Opis:: Fern remains of matoniacean affinity were found in the Lower Hettangian strata of lacustrine/backswamp origin from the Niekłań PGI 1 borehole (central Poland, Holy Cross Mts.). The preserved fragments have been identified as Matonia braunii (Göppert, 1841) Harris, 1980. The remains suggest a rather small, low-growth plant with palmately compound fronds. The sori contain at least 5 sporangia preserved with well-developed annuli. The spores are triangular, trilete and kyrtomate, with a thin and smooth surface corresponding with dispersed Dictyophyllidites mortoni (de Jersey, 1959) Playford et Dettmann, 1965. Based on the gross morphology of sterile and fertile pinnae, suggestions made by Harris (1980) on the synonymy of Phlebopteris braunii (Göppert, 1841) Hirmer et Hörhammer, 1936 with P. muensteri Schenk, 1867 (Hirmer and Hörhammer, 1936) and their referral to Matonia braunii is proved and confirmed in this paper. The fern occurs in strata indicating a warm and humid climate and approaching transgression resulting in a high water table and the enhanced accumulation of organic matter.

Opis:: No Vendian or lowermost Lower Cambrian deposits have yet been encountered in the Holy Cross Mts. and Nida Trough. The Cambrian of the Holy Cross Mts. is represented by Lower, Middle and Upper Cambrian deposits, containing both macro- and microfossils. The Lower Cambrian begins with deposits containing a non-trilobite fauna that does not allow precise age determination. The overlying Cambrian deposits are subdivided on the basis of trilobite faunas. Unfortunately, the species are often endemic, and correlation with the Scandinavian biostratigraphic scheme is limited.

Opis:: Lower and Middle Buntsandstein sediments from the northern part of the Holy Cross Mountains (Central Poland) were studied palaeomagnetically. The obtained palaeomagnetic pole fits well to the Early Triassic segment of the stable European apparent polar wander path. This indicates that there were no detectable horizontal tectonic rotations in this part of the Holy Cross Mountains after the Early Triassic. In the lowermost part of the Buntsandstein sequence (the A0 and A1 units) the basal Triassic normal polarity zone was identified, whereas a reversed polarity dominates in the youngest rocks of the studied sections. This predominantly reversed part can be correlated with the Pomorze Formation (lower part of the Middle Buntsandstein). The correlation of these magnetic polarity records with magnetostratigraphic data from the other parts of the Central European Basin as well as from the Tethyan sections shows that in the studied area, the Permian-Triassic boundary should be placed near the boundary between the Top Terrigenous Series (uppermost Zechstein) and the A0 unit (lowermost Buntsandstein). In the German part of the Central European Basin the Permian–Triassic boundary coincides with the boundary between the Lower and Upper Bröckelschiefer. The Buntsandstein rocks from the localities of Wióry and Sosnowica contain numerous vertebrate tracks. According to the results of magnetostratigraphic correlation they are of Dienerian (Early Triassic) age.

Opis:: The Klonów Anticline is located in the western outskirts of the Łysogóry Region of the Holy Cross Mountains. A fresh look onto the cartographic evidence suggests that this structure shows the key characteristics of a progressive unconformity. This becomes evident when compared to the classical example of the Sant Llorenç de Morunys Anticline (eastern Pyrenees, Spain). The geometry of the unconformity requires a phase of thrusting or reverse faulting along the Holy Cross Fault in the latest Silurian–earliest Devonian (Late Caledonian deformation) followed by Variscan thin-skinned thrusting. Thick- and thin-skinned kinematic scenarios for the latest Silurian-earliest Devonian deformation of the Łysogóry Region are explored.

Opis:: Five sections from the Kielce Region of the Holy Cross Mountains and one core from a borehole drilled in the nearby western Mesozoic Margin reveal the best recognized beds from the Devonian/Carboniferous boundary interval. In four sections: Ruda Strawczyńska, Bolechowice IG 1, Zaręby IG 2 and Kowala, the Devonian/Carboniferous boundary is located within a continuous series of deep-water carbonates, whereas in the two remaining: Ostrówka Quarry and the Jabłonna IG 1 borehole, the Devonian/Carboniferous boundary interval contains stratigraphic gaps resulting from lack of deposition in submarine conditions. The biostratigraphic position of the analyzed uppermost Devonian and lowermost Carboniferous beds is determined by assemblages of conodonts, microspores and deep-water ostracodes of the Thuringian ecotype. The lithology and biostratigraphic position of particular beds in the Devonian/Carboniferous boundary interval of the Kowala section from the western part of the Holy Cross Mountains resemble those in a succession of equivalent age from the Rhenish Massif. Both areas are characterized by similar lithological horizons and changes of biotic assemblages within the same conodont zones. Strata and fauna from the uppermost Famennian are influenced by the global regressive Hangenberg Event.

Opis:: Palaeomagnetic studies of Middle and Upper Devonian carbonate rocks in the Holy Cross Mts. (Central Poland, SW foreland of the East European Craton - EEC) involved samples from the southern (Kielce) and northern (Łysogóry) unit. Haematite-bearing carbonates showed syn-folding remagnetisation of Early Permian age. The pole of this component is situated on the apparent polar wander path (APWP) of the EEC. The syn-folding age implies deformation of the Variscan syncline during Alpine uplift of the Holy Cross Mts. In dark limestones and dolomites magnetite was a dominant magnetic mineral. The age of magnetisation is interpreted as pre-Late Carboniferous: syn-folding in one locality and either pre- or syn-folding in four others. Four poles calculated from these components are shifted to the NW from the reference southern APWP for the EEC and one pole is concordant with its Early Carboniferous segment. The occurrence of rotated and unrotated palaeomagnetic poles could indicate that some fragments of both Kielce and Łysogóry units were subjected to local clockwise rotations during Variscan compression. An alternative explanation might be that Variscan pre- and/or syn-folding components could be strain modified or resultant magnetisations and they should not be used in palaeotectonic reconstruction.

Opis:: The palynology of the Cambrian claystones and mudstones of the Góry Pieprzowe Shale Formation in the southern part of the Łysogóry region (Holy Cross Mts., Poland) are described. These deposits had been referred to the Middle Cambrian of the Paradoxides paradoxissimus and Paradoxides forchhammeri Superzones. Here, rocks from 10 shallow drillings and several exposures in the Opatów region have been examined. Scarce and poorly preserved acritarch assemblages contain several forms that are indicative for the Upper Cambrian, while the genera Acanthodiacrodium, Cymatiogalea, Stelliferidium, Trunculumarium, Nellia, Impluviculus, Calyxiella, and Veryhachium excludes the possibility of a Middle Cambrian age. Rather, these forms suggest the Upper Cambrian, most probably its middle and upper part. The occurrence of the rocks of this age to both north and south of the Łysogóry quartzite outcrops indicates tectonic repetition of the geological structure in the Main Range of the Holy Cross Mountains.The dark colours of palynoflora from the Pieprzowe Mountains in Sandomierz are identical with the colours of the Cambrian microflora from the Łysogóry region, and differ from the bright colours characterising organic matter in the Kielce region of the Holy Cross Mountains. This suggests a tectonic relation of the Pieprzowe Mountains with the Łysogóry region rather than with the Kielce region, as hitherto thought.
