Classification through the modified Q-ANOR diagram (Whalen and Frost, 2013; Fig. 4) shows the wide ADX 10059 of rock types, which range with continuity from quartz diorites and quartz monzodiorites, to tonalites, granodiorites and monzogranites, with minor syenogranites; a well distinct group of leucotonalites, characterised by high Q values, also occur. All rock types are represented by a significant number of SM samples, while BAG- and BMG-like rocks are absent in the CVP. It is worth noting that several samples previously classified as quartz diorites fall in the quartz monzodiorite field in the Q\'-ANOR diagram, as a result of their high biotite modal contents, shifting the compositions to higher Or normative values. The same occurs for many CVP biotite tonalite samples, which plot in the granodiorite field. The use of the granite mesonorm (Mielke and Winkler, 1979), designed to account for biotite and amphibole normative amounts, does not provide an improved Q\'-ANOR classification. On the contrary in the obtained diagram (not shown), quartz diorites are totally lacking and BAG classify as tonalites, in contrast with the modal compositions of the rocks. Moreover, the results obtained with the CIPW values are more consistent with those obtained by using other widely used geochemical classifications (e.g., De la Roche et al., 1980 and Middlemost, 1994; not shown).
