Petrogenesis and geochronology of a post-orogenic calc-alkaline magmatic association: the Žulová Pluton, Bohemian Massif

Popis výsledku v původním jazyce

The Žulová Composite Pluton located at the north-eastern margin of the Bohemian Massif exposes undeformed coexisting mafic?felsic association typical of post-orogenic magmatism. The bulk of the pluton is made of biotite granite and granodiorites along with subordinate quartz monzodiorite. New LA-ICP-MS U?Pb zircon dating revealed a synchronous emplacement of the biotite granite (291 ? 5 Ma), granodiorite and quartz monzodiorite (292 ? 4 Ma). The whole-rock geochemistry and the Sr?Nd isotopic data indicate that a plausible source for the biotite granite and the granodiorite could have been a lithologically inhomogeneous pile of Devonian arc-derived, immature metagreywackes interbedded with volcaniclastics. Melting of this crustal material was probably triggered by the rise of hot basic (quartz monzodioritic) magma which could have been an enriched mantle-derived melt contaminated by the underlying Cadomian basement. The Žulová Composite Pluton is a part of a Late Carboniferous?Early Per
