| 英文摘要 | Present studies have revealed the leucogranites from Himalayan orogen are vital potential for Be-Nb-Ta-Li rare -metal mineralization, and spodumene-bearing pegmatites dominantly concentrated in the Pusi La of the Mount Qomolangma region. In this study, the first spodumene-bearing pegmatite is discovered in the Ra Chu transect, north of the Pusi La. The foliated pegmatites present as lenses concordant with the prominent mylonitic fabric and mainly concentrated in the contact boundary between the calcsilicate of the North Col Formation and the marble in the "Yellow Band" of the Rouqiecun Group. Internal zonation is not observed from the pegmatites. The mineral assemblages of the pegmatite contain Li-Be-Nb ( Ta)-Sn minerals including spodumene, petalite, beryl, columbite and cassiterite. Li20 concentrations of the pegmatite samples from the transect are 1. 30% 2. 15%. Mineralogy and geochemistry results suggest the pegmatites have experienced a high degree of crystal fractionation, which indicates that there is a sufficient prospect for lithium mineralization in the Mount Qomolangma region. The bottom of the "Yellow Band" and top of the North Col Formation corresponding to the high -strain shear zone of the South Tibetan Detachment System is probably the enrichment layer of spodumene-bearing pegmatites and it is an important target zone for lithium mineral exploration in the future. |
