    Opis:
    The Inowrocław salt dome can be considered one of the model structures in the Polish Lowlands. Salt structures formed as the result of halotectonic and halokinetic action. The Permian salt was squeezed upwards from deep geological levels due to the overburden load, using fractured zon es and faults. The salt dome is presented as a dynamie three- A Piątkowska K Czuryłowicz M Przyłucka -dimensional geological model developed using advanced technology to create and visualize 3D spatial data. Thanks to the relationship between the dynamics of the land surface and natural geological processes, the results and conclusions can be quickly drawn. For this purpose, average values of displacements in mm peryear, obtained by Satellite Radar Interferometry - Persistent Scatterers (PS) for the time span 1992-2006, are presented in the form of interpolation, creating a surface ofground movement (subsidence and uplift) above the Inowrocław salt dome.

    Opis:
    The possible occurrence of the Oldest Halite (Na1) unit of the Zechstein PZ1 cyclothem in the Kłodawa salt dome was a discussed matter for many years. Profiling and sampling of the evaporite Zechstein succession (a transition of PZ1 to PZ2 cyclothems) visible in a corridor of the "Kłodawa” Salt Mine at the mining level -650 m, located near the NE marginal pillar of the dome, were done in 2011. The studied section includes rock salt, shale, sulphate and carbonate rocks inclined at 60-90o to the NE and represents a normal succession of the PZ1 and PZ2 cyclothems. The normal succession of the top part of the PZ1 cyclothem consists of two lithological units: 1) rock salt complex (extending over a distance of ca. 5.8 m), defined as the Oldest Halite (Na1) lithostratigraphic unit, and 2) anhydrite bed, c.a. 1.3 m thick, distinguished as the Upper Anhydrite (A1g). These deposits are overlain by 4 lithological units, considered as those creating the normal sequence of the lower part of the younger PZ2 cyclothem. The first one is a dolomitic shale bed, ca. 3.7 m thick, defined as the Stink Shale (T2). It is overlain by a dolomite layer, 0.3-0.5 m thick, representing the Main Dolomite (Ca2), and by an anhydrite series, over 17 m thick, attributed to the Basal Anhydrite (A2). The studied section ends with a rock salt complex, ca. 4 m thick, interpreted as the Older Halite (Na2). The bromine (Br) content in both salt units is relatively low: 81-86 ppm (7 samples) in the Na1 unit and 54-77 ppm (4 samples) in the Na2 unit, with a distinct upward-increasing trend in the latter. Similar low Br values and their distribution trends were characteristic for the top of the Na1 standard bromine curve in Poland and for the lower part of such curve for the Na2 salts. This geochemical similarity could support a proper stratigraphic position of both units. The analysed section was interpreted as a tectonic slice or intrusion, composed of Na1 rock salt overlain with the younger A1g sulphate, incorporated within the folded complex of Na2 rock salt. Such image confirms the current opinion of a more complicated internal structure of the so-called "marginal anticlines” within the Kłodawa dome, composed of intensively folded both salt units. It also documents that the oldest Zechstein evaporites (chlorides and sulphates) could occur above within the dome section than was stated earlier.

    Opis:
    The paper presents results of long-standing geodetic measurements including the most recent results of levelling measurements carried out by the authors. Based on the results, a model of ground surface movements was created, which roughly reflects contemporary tectonic activity of the Inowrocław salt structure. The performance of vertical displacements of benchmarks of the research network for the last quarter-century shows its significant mobility. The results of measurements were discussed in the context of the state of art of tectonic mobility of the area and the geological structure of the dome. Unusual agreement in rates of geological processes (salt diapir uplift) determined by geodetic measurements and estimated by geological methods for a long time interval confirms trueness of previous ideas about contemporary diapir movements of the Inowrocław Salt Dome. Repeated levelling evaluated for two last time intervals provided similar regions and rates of uplifts, giving additional control of reliability of the measurements.

