    Re-assessment of lithostratigraphy, biostratigraphy, and volcanic activity of the Late Paleozoic Intra-Sudetic, Krkonose-Piedmont and Mnichovo Hradiste basins (Czech Republic) based on new U-Pb CA-ID-TIMS ages

  • Original language description

    5 U-Pb CA-ID-TIMS high-precision (h-p) ages were obtained from single zircon crystals separated from tuffs or ignimbrites embedded in Pennsylvanian to Asselian sediments of the Intra-Sudetic, Krkonose-Piedmont and the adjacent part of the Mnichovo Hradiste basins. The new radioisotopic data are used for extrapolation of ages of dated lithostratigr. units. The existing borehole network in the Late Paleozoic continental basins of centr. and west. Bohemia and in the Sudetic area, and similarity of their stratigraphically equivalent strata including some common lacustrine horizons allow a detailed lithostratigr. correlation between these 2 areas. This in turn, allows combining our new radioisotopic data with similar h-p U-Pb CA-ID-TIMS ages from basins in centr. and west. Bohemia. Result of this correlation is an integrated time-calibrated lithostratigraphical model for the entire Pilsen-Trutnov Basin Complex. This model shows basin-wide alternation of periods of deposition and prevailing non-depostion/erosion due to tectonic events related possibly from accumulation of stress at plate boundaries. Combined data prove the existence of 2 new hiatuses; between (1) Duckmantian and Bolsovian and (2) Cantabrian and Barruelian, which have not been previously recognized from the hiostratigraphic record. Existing macrolloral and faunal data from these basins were used to assign the lithostratigraphic units to particular hiozones and their correlation. In addition, radioisotopic data allowed calibrating these floral as well as terrestrial/fresh-water faunal hiozones and their correlation to global stages and thus contribute to integrated and radioisotopically calibrated marine/non-marine biostratigraphy. 4 periods of increased volcanic activity have been recognised. Radioisotopic ages of volcanic rocks intercalated in sediments of the basin fill correspond with similar ages of intrusive magmatic activity and demonstrate the relationship between plutonic and volcanic processes.
