| Abstrakt: | Abstract: 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). |
