Fig. 2: Chemical composition of olivine and clinopyroxene from Chang’e-5 basalt clasts.
From: Surges in volcanic activity on the Moon about two billion years ago
a Electron microprobe Fo (mol%) traverses for Group 1 olivine from core to rim. b A reverse profile for Group 2 olivine. c Electron microprobe Mg# [defined as 100 × Mg/(Mg + Fe), mole fraction] traverses for clinopyroxene from core to rim. EMPA traverses are marked in Supplementary Figs. 1–6, and data are provided in Supplementary Data 1–2. Abbreviations: Fo forsterite.
