Extended Data Fig. 2: The Chang’e-6 soil particles used for NanoSIMS analysis.

a, Backscattered electron (BSE) images of three representative Chang’e-6 soil particles (pyroxene, plagioclase and glass), with yellow squares showing the NanoSIMS analysis pits. The other analyzed grains are given in Supplementary Fig. 1. Agglutinate-like material, splash melts, microcraters and adhered tiny particles can be observed on the grain surfaces. b, Raman spectrum of the Chang’e-6 lunar particles. The Raman points were located within the craters produced by the NanoSIMS. Typical peaks of pyroxene and plagioclase are marked in the diagrams. Since olivine grains are rare in soils, these three phases studied in this work are the major components of the Chang’e-6 lunar soils according to the study of physical properties and petrographic characteristics of Chang’e-6 lunar samples26.
