Plots related to the chemistry of clinopyroxene crystals in Sung Valley ijolites. a Triangular Na-Mg-Fe classification diagram showing that all points of mineral chemistry of clinopyroxene fall in the area diopside and aegirine-augite. This figure also shows the comparison of clinopyroxene from ijolites in Sung Valley UACC with clinopyroxene from Kerimasi and Fen complex ijolites. b Q–J classification diagram for the pyroxenes (Morimoto et al., 1988) showing that all the points of clinopyroxene (aegirine-augite and diopside) composition fall into the Quad field. c Scatter plot between Mg# and Ti in Clinopyroxene showing the depletion of Ti along the line of fractionation of Clinopyroxene
