Whole-rock geochemical features of felsic (meta-)igneous rocks from the Sioule region, with (a-b) major element compositions shown in Q-P (Debon and Le Fort, 1988) and A-B (Villaseca et al., 1998) chemical-mineralogical diagrams, (c-e) REE compositions in chondrite-normalized (Palme and O’Neill, 2014) diagrams, and (f) HFSE fractionation degree in the Nb/Ta versus Zr/Hf diagram (Ballouard et al., 2016). For comparison, the composition of early-Variscan cordierite-bearing peraluminous granitoids (CPG) of the Guéret Massif and mid-Variscan trachy-dacitic tuffs and lavas (“Tufs anthracifères” series) occurring west of the Sillon Houiller fault are also shown (Cartannaz, 2006). Abbreviations: (a) to - tonalite, gd - granodiorite, ad - adamellite (monzogranite), gr - granite, qd - quartz diorite, qmzd - quartz monzodiorite, qmz – quartz monzonite, qs - quartz syenite; (b) fp - felsic peraluminous, lp - low peraluminous, mp - moderately peraluminous, hp - highly peraluminous. Samples from this study are shown in bold only when compared to those from the literature.
