Opis:
Listracanthus pectenatus sp. nov. represents the youngest record of the enigmatic chondrichthyan Listracanthus. This new species is the only Mesozoic record of this genus and highlights survival of a rare and enigmatic group of cartilaginous fishes across the Paleozoic–Mesozoic boundary. In the Vega−Phroso Siltstone Member of the Sulphur Mountain Formation (western Canada), two kinds of numerous dermal denticles identified as Listracanthus occur predominantly in strata probably of early Smithian age. The new species differs from all other known species of the genus in the structure of the anterior and posterior borders of the large denticles. The small denticles appear to be less diagnostic than the large ones and are readily distinguished from small denticles generally assigned to the genus Petrodus. Histology reveals that the largest denticles were originally hollow, probably secondarily ossified as acellular bone. The conclusion drawn by previous authors that Listracanthus may be a petalodontid shark, based on ambiguous non−skeletal associations with Deltoptychius, Petrodus, or Calopodusis not supported by this study. The large number of denticles, the size of both types of denticles and their arrangement suggest that Listracanthus pectenatus sp. nov. was a large chondrichthyan of aberrant body shape and yet uncertain systematic position.

Opis:
New magnetostratigraphic data from the Middle Buntsandstein section, drilled in the Brześć Kujawski IG-1 borehole (Central Poland), are presented and discussed. The chronostratigraphic positions of particular formations of the Buntsandstein are discussed as well. The magnetic polarity pattern obtained from the Brześć Kujawski IG-1 borehole matches the pattern obtained earlier in other boreholes from the Polish part of the Central European Basin. Although magnetostratigraphy and palynological evidence undoubtedly indicates that the Induan/Olenekian boundary in the Polish part of the CEB is located in the lower part of the Pomerania Formation, the placement of the Olenekian/Anisian boundary within the sedimentary sequences of the Central European Basin remains problematic. This boundary most probably is located within the upper part of the Upper Buntsandstein, as can be inferred from palynological studies.

Opis:
In the years 2010-2013, analysis of rocks that build the sedimentary covers in Poland was carried out from the point of view of energy utilization accumulated in hot dry rocks – used in Enhanced Geothermal Systems (EGS). As a result of a number of analytical studies, the area situated in the central part of Poland was selected as one of prospective areas for location of EGS in sedimentary rocks. This area encompasses a major part of the Mogilno-Łódź Trough, a part of the Kujawy Swell and a small fragment of the Fore-Sudetic Monocline. The most favourable conditions for development of EGS occur in deposits of the Lower Triassic in the Krośniewice-Kutno vicinity where they are buried to depths greater than 5000 m b.s.l., have thicknesses exceeding 1500 m and are characterized by porosity about 2.5% and permeability about 0.1 mD. In the selected area, thermal characterization of the formation was carried out for location of the EGS in sedimentary rocks. The temperature at the top of Lower Triassic reservoir is in the range 165-175°C. Characterization of petrophysical parameters constituted the basis for further modelling of EGS utilization in selected area.

Opis:
Romanesque collegiate church in Opatów (south-eastern Poland) belongs to the best-preserved Early Mediaeval edifices in Poland. Its date of origin, founder, architects and history are still unclear despite numerous investigations carried out since the beginning of the 19 th century. It is clear that local sandstones were used in the construction of the impressive church. Present investigations resulted in the inventory of the stones used as a building material: their petrography, size of blocks and strange holes and striae on some of their surfaces. Dominant sandstones have different colours: white-greyish or grey-brownish. They are built of very fine-grained, well sorted quartz with siliceous-clayey binder. All sandstone blocks have similar heights (most frequent average 34–38 cm), but different lengths. Longer (up to 62 cm) are placed in the oldest parts of the edifice, shorter (up to 48 cm) form younger fragments and might have been reused after destruction of previous undefined buildups. The sandstones represent Lower Jurassic sediments exposed currently on the slopes of the Opatówka River valley in Podole, some 5 km NE of Opatów. Only a few sherry (reddish) sandstone blocks found in various parts of the walls are probably replacements during post-Romanesque reconstructions. They represent Lower Triassic sandstone from Lipowa, 3 km NE of Opatów. Lancetoidal grooves, 5–20 cm long, and hemispherical holes of 1–4 cm in diameter are apparently of anthropogenic origin (apotropaic marks); however, their purpose is unclear. It is supposed that the grooves are traces of tool sharpening or grinding, while the holes are places where sandy or dusty material was acquired for magical or medical purposes.

