Language:

Description:
The aim of the study is to identify the recent local geodynamic processes on the territory of the Dniester PSPP (Ukraine), which arose as a result of the additional man-caused load during the construction of hydro-technical structures. The research is based on the results of 17 cycles of periodic static GNSS campaigns conducted during 2004-2017. In this work the vectors of horizontal displacement of the reference GNSS network points of Dniester PSPP are determined and their scheme is constructed. On the basis of average vectors of horizontal movement velocities during 2004-2017, the value of the velocities of dilatation - the parameter of Earth surface deformation which characterises the relative area expansion or compression, is calculated. As a result of the analysis of velocity distribution of the dilatation of Dniester PSPP territory, the areas of extreme values of compression and stretching are revealed, which testify to the increased geodynamic activity of the pivot part, as well as the main structures of the construction. and Savchyn Ihor, Vaskovets Serhii.

Language:

Description:
The paper studies the connection between the X-ray and thermo quartz luminescence, the massif formation facie features and differentiation of magmatic melt features, using the example of the Permian-Triassic granitoids from the Kolyvan-Tomsk folded belt (KTFB; the Kolyvan, the Barlak, the Ob, and the Novosibirsk rock massifs). The X-ray luminescence optical spectra and the thermoluminescence curves of quartz from the massifs listed above are obtained. The quartz luminescence is proven to be linked to the features of the magmatic melt differentiation. It is shown that the equivalence of the X-ray- and the thermoluminescence of granitoids quartz from different massifs are the result of similar conditions and mechanisms of the granitoids formation with close establishment periods. The obtained data make it possible to consider the KTFB granitoid magmatism as a result of natural magmatic differentiation of the original magma and to use the quartz emission spectra for typing granitoid massifs. The individuality of the Novosibirsk massif quartz, manifested in intense luminescence of Fe 3+, defects of O * (370 nm) and thermoluminescence (TL) at 180-220 °C, can be associated with high fugacity of oxygen, increased temperature and rate of mineral formation in rock collapse mode under tectonically active zone conditions. At the same time, the obtained data provides evidence for the differences in the leucocratic magmatism of the area, allowing differentiation of the Kolyvan-Tomsk folded belt leucogranites into the leucogranites of the Novosibirsk massif (Mo-W type of mineralization) and the leucogranites of the Kolyvan and the Barlak massifs characterized by rare metal mineralization (stannic-tungstic-beryllic with silver). and Boroznovskaya Nina Nikolayevna, Nebera Tatyana Stepanovna.

Language:

Description:
Magnetické pole Země patří mezi fyzikální parametry životního prostředí, stejně jako veličiny meteorologické - teplota, tlak a vlhkost vzduchu, osvětlení, vítr, koncentrace iontů apod. Je tedy na místě uvažovat o tom, že může působit na živé organizmy včetně člověka podobně jako faktory meteorologické, zčásti též nezávisle na aktivitě sluneční. Meteorologické vlivy jsou známy od pradávna. Zkoumání vlivů geomagnetického pole je však mnohem mladšího data. Vždyť přístroje na spojité registrování intenzity geomagnetického pole byly sestrojeny teprve v 70.-80. letech 19. století, číselné vyjádření geomagnetické aktivity pomocí K-indexů se používá od roku 1932 a další metody hodnocení geomagnetické aktivity vznikly ještě později., Jaroslav Střeštík., and Obsahuje seznam literatury

Description:
Obory magnetismu hornin, paleomagnetismu a magnetismu životního prostředí jsou velmi úzce propojeny. Zatímco paleomagnetismus se zabývá vyšetřováním a analýzou remanentních parametrů zafixovaných v horninách a sedimentech jako funkce podmínek jejich vzniku a geologického času, magnetismus hornin vyšetřuje magnetické vlastnosti nositelů remanentního záznamu. Pro dosažení tohoto cíle využívá teorii pevných látek, laboratorních experimentů a numerických simulací různých fyzikálních procesů v těchto minerálech s tzv. uspořádanou magnetickou strukturou. Magnetismus hornin tvoří fyzikální základ paleomagnetismu i relativně nového oboru - magnetismu životního prostředí., Aleš Kapička, Eduard Petrovský., and Obsahuje seznam literatury

