    AnnotationLate Paleozoic volcanic rocks in the Intra-Sudetic Basin of the Bohemian Massif in the Czech Republic can be subdivided into two series: (I) a minor bimodal trachyandesite-rhyolite series of Upper Carboniferous age with initial 87Sr/86Sr of ca. 0.710 and Nd values of -6.1 also characteristic of volcanics of the near Krkonoše Piedmont Basin (0.707 and -6.0, Ulrych et. al., 2003) and (II) a major differentiated basaltic trachyandesite- trachyandesite-trachyterhyolite series of Lower Permian age with lower initial 87Sr/86Sr of ca. 0.705-0.708 and Nd values ranging from -2.7 to -3.4/-4.1. The mafic rocks represent mantle-melt(s) overprinted by crust during assimilation-fractional crystallization. The Sr-Nd isotopic data confirm a significant crustal component in the volcanic rocks that may have been inherited from the upper mantle source and/or from assimilation of older crust during magmatic underplating and shallow-level melt fractionation.
