    Biotic changes around the radioisotopically constrained Carboniferous-Permian boundary in the Boskovice Basin (Czech Republic)

  • Popis výsledku v původním jazyce

    Presented is an analysis of vegetation patterns across the Carboniferous-Permian boundary in continental setting constrained for the first time in Europe and North America by high-precision U-Pb radioisotopic dating. The analysis is performed on the fossil record of the lloskovice Basin (Czech Republic), a late Palaeozoic half-graben having- 5 km of cumulative thickness. It is dominantly a red bed succession containing numerous grey, mostly lacustrine horizons bearing fairly rich fossil floras and faunas of Late Pennsylvanian to Cisuralian age. U-Pb geochronology on single zircon crystals separated from a volcanic tuff near the top of the Rosice-Oslavany Formation, in the lower part of the basin succession, provided an age of 298.88 0.09 Ma, that nearly exactly corresponds to the Carboniferous-Permian boundary as currently accepted in the International Chronostratigraphic Chart v2016/04. The upper part of the basin fill is correlated via fish faunas with the Intra-Sudetic and Krkonok-Piedmont basins, where embedded volcanic rocks provided late Asselian ages. The succession of the Boskovice Basin records a well-known acidification trend demonstrated by the transition from Gzhelian coal-bearing sediments of the Rosice-Oslavany Formation to Asselian red beds. This trend is interrupted by grey lacustrine horizons, which represent major windows of preservation formed during more humid intervals. Vegetation patterns show the transition from assemblages dominated by free-sporing plants, mostly tree ferns, typical of Late Pennsylvanian wetlands, to peltasperm-walchian conifers dominated assemblages of the Cisuralian. Similar transition has been observed also in coeval succession of the Intra-Sudetic Basin and elsewhere in the former central and western equatorial Pangea.
