Permo-Carboniferous and Cretaceous sediments cover the main tectonostratigraphic units of the crystalline basement in NE Bohemia. Within the activities of “Research Centre for Advanced remedial Technologies and Processes” the Czech Geological Survey revises the boreholes and geophysical investigations in the Bohemian Cretaceous Basin and adjacent areas. One part of the research is a compilation of pre-Cretaceous relief of the basement including the crystalline basement and Permo-Carboniferous relief. The digital elevation model uses all boreholes from the Czech Geological Survey-Geofond database, previous geophysical interpretation and the recent surface of the individual geological units defined from detailed geological mapping. The final model reflects well the evolution and recent position of several tectonic blocks and subsequent reprocessing of the information about basement rocks enables compilation of the ´solid´ geological map., Zuzana Skácelová, Bedřich Mlčoch and Zuzana Tasáryová., and Obsahuje bibliografii
Correlation of boreholes and geophysical data provides the framework for 3D modelling of the crystalline basement and the Permo-Carboniferous volcano-sedimentary strata in the Mnichovo Hradiště Basin. The knowledge of depth of the individual interfaces acquired from boreholes database and interpretation of the seismic profiles enabled construction of 3D models. The Stráž crystalline block has bounded the Mnichovo Hradiště Basin on the north, its elongation is in NNW-SSE direction and maximal depth has reached near Sobotka. Its second deepest part known as Mcely or Sukorady sub-basin has been detected southeast of Mladá Boleslav. The negative gravity anomaly in the Mimoň- Český Dub- Turnov- Mnichovo Hradiště area indicated presence of „light“ granitic rocks in the crystalline complex. Moreover, the highest volume of rhyolite ignimbrites with a thickness of up to 180 m is concentrated in Permo-Carboniferous volcano-sedimentary strata in this negative gravity anomaly area, which can be related to a rather deep Late Paleozoic volcanic source (up to a depth of about 10 km)., Zuzana Skácelová, Bedřich Mlčoch and Zuzana Tasáryová., and Obsahuje bibliografii
