Opis:
An update of the main Devonian pre-Variscan palaeogeographical features of the southern Cantabrian Zone is presented. The approximal locations of these features are recorded in sections studied, with thin, incomplete developments for the highs and thick successions for the troughs. Generally, pre-Variscan palaeogeographical features were affected by Variscan and Alpine orogenic deformations, but with a different impact. Oroclinal bending, tectonic shortening by thrusts, movements along strike-slip faults and bending by folds all affected the Devonian palaeogeographical features, and only an approximation of their location and shape can be given. Nevertheless, the palaeogeography recorded in pre-Variscan sedimentary successions and their relative positions, provide specific, clear and objective evidence of the pre-Variscan elements.

Opis:
Geological mapping in combination with geophysical investigations and borehole analyses show differences of the Pleistocene between the Warmia and Mazury palaeogeographic provinces in NE Poland. The (more western) Warmia province has a crystalline basement that is covered by a folded sedimentary succession of 2-4 km thick. The (more eastern) Mazury province (eastern) has a basement that forms part of the rigid East European crystalline craton, which is covered by a sedimentary cover of only 1-1.5 km thick. Cyclic loading by the Pleistocene ice sheets in this area induced glacioisostatic processes of different intensities, resulting in changing palaeogeographic conditions. The changes were increased by intense neotectonic activity that was induced by the ice sheets in the intermediate zone between the two provinces, stretching along the western slope of the crystalline craton. Significant part of intermediate zone forms a belt of crevasse-infill landforms deposited between the Warmia and Mazury lobes of the last glaciation. Studied deposits reveal a cyclic reactivation of the interlobe zone during the successive Pleistocene glaciations. Considerable variations of the relief of the top-Neogene, vertical discontinuities cutting the Pleistocene and Neogene, stratigraphic gaps within the Pleistocene succession, and thick glaciolacustrine successions result from the vertical neotectonic movements in the intermediate area between the two provinces.

Opis:
The Tithonian ammonite succession at the Owadów–Brzezinki quarry, central Poland shows the presence of Subboreal ammonites of both NE European (“Volgian”) and NW European (“Bolonian–Portlandian”) affinity, making possible the correlation between the relevant ammonite subdivisions. The former are represented by Zaraiskites – Z. regularis Kutek and Z. zarajskensis (Michalski) as well as an early form of Virgatites – V. gerassimovi Mitta which enable the recognition of the upper part of the Scythicus Zone (the Zaraj¬skensis Subzone) and the lower part of the Virgatus Zone (the Gerassimovi Subzone) of the “Middle Volgian”. The latter are represented by Virgatopavlovia, which enables the correlation with the Fittoni Zone of the uppermost “Bolonian”, and by still younger assemblage of small-sized virgatitids – such as V. pusillus (Michalski), showing similarity to Progalbanites albani (Arkell) of the Albani Zone of the lowermost “Portlandian”. The new species established include: Zaraiskites lewinskii sp. nov. which represents a new member of the virgatitid lineage linking an older Z. pommerania (Arkell) with younger small-sized Virgatites, as well as two species of the genus Virgatopavlovia – V. janeki sp. nov. and V. dembowskae sp. nov. The appearance of ammonites of NW and NE European affinity in central Poland resulted from the opening of the new sea routes possibly related with tectonic activity in northern European areas at the transition from Early to Late Tithonian.

Tragophylloceras cf. loscombi (Sowerby) has been found in the Kaszewy 1 borehole (central Poland), in the Upper Pliensbachian strata (Margaritatus Zone, Subnodosus Subzone), assigned to the Drzewica Formation. Hitherto, all ammonite finds in the epicontinental Lower Jurassic in Poland have been restricted to Western Pomerania (NW Poland). This find points to a wider extent of the transgressive event occurring in the late Margaritatus Zone, following widespread regression at the beginning of this zone. Rapid and pronounced sea level changes in the early Late Pliensbachian confirms the hypothesis linking these changes with glacioeustasy.

