AI:ISTRACT. - New data on zircon typology and trace element distribution for Baveno-Mottarone and MonlOrfano late-Hercynian plutonic intrusions are reported. Trace element distribution suggests that granitoid rocks, characterized by an overall calc-alkaline affinity, were generated by crystal fractionatiOll processes starting from hybrid melts (
