China’s graphene find in 2 billion-year-old moon soil defies origin theory
Carbon in lunar samples hints at a moon-based carbon-capturing process, reshaping our understanding of its composition and history.
“The prevalent giant impact theory has been strongly supported by the notion of [a] carbon-depleted moon derived from the early analysis of Apollo samples,” the researchers stated in an unedited manuscript published recently, as reported by South China Morning Post. The team, which included experts from the Shenyang National Laboratory for Materials Science and the China Deep Space Exploration Lab, emphasized that their findings could “reinvent the understanding of chemical components … and the history of the moon.” The structure of the graphene indicates it was formed through “high-temperature processes resulting from volcanic eruptions,” which might have allowed iron-bearing lunar soil to interact with carbon-containing gas molecules in solar winds, leading to mineral catalysis.
