Late Devonian to Early Carboniferous Bimodal Volcanic Rocks of the Ještěd Range Unit (W Sudetes): Constraints on the Development of the Variscan Orogenic Wedge.

Popis výsledku v původním jazyce

Late Palaeozoic volcanism characterize the Ještěd Range Unit (JRU) forming the westernmost margin of the Krkonoše-Jizera terrane (KJT) and the lowermost part of the W- to NW-directed KJT orogenic wedge (W Sudetes). The Late Palaeozoic metavolcanics of the JRU Middle/Late Devonian to Early Carboniferous sequence are represented by metarhyolite bodies, submarine basic amygdaloidal lavas and sills (&#61617; dykes) of doleritic basalts. Regarding the geochmical features, porphyroids may be compared with within-plate felsic igneous rocks. Basaltic rocks of WPB-like composition were protolith of the JRU metabasites. The primary magmas were produced by limited melting in the upwelling astenosphere associated with extension of continental lithosphere. Prior the regional metamorphism, the porphyroids were high-silica rhyolites, and may be co-genetic with the basaltic rocks by prolonged fractionation of common mantle-derived melt. The JRU Late Palaeozoic volcanism started in the latest Middle De
