abstract = {We aimed to determine variations in stress regimes during the youngest Variscan deformations in the northern part of the Bohemian Massif. For this purpose, we calculated the orientation of the principal stress and strain axes for kink folds observed in the metamorphic envelope of the Karkonosze Granite, using two methods: 1) the traditional method, incorporating structural diagrams (for conjugate kink folds only), and 2) butterfly diagram analysis. The use of both methods enabled us to determine the stress regime, based not only on conjugate but also on monoclinal kink bands. The obtained results prove that butterfly diagram analysis, when applied to monoclinal kink folds, yields reliable results, especially when calibrated using the internal friction angle (Ф) calculated for the conjugate structures. We identified two generations of kink folds: 1) an older one, developed under sublatitudinal shortening and most probably related to the Early Carboniferous terminal stages of the northwest-directed thrusting of the metamorphic units, and 2) a younger one; produced by north-south Variscan Carboniferous compression, and the emplacement and subsequent doming of the Karkonosze Granite. This is the first study on brittle-ductile structures observed commonly in the metamorphic units of the Bohemian Massif, showing their relation to the granitoid intrusion and complementing the tectonic models that usually omit kink folds. © 2019 Académie des sciences},

We aimed to determine variations in stress regimes during the youngest Variscan deformations in the northern part of the Bohemian Massif. For this purpose, we calculated the orientation of the principal stress and strain axes for kink folds observed in the metamorphic envelope of the Karkonosze Granite, using two methods: 1) the traditional method, incorporating structural diagrams (for conjugate kink folds only), and 2) butterfly diagram analysis. The use of both methods enabled us to determine the stress regime, based not only on conjugate but also on monoclinal kink bands. The obtained results prove that butterfly diagram analysis, when applied to monoclinal kink folds, yields reliable results, especially when calibrated using the internal friction angle (Ф) calculated for the conjugate structures. We identified two generations of kink folds: 1) an older one, developed under sublatitudinal shortening and most probably related to the Early Carboniferous terminal stages of the northwest-directed thrusting of the metamorphic units, and 2) a younger one; produced by north-south Variscan Carboniferous compression, and the emplacement and subsequent doming of the Karkonosze Granite. This is the first study on brittle-ductile structures observed commonly in the metamorphic units of the Bohemian Massif, showing their relation to the granitoid intrusion and complementing the tectonic models that usually omit kink folds. © 2019 Académie des sciences

abstract = {A spectacular epigenetic silicification was encountered in the Oxfordian bedded limestones exposed in the Sokole Hills situated in the Krakow-Częstochowa Upland. The main epigenetic mineral is microcrystalline quartz accompanied by minor goethite, hematite, barite, galena and sphalerite.

The epigenetic mineralization of the bedded limestones was probably a two-stage process. During the first, Early Cretaceous stage, silicified limestones formed at the erosional surface of a denuded carbonate complex. Such silicification greatly limited the progress of the first karstification phase of the Upper Jurassic carbonates initiated in the Hauterivian. The sources of silica accumulated in the limestones were descending solutions enriched in silica derived from the weathering zone. This silicification affected the topmost part of the Upper Jurassic massive limestones and the deeper portions of the bedded limestones along the fracture systems and stylolites. Early Cretaceous tectonic activity generated new dislocations and re-opened the existing faults, which were subsequently filled with permeable Albian quartz sands. These openings became the migration pathways for ascending, warm, relict, sulphide-carrying hydrothermal solutions at the second formation stage of the epigenetic mineralization. The newly supplied silica from the Albian sands precipitated on the silicified limestones and, as concentric rims, on brecciated, early diagenetic cherts. The second-stage mineralization proceeded under phreatic conditions, presumably close to a fluctuating mixing zone of ascending, warm hydrothermal solutions and descending cold groundwaters. The brecciated cherts acting as silica crystallization nuclei indicate that the last mineralization stage probably followed the final phase of Cenozoic faulting. © 2015 Acta Geologica Polonica.},