Opis:
The paper focuses on the taxonomic description of the lower Carboniferous (uppermost Tournaisian to middle Viséan) solitary rugose corals from bedded limestone and shale units in the Flett Formation in the Jackfish Gap (eastern Liard Range), northwestern Canada. The corals described herein include 12 species representing the genera Ankhelasma Sando, 1961, Bradyphyllum Grabau, 1928, Caninophyllum Lewis, 1929, Cyathaxonia Michelin, 1847, Ekvasophyllum Parks, 1951, EnniskilleniaKabakovich in Soshkina et al., 1962, Vesiculophyllum Easton, 1944 and Zaphrentites Hudson, 1941. Two of these species are new (Ankhelasma canadense sp. nov. and Ekvasophyllum variabilis sp. nov.) and 6 taxa are described in open nomenclature. The distribution and relative abundance of solitary Rugosa in Europe and the Liard Basin confirm the geographical proximity of those areas and the open marine communication between them during the early Carboniferous. It therefore represents an important contribution to the determination of the time of isolation of the western Laurussia shelf fauna from that of southeastern Laurussia, as well as the time of the possible emergence of species from southeastern Laurussia into the western Laurussia seas. Of particular importance here are cosmopolitan taxa and the timing of their disappearance from the fossil record.

Opis:
The paper presents the detailed plate tectonic, paleogeographic, paleoenvironment and plaeolithofacies maps for eight Early Paleozoic time intervals. Forty maps, generated using PLATES and PALEOMAP programs, contain information about plate tectonics, paleoenvironment, and plaeolithofacies during Cambrian, Ordovician and Silurian. Disintegration of supercontinent Pannotia and origin of Gondwana, Laurentia and Baltica occur during Early Cambrian. Oceans spreading continued during Late Cambrian and Early Ordovician; vast platform flooded by shallow seas existed on the continents. The plate tectonic reorganization happened during Middle Ordovician. Silurian was a time of Caledonian orogeny, closing of Early Paleozoic oceans and origin of supercontinent Laurussia as a result of Laurentia and Baltica collision. Information contained within global and regional papers were posted on the maps and the detailed paleoenvironment and plaeolithofacies zones were distinguished within the platforms, basins and ridges.
Artykuł przedstawia szczegółowe mapy paleogeograficzne dla ośmiu przedziałów czasowych w obrębie wczesnego paleozoiku. Czterdzieści map, skonstruowanych przy użyciu programów PLATES i PALEOMAP, zawiera informacje dotyczące tektoniki płyt, paleośrodowiska i paleolitofacji w czasie kambru, ordowiku i syluru. We wczesnym kambrze nastąpił rozpad superkontynentu Pannotia i utworzyły się kontynenty: Gondwana, Laurencja, Bałtyka i Syberia. W późnym kambrze i wczesnym ordowiku w dalszym ciągu ma miejsce spreding oceanów, istnieją też w tym czasie rozległe platformy zalane przez płytkie morza na kontynentach. Reorganizacja płyt litosfery nastąpiła w środkowym ordowiku. Sylur był okresem orogenezy kaledońskiej, zamknięciem wczesno- paleozoicznych oceanów i powstania superkontynentu Laurosji z połączenia Laurencji i Bałtyki. Informacje zawarte w szeregu globalnych i regionalnych prac zostały naniesione na mapy, a w obrębie platform, basenów i grzbietów wydzielono poszczególne strefy paleośrodowiskowe i paleolitofacjalne

Opis:
Presence-absence bivalve species data for each Early Jurassic stage along southeastern South America between 20 and 46°S present-day latitude were processed by a set of analytical methods to analyse the palaeolatitudinal patterns of diversity and distribution. The expected decrease in species diversity towards higher latitudes is punctuated by a consistent local diversity increase between 34 and 42°, especially evident during Pliensbachian and Toarcian times, which may be due to an abrupt change in palaeogeography at that latitude, coinciding with the Curicó direct connection to the open ocean and the establishment of an increased variety of habitats within the extensive Neuquén Basin. The proportions of systematic groups show relative increases towards both higher latitudes (Crassatelloidea, Nuculanoidea, Pectinoidea, Monotoidea, Inoceramoidea) and lower latitudes (Trigonioidea, Pholadomyoidea, Limoidea, Lucinoidea). Epifaunal bivalves were dominant during the Hettangian but by Pliensbachian–Toarcian times they were less common than infaunal ones, while semi-infaunal species had low diversities during the whole Early Jurassic. This study suggests that (a) large scale geographical conditions should be taken into account for the analysis of latitudinal diversity trends among benthonic faunas; and (b) latitudinal trends of some living bivalve lineages may have a longer and more complex history than previously thought.

