Keywords: crack gauge, active fault, displacements;
During last five years, an extensomtric net using TM71 gauges was being founded in the Western Slovakia part. There was selected some significant fault structures to measure microdisplacements connected with active fault movements as well as effects related to recent earthquake activity. Due to effort of annual climatic dialatational effects elimination, we suggested installation of the gauges under surface in local karst caves. There were selected seven caves (Slopy C., Zbojnícka C., C. Sedmička, Plavecká C., Driny C., Čachická C., Beckovská C.) and two surface fault outcrops (Plavecké Podhradie – Dobrá Voda fault and Smolenice fault). Most of the sites are localised at active fautl structures, what reflects e.g. by tufas occurence, higher cave air temperature or shear cracks crossing cave sinter decoration.
The current results show remarkable displacements trends of tenths or hundreths mm per year as well as horizontal strike-slip sences. Faults with orientation close to NW–SE direction tend to have dextral strike-slip movements sence, and faults of NE–SW or N–S directions tend to move in sinistral strike-slip sence. These fault displacements results are in full agreements with current and prior geological conceptions in the area. On the other hand, during aerthquakes the displacements sences can be changed due to stress relaxation in fault zones too. Moreover, here was registered a displacements acceleration during tremor events and the displacements were registered before the earthquakes as well.
Stará jímka – fossil record in the sediments of the Late Glacial

Keywords:palynology, Late Glacial, geological mapping;
Geological, geomorphological and palaeoecological study of Quaternary sediments was conducted in connection with the geological mapping of the map sheet 22-333 Srní at a scale of 1:25,000 (Babůrek, et al., 2006). The Stará Jímka (former lake) is near Prášily village, below the east slope of the PoledníkMt. (1315 m a.s.l.). The Stará Jímka area lies approximately 1500 m to the north of thePrášilskéJezeroLake. Both localities belong to the same basin of the Jezerní Potok stream. The organic sediments were analysed on the pollen analyses and palaeoalgology. The peatbog sediments on the map sheet Srní (22-333) are the subject of palynological investigation and Quaternary – geological mapping. Several samples of the localities (StaráJímkaLake – Pod Poledníkem) were taken to be radiocarbondated (GliwiceRadiocarbonLaboratorySilesianUniversity of Technology, Gliwice, Poland). Results of pollen analysis are used for the reconstruction of vegetational evolution in the Bohemian/Bavarian Forest. The important and interesting sediments of the glacial lakeStará Jímka have been found near the Prášilské Jezero lake. They were used for the new interpretation in relation to the geological setting of the area. Lake deposits and peat-bog sediments contained palynological and palaeoalgological assemblages. These assemblages indicate the Late Glacial (15,000–10,250 BP) and the Holocene (10,250 BP – recent).
The palynological research was supported by the grant (research program) MZP000257801 (Czech Republic).

Role of short-lasting downpours in the shaping processes in the slopes and bottoms of valleys in the GorceMountains (exemplified by Jaszcze and Jamne river valleys)

Key words: mass movements, heavy downpours, GorceMountains;
During extreme rainfalls the greatest transformation of the mountain relief is taking place. Heavy downpours and floods are accelerating denudationof slopes as well as erosion and the accumulation in the bottoms of valleys(Słupik, 1981, Starkel, 1996, Gil, 1998).Their geomorphological effect depends not only on the amount and duration ofrainfalls, but alsoon their intensity and the spatial extent.Intensity of mass movements and floods dependalso onthe relief, type and thickness of soil, a lithology and a tectonic of rocks,which determine the infiltration rate and the runoff. Important role in mass movement triggering play also human activity (land use, terracing, undercutting of slopes).
The aim of study is pay attention on therole of short-lasting downpours in July 1997 and 2008 in shaping of Jaszcze and Jamne valleys in the GorceMountains.
The narrow valley of Jaszcze with very steep slopes iscovered by dense forestpatches. On the contrary JamneValleywithpredominate gentle slopes ismainlydeforested.
In higher elevations of the Jaszcze catchment part meadows and pastures are prevail, in lower an arable land is dominating. In contrast, Jamne catchment beside meadows and pasturesan arable fieldare reaching up to 1100 m a.s.l. (Obrębska-Starklowa, 1970).
On the basis of analysis of air photos,after rainfalls in July 1997, 85 new shallows landslides were registered (55 inJaszcze valley and 30 in the Jamne valley) about the total area of 29,700 m2. Among forms dominated slumps and mudflows ofloamy-sandy regolith,created mainly on grass covered steep slopes(≥20º), on edges of field terraces and on colluvium of old landslides.
The flood on 23 July 2008 was also connected with heavy downpours, when daily rainfallreached 76.3 mm at meteorological station in Ochotnica Górna. The highest water level in Jaszcze and Jamne streamswas noted about17:00 h.The largest changes took place in the Jamne channel,due to lower of forest cover and higher density of river network incomparison to theJaszcze catchment. Lateral erosion dominated above downcutting, caused reactivationof old undercuts and developing of new ones, the height reaching up to 5 m. The boulders up to 25 cm size were transported and the deposition of debris followed. Older gravel bars were cut and new ones were build up.Only few small earth slumps appeared on the slopes. Such forms in the forest were not observed.

