Chemical composition of the main mineral phases of the Bini lavas and hosted spinel lherzolites: (a) representative feldspars in the ternary An–Ab–Or diagram of Smith and Brown (1988); (b) Analyzed clinopyroxenes in the ternary Wo–En–Fs diagram of Morimoto et al. (1988); (c) Ti–Fe oxides in the ternary Fe₂O₃–Al₂O₃–Cr₂O₃ diagram of Stevens (1944); (d) Spinels Cr# versus Mg# diagram, the refractory and fertile peridotite fields are from Bian et al. (2024). Some data of feldspars and pyroxenes from Tiabou et al. (2019) were also used for these diagrams (in black color). For mineral symbols: Ab, albite; An, anorthite; Sa, sanidine; Or, orthoclase; En, enstatite; Di, diopside; Fs, ferrosilite; Wo, wollastonite; Hd, hedenbergite; Sp, spinel.