abstract = {New geological, geochemical and U-Pb SHRIMP zirconage data brought more information about basement units in subsurface of Southern Poland and SE Romania, which allows to revise and refine some earlier models in the framework of the break-up of the Rodinia/Pannotia supercontinent. In the Brno Block, Moravia, and in the Upper Silesia Block, three different terranes formed the composite Brunovistulia Terrane. The Thaya Terrane (low eNd (T)) of Gondwana (Amazonia) descent collided obliquely at 640-620 Ma with the Slavkov Terrane (moderate eNd (T)) composed of amphibolitefacies metasediments and arc-related, mostly unfoliated granitoids which intruded at 580-560 Ma. At that time, back-arc rifting separated the couple Thaya-Slavkov (inherited zircons: 1.01-1.2; 1.4-1.5; 1.65-1.8 Ga) that drifted away from Gondwana until collision around 560-550 Ma with the Rzeszotary Terrane, the Palaeoproterozoic (2.7-2.0 Ga) crustal sliver deriVěd from Amazonia or West Africa. Atleast these three units composed Brunovistulia, which occurred at low latitudes in proximity to Baltica as shown by palaeomagnetic and palaeobiogeographic data. Then Brunovistulia was accreted to the thinned passive margin of Baltica around its Małopolska promontory/proximal terrane. A complex foreland flysch basin developed in front of the SlavkovRzeszotary suture and across the Rzeszotary-Baltica/Małopolska border. The further from the suture the less amount of the 640-550 Ma detritalzircons extracted from the Thaya-Slavkov hinter land and the smaller eNd (T) values. In West Małopolska, the flysch contains mainly Neoproterozoiczircons (720-550 Ma), whereas in East Małopolska 1.8-2.1 Ga and 2.5 Gazircons dominate, which resembles nearby Baltica. The basin infill was multiphase folded and sheared; in Upper Silesia prior to deposition of the pre-Holmia Cambrian over step.

New geological, geochemical and U-Pb SHRIMP zirconage data brought more information about basement units in subsurface of Southern Poland and SE Romania, which allows to revise and refine some earlier models in the framework of the break-up of the Rodinia/Pannotia supercontinent. In the Brno Block, Moravia, and in the Upper Silesia Block, three different terranes formed the composite Brunovistulia Terrane. The Thaya Terrane (low eNd (T)) of Gondwana (Amazonia) descent collided obliquely at 640-620 Ma with the Slavkov Terrane (moderate eNd (T)) composed of amphibolitefacies metasediments and arc-related, mostly unfoliated granitoids which intruded at 580-560 Ma. At that time, back-arc rifting separated the couple Thaya-Slavkov (inherited zircons: 1.01-1.2; 1.4-1.5; 1.65-1.8 Ga) that drifted away from Gondwana until collision around 560-550 Ma with the Rzeszotary Terrane, the Palaeoproterozoic (2.7-2.0 Ga) crustal sliver deriVěd from Amazonia or West Africa. Atleast these three units composed Brunovistulia, which occurred at low latitudes in proximity to Baltica as shown by palaeomagnetic and palaeobiogeographic data. Then Brunovistulia was accreted to the thinned passive margin of Baltica around its Małopolska promontory/proximal terrane. A complex foreland flysch basin developed in front of the SlavkovRzeszotary suture and across the Rzeszotary-Baltica/Małopolska border. The further from the suture the less amount of the 640-550 Ma detritalzircons extracted from the Thaya-Slavkov hinter land and the smaller eNd (T) values. In West Małopolska, the flysch contains mainly Neoproterozoiczircons (720-550 Ma), whereas in East Małopolska 1.8-2.1 Ga and 2.5 Gazircons dominate, which resembles nearby Baltica. The basin infill was multiphase folded and sheared; in Upper Silesia prior to deposition of the pre-Holmia Cambrian over step. In Małopolska, the folded flysch series formed a large-scale antiformal stack with thermal anticline in its core marked by low-grade metamorphic over print. In Central Dobrogea, Moesia, Ediacaran flysch also contains mainly 700-575 Ma detritalzircons which link the source area, likely in South Dobrogea with ca. 560 Ma granitoids, rather close with Gondwana. However, fauna in Lower Cambrian over step strata shows Baltican affinity. Such features resemble Upper Silesia, thus Brunovistulia might have extended beeath the Carpathians down to Moesia.

