Fig. 6From: Reassessing the intrusive tempo and magma genesis of the late Variscan Aar batholith: U–Pb geochronology, trace element and initial Hf isotope composition of zirconTrace element data from zircon. A U vs. Th/U; B U/Yb vs. Nb/Y; the mineral vectors in B show the qualitative effect of fractionation of titanite, ilmenite and zircon on U/Yb and Nb/Yb ratios of the remaining melt and later crystallized zircon (after Grimes et al., 2015); C Alpha dose calculations compared to U concentration analyses of representative zircons from the LA-ICP-MS dated populationsBack to article page