Opis:
An abundant early Silurian brachiopod assemblage of 14 species, with strong affinities to the early Rhuddanian faunas of Britain and Baltoscandia, was recovered from the Akkerme Peninsula, on the western side of Lake Balkhash, southern Central Kazakstan. The occurrence of Stricklandia lens mullochensis, which is ttre earliest member of the Stricklandia-Costistricklandia lineage, dates this brachiopod assemblage as early Rhuddanian, within a stratigraphic interval from the Akidograptus acuminatus to the lower part of the Monagraptus cyphus graptolite biozones. This is the first well documented record of early Rhuddanian brachiopods in Kazakhstan. The assemblage also includes Meifodia tulkulensis sp. nov. and Eospirifer cinghizicus with well preserved spiralia. The co-occurrence of Stricklandia lens mullochensis and Eospirifer cinghizicus has not been recorded previously and is regarded here as the most signiffcant difference between the early Rhuddanan brachiopod faunas of the Baltic (East-European) Plate and Britain; in contrast Eospirifer first appears in the two latter areas in the late Llandovery.
Opisano obfitą faunę ramienionogową pochodzącą z wczesno-sylurskich warstw odsłoniętych wzdłuż północno-wschodniego wybrzeża półwyspu Akkerme (jez. Bałkasz, Kazachstan). Obecność w zespole Stricklandia lens mullochensis, która jest najwcześniejszym przedstawicielem linii Stricklandia-Costistricklandia, pozwala datować badany zespół na wczesny ruddanian, tj. interwał obejmujący poziomy od Akidograptus acuminatus do Monograptus cyphus. Jest to pierwsze tak dobrze udokumentowane występowanie ramienionogów tego wieku w Kazachstanie. Po raz pierwszy stwierdzono współwystępowanie Stricklandia lens mullochensis i Eospirifer cinghizicus, które zdaniem autorów, stanowi najistotniejszą różnicę między opisywaną fauną a zespołami tego wieku z Platformy Wschodnio-Europejskiej i Wielkiej Brytanii.

Opis:
A charophyte gyrogonite assemblage consisting of Platychara cf. sahnii, Nemegtichara grambastii and Microchara sp. is reported herein from two localities (Bara Simla Hill and Chui Hill sections) of the Lameta Formation at Jabalpur. The Lameta Formation locally underlying the Deccan traps has been shown to be pedogenically modified alluvial plain deposits containing one of the most extensive dinosaur nesting sites in the world. They are associated with dinosaur bones and freshwater ostracod assemblages that suggest a Late Cretaceous (Maastrichtian) age. This is the first detailed systematic account of charophyte gyrogonites from the Lameta Formation. This charophyte assemblage is compatible with the biostratigraphic attribution provided by the ostracods. From a biogeographic viewpoint, it exhibits considerable similarity to other infratrappean assemblages of the Nand, Dongargaon, and Dhamni-Pavna sections (Maharashtra), and some intertrappean assemblages of Kora in Gujarat, Rangapur in Andhra Pradesh and Gurmatkal in South India. Globally, the genus Microchara is well distributed throughout Eurasia, whereas the genus Platychara occurs richly in the Upper Cretaceous deposits of Europe, Asia, America and Africa. However, at the specific level, Platychara cf. sahnii shows close affinities with charophytes from the Maastrichtian of Iran whilst Nemegtichara grambastii shows distinct affinities with two species of Early Palaeogene deposits of China and Mongolia. The presence of charophyte gyrogonites in the Lameta sediments is attributed to local lacustrine and palustrine conditions within a flood plain environment.

Lenses of exotic conglomerates in the Kremna Fm. contain frequent clasts of Mesozoic limestones (e.g. limestones with “filaments” microfacies and Urgonian limestones) and Eocene shallow-water limestones. Fragments of crystalline and volcanic rocks occur subordinately.

