Depositional architectures, stratigraphy, and depositional regime of Lower-Middle Turonian sandstone bodies, northwestern part of the Bohemian Cretaceous Basin
Skopcová, Monika ; Uličný, David (advisor) ; Čech, Stanislav (referee)
Sandstone bodies of the Lower and Middle Turonian well exposed in the northwestern part of the Bohemian Cretaceous Basin represent deposits of the coarse-grained deltas. Aim of this paper is to interpret the architectures, stratigraphy and depositional regime of these bodies. The main architectural elements are clinoforms which show intermediate dip 4ř to 5ř of the delta slope and the direction of the progradation of the delta to the west-southwest. Correlation of the lithological profiles with the well - log data provided the stratigraphic classification of the outcrops in the studied area mostly to the genetic sequence TUR2. Correlations in one of the two stratigraphic cross - sections revealed the existence of the second delta body prograding into the basin from Most - Teplice Palaeohigh during TUR1. Detailed study of the sedimentary structures in the outcrops show high degree of reworking of foresets by tidal generated current. Two main directions of the paleocurrents results from the analysis - dominant current to the NW and subordinate current to the SE - SSE.

Projekt SLICE má za úkol zkoumat hlubinnou stavbu středoevropské oblasti a jeho cílem je přispět k výzkumu stavby zemské kůry a svrchního pláště v oblasti Českého masivu a jeho styku se sousedními tektonickými jednotkami. Pro studium hlubinné stavby je využívána seismická refrakční metoda, kdy se registrují seismické vlny generované uměle vyvolanými odpaly a posléze je zjišťována rychlost šíření seismických vln v různých hloubkách. Tyto údaje pak zprostředkovaně poskytnou informace o strukturních vlastnostech měřeného prostředí až do oblasti svrchního pláště. Je popsáno propojení refrakčních experimentů ALP 2002 a SUDETES 2003 na našem území.
New achievements in sedimentary geology of the western part of the Bohemian Cretaceous Basin
Uličný, David ; Laurin, Jiří
Since the Late Cenomanian time the shallow seaway of the Bohemian Cretaceous Basin facilitated water-mass transfer across the nortehn part of the Bohemian massif. Marine currents flowing along the seawaz axis strongly influenced the deltaic deposition at basin margins. We interpret the narrowing of the seaway between the Czech and Saxonian parts of the basin as the main cause of vigorous tidal circulation. Acceleration of tidal currents in this region is reproduced also by numerical modelling of tidal circulation performed at the Imperial College (London) on the basis of our data.
