The high oxygen fugacity of the Chang’e-5 lunar basalt: Implications for redox stratification of the lunar mantle

Key Points

• High oxygen fugacity indicates altered geochemical processes within lunar basalt, affecting mantle composition.
• The study found that the Chang’e-5 lunar basalt displays an oxygen fugacity comparable to terrestrial rocks.
• Observational analysis of the lunar samples provided insights into the redox stratification of the lunar mantle.
• These findings suggest a complex evolution of the lunar interior, highlighting the importance of lunar geology.
