New breakthroughs in the studies of Himalayan rare -metal mineralization
Wu FuYuan1,2; Wang RuCheng3; Liu XiaoChi1; Xie Lie3
AbstractThe importance of rare -metal mineralization in the Himalayas was never highly thought since it was generally agreed that the widely distributed leucogranites there were generated by in situ partial melting of the Higher Himalayan metamorphic rocks. However, since the advent of highly fractionated model for these leucogranites, the associated rare -metal mineralization had attracted much attention, with discoveries of numerous beryllium-, niobium- and tantalum -bearing deposits. Nevertheless, no significant progress was obtained for the lithium mineral resource in the area. This issue of "Acta Petrologica Sinica" reports discoveries of a super-large Qiongjiagang lithium deposit, Rachu spodumene-bearing pegmatite, and Qianjingou elbaite/lepidolite-bearing pegmatite in the central Himalaya, indicating that the lithium resource in the area is highly expected, and the Himalaya is getting the potential to become a large strategic reserved base for rare -metal mineral resources in China. According to recent studies and progresses, the future works should be focused on the followings: 1) Petrology and geochemistry of the leucogranites, to make clear their fractionation degree and rare -metal mineralization potential; 2) Metamorphic aureole and its fluid metasomatism of the northern Himalayan domes, to look for the hydrothermal metasomatic deposits; 3) Relationship between the movement of the South Tibetan Detachment System ( STDS) and emplacement of the leucogranites, to locate the highly fractionated granites and related mineralized pegmatites. In the near future, a joint research should be carried out to the STDS, mylonized Rouqiecun Group strata and the associated leucogranites in the Pushila area, in order to get a greater breakthrough of lithium resource.
