摘要

月球园艺导致挥发性动员和稳定的同位素分馏，这些分馏依赖于质量。质量无关分馏(MIF)的明确作用，如光化学产生的分馏，尚未在月球上得到证实。我们在月球土壤75081、690中观测到了硫同位素的MIF，而在土壤74241、204中没有观测到MIF。MIF可能是在土壤成熟过程中硫挥发后产生的。75081、690和74241、204之间的同位素差异可能反映了光化学的差异，如光照或光化学活性挥发性硫的产生，例如，由于太阳风注入的H含量不同。

Isotopic evidence of sulfur photochemistry during lunar regolith formation

Lunar gardening results in volatile mobilisation and stable isotopic fractionations that are mass dependent. An unambiguous role for mass independent fractionation (MIF), such as that produced by photochemistry, has not been demonstrated on the Moon. We observe MIF for sulfur isotopes in lunar soil 75081, 690 while MIF is not observed in soil 74241, 204. The MIF is likely generated after sulfur is volatilised during soil maturation processes. The isotopic discrepancy between 75081, 690 and 74241, 204 may reflect differences in photochemistry, such as illumination or in generation of photochemically active volatile sulfur species, for instance, due to varying H contents from solar wind implantation.
