Sudetes
Opis:
The Sudetes are a mountain range in Central Europe, which owes its emergence to the Cenozoic rejuvenation of an old Variscan orogen, subject to stresses from the Alps and the Carpathians. The gross morphological features of the Sudetes are typically explained as reflecting the superposition of the effects of long-term, rock-controlled denudation and Late Cenozoic differential uplift and subsidence. In this paper, early conceptual models, developed in the 1950s and 1960s and emphasizing alternating uplift and planation phases, are presented first. A review of more recent work focused on tectonic landforms and geomorphic indicators of tectonic movements follows, with special attention to fault-generated escarpments, valley morphology, stream longitudinal profiles, terraces and fans, drainage basin characteristics and regional geomorphometric studies. Attempts to provide a timeframe of tectonic relief differentiation are also summarized. In the closing part of the paper, the existing approaches and findings are re-evaluated in order to identify challenges and perspectives for future work. The availability of high-resolution digital terrain models creates a unique opportunity to quantify relief features and detect even the subtle topographic signatures of recent tectonics. A need to reconcile the results of geomorphological analysis with those emerging from other studies focused on faults is highlighted.

Opis:
Deposits of the Röt Formation (Lower–Middle Triassic) in the eastern part of the North-Sudetic Synclinorium (Bolesławiec Syncline), SW Poland, include numerous synsedimentary deformation structures. Six boreholes with a total core length of ~434 m enabled macroscopic analysis and description of these deformation structures, supplemented by borehole log interpretation, calcimetric analysis, and interpretation of 2D surface seismics. An interval up to ~42 m-thick at the base of the Röt Formation showed both brittle and soft-sediment deformation structures. Their abundance and intensity decrease towards the top of the Röt Formation, and they completely disappear in the Muschelkalk (Middle Triassic). Both the number of boreholes and their locations indicate the presence of such structures across the entire study area. The occurrence of deformation structures in each borehole analysed and their large lateral range suggest that the uppermost part of the Lower Triassic and lowermost part of the Middle Triassic in the study area were influenced by seismic activity. As a result, tectonic reorganization of the study area is inferred for the latest Early/earliest Middle Triassic.

Opis:
The neo-tectonic research is interested in the study of the movements of Earth’s crust in recent geological times. It could explain the deformation mechanisms that lead to the structuring of drainage catchments. The Morsott-Tebessa-Youkous (Chabro) collapsed basin corresponds to a subsiding depression framed by brittle structures and filled with thick deposits. Our work aims to unveil the neo-tectonic activity and reconstruct the morphometric evolution of the landscape and the drainage network of the basin. For this task, our investigation applies a quantitative analysis of geomorphic indices extracted from the DEM of the study area. We used a GIS-based approach to compile seven morphometric factors namely Integral Hypsometry (HI), the Sinuosity of mountain fronts (Smf), the Valley Floor width to height ratio (VF), the Asymmetry Factor (AF), Basin Shape index (BS), and the topography (T). All these thematic parameters were processed in a Geo-database to calculate the study area’s Relative Tectonic Activity Index (IRAT) as a result. The IRAT map was categorized into three classes. The result highlighted the distribution of relative tectonic activity in the region and unveiled some unknown faults. It associated the sinuosity of rivers and the deformation of the substratum with active tectonic anomalies. This research work succeeded in drawing up a new scheme of the neo-tectonic activity and morphostructural evolution in the collapsed basin.

Opis:
This paper summarizes recent research activities on merging the geodetic, geologic and neotectonic evidence of geodynamics in Croatia. The area of the City of Zagreb, which is the boundary zone of Eastern Alps, Dinnarides and Pannonian Basin is included as well. It is shown here that the evidence for fractures of Eastern Adriatic differs from the previous hypotheses. This conclusion is derived from the results of various geodetic measurements: satellite positioning (GPS), astro-geodetic measurements of deflections of the vertical. These results are combined with geologic measurements and results of seismic activity studies in order to give more detailed and more accurate picture of the current situation in the tectonically very active region of Dinnarides. Several GPS-campaigns performed in the City of Zagreb area are examined as well. Due to the proximity of Croatian capitol, special attention has been paid to the effects of possible hazard on construction code.

Opis:
Coregonid fishes (coregonids) (Salmonidae, Coregoninae) of Siberia show immense morphological and ecological variability, what is reflected in their complex interspecific and intraspecific structure: i.e. occurrence of numerous species, forms and endemic species. Studies of the coregonids of Siberia is crucially important for understanding of their origin, taxonomy and evolution. We have analysed electrophoretically some 13 enzyme systems from over 20 samples of East-Siberian coregonids. This paper was intended as an introduction to a number of primary papers that are planned that will describe the biological and genetic characteristics of studied populations.