    Wapno Salt Dome
    Opis:
    Stylolites have been found in a core sample from the gypsum cap rock of the Wapno salt dome (figs 1-3) at a depth of 40 m below the land surface. These structures are inclined at 40-45ş to the core axis and cut by neomorphic gypsum crystals. Stylolites are products of the solution pressure. They commonly occur in carbonates but are very rarely encountered in evaporates, thus the origin and preservation of these structures in the cap rock of Wapno dome are interesting problems. Lithostatic pressure near the surface where the cap rock has been formed is insufficient to develop stylolites. Thus stylolites (fFigs 4-5) in gypsum cap rock of the Wapno salt diapir are probably early diagenetic structures preserved in a fragment of Zechstein anhydrite of Z2 or Z3 cyclothems. This anhydrite block with stylolites have been carried inside intruding salt masses to the top ofWapno dome. Halite and other easy soluble minerals had been dissolved, but the anhydrites with preserved stylolites have been incorporated in the cap rock and secondary altered into gypsum, similarly to the phenomenon found in Gorleben Salt Dome by Bäuerle et al. (2000).

    Opis:
    In July 2003 and 2004 small groups of geologists of AGH — The University of Science and Technology in Kraków investigated recent Andahua volcanic formation of Southern Peru. It was identified first some 45 years ago but its extension is not definitely determined yet. Field work resulted in discovery of about 100 individual emission centres: apparent pyroclastic cones 50–300 metres high, and usually smaller lava domes and vents by controlled fractures. Morphology of the Andahua lava flows coalescing into composite lava fields as well as criteria for their stratigraphy and tectonic controls are given.

    Opis:
    The Dębina salt dome is situated in central part of the Tertiary Kleszczów Graben, central Poland. Cap rocks of the dome were characterized on the basis of analysis of core material from a well drilled in the northern part of that structure. The cap rock sequence may be subdivided into two parts. Its lower part with breciated structure represents residuum from dissolution of saline series whereas the upper comprises rocks developed by coalescence of shale cover with gypsum. Gypsum rocks of the cap form 6 lithotypes. In these lithotypes it is possible to distinguish: 1) recrystallizational structures developed during diagenesis and multiple hydration transformations, 2) structures developed in a local stress field related to displacements evoked by dissolution of the cap rocks and fluid circulation. Structures of the first type include microcrystalline gypsum with anhydrite relics and carbonate nodules, lenticular and acicular gypsum, porphyroblastic and even-grained gypsum as well as vein gypsum and first generation of stylolites. The other type of structures is represented by: gypsum showing shape fabrics and associated gypsum nodules, gypsum grains with geometry of -clasts, fibrous gypsum in pressure shadows, structures of the core-and-mantle type, subgrains developing in bigger crystals and second generation of stylolites and slickolites. Five sets of fractures were recorded. These fractures developed in the cape rocks under stress field with the vertical maximum stress axis and active shear planes. The normal faults of B, C and D sets could be formed during upward motion of the dome, its stagnation, or during gravitational collapse triggered by karst processes. Oblique striations on microfault B surfaces point to later reactivation under local normal-slip regime caused by ongoing subsidence of the cap rocks, or alternatively - a reactivation that occurred in response to external stress field which controlled evolution of the extensional Kleszczów Graben.

    Opis:
    The paper presents tectonic considerations on the geology of the Orlica-Śnieżnik Dome (OSD), based on the published geotectonic, structural and kinematic data and reports on the OSD geotectonic setting, relating to the evolution of the Variscan collisional belt. Further progress has been done in the recognition of the structure and evolution of the OSD, and for many decades the dominant structural geology has been replaced with multithreading researches. However, the current tectonic interpretations are matched against pre-established schemas of structural evolution of the OSD. The OSD is most likely a fragment of the Moldanubian Terrane with the Variscan collisional sutures. The dextral transpression in a general shear regime and with the participation of strain partitioning has formed a thrust sheet package with the dominant tectonic transport top-to-the NNE, N and NW, with the exception of the NE part of the OSD. The development of regional-scale ductile shear zones in the OSD took place during the progressive tectono-metamorphic evolution from about 360 to 335 Ma. These processes resulted from the highly oblique collision of the Moldanubian Terrane (with the OSD) with the Brunovistulicum on the east and the Tepla-Barrandian Terrane on the W, and with a frontal collision with the Central Sudetic Terrane on the N.

    The paper deals with the problem of anthropogenic changes in the extent of peat deposits, their volume and water retention capacity of raised and valley peat bogs in the Polish part of the Orava-Nowy Targ Basin and the Bieszczady Mts. This problem has not received a great deal of attention in the research literature. Special attention was paid to the remnants of peat domes and post-peat areas. The decrease in the area of peat bogs, the volume of peat deposit and the quantity of water retained within them were estimated for the last ca. 400 years. This paper is based on an analysis of maps produced over the last 230 years as well as aerial photographs. Field data and laboratory data were also analyzed as part of this research.
