Abstract (in english)
   The aim of the project was to throw light upon the development of slow deep creep movements of block type that can be found on slopes of České Středohoří neovolcanities. This was to be done on the basis of detailed analysis of model locality of Čeřeniště Village, Ústí nad Labem district, as well as by analysing other six comparable localities. An interdisciplinary cooperation between engineering geology, geomorphology, Quaternary geology, volcanology, applied geophysics, and dendrochronology was accepted. There is a characteristic feature of the block-type deformation slope relief. Deformations of this type show considerably large platforms, often moderately slanted against the slope. The locality of Čeřeniště Village shows a platform of this type which is 500 m long. Basic trends of movement were detected by field monitoring. The development of Čeřeniště Village slope deformation has to be seen in connection with the Labe River Valley deepening.
   The decisive phase of slope failure obviously originated during eems interglacial when the level of the Labe River appeared up to 16 m lower comparing with present state. Movements have continued from Pleistocene to the present time, while increasing intensity during humid periods of Holocene. It has been proved that rocks of the volcanic complex deformed by deep slope failure are built by six lava flows, at least. the florws are separated by sedimentary intercalations of mostly clayey character which contain a high percentage of smektite, a mineral highly unstable in volume
