| Abstract: | This paper compile the rare-earth elements and Nd isotope data for lunar pristine rocks from investiga-tions in recent years. Using these data, we compared the REE characteristics of lunar pristine rocks and Nd isotopic compositions of their source regions. Based on the Lunar Magma Ocean model, we then studied their formation and petrogenetic correlations of Mg suite, alkali suite, and KREEP, with especial emphasis on the importance of assimi-lation during early magmatism. And Nd isotopic compositions of mare basalt samples suggest that mantle sources of mare basalts should be heterogeneous, which has not yet been explained by several current models. |
