    Opis:
    The Upper Jurassic limestones in the vicinity of Cracow underwent extensive dedolomitization process. Petrographic and cathodoluminescent analyses of carbonates in four test areas confirm the dedolomitization as have been developed with various intensity. The alteration of dolomite into calcite occurs as centripetal and centrifugal dedolomitization. Both processes lead finally to a complete disintegration of the dolomite crystals; calcite pseudomorphs after dolorhombs are the end products. These calcite pseudomorphs are abundant in limestones of St. Anna Mt. and in the Kostrze quarry, but are scarce in the Twardowski Cliffs area and in the outcrop of Księża Mt., which indicates a less advanced and slower dedolomitization process in the latter two areas. Most probably the initiation of dedolomitization started from the moment when a carbonate bank emerged from the sea water (Vierek, 2003); temperature of mixing fluids decreased considerably, whereas Ca 2+/Mg+- ratio in the same fluids increased.

    Upper Jurassic
    Opis:
    The Callovian and Upper Jurassic strata in the Nida Trough are similar to those from SW margin of Holy Cross Mountains, so the same lithostratigraphic pattern may be applied. Three facies zones are distinguished: NW, central and SE. Black deposits of the Middle Jurassic are covered by the Sandy Limestones and Marls (lower Callovian–Bukowskii Subz. Cordatum Z.). Locally, these strata are separated by the Calcareous Sandstones (uppermost Bathonian–lower Callovian). The Marly Limestones and Marls represent Bukowskii Subz. Cordatum Z.- Plicatilis Z. The Morawica Limestones represent Plicatilis Z.–Bimammatum Z. The Siedlce Limestones (facies: pelitic, pelitic-sponge, pelitic-coral) reach the Platynota Z. in central andNWpart and the top of Hypselocyclum Z. in a narrow zone in SE part of Nida Trough. The Chalky Limestones (facies: pelitic, biostromal) are equivalents of the uppermost Siedlce Limestones in the centre of the Nida Trough. Beyond this narrow zone in the SE part of the Nida Trough, the Lowermost Marly Horizon (Platynota Z.) and deposits of shallow water carbonate platform (Platynota Z.–Hypselocyclum Z.), Lower & Upper Oolites, Banded Limestones, Oolite-Platy Member, Platy Detrital Limestones, Platy Limestones and Underlying Shales are distinguished. The uppermost part of the incomplete section (Divisum Z. and Mutabilis Z.) is represented by the Skorków Lumachelles and Upper Platy Limestones in the entire Nida Trough while the Staniewice Lumachelles occur in its SE part. The knowledge of the Middle– Upper Jurassic deposits of the Nida Trough is important for palaeogeographical reconstructions of the whole Southern Poland, as the Nida Trough links other regions where the Jurassic deposits are well recognized in numerous outcrops and borehole sections.

    Opis:
    Three objects were studied within a project aimed at investigation of stones used in the Romanesque edifices in the vicinity of Kraków, and continued since 2019. These are the churches in Dziekanowice (21 km SE of Kraków) and in Czchów (58 km SE of Kraków), and a clergy house in Morawica (13 W of the Kraków city centre). The church in Dziekanowice is relatively completely and well preserved, while the only Romanesque remnants of the church in Czchów are those reused in the Gothic church. It is a clergy house in Morawica (a former castle), whose walls contain Romanesque fragments. Two former edifices are built of the Istebna sandstone (Upper Cretaceous-Paleogene), quarried from the local flysch bedrock. Fine-grained, grey-yellowish stone dominates. It is soft and easily workable due to argillaceous binder (matrix). The stone blocks are precisely shaped and well fitted. Romanesque remnants of the clergy house in Morawica are con- structed predominantly of limestone, also of local origin. Only a fragment of the NW wall is built of the Istebna sandstone. This fragment is probably a part of the butress supporting the NW wall. The study shows that stonemasons and builders of that time had good skills of selecting and applying proper stone blocks for particular purposes. Blocks used in load-bearing structures were exceptionally well shaped and fitted. On the other hand, those skills varied. The frieze from the Romanesque church in Czchów is rather primitive. The size of limestone blocks used in the clergy house in Morawica is strikingly similar to those of various Romanesque edifices in Kraków. It seems, therefore, that those blocks could have been quarried and shaped in quarries located in the city, where the masonry “industry” was well developed. Larger, irregular blocks, used as foundations and filler in the “opus emplectum” type walls were probably quarried on site. Moreover, stones used in more eminent edifices (churches, castles) were probably more carefully selected. The Morawica castle (clergy house) and many churches in Kraków were built of limestone blocks without cherts.

    Opis:
    The Owadów-Brzezinki quarry is one of the most important paleontological sites in Poland, known from its exceptionally well-preserved Late Jurassic (Tithonian) fossils of marine and terrestrial biota, including horseshoe crabs and decapod crustaceans, rare ammonites, various insects and pterosaurs. This paper describes the discovery of new, well preserved reptile bones (ichthyosaurs, turtles and crocodylomorphs), which adds sigmficantly to our knowledge of these three gr°upü. The occurrence of large marine reptiles show open marine connections with the Sub- boreal-Boreal areas (both with Subboreal English seas and Boreal Arctic areas), and the Submediterranean Province (corresponding to the area of southern Germany).

