Extended Data Fig. 3: Mineral chemistry of the CE6 basalt fragments.
From: Ultra-depleted mantle source of basalts from the South Pole–Aitken basin
a, Quadrilateral diagram of pyroxene in the CE6 basalt fragments. Temperature contours63 calculated at 0.5 GPa are shown, where 0.5 GPa was chosen according to the possible pressure range for the low-Ti basalts64. The CE5 samples are plotted (grey region) for comparison. Di, diopside; En, enstatite; Fs, ferrosilite; Hd, hedenbergite. b, Ti# versus Mg# diagram of the pyroxene from CE6 basalt fragments. Fields represent variation in Mg# and Ti# in Apollo very low-Ti, low-Ti, and high-Ti mare basalts65,66. c, Ternary diagram of plagioclase in the CE6 basalt. An, anorthite; Ab, albite; Or, orthoclase. d, Comparison of olivine compositions in CE6 basalts with those within the CE5, Apollo 12 and Apollo 15 basalts23,67. Data are provided in Supplementary Table 3.
