Sulfur Isotopic Fractionation of the Youngest Chang'e‐5 Basalts: Constraints on the Magma Degassing and Geochemical Features of the Mantle Source

open access: yesGeophysical Research Letters, 2022
The unusually prolonged volcanism at the Chang'e‐5 (CE‐5) landing site remains a mystery. To constrain the geochemical features of the CE‐5 mantle source, we performed in situ sulfur isotope analysis on sulfides of the CE‐5 basalts.
