Multi-element plots using normalization values of McDonough and Sun (1995). (a) Amphibolites. (b) HKCA granitoids (granodiorite-biotite granite and pyroxene monzonite) compared to post collisional gabbros from Cameroon (Kwékam et al., 2013) and representative post collisional high-K igneous rocks from Anatolia (Dilek and Altunkaynak, 2007). (c) Biotite/muscovite leucogranite compared to fractionated Himalaya leucogranites (Liu et al., 2016). (d) Muscovite leucogranites compared to north Nimalaya leucogranites formed after muscovite dehydration melting (type A in Gao et al., 2017).
