Abstrakty : The studied area of ca. 500 km2 lies within the Main Anticline and the Bytom-Dąbrowa Trough of the Upper Silesia Coal Basin. During the deposition of the fluvial Zabrze Beds, this area was subject to differential subsidence which resulted in gradual eastward thinning of this unit from ca. 250 m near Zabrze to ca. 4 m near Sosnowiec. Maps of net sandstone and coal contents in two stratigraphical intervals selected within the Zabrze Beds point to the presence of four channel tracts. The main tract is parallel to the NE-SW trending axis of maximum subsidence, and the other three are perpendicular to it. During deposition of the Zabrze Beds the main, NE-SW trending channel tract has shifted westward.

Abstrakty : The Markov chains procedure was applied to the study on the sequences of lithofacies and depositional intervals in the Godula Beds (Turonian-Lower Senonian) of the Flysch Carpathians. The model (depositional) and modal (a most frequent in profile) diagrams were constructed and corresponding sequences were recognized. It was found that deposition from high-density turbidity currents of variable retardation rates was the dominating mechanism whereas the low-density turbidity currents were rather rare. The newly deposited sediments were commonly eroded by the succeeding, dense currents. Deposition processes were dominated by the two clearly separated environments: channels and depositional lobes. Their systems were subjected to frequent changes due to lateral migration caused by tectonic movements (uplift of cordilleras and subsidence of sea floor) and eustatic changes of sea level.

Abstrakty : The paper describes scours and crevasse splays formed at the breaks in embankments of the upper Vistula river valley during the summer 1997 flood. The scours cut into the floodplain composed of fining upward channel and overbank deposits. Erosional furrows have developed locally around the scours. In their vicinity, a thin layer of channel-ag gravel was locally laid down. Variously shaped crevasse splays were formed: finger-like, deltoidal and tongue-like. Surface relief, vege-tation and buildings controlled their geometry and sedimentary features. The lower parts of the deposits consist of fine and medium sands with horizontal and low-angle stratification. Higher in the sequences medium and coarse sands with pebbles display planar cross-stratification. Mud balls and black oak trunks redeposited from older alluvia are common. The whole succession represents sheet-flow sediments with partly channelized flow. Locally, at the top, coarse sands, pebbles, mud balls and boulders embedded in silty-sandy matrix occur, representing slurry-flow deposits. Also present were sediments composed of alternating sands and mud pebbles. The vanishing flow phase is marked by occasional ripple marks encountered in the top part of the sequence. Around the flow obstacles (plants, buildings) sand shadows were formed, composed of fine and medium sands with horizontal stratification in the lower parts and ripple cross-lamination along with climbing cross-lamination in the upper parts. The top part included medium and coarse sands with planar cross-stratification. Most of the studied sequences showed coarse-upward grading which is not the effect of changes in the energy of flood waters but originates from the supply of all the time coarser material from the successively deepening scours.

Abstrakty : A new lithostratigraphic unit – the Barnasiówka Radiolarian Shale Formation – is herein defined. It belongs to the Silesian Series of the Outer Carpathians. The formation consists of biosiliceous deposits rich in organic matter, laid down around the Cenomanian-Turonian boundary. The formation includes, from bottom to top: (1) a series of green to black, calcareous and siliceous shales, alternating with layers of chert, siliceous siltstone and sandstone (up to 10 m thick); (2) a series of green to black, argillaceous to siliceous shales, intercalated with tuffites, bentonites, and a ferromanganese layer (up to 9 cm thick) in its middle part (up to 3.2 m thick); (3) a series of green and red, siliceous siltstones and cherts with intercalations of non-calcareous green shales and benthonites (up to 2 m thick). The total thickness of the formation ranges from 0.5 m in the eastern part (reduced tectonically?) up to about 14-15 m in the middle and the western parts of the Silesian Nappe, due to the increase in the number and thickness of turbidite intercalations. The formation represents the Holocryptocanium barbui – Holocryptocanium tuberculatum through the Alie-vium superbum radiolarian zones and the Uvigerinammina praejankoi-Uvigerinammina jankoi foraminiferal zones, which correspond to the Upper Cenomanian through the lowermost Turonian. Microfacies and geochemical characteristics of the distinguished lithological types are presented in this paper, based on recent studies and published data. The described formation has been compared and correlated with deposits of similar age from other tectonic- facies units of the Outer Carpathians in Poland and Ukraine.

Abstrakty : New locality of slope breccias was found in the Western Tatra Mts. It occures in the Długa Valley on a steep slope of ravine beneath the belt of Jurassic radiolarite cliffs. The brecccia consists of angular clasts of radiolarite bound with calcite cements. Void spaces between the clasts contain shells of Holocene snails. The cements are built of columnar crystals composed of acicular subcrystals and of skeletal crystals. The crystals grew rapidly from supersaturated solution due to CO2 degassing. Cementation occurred in vadose conditions in the Atlantcic Phase soon after the scree formation.

Abstrakty : Basing on analysis of tectonic mesostructures, the structural evolution stages of the Gnieździska Syncline have been determined. The structure represents a typical example of folds occurring in the SW margin of the Holy Cross Mountains. The well-exposed syncline displays a wide variety of structures, including: shear and extension joints, stylolites, cleavage, strike-slip and dip-slip faults as well as master joints. Tectonic structures resulting from flexural slip indicate that the Gnieździska Syncline developed as a flexural-slip fold as a result of horizontal NE-SW compression. The subsequent deformation phase included mesostructures pointing to the increasing activity of a nearby Gnieździska-Wola Morawiecka dextral strike-slip fault of regional extent. In the terminal phase of the post-kinematic uplift of the Holy Cross Mountains, T joints and master joints appeared.
