英文摘要Recently, the petrogenesis of highly fractionated Himalayan leucogranites has been paid great attention. Moreover, a preliminary study has showed that the Himalayan leucogranites is commonly related to the rare-metal mineralization and warrants future investigation. It is well known that the enrichment of rare-metal elements should be closely related to the magmatic differentiation, which is mainly derived by fractional crystallization. However, relatively little work has focused on the mechanisms and processes of fractional crystallization of the Himalayan leucogranites. In this study, we investigated two typical Himalayan leucogranite plutons, i. e., the Ramba leucogranites within the Tethyan Himalayan belt and the Gaowu leucogranites within the Higher Himalayan belt, which are both characterized by the often presence of rare-metal bearing minerals. According to the comprehensive study on the two plutons including petrography, mineralogy, petrology and whole-rock geochemical composition, we suggest that the fractional crystallization processes of Himalayan leucogranites can be ascribed to two main mechanisms, which are in-situ differentiation and flowage differentiation, respectively. It is noteworthy that most of the Himalayan leucogranites have experienced both of the two processes at different stages during its migration and emplacement.
