Calcium Isotope Fractionation in Plagioclase from Mafic-Ultramafic Rocks: Implications for Magmatic Processes and Planetary Differentiation

Table 1 shows the whole-rock major element compositions of the Panzhihua and Xiaohaizi intrusions; Table 2 presents the calcium isotope compositions of the whole-rock, clinopyroxene, and plagioclase in the two intrusions; Table 3 is the comparison between the calculated calcium isotopic composition of whole rocks and the measured calcium isotopic composition of whole rocks. Table 4 lists the Δ44/40CaPl-cpx values of samples in the two intrusions; Table 5 is the plagioclase-melt calcium fractionation coefficient table estimated at 1000K; Table S1 shows the trace element data of clinopyroxene and plagioclase in the two intrusions; and Tables S2 to S5 respectively present the major element compositions of clinopyroxene and plagioclase in the Panzhihua and Xiaohaizi intrusions.
