    Polish Lowland
    Opis:
    The paper provides a proprsal to divide the three main Mesozoic hydrogeothermal reservoirs of the Polish Lowlands into regions. The division is based primarily on reservoir efficacy in terms of using thermal waters for heating and recreation purposes. The presented validation of individual regions and sub-regions shows that only some parts of them have a medium or high heating potential. The heating and recreation potentials are limited in many places by the high mineralization of thermal waters.

    Opis:
    The present paper summarizes the issues related with occurrence and distribution of wildfires in the Mesozoic. The main focus is put on occurrence of palaeowildfires during the Mesozoic global events, including Permian-Triassic (P/T), Triassic-Jurassic (T/J) and Cretaceous-Palaeogene (C/P) boundary. The other problems are connected with controversies over oxygene curve during Mesozoic, with special emphasis on Jurassic wildfires and theoretical predictions of low concentrations of atmospheric oxygene.

    Opis:
    The paper deals with the major eastern fault in the Mesozoic substratum of the City of Poznań. In this area, only few boreholes reached the top of the Mesozoic succession. It is the reason why this fault cannot be mapped. Therefore, it is indicated the dependence between the relief of the Mesozoic substratum and the morphology of the lignite seam base in adjacent areas where numerous boreholes reached the top Mesozoic surface. This dependence was best expressed at times when the major fault in the substratum was active after peat sedimentation. Subsequently, the structural map of the base of the first Middle-Polish Lignite Seams, pierced by many boreholes, was analyzed. In this way, using an indirect method, location of the major fault in the Mesozoic substratum of the City of Poznań was quite precisely determined.

    deposition rate
    Opis:
    Analysis of deposition rate were performed for synthetic sections, representing the upper Jurassic to lower Miocene sedimentary fill of the Western Outer Carpathian (WOC) basins. Calculated deposition rates differs in a range of a few orders of magnitude. During Tithonian to Berriasian-early Valanginian tectonic activity of the source areas supplying the Silesian Basin was related to the mechanism of syn-rift extensional elevation and erosion of horsts. General decay of source area activity in Valanginian to Cenomanian time was caused by regional post-rift thermal sag of the WOC. The Barremian to Albian phase of compressional uplift of the source area located north of the WOC lead to increase of deposition rate in some zones of the WOC basin. In Turonian to Paleocene time thick-skinned collision and thrusting took place south and south-west (in the recent coordinates) of the Silesian Basin causing very rapid, diachronous uplift of this zone, referred to as Silesian Ridge, resulting with high deposition rate in the Silesian Basin. At that time supply of sediments to the Magura Basin from south was relatively low, and the Pieniny Klipen Belt was presumably zone of transfer of these sediments. In Eocene the zone of collisional shortening in the WOC system was relocated to the south, causing rapid uplift of the Southern Magura Ridge and intense supply of detritus to the Magura Basin. Thrusting in the Southern Magura Ridge and collisional compression resulted with flexural bending of its broad foreland, being the reason for decrease of activity of both the Silesian Ridge and the source area at the northern rim of the WOC. The Eocene evolution of the Silesian Ridge is interpreted as controlled by both episodic tectonic activity and eustatic sea level changes. Contrasting development of the Southern Magura Ridge and the northern rim of Central Carpathians during Eocene stands for a palaeographic distance between the two domains at that time. During Oligocene and early Miocene a significant increase of deposition rates is observed for the basin in which sediments of the Krosno beds were deposited. This was caused by tectonic uplift of the source at the northern rim of the WOC, as well as the Silesian Ridge and the partly formed Magura nappe. The Miocene molasse of the WOC foredeep basin is characterised by notably higher maximum deposition rates than ones calculated for the flysch deposits of the WOC.

