Composition of the cordierite granites of the VBQD and of granites of the VSBG compared with the compositions of possible rock sources. Most of the rock samples display LILE abundance and ratios (Rb/Ba, Rb/Sr, Ba). Also in terms of major elements (K, and and Ca, d), the VBQD and VSBG granites suggest the contribution of partial melting of metapelites and metapsammites during their genesis. Data of the Variscan S-type granites are from Finger & Schiller (2012)
