ABSTRACT: The Meta-Carpathian Arch, that comprised cratonic areas of SE Poland, usually experienced in the Mesozoic much less subsidence, or showed uplift, with regard to the Polish part of the Central European Basin situated farther north. In marked contrast, the areas of the Meta-Carpathian Arch were affected by strong subsidence in Middle and Late Jurassic time, and the peri-Carpathian segment of the Polish Rift began to develop in the Middle Jurassic as a southern extension of that rift, the existence of which north of the Holy Cross Lineament dates back to the Triassic or Permian. A stronger attenuation of continental crust can be recognized south of the Holy Cross Transfer Fault, which bounded the peri-Carpathian segment to the north; this is a feature consistent with the extension of the Polish Rift into the domain of the Carpathian Tethys. The Jurassic tectonic events controlled in the studied areas the formation of the three transgressive -regressive tectono-stratigraphic units: the COK Sequence (Callovian, Oxfordian and Lower Kimmeridgian, upper boundary near the top of the Hypselocyclum Zone); the LUK Sequence (Lower and Upper Kimmeridgian, upper boundary within the Eudoxus Zone); and the KVB Sequence (topmost Kimmeridgian, Volgian and Lower Berriasian). Coeval tectonic events, corresponding to those recorded in cratonic Poland, can be recognized in different parts of Europe, particularly in the Carpathians. The alternating phases of relative uplift and subsidence, experienced by the areas of the Meta-Carpathian Arch that flanked the Central European Basin on the south, can be attributed to fluctuations of intraplate stresses. The peculiar behaviour of the Cracow region in Mesozoic and Miocene time, as an area never affected by strong subsidence, is thought to have resulted from the presence of Variscan granitoids at its depths. A development of the Polish Rift Basin in agreement with models assuming simple shear on lithospheric scale is suggested.

Late Middle Jurassic to earliest Cretaceous stratigraphy and microfacies of the Czorsztyn Succession in the Spisz area, Pieniny Klippen Belt, Poland

ABSTRACT: A stratigraphic and microfacies study of the pelagic carbonate sequence of late Middle Jurassic to earliest Cretaceous age of the Czorsztyn Succession in the Spisz area of the Pieniny Klippen Belt is presented. The sequence begins with the Czorsztyn Limestone Formation which developed on subsiding blocks of shallow-water crinoid limestones during the time interval from the Bathonian to Early/Middle Tithonian. The three succeeding microfacies are recognized and dated: the filament microfacies (Bathonian-Callovian, and ?earliest Oxfordian), the Globuligerina microfacies (Oxfordian), the Saccocoma microfacies (Kimmeridgian to Early/Middle Tithonian). The still younger microfacies of the Dursztyn Limestone Formation include the Globochaete microfacies, and calpionellid microfacies of Middle/Late Tithonian to Middle Berriasian age. The organogenic limestones and breccias of the Lysa Limestone Formation are of Late Berriasian age; their origin was related to tectonic activity which produced a highly diversified sea bottom topography markedly changing the previous sedimentation pattern. The lowermost part of the Spisz Limestone Formation is extremely condensed, and corresponds to a large part of the Valanginian, excluding its uppermost part. The most important new findings of Valanginian ammonites include representatives of genera: Thurmanniceras, Karakaschiceras, Olcostephanus, and Jeanthieuloyites.

The topmost Cretaceous disciniscan brachiopods, Discinisca (Arquinisca subgen.n.) vistulae sp.n., from the Middle Vistula Valley, Central Poland
RADWANSKA, U. & RADWANSKI, A.
Institute of Geology,University of Warsaw, Al. Zwirki i Wigury 93, 02-089 Warszawa, Poland
ABSTRACT: A new taxon of inarticulate brachiopods, Discinisca (Arquinisca subgen.n.) vistulae sp.n., is established to characterize the specimens of latest Cretaceous age (topmost Maastrichtian: Tenuipteria argentea Zone = Belemnella kazimiroviensis Zone), and coming from the Nasilow section, Middle Vistula Valley, Central Poland. This new taxon of the genus Discinisca DALL, 1871, is the first recognized specifically within the Cretaceous System, and is regarded to represent a separate subgenus, to embrace the disciniscans featured by their dorsal valves elongated, dome-shaped, and laterally flapped. The appearance of the disciniscan brachiopods within the topmost Cretaceous sequence of the Middle Vistula Valley was convergent with the decline of the Late Cretaceous regressive cycle when extremely shallow-marine areas had evolved to yield environmental conditions the most compatible with life requirements of the present-day representatives of that extant genus. This is thought to have involved a rapid phyletic diversification of the genus Discinisca, and its world-wide distribution during the Tertiary.

Early Paleocene crabs (Crustacea, Decapoda) from the Middle Vistula Valley, Central Poland
FRAAYE, R.H.B.
Geo Centrum Brabant, St. Lambertusweg 4, 5291 NB Boxtel, The Netherlands
ABSTRACT: For the first time decapod crustaceans are recorded from the Danian of Nasilow, Middle Vistula Valley, Central Poland. The presence of the species Necrocarcinus senonensis SCHLÜTER, 1868, and the genus Titanocarcinus extends the known paleogeographic distribution of these taxa. A possible phylogeny of the genus Necrocarcinus BELL, 1863, is discussed.

Arthropod trackways, "Diplichnites" triassicus (LINCK, 1943), from the Lower Triassic (Buntsandstein) fluvial deposits of the Holy Cross Mts, Central Poland

ABSTRACT: Arthropod trackways of possibly notostracan origin, determined as "Diplichnites" triassicus (LINCK, 1943), are described from the Buntsandstein (Lower Triassic) fluvial deposits exposed at Stryczowice on the north-eastern margin of the Holy Cross Mountains, Central Poland. These trackways form an almost monotypic ichnocoenose preserved on the sole surfaces of sandstone beds, interpreted as crevasse-splay deposits. In contrast to other "Diplichnites" triassicus ichnocoenoses, the trackways have been left by animals moving generally down-current.

Maastrichtian ammonites and biostratigraphy of the Sakhalin and the Shikotan Islands, Far Eastern Russia
YAZIKOVA, E. A.

ABSTRACT: Stratigraphy, ammonite paleontology, and regional characteristics are presented from the Maastrichtian deposits of the Sakhalin and the Shikotan Islands, Far Eastern Russia. Two different ammonite biostratigraphic zonal schemes based on the representatives of the family Desmocerataceae and the Tetragonitaceae, respectively, are established and their correlation with the Japanese ammonite zonation is suggested. All ammonites are monographed, and of the recognized 17 species, part is reported for the first time from the Maastrichtian of the studied area, the Kamchatka Peninsula including.
