The Palaeozoic polyphase tectonothermal record in the Krkonoše-Jizera Crystalline Unit (West Sudetes, Czech Republic).

The succession of Palaeozoic tectonothermal evens was established in the metamorphosed igneous and sedimentary rocks of the Krkonoše-Jizera terrane using Ar-Ar dating on micas. One pre-Variscan and several Variscan groups of ages were determined.