    Opis:
    Vertebrate remains, mostly cryptodiran turtle shellfragments, pliosaur skull bones and teeth, plesiosaur vertebrae and crocodylomorph isolated teeth and skull fragments are described from the Upper Jurassic (Kimmeridgian) limestone beds of Krzyżanowice in the NE margin of the Holy Cross Mountains in Poland. The vertebrate fossils were collected during the palaeontological excavations conducted in 2018 and 2019 by the authors, and in the 1960s by a scientific team from the Museum of the Earth and the Institute of Paleobiology Polish Academy of Sciences. All osteological remains are generally very well preserved. This interesting vertebrate bones association from the upper part of the Kimmeridgian represents fossils of animals from two different types of environment. The first contains costal reptiles, like turtles and crocodylomorphs, the second one contains large pelagic animals - pliosaurids and plesiosaurids. This new vertebrate fauna from Poland has been correlated with age-equivalents from other regions of Europe and both Boreal/Subboreal and Mediterranean palaeobiogeographical realms.

    Opis:
    In this paper, two scenic caves, five selected karst rock forms, and five rock outcrops situated in the Ojców National Park and its protected zone area are the subject of comparative research, considered as very essential examples of geotouristic potential. Most of their karst forms differ between each other. These include Łokietek and Ciemna (Dark) cave, Kraków Gate, Rękawica and Igła Deotymy rock-cliff at Ojców, Duży Pochylec rock-cliff in Skała, and Maczuga Herkulesa rocky tower at Pieskowa Skała. Apart from them, outcrops of Quaternary calcareous tufa and rock falls at Ojców, an abrasion surface cutting Upper Jurassic limestones and covered with Cretaceous limestones and marls, Pleistocene loess at Januszowice, and the Duże Skałki (Big Rocks) former quarry of Upper Jurassic limestone at Czajowice were also studied. All of them are situated in the Silesian-Kraków Monocline. The caves, rock-cliffs and Maczuga Herkulesa rocky tower developed in the Upper Jurassic Oxfordian massive limestone. Their karst forms are diverse and picturesque. The other objects selected for research are also very interesting and important examples, displaying products of very complex geological processes. The comparative geotouristic potential evaluation of all 12 objects was made to meet tourists', educators' and investors' expectations and needs to increase their geotouristic development level. The statistical data of the annual number of visitors at the described two caves is also discussed. In general, interest in them as geotouristic abiotic nature objects has been growing regularly until today. They have become very widely known in Poland. Moreover, the Łokietek Cave, Kraków Gate rock-cliff and Maczuga Herkulesa rocky tower have become very popular worldwide.

    Opis:
    Benthic foraminifera, tintinnids and calcareous dinocysts provide new important biostratigraphic data on the age of the Raptawicka Turnia Limestone Formation and Wysoka Turnia Limestone Formation of the NiedŸwiedŸ crag geological section in the Polish Western Tatra Mts. Foraminiferal assemblages of shallow- water limestones from the NiedŸwiedŸ section contain some stratigraphically significant species, including Haghimashella arcuata (Haeusler), Protomarssonella kummi (Zedler), Uvigerinammina uvigeriniformis (Seibold & Seibold) and Textulariopsis jurassica (Guembel). Sporadic planktonic microfossils, such as the tintinnid Tintinnopsella carpathica (Murgeanu & Filipescu), calcareous dinocysts (Cadosina minuta Borza, Colomisphaera lucida Borza, C. tenuis (Nagy), C. varia Øechanek and Parastomiosphaera malmica (Borza), have also been identified. On the basis of these microfossil assemblages the lower and middle parts of the NiedŸwiedŸ section was dated as the Lower Tithonian–Barremian. Limestones of the Raptawicka Turnia Limestone Formation section represent peloidal, peloidal-oolitic and peloidal-oolitic-bioclastic facies. Limestones from the Wysoka Turnia Limestone Formation of the NiedŸwiedŸ section was dated as the Upper Barremian–Lower Aptian, based on a specific composition of foraminifera assemblages, that suggest an eroded carbonate platform as a source of Urgonian-type carbonate material. The boundary between the formations occurs within a poorly dated interval (Valanginian–Barremian).

    Opis:
    Rare-earth elements (REE) were determined for the Upper Jurassic limestone and dolomites from the following outcrops: Góra OEw. Anny, Kostrze Quarry, Księża Góra, and Skały Twardowskiego. REE patterns are similar for all the investigated samples. Dolomites and limestone are enriched in light REE, they exhibit positive La anomalies, and negative Ce and Eu anomalies. Negative Ce and Eu anomalies are typical for oxidizing environments during dolomitization processes. Distinct enrichment in light REE comparing to heavy REE indi-cates that the sea water was not the only component of dolomitization fluids.

    Opis:
    The paper is an attempt to evaluate the geological and quarrying conditions of the Blessed Salomea “marble”. Its physico-mechanicalproperties were determined in relation to the lithology. The probable volume of excavated rock material was compared to the volume of the small architecture elements, mainly altars and tombstones made of this stone. The comparison indicates that the rocks with similar colour and physico-mechanical properties occur also within other outcrops of Upper Jurassic limestones in the vicinity of Cracow. The “marble” of Blessed Salomea is distinguishable due to its otherfeatures. Besides the ability to take polish, these include the possibilities of cutting very large blocks and ability to be carved for figural and ornamental sculpture. These characteristics are related to the homogeneity caused by the large amount of micrite. So far, no other Jurassic limestone with these distinguishing properties has been found.

    Opis:
    The main task of research was a quantitative and qualitative identification of rare earth elements within various Mesozoic sediments in the surroundings of the Holy Cross Mountains. Over 100 samples from archive boreholes, outcrops and mining waste were analysed using modern methods, like portable XRF, geochemical analysis (ICP-MS), electron microprobe and SEM. Results show enrichments of REE concentrations in sedimentary rock samples from the Niektań PIG-1 borehole (LREE up to 0.95%), Miedary outcrop (LREY up to 0.4%) and Lower Cretaceous phosphorites from mining waste in Chałupki and Annopol (LREE ~0.2%). Further investigation is strongly recommended in order to explain the distribution of REE in the study areas.
