| 英文摘要 | Chlorine, an extremely hydrophilic volatile element, provides important information regarding the origin of intrinsic volatiles in the Moon. Lunar apatite was found to have a wider spread of delta Cl-37 (from -1 to +40 parts per thousand versus standard mean ocean chloride) than most terrestrial and chondritic ones (0 +/- 0.5 parts per thousand). However, the provenance of the elevated lunar delta Cl-37 is still enigmatic. Here we report new isotopic data for H and Cl in apatite from three lunar meteorites and discuss possible mechanisms for Cl isotopic fractionation of the Moon. The apatite grain in Dhofar 458 has an average delta Cl-37 value of +76%o, indicative of an extremely heavy Cl reservoir in the Moon. Volatile loss associated with the Moon-forming Giant Impact and the formation of lunar magma ocean could account for the large Cl isotopic fractionation of the Moon. The observed H2O contents (220-5200 ppm), delta D (-100 to +550 parts per thousand) and 8 37 Cl values (+3.8 - +81.1 parts per thousand) in lunar apatite could be understood if late accretion of hydrous components were added to the Moon after the fractionation of Cl isotopes. The heterogeneous distribution of lunar Cl isotopes is probably resulted from complex lunar formation and differentiation processes. |