Opis:
Despite years of research, Lower Triassic deposits of the epicontinental Central European Basin still lack a detailed stratigraphy that would allow regional correlation of isochronous horizons. The best chronostratigraphic results have up to now been achieved by microspore-based biostratigraphy and magnetostratigraphy. Integrated palynostratigraphic and magnetostratigraphic investigations, carried out on Buntsandstein cores from northeastern Poland representing the eastern margin of the basin, have made precise correlations with the better-explored basin centre. The Lidzbark and Malbork formations of the Bartoszyce IG 1 borehole were examined by means of palynology and palaeomagnetic studies. Further palaeomagnetic studies were applied to the Lidzbark, Malbork and Elbląg formations of the Nidzica IG 1 borehole and the Elbląg Fm. of the Pasłęk IG 1. Two spore-poll en assemblages were distinguished representing the Densoisporites nejburgii Subzone of the D. nejburgii Zone within the lower part of the Lidzbark Fm. and the lowermost part of the Malbork Fm. Mostly reversed polarity was detected within the lower part of the succession investigated, whereas normal polarity prevailed within its upper part. A normal polarity local zone was correlated with the undivided Tbn6-Tbn7 standard magnetozones of western Poland. The reversely polarized part of the succession corresponds most probably to the Tbr5 standard magnetozone. The base of the Tbn6-Tbn7 magnetozone can serve as a good correlation horizon for regional reconstructions.

Opis:
The authors were the first to attempt to identify the stones used in the architectural elements of the baroque Palace of the Kraków Bishops (built in 1637–1641) in Kielce. The founder of the residence was Bishop Jakub Zadzik of the Korab coat of arms. Despite the vicissitudes of fate, the residence defended itself against major transformations, retaining the original shape and as the decoration of the loggia, and is one of the most beautiful monuments from the Vasa era in Poland. However, the turbulent history of the palace, and especially numerous reconstructions, renovations, transfers of architectural elements as well as modifications and functional changes, caused difficulties in reconstructing the original interior design of the rooms, and especially in determining the periods from which the individual stone elements come. The stone decoration of the original palace was limited to the facade with loggias and figures of Swedish and Moscow envoys, a two-flight staircase and single portals inside the building, as well as the floor and fireplaces in the bishop’s rooms. The floor in the lower hallway and the lower diner room on the ground floor were probably also made of stone. Almost exclusively local stone was used: the so-called Kielce marbles (mainly Bolechowice limestone, “Zygmuntówka” conglomerate and Zelejowa rosa-like calcite) and various types of Lower Triassic sandstones from the Świętokrzyskie deposits. Few elements were made of black Dębnik limestone. Noteworthy is the Sanctuary of Marshal Józef Piłsudski, who was stationed in the palace, together with the legionary staff, in 1914. The interior of the main hall of the sanctuary is made of various types of Kielce marbles, mainly Bolechowice limestone, with elements of white Carrara marble. While the identification of carbonate rocks did not pose any major difficulties, assigning sandstone elements to a specific deposit turned out to be impossible in many cases, e.g. due to lack of comparative material.