Opis:
The Family Kumpanophyllidae Fomichev, 1953, synonymised by Hill (1981) with the Family Aulophyllidae Dybowski, 1873, is emended and accepted as valid. The new concept of this family, based on both new collections and discussion on literature data, confirms the solitary growth form of its type genus Kumpanophyllum Fomichev, 1953. However, several fasciculate colonial taxa, so far assigned to various families, may belong to this family as well. The emended genus Kumpanophyllum forms a widely distributed taxon, present in Eastern and Western Europe and in Asia. Its Serpukhovian and Bashkirian occurrences in China vs Bashkirian occurrences in the Donets Basin and in Spain, may suggest its far-Asiatic origin, but none of the existing taxa can be suggested as ancestral for that genus. Thus, the suborder position of the Kumpanophyllidae remains unknown. Four new species: K. columellatum, K. decessum, K. levis, and K. praecox, three Kumpanophyllum species left in open nomenclature and one offsetting specimen, questionably assigned to the genus, are described.

Opis:
Stratigraphical and sedimentological analyses of Late Neoproterozoic successions in Lesser Himalaya are combined herein with palaeogeographical considerations and comparisons with equivalent successions in India and South China. The succession starts with the Hazara Formation, which contains complete and incomplete Bouma sequences suggesting its deposition in deep marine turbidite settings. The overlying Tanawal Formation, rich in massive sandstone, shale and siltstone, was deposited in shallow marine conditions, as indicated by the presence of parallel lamination, large scale tabular, trough cross- and hummocky cross-stratifications. The Tanawal Formation facies shift laterally from proximal (south-southeast) to distal (north-northwest). The glaciogenic Tanaki Boulder Bed, overlying the Tanawal Formation, was deposited during the Maronian glaciation. It is equivalent to the Blaini Formation of India, and to the Sinian diamictites of South China. The Abbottabad Formation of Cambrian age overlies the Tanaki Boulder Bed, and is composed of dolomite, chert nodules and phosphate-rich packages; similar successions are documented in India and South China at the same stratigraphical interval. The similarities of the Neoproterozoic successions of Lesser Himalaya (both in Pakistan and India) and South China suggests their possible proximity during the break-up of Rodinia and the assembly of the Gondwana Supercontinent.

Opis:
This paper presents classification of the Permian and Triassic paleokarst forms in the Świętokrzyskie Mts, systematic description of the groups of forms and their fillings as well as conclusions concerning environmental conditions of their development. Four groups were distinguished among paleokarst forms developed before the deposition of the Buntsandstein whereas five ones developed during the Buntsandstein deposition (proceeding diachronically) and/or the Middle Triassic time. The Permian-Triassic paleokarst was conditioned by the Variscan tectonic movements and up-lift as well as subsequent formation of the Danish-Polish Trough. The Permian karst developed in the area of mountainous morphology and were often connected with hydrothermal processes. The Triassic karst formed due to tectonic activity stimulating morphological rejuvenation of the region. Wide and low passages representing one of the Triassic paleokarst group presumably formed in fresh and sea waters mixing zone.
Artykuł prezentuje klasyfikację permskich i triasowych form paleokrasowych w Górach Świętokrzyskich, systematyczny opis poszczególnych typów tych form oraz ich wypełnień, jak również wnioski dotyczące warunków ich rozwoju. Wyróżniono cztery typy form pseudokrasowych powstałych przed sedymentacją osadów pstrego piaskowca oraz pięć typów tworzących się w trakcie sedymentacji pstrego piaskowca (następującej diachronicznie) oraz/lub środkowego triasu. Permsko--triasowy kras kopalny był warunkowany waryscyjskimi ruchami tektonicznymi oraz wyniesieniem regionu, a następnie tworzeniem się niecki duńsko-polskiej. Kras permski rozwijał się na obszarze o górskiej rzeźbie i był często związany z procesami hydrotermalnymi. Kras triasowy powstał w rezultacie aktywności tektonicznej powodującej odnowienie rzeźby regionu. Szerokie i niskie kanały reprezentujące jedną z generacji krasu triasowego utworzyły się prawdopodobnie w strefie mieszania się wód słodkich i słonych.
