene tectonic units, characterise the areas along the main transcurrent fault zones. Strike-slip neotectonics is mostly represented by right-lateral NW-SE/W-E and left-lateral N-S/NE-SW transcurrent faults, which may represent a W-E trending deep-seated Riedel system connected to the Tyrrhenian spreading. The NW-SE first order synthetic structures appear to control the opening of several rhomboidal tectonic depressions located in north-western Sicily and its offshore, and are counteracted by W-E trending transpressional structures located in the central Sicily mainland. An attempt at semi-quantitative restoration shows the neotectonic evolution of north-western Sicily during the Pliocene and Pleistocene, characterised by the progressive activation towards the east of en-échelon strike-slip fault strand, in an overall horsetail splay geometry, which produced releasing bends in off-shore and restraining bends in the mainland.

Opis:
The topmost part of the Oxfordian limestones, building the Zakrzówek Horst in Kraków, is featured by a network of minute fissures, filled with Upper Cretaceous limestones. Fissures are dominantly subhorizontal, anastomosing and polygonal in plane. They are filled with white limestones representing mostly foraminiferal- calcisphere wackestones, with subordinate amount of quartz pebbles and fragments of stromatolite coming from the latest Turonian-?Early Coniacian conglomerate overlying Oxfordian basement. The fissures are seismically- induced injection dykes. In contrast to gravitationally-filled neptunian dykes the recognised injection dykes were filled by overpressured soft sediments. Foraminifera within some dykes are abundant, and dominated by planktonic forms, which indicate the Early/Late Campanian age (Globotruncana ventricosa and Globotruncanita calcarata zones) of the filling, and hence date also the synsedimentary tectonics. Abundant and diversified keeled globo- truncanids in the Campanian of the Kraków region are recognised for the first time. Other important findings at the studied section include karstic cavities featuring the surface of the Oxfordian bedrock filled with conglomerates of the latest Turonian-?Early Coniacian age based on foraminifera and nannoplankton, and lack of Santonian deposits, which elsewhere are common in the Upper Cretaceous sequences in the Kraków region. The discovered Campanian dykes provide new evidence for the Late Cretaceous tectonic activity on the Kraków Swell related to the Subhercynian tectonism, which resulted among others in stratigraphic hiatuses and unconformities characte- ristic of the Turonian-Santonian interval of this area.

The modern theory of plate tectonics has been the basis of works of several generations of geologists and geophysicists. One of them was Alfred Wegener and his theory of continental drift. The imperfection of the theory (lack of any explanation for the mechanism of continents movement) was the driving force for further studies. The most important ones were the detailed recognition of the ocean floor, and the discovery of the rift and subduction zones.

Opis:
Amalgamation of tectonic plates of Southeast Asia occurred in northwestern Vietnam. Six groups of magmatic rocks are related to the tectonic events. The first group corresponds to the major episodes of crustal formation in the South China block, or is linked with the formation of Gondwana. The second group includes granitoids in connection with the collision and formation of the Caledonian-Hercynian folding event. The third group contains Upper Permian ophiolites, as well as the Permian extrusives, formed in intraplate setting, related to back-arcs spreading. The fourth group is related to Triassic Indosinian orogeny, the fifth group comprises Jurassic-Cretaceous intraplate granitoids. Finally, during Cenozoic times, magmatic rocks were represented by alkaline granitoids - the effect of strike-slip faulting related to the collision of India and Eurasia plates.