Key words: geomorphological map;
The last general geomorphological map of the Czech Republic in the scale 1:500,000 edited by Otakar Stehlík was published in 1965 as an addition to the book of fellow workers of the Institute of Geography, Czechoslovak Academy of Sciences in Brno “Geomorphology of Czech Lands”. For the prepared Landscape Atlas of the Czech Republic, a group of geomorphologists composed by B. Balatka (Charles University of Prague), T. Pánek (University of Ostrava), K. Kirchner (Institute of Geonics, Academy of Sciences of the Czech Republic, v.v.i. Branch Brno) and J. Demek, P. Mackovčin and P. Slavík (The Silva Tarouca Research Institute for Landscape and Ornamental Gardening, v.v.i. Průhonice) prepared a new general geomorphological map of the country. In agreement with recent trends in general geomorphology and geomorphological mapping and in relation to the final map scale 1:500,000, the basic mapped units are (meso) landforms classified along their appearance (shape-mainly slope inclination and elevation), genesis and age. Authors had used as the topographic base modified digital vectorizedmap in the scale 1:500,000 ArcČR 500 of the firm ARCDATA Praha s.r.o. Author also had usedcontoursand elevations for the visualizationand location oflandforms. Slopes in the map are divided according their inclination into groups (0–2°, 2–5°, 5–15° and 15 and more degrees). Authors had used for division of landforms according their origin recommendations of IGU Commission for geomorphological research and mapping and formed groups of tectonic landforms, Neovolcanic landforms, polygenetic erosional landforms, fluvial erosional landforms,karst and pseudokarst landforms,gravitational erosional landforms, glacial erosional landforms,fluvial accumulation landforms,gravitationaccumulation landforms, glacial and fluvioglacial accumulation landforms, aeolian accumulation landforms, organic landforms and anthropogenic landforms. Origin of landforms is in the map shown by colors. Digital elaboration of the map in the GIS milieu using software of the firm ESRI ArcGIS 9.2 ran in the Department of GIS application of VÚKOZ in Brno and in the firm ESPRIT in Banska Štiavnica (Slovakia). Landforms have been shown by color areas, linear and point signs. The basic principle of the visualization is that more inclined landforms are shown by darker shade of colors than less inclined landforms.The new geomorphological maps shows, that the relief of the Bohemian massif and the Moravian–Silesian terrane is the result of three types of Neotectonic processes – folding (mega folding), fault-folding and block movements. At the same time it is clear, that the west-European platform in the collision zone of the Gondwana and Laurussia does not reacted on neotectonic processes as the whole, but the response in individual parts was individual and different. In the map are shown megaanticlinals and megasynclinals.For the first time are shown various types of planation surfaces in the scale 1:500,000. Especially pediments and cryopediments were not mapped on the whole territory in this scale up to now. The map has also shown the large extent of cryogenic modelation in the cold periods of Pleistocene in the conditions of permafrost. The authors used the map of the Quaternary rocks (P. Havlíček, O. Holásek, M. Růžička, J. Tyráček) from the Landscape Atlas for the visualization of fluvial accumulation landforms.

Key words: mountain glaciation, pollen analysis, Late Glacial, Holocene, KrkonošeMts.;
Sedimentary core from the cirque of Labský důl valley (1039 m a.s.l.) in the KrkonošeMountains reflects the environmental history since about 30,000 years ago. The analyse of magnetic susceptibility, carbon content, pollen assemblages and macrofossil data in a15 m thick sediment sequence provide the first continuous record of Lateglacial and Holocene vegetation history in Sudetes region of the Czech Republic. The succession of sedimentary units in the lower part of the core suggests that the cirque was ice-free before the onset of the last glaciation at the beginning of MIS 2. Highly variable climate prevailed during this period with cold conditions culminating about 17,000 cal. BP. Cold climate persisted until the Lateglacial period which is evidenced by identified warming and cooling events correlated with the Allerod and the Younger Dryas periods. Sparse, treeless vegetation dominated in the catchment area at that time. The sequence of interrupted thinly laminated silts reflects the retreat and temporary readvance of local glacier in the cirque during 12,500–10,800 cal. BP. Since this period, the alpine treeline ecotone gradually shifted above the cirque floor. Palaeoclimatic conditions in the early Holocene fluctuated strongly, whereas since 5100 cal. BP had been more stable. The pollen-based climate reconstructions suggest significant cooling at around 9800–9300, 7700–7300 and 4000–3300 cal. BP. Spruce forests have dominated the site since 5000 cal. BP when the vegetation became similar to the modern one.