Opis:
Partially preserved temnospondyl mandibles from the Late Permian–Early Triassic Buena Vista Formation of Uruguay are referred to the basal stereospondyl taxon Mastodonsauridae. These represent the earliest known members of this group for South America. In most cases, this assignment was based on the characteristic morphology of the postglenoid (= postarticular) area of the lower jaw together with the presence of a hamate process. Comparisons with basal mastodonsaurids indicate that the Uruguayan specimens are phenetically similar to Gondwanan and Laurasian Early Triassic taxa, such as Watsonisuchus, Wetlugasarus, and Parotosuchus. Nevertherless, they display some characters which have not previously been described in Mesozoic temnospondyls. The Permo−Triassic Uruguayan mastodonsaurids support a Gondwanan origin for the group, an event which probably occurred sometime during the latest Permian.

Opis:
The Middle Buntsandstein Subgroup of the Lower Triassic of north-eastern Poland has been investigated in the context of possible marine ingressions into the Central European Basin. To better constrain these, palynofacies analysis and mineralogical analysis of mudstones were undertaken on samples taken from the Lidzbark and Malbork formations penetrated by the Bartoszyce IG 1 borehole, serving as stratotype section of both lithostratigraphic units. Microfacies and geochemical analyses, including C and O isotope analysis, were conducted additionally on oolitic limestones of the basal Lidzbark Formation (the lowermost Middle Buntsandstein), and the boron content was measured on all mudstone samples. Seven palynofacies types are distinguished: types 1 to 3 within the Malbork Formation and types 4 to 7 within the Lidzbark Formation. Types 1 and 2 originated on a floodplain, type 3 probably in a deltaic or barrier setting, and types 4 and 5 in a brackish lagoon or a more open basin, possibly of marine origin. Palynofacies type 6 reflects long transport and reworking, whereas palynofacies type 7 is interpreted as formed due to pedogenic processes. Clay minerals and quartz, accompanied by feldspars, calcite and dolomite are the main components of the mudstones investigated. The clay mineral association consists of illite or a mixture of illite and smectite, and chlorite. The Lidzbark Formation and the lowermost part of the Malbork Formation show less variability in mineralogical composition than the upper part of the Malbork Formation. Smectite admixtures were detected only in the upper part of the Malbork Formation (the uppermost Middle Buntsandstein). The boron content, achieved after aqua regia digestion, ranges from 70 to 121 mg/kg (96 mg/kg at average), oscillating generally around 90 mg/kg. A higher boron content, bound in silicate structure, is associated with the upper part of the Malbork Formation. All major mineralogical and geochemical changes coincide more or less with the transition from the supposed marine to the terrestrial environmental realm, interpreted from lithological and sedimentological observations within the lowermost part of the Malbork Formation. However, diagenetic alteration of the clay minerals, and of the boron content, could not be ruled out. The oolitic limestones, mainly grainstones, contain admixtures of quartz grains and rare bioclasts, the ooids nuclei being peloids or unrecognizable. The carbonates are almost exclusively composed of low-Mg calcite. A high content of Mg and the presence of small amounts of dolomite suggest that the ooids were primarily composed of high-Mg calcite and are comparable with similar Early Triassic deposits in Tethyan settings. The δ13C values range from -2 to +1%o VPDB, fitting well with the known ranges of Lower Triassic marine carbonates. An observed δ13C depletion towards the top of the oolite-bearing part of the section may reflect a local shallowing trend that led to overall salinity decrease. A possible connection with the one of the global oceanic geochemical episodes has to be tested further. The results obtained suggest a marine origin of the lower Middle Buntsandstein deposits studied and document a terrestrial origin for the upper Malbork Formation.

Opis:
The fossil record of temnospondyls in South America has been greatly expanded in the last 10 years, increasing their overall significance. They occur in Argentina, Brazil, and Uruguay, and range from the Guadalupian to the Late Triassic. The Early Triassic temnospondyl record in southern Brazil is mainly composed of fragmentary specimens, usually represented by dermal skull bones from the Sanga do Cabral Formation. Some of these fragments were tentatively referred to Lydekkerinidae and Rhytidosteidae based on their characteristic ridge−grooved “spider−web” pattern of ornamentation. In this contribution we report, for the first time, a temnospondyl skull fragment with pustulated sculpturing pattern, which is tentatively ascribed to Plagiosauridae. This new record could indicate the presence of a new temnospondyl taxon for the Lower Triassic of South America.

