Extended Data Fig. 5: Molar fraction of forsterite in olivine in CE4_0015 and CE4_0016.
From: Chang’E-4 initial spectroscopic identification of lunar far-side mantle-derived materials

The results were derived from VNIS spectra, overlain on calibration lines defined by the relationship between the Fo value and the absorption-band positions of olivine of various compositions (data used to plot the calibration lines are from figure 4 of ref. 37).