    Opis:
    At the end of the Jurassic and beginning of the Cretaceous in the Western Outer Carpathians (WOC) rift-related extension led to development of: the deep marine grabens with flysch and pelagic sedimentation, the zones of shallow marine carbonate sedimentation, and the elevated horsts, supplying the basins with sediments. Transition to the Early Cretaceous and Cenomanian post-rift thermal sag stage was responsible for a general ceasing of tectonic activity in the source areas and unification of the previous sub-basins. In Barremian–Albian time, the northern, external sources for sediments were uplifted due to compression, presumably caused by the orogenic collision in the Middle and Outer Dacides and/or collision related to subduction of the Penninic Ocean. The Silesian Ridge, rapidly elevated and eroded during Late Cretaceous and Paleocene, is interpreted here as an active thick-skinned thrust belt. Nappe stacking in that area and stress transmission towards foreland caused flexural subsidence of the proximal zone (the inner Silesian Basin) and uplift in the distal zone (including: the outer Silesian Basin, the Subsilesian facies zone, the Skole Basin and the northern sediment source areas). The Eocene alternating shallow marine deposition in the Silesian Ridge and its exposition for erosion is interpreted as controlled by both eustatic sea level changes and episodic tectonic activity. At this time new thick-skinned thrust belt developed south of the Magura Basin, which supplied vast amount of detritus for the Magura Beds. The Eocene tectonic shortening and deformations in the Southern Magura Ridge and development of the accretionary prism caused flexural bending of its broad foreland, subsidence and relative facies unification of the basins and decrease of activity of the source areas located north of the Magura Basin. The Oligocene progress of plates/microplates convergence and relocation of the zone of tectonic shortening towards the north led to compressional uplift of the source areas located both to the north of the WOC basins and to the south of the Silesian facies zone, the later composed of crystalline basement, as well as sediments of the Magura Unit. That sources supplied with detritus the Upper Oligocene–Llower Miocene Krosno Beds, being a diachronic continuation of synorogenic deposition of the Magura Beds. During the Late Cretaceous–Paleogene–Early Miocene, an important tectonic shortening across the WOC took place, accommodated mainly in the source areas. This indicates that the palaeogeographic relationships between the Silesian Basin, the Magura Basin and the Central Carpathian Paleogene Basin were changing during the Cretaceous and Cainozoic. In the time span of Albian to Oligocene in the zone palaeogeographically located between the Magura Basin and the Central Carpathians three separate source areas were active, each characterized by a different geological setting. These sources were replacing each other in time, suggesting significant collisional and/or strike slip reorganisation of the zone during that period. The collision of the WOC evolved in time from thick-skinned mode during the Late Cretaceous–Paleogene to thin-skinned one during the Middle Miocene.

    Opis:
    The Snochowice Beds – the Lower Jurassic gravels and conglomerates – are composed of the fragments of the most resistant rocks: the vein quartz, quartzites, quartzite sandstones and conglomerates, lydites and jaspers. The results of performed investigations allowed to modification of the existing opinion about the source areas. The results of petrographical analysis also allow to compare the group of the Snochowice Beds pebbles to the pebbles of the Lower and Upper Triassic rocks from the Mesozoic margin of the Holy Cross Mountains and the Inner Carpathians. The similarity of the main components: the pebbles of quartzites, lydites and jaspers of the Carpathian Triassic rocks and the Lower Jurassic gravels was the basis to identifying the Bohemian Massif as the source area, which was build mainly of the Paleozoic metamorphic and sedimentary rocks. In the Snochowice Beds pebbles were recognized also parts of rocks similar to the Cambrian rocks underlying the Jurassic rocks on the Upper Silesia Block.

    Opis:
    The attempt to divide the Upper Silesian Block and the Małopolska Block into tectonic units has been based on a general map at scale of 1:1000000, without Permian-Mesozoic and Cenozoic strata. Cartographic, general and monographic works regarding formation of Precambrian basement of both of the blocks have been discussed and presented, and data concerning development of sedimentation, tectonics, and structure of the Paleozoic cover of the blocks were the background for the suggested division. The Upper Silesian Block is a part of a larger unit determined as the Brunovistulicum, which together with the Brno Block are entirely located within the borders of the Czech Republic. The Brunovistulicum and the Małopolska Block vary in formation of Precambrian basement and covering Paleozoic formations, what proves different paleogeographical-facial and paleotectonic development. Current data do not allow determining their southern range, where both units are within the range of the orogeny of the Outer Carpathians and quite possibly in the range of the Inner Carpathians. The boundary of the Brunovistulicum and the Małopolska Block along the part between Lubliniec and Cracow and farther to the vicinity of Bochnia and Nowy Sącz is relatively well defined and documented. It is a narrow Cracow-Lubliniec fault zone, approximately 500 m wide, cutting and moving all rock series of the Precambrian and the Paleozoic. The fault zone of the Odra River probably forms its NW continuation. The following tectonic units have been distinguished in the Upper Silesian Block: 1) Moravian-Silesian Fold-and-Thrust Belt, 2) Upper Silesian Fold Zone, 3) Upper Silesian Trough, 4) Bielsko-Biała Dome, 5) Rzeszotary Horst, 6) Liplas Graben. There is only one tectonic unit distinguished in the Małopolska Block-Kielce Fold Belt, dipping towards NW-SE, along the NE boundary of the block. Paleozoic formations building the unit represent thrust fault structure. In this case, the Kielce Fold Belt significantly varies from the other parts of the Małopolska Block, where Paleozoic formations build numerous small block structures.
