Fig. 14From: The Val Biandino Intrusive Suite (central Southern Alps, N Italy): new geochronological and geochemical data on the Early Permian magmatic activity in the Southalpine Domain87Sr/86Sri isotopic composition of the VBQD (Thöni et al., 1992) compared with the rocks (metasediments and amphibolites) of the Orobic Variscan basement (Boriani et al., 2003) plotted against SiO2 wt% (a) and 1000/Sr (b), respectively. The 87Sr/86Sr ratio has been recalculated at 290 MaBack to article page
