Sulfate mineralization occurs in almost all lithostratigraphic beds of the Carpathians and has been described for at least the last century. While carrying out cartographic studies near Bobowa, a new site of gypsum mineralization was discovered within the hieroglyphic beds of the Jankowa anticline. The gypsum crystals found there reach up to several centimetres in length and, so far, no similar ones have been described in the Carpathian flysch deposits. Gypsum from Jankowa occurs in the form of intergrowth and twinnings, rosettes and larkspurs, and vein fillings.

11 specimens of large sized ammonites from the Štramberk Limestone deposited in the collections in Prague represent 6species. Two species belong to the superfamily Lytoceratoidea, the remaining ones to the superfamily Perisphinctoidea. The perisphinctid specimens belong to the Lower and the Upper Tithonian, and the lytoceratids probably correspond to the same stratigraphic level. Two species, namely Ernstbrunnia blaschkei and Djurjuriceras mediterraneum were not known from the Štramberk Limestone earlier.

In the Late Jurassic to Early Cretaceous palaeogeography of the Alpine Tethys the term Ocean is used for different parts of these sedimentary areas: eg. Ligurian – Piedmont and Penninic, Magura, Pieniny, Valais and Ceahlau-Severins oceans. The Magura Ocean occupied the more northern position in the Alpine-Carpathian arc. During the Late Cretaceous–Paleogene tectono-sedimentary evolution the Magura Ocean was transformed into several (Magura, Dukla, Silesian, sub-Silesian and Skole) basins and intrabasinal source area ridges now incorporated into the Outer Western Carpathians.

The paper presents the first example of Holocene faults in the OuterWestern Carpathians in Poland. Small-scale normal faults at Koninki, Gorce Mts., cut both Palaeocene strata of the Ropianka Formation of the Magura Nappe and overlying coarse-clastic bedload facies of Holocene alluvium that builds a 5-5.5-high terrace step of a small valley. These NE-trending faults are accompanied by reorientation of clast a-b planes subparallel to fault planes and by clast fracturing. Such deformations must have been induced by relatively strong earthquakes, unknown from historical record of the Outer Carpathian seismicity. Fault attitude points to NW-oriented axis of the minimum principal stress, which is compatible with parameters of the present-day stress field in the Outer Western Carpathians of Poland.

Przedmiotem niniejszego opracowania jest budowa petrograficzna uwęglonej lądowej materii organicznej w skałach fliszu Karpat Zachodnich. W trakcie analizy petrograficznej materię organiczną podzielono na odmiany, mając na uwadze rozmiar szczątków organicznych. Materia organiczna reprezentowana jest przez DOM (Dispersed Organic Matter) i uwęglony detrytus roślinny. Ustalono, że zarówno DOM, jak i detrytus nie występują w skałach grubookruchowych, takich jak piaskowce gruboziarniste i zlepieńce. We wszystkich próbkach zawierających materiał węglowy dominuje grupa witrynitu, stanowiąca od 70% do 100% materii organicznej, przy udziale grupy inertynitu w zakresie od 0 do 30%. W trakcie badań próbek w świetle ultrafioletowym w żadnej nie stwierdzono macerałów grupy liptynitu. Największy udział w próbce całkowitego węgla organicznego TOC (ang. Total Organic Carbon) od 1.09% do 8.2%, wykazały warstwy krośnieńskie, grybowskie, formacja szczawnicka, beloweska i wierzowska. Wartości średniej refleksyjności witrynitu w poszczególnych jednostkach są do siebie zbliżone, choć w obrębie jednostek są silnie zróżnicowane i wyniosły odpowiednio: 0.39-0.62% w jednostce śląskiej, 0.38-0.71% w jednostce magurskiej i 0.42-0.67% w jednostce grybowskiej. Najwyższe wartości odnotowano w oknie tektonicznym Mszany Dolnej (0.67%) oraz w południowych partiach jednostki magurskiej (0.65-0.71%).

The objective of this study was a petrographic analysis of terrestrial organic matter in the Western Flysch Carpathians. During the petrographic analysis, organic matter was divided with respect to the size of organic remains into two types. Organic matter is represented by the acronym DOM (Dispersed Organic Matter) and coalified detritus. It was found that both DOM and detritus do not occur in coarse grained rocks, such as coarse sandstones and conglomerates. Vitrinite is the dominant component in all samples, it constitutes 70% to 100% of the organic matter content, whereas the inertinite group makes up the remaining 0% to 30%. No exinite group macerals were detected during fluorescence microscope analysis. Krosno beds, Grybów beds, Szczawnicka, Beloveza and Verovice formation revealed the greatest contribution of TOC (Total Organic Carbon) in the sample, which was from 1.09% to 8.2%. The random mean vitrinite reflectance values in the individual units are similar and vary from 0.39 to 0.62% in the Silesian unit, 0.38% to 0.71% in the Magura unit and 0.42% to 0.67% in the Grybów unit. The highest values were observed in the Mszana tectonic window (0.67%) and in the southern parts of the Magura unit (0.65-0.71%).

Organic matter in the Istebna beds occur as dark laminas in sandy mudstones. Coalification degree of organic matter in the Istebna beds is related with orogenic period of the flysch Carpathians. There is no correlation with age of rocks and subsidence processing started during Paleogene. Higher values of vitrinite reflectance in southern part of Silesian Unit have been noticed.

Sedimentological development of the Verovice Formation (Czech Moravia) is presented, according to Early Cretaceous geotectonic-eustatic changes in the proto-Silesian Basin. Those processes were a consequence of a gradual rebuilding the architecture of the Alpine-Carpathian realm. The geological events well correspond with the global sequence stratigraphy.

The Early Cretaceous ammonites from the Hradiste Formation (Wernsdorfer Schichten in original concept) in the Czech part of the Silesian Unit of the Outer (Flysch)Western Carpathians are described. This rich material, collected over more than 40 years, includes many usually fragmentarily preserved ammonites. The majority of specimens are preserved as "half-ammonoids"; a small portion of them have pyritized inner whorls with preserved suture lines. 15 species-level taxa are described, partly in open nomenclature. One species, ?Valdedorsella hoheneggeri, is described as new; albeit its generic classification remains uncertain. The ammonites described span the late Early Barremian (Niclesia pulchella ammonite Zone) to basal Aptian (Deshayesites oglanlensis ammonite Zone).
