The Ar-Ar ages from the West Sudetes (NE Bohemian Massif): constraints on the Variscan polyphase tectonothermal development.

Popis výsledku v původním jazyce

The polyphase Variscan tectonothermal development of the West Sudetes (NE margin of the Bohemian Massif) was precised by 40Ar/39Ar ages. Late Famennian (359 Ma) mica ages from the high-grade Góry Sowie Block suggest continuous uplift after a Late Devonian HT-LP event contemporaneous with the end of subduction-related HP-LT metamorphism in the East Krkonoše Complex. (Mid-)/Late Devonian HP-events in the Krkonoše-Jizera Terrane and Orlica-ĺnie nik Dome are followed by coeval HT-events between 345 and 335Ma (Visean). The latter are interpreted as consequence of uplift, and decompression during overthrusting of both complexes on their forelands. Subsequent small- to large-scale shear movements dated at around 325-320 Ma (early Namurian) affected the WestSudetes and were accompanied by contemporaneous emplacement of the Krkonoše-Jizera pluton. The upper limit of the tectonometamorphic and magmatic activity is dated at 314-312 Ma (Namurian/Westphalian boundary). The final juxtaposition of
