Variscan polyphase tectonothermal record in the West Sudetes (Bohemian Massif)- deduced from Ar-Ar- ages.

Abstract

The succession of Palaeozoic tectonothermal events is recorded in the metamorphosed igneous and sedimentary rocks of the W-Sudetic terranes. New population and single grain 40Ar-39Ar data precise the sequence of the prominent Variscan events.
