2018.4.1 The mafic enclave in charnockite sample KG-13-31 has a different composition in terms of major elements. It is SiO 2 poor (43 wt%) and is also alkaline, with Na 2 O + K 2 O = 2.33 wt% (Fig. 8 a). The enclave is more magnesian than the charnockite with a FeO T /(FeO T + MgO) ratio of 0.61 and has a higher TiO 2 concentration (1.75 wt%).