abstract = {The Precambian of Central Europe and adjoining areas belongs to two principal geotectonic domains represented by (1) Baltica that forms a part of the East European Craton (EEC), and (2) peri-Gondwana. Both parts are separated by the Trans-European Suture Zone which is the boundary between the ancient Precambrian lithosphere of the craton and the younger lithosphere beneath the late Neoproterozoic and Palaeozoic peri-Gondwanan mobile belts of Central and western Europe. The peri-Gondwanan units of Central Europe are situated SW of the suture and subdivided into Avalonia and Cadomia, separated by the Rheic Ocean suture. The Baltica part of the EEC consists of three major blocks, namely, Fennoscandia, Sarmatia and Volga - Ural which are characterized by different structures and evolution over a period extending from the Archaean to Palaeoproterozoic. Palaeomagnetic data reveal that Fennoscandia and Sarmatia were separate until c. 1.85 Ga, i.e. until the time of their amalgamation into Baltica. It is assumed that Fennoscandia comprises a mosaic of several Archaean blocks surrounded by accreted crust, generally younging westwards, i.e. in the direction of the Trans-European Suture Zone. These younger orogenic belts include the c. 1.95-1.82 Ga Svecofennian Domain, the c. 1.80-1.65 Ga Trans-Scandinavian Igneous Belt, and a series of 1.75-1.55 Ga magmatic arcs that were variably overprinted during the 1.04-0.97 Ga Sveconorwegian Orogeny. A recent tectonic model suggests the presence of Svecofennian terranes extending across the Baltic and into the Black Sea area. AU parts of Baltica in Central Europe and adjoining areas belong to Fennoscandia (southern Sweden; NE Poland; Lithuania; parts of the basement in the Baltic Sea). Avalonia is a microcontinent or terrane derived from the periphery of West Gondwana. The Neoproterozoic basement of Avalonia formed during Avalonian orogenic processes and related tectonomagmatic events (c. 750-540 Ma). Neoproterozoic and Early Palaeozoic sediments of Avalonia contain detrital zircon grains of Mesoproterozoic age, which are assumed to have formed in a juvenile crust between 1.0 and 1.3 Ga. There is evidence that a large part of Avalonia originated at the margin of Amazonia. Avalonia rifted off from the Gondwanan margin in the late Cambrian/early Ordovician. The Rheic Ocean opened as the Tornquist Sea closed due to the collision of Avalonia with Baltica during the late Ordovician and the early Silurian. In the late Silurian, Baltica plus Avalonia collided with Laurentia coincident with the closure of the Iapetus Ocean to form the short-lived continent of Laurussia. During its drift, and following amalgamation with Baltica and Laurentia, Avalonia represented the northern margin of the Rheic Ocean. Avalonia forms the poorly exposed basement of the Rhenohercynian Zone, extending from the Brabant Massif of Belgium to the eastern margin of the Bohemian Massif. The most important parts of East Avalonia are located in southern Britain and Ireland. Other more easterly parts of Avalonia and related terranes, as well as terranes of uncertain origin along the recent SW margin of Baltica, are summarized as Far East Avalonia. In this chapter, we include the Eckergneiss Complex in the Harz Mountains (Rhenohercynian Zone), the Upper Silesian and Malopolska blocks (SE Poland) and the Thaya and Slavkov terranes, including the so-called Metabasite Belt (eastern Bohemia), as parts of Far East Avalonia. Cadomia is a belt of Neoproterozoic rock units formed by Cadomian orogenic processes at an active margin at the periphery of the West African Craton of Gondwana. Rock units of Cadomia show few or no zircon grains with ages in the range 0.75-1.6 Ga and are dominated by detritus from the West African Craton (2.05 Ga and older). A c. 2.0 Ga crust was recycled. Basement slivers of c. 2 Ga rocks such as the Icartian basement occur locally. The Cadomian basement was formed by Cadomian orogenic processes (c. 750-530 Ma). It includes Neoproterozoic volcanosedimentary complexes and intrusions and early Cambrian (c. 540-530 Ma) plutons intruded during a final intense tectonothermal event. Most probably, Cadomia never left the Gondwana mainland and did not drift off like Avalonia. During the assemblage of the Pangaea Supercontinent by Variscan orogenic events, the Rheic Ocean closed as a result of the continent-continent collision between Laurussia and Gondwana in Late Devonian-Early Carboniferous times. The Mid-German Crystalline Zone at the northern rim of the Bohemian Massif is believed to represent the suture of the Rheic Ocean. The suture was formed by oblique collision between the Bohemian (Cadomia; Gondwana) and Rhenish massifs (Avalonia; Laurussia) in Variscan times during the Late Devonian to Early Carboniferous. During its origin Neoproterozoic crust became recyled and parts of Cadomia and Avalonia amalgamated. Cadomia includes the Armorican Massif, Pyrénées, French Massif Central, Maures Massif, Corsica, and the largest part of the Bohemian Massif such as the Saxo-Thuringian Zone, the Sudetes, and the Moldanubian Zone. The latter contains the Teplä-Barrandian Unit and the Moldanubicum sensu stricto. The oldest units of the Bohemian Massif are remnants of Palaeo- to Mesoproterozoic cratonic basement slivers such as the Dobra gneiss (1.38 Ga) and the Svetlik gneiss (2.05-2.1 Ga). Parts of the Bohemian Massif are related to Far East Avalonia such as the Brunovistulian Block of the Moravo-Silesian Zone (eastern Bohemia) and the Upper Silesian and Malopolska blocks (SE Poland). It is likely that the peri-Gondwanan basement of the Alps also was a part of Cadomia although the occurrence of Mesoproterozoic zircon points to the possibility of an origin west of the West African Craton.},
