Figure 7. (a) Plots of the Pitoa granitoids in a molar Al2O3/(MgO + FeOt)–CaO/(MgO + FeOt) diagram [35], with composition fields of partial melts deriving from experimental dehydratation–melting of various source rocks [38]. (b) K/Rb vs. SiO2 diagram showing moderately to strongly evolved character of Pitoa granitoids after [39]