Produkcja energii elektrycznej przy wykorzystaniu niskotemperaturowych zasobów geotermalnych jest technicznie możliwa dzięki zastosowaniu technologii binarnych. W rejonie Niżu Polskiego niskotemperaturowe zasoby geotermalne związane są przede wszystkim z mezozoicznymi zbiornikami geotermalnymi. Największy potencjał hydrogeotermalny związany jest z piaskowcowymi utworami jury dolnej, występującymi w rejonie niecki mogileńsko-łódzkiej oraz niecki szczecińskiej, gdzie temperatury w obrębie zbiornika przekraczają 90°C, a potencjalna wydajność otworów wiertniczych jest odpowiednio wysoka (powyżej 50 m3/h). Znaczny potencjał geotermalny związany jest ze zbiornikiem dolnotriasowym centralnej części Niżu Polskiego, jednak ze względu na niskie parametry petrofizyczne skał zbiornikowych perspektywy produkcji energii elektrycznej należy wiązać w przyszłości przede wszystkim z potencjałem gorących suchych skał dolnego triasu, a nie z zasobami hydrogeotermalnymi.
Electricity production using low-temperature geothermal resources is technically possible by binary technology. The major geothermal resources in the Polish Lowlands are associated with Mesozoic aquifers. The greatest hydrogeothermal potential is connected with the Lower Jurassic sandstone in the Mogilno-Łodz Trough and Szczecin Trough, where the temperature inside the reservoir exceeds 90°C and potential discharge of wells is above 50 m3/h. Significant geothermal resources are associated with the Lower Triassic reservoir in the central part of the Polish Lowlands, however, due to the low petrophysical parameters of reservoir rocks, electricity production should be connecting with the petrogeothermal potential.

Opis:
Nineteen samples of uppermost Triassic and Lower Jurassic claystones and mudstones, which were formed in the epicontinental Polish Basin, were analysed by inductively coupled plasma mass spectrometry (ICP-MS) for rare earth elements (REE) and other selected trace elements (Sc, Y, Th, Zr and U). The results indicate that the source of most of the claystones and mudstones studied were sedimentary rocks of the upper continental crust of old cratonic areas, where the protolith had a mainly felsic character. However, in the latest Triassic a characteristic layer formed, implying significant input from mafic volcanic protolith. It was also found that moderately intense chemical weathering usually favoured increased concentration of the rare earths. Extremely strong hydrolysis, related to episodes of very hot and humid climate (greenhouse events), caused conspicuous impoverishment in REE in residual clays. Weathering and recycling processes modified the composition of REE to some extent, but generally did not obliterate the original characteristics of the protolith. In some samples, enrichment in rare earth elements was observed, caused by admixtures of accessory minerals (being a main carrier of REE) and/or increased sorting during recycling.

Opis:
The stratigraphic subdivision of the Lower Triassic in the Polish Tatra Mountains is composed solely of units of Alpine origin set in variable configurations. Unification of the stratigraphic classification over a vast area situated between the Dolomites and the Tatra Mountains is partly an effect of its long lasting integration in one state and within the domain of German-speaking geologists. This subdivision has never been soundly applied to the Lower Triassic of the Tatra Mts. on either palaeontological or any other satisfying basis. It has also lost its ground in its type areas, where other stages of extra-European origin has since long been adopted. Hence, the Werfenian, Seisian, Campilian, as well as the Scythian and the Myophoria Beds need to be definitely removed from the stratigraphic nomenclature and replaced with lithostratigraphic subdivision. The lithostratigraphic units should be implemented within their natural limits, therefore the units that have so far been created in the Slovakian part of the Carpathians should be adopted as it is possible.
