英文摘要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. The modal abundance of sulfides is similar to 0.1 wt%, dominated by troilite with trace cubanite, chalcopyrite and pentlandite, yielding a S-abundance of similar to 360 +/- 180 ppm for the bulk CE-5 basalts. Our analysis shows a decreasing trend of delta S-34 in the magma with crystallization and degassing, suggesting similar to 40% degassing loss of S, and accordingly the maximum S-abundance in CE-5 primitive magma was calibrated to approximately 600 +/- 300 ppm. Considering an extensive fractional crystallization following a low-degree partial melting of the CE-5 basalts, the estimated sulfur abundance in the mantle source is similar to 1-10 ppm. This result suggests a strong depletion of volatiles in the CE-5 mantle source, which may be caused by prolonged magmatic activity.