Description:
Gravimetrie jako geofyzikální metoda je založena na měření tíhového pole na zemském povrchu. K danému účelu slouží gravimetry, určující hodnotu tíhového zrychlení. Tyto přístroje mají jednoduchý princip, ale vyspělou technologii, která umožňuje registrovat tuto veličinu v řádu 10-8 m.s-2. Této hodnotě se říká mikroGal a je běžně používanou jednotkou při velmi přesných měřeních. Tíhové zrychlení na povrchu Země se pohybuje v rozmezí 978 000 000 až 983 000 000 mikroGal, zatímco mikrogravimetrický průzkum se zabývá anomáliemi 10 až 100 mikroGal. Chyba měření se pohybuje okolo 3-5 mikroGal. S ohledem na fakt, že tíhové zrychlení závisí na zeměpisné šířce (vliv zploštění a rotace Země) a nadmořské výšce (vzdálenost od těžiště Země), zavádějí se příslušné korekce. Rovněž tak je nutno redukovat data a slapové efekty Měsíce a Slunce, vliv morfologie terénu a drift přístroje, závisející na mechanických vlastnostech měřícího systému, environmentálních faktorech (teplota, atmosférický tlak), transportních podmínkách apod., Jan Mrlina., and Obsahuje seznam literatury

Description:
The paper presents the results of fieldwork and geodetic surveys carried out on a landslide in Wleń (Western Sudetes, Izerskie Foothills). This reactivated landslide occured firstly in 2011 and later on 16th July 2016, following heavy rainfall in the Lower Silesia region, and covered an area of ca. 1100 m2 above the renovated “Leśny Dwór” guesthouse in Wleń town. The main scarp of the landslide is built of strongly deformed Upper Permian (Zechstein) heterolithic deposits, composing the marginal part of the Wleń Graben - a NW-SE elongated, tectonic sub-unit within the North Sudetic Synclinorium. The landslide was a consequence of undercutting of steep slopes of the Bóbr River valley by anthropogenic activities and loading of the slope surface by blocks and pedestrian paths in the vicinity of the guesthouse. Monitoring of landslide activity was performed using the initial surface model of the slope subjected to mass movements, LiDAR elevation data, as well as 3D point cloud data from a non-metric camera on an Unmanned Aerial Vehicle (UAV). They were used to construct digital elevation models (DEMs) of the area covered by the landslide. The DEM from photogrammetric UAV data was processed using Structure from Motion (SfM) technology. The obtained dataset was verified by additional measurement series from terrestrial laser scanning (TLS). and Kowalski Aleksander, Wajs Jaroslaw, Kasza Damian.

Language:

Description:
The Moravia territory has been the subject of geokinematic investigation within scope of several realized research projects and repeated GPS campaigns since 1992. The monitoring has been concentrated on all the Moravia region as well as on particular areas of interest concerning the eventual possible geodynamic changes (Králický Sněžník Massif, Diendorf-Čebín Tectonic Zone (DCTZ) and others). At present time all the territory is covered by several tenths of permanent and epoch GNSS stations. Long observation time series at permanent stations alone are not sufficient for delivering the regional velocity field of sufficient density. On the other hand, epoch stations are more densely spread but periods of repeated observations are less frequent and often the data processing is not homogeneous. In the paper the preliminary kinematic model is briefly described which gives for the first time the general view of movement tendencies at the region of Moravia. On base of long-term monitoring it shows that the Southern Moravia region is more active then it was supposed., Lubomil Pospíšil, Otakar Švábenský and Josef Weigel., and Obsahuje bibliografii

Language:

Description:
The GRACE satellites have provided gravity field solutions with approximately monthly resolution since April 2002. The monthly solutions enable investigations of the annual, semi-annual and secular mass variations, which mainly occur in a thin layer of the Earth’s surface. By the end of the GRACE science mission in 2017, the time span has increased to 15 years, making the possibility of determining longer-period variations feasible. First attempts to determine multi-annual variations, i.e. periods of some years but less than 10, are presented in this study. A combination of 3 different PSD estimation methods has been used for identifying the regions of multi-annual mass variations. As a result, 8 different areas have been found with significant multi-annual mass variations. The source of multi-annual mass variations in most detected regions can be identified as related to the ENSO cycle. and Kiss Annamária, Földváry Lóránt.
