| 英文摘要 | The Himalaya leucogranite belt is evaluated as a prospect for rare -metal mineralization. The Mount Qomolangma is located in the middle part of this leucogranite belt, where a large number of leucogranites and pegmatites occurred as the important components of the Qomolangma orogenic area. Recently, Li -mineralized pegmatites have been recognized and sampled in Hermit Gorge where the light brown red zinnwaldite can be clearly identified in the pegmatite specimens. Further geochemistry and mineralogy study show that these Li mineralized pegmatites have been identified as the elbaite-lepidolite subtype, which are characterized with high contents of rare -metal elements ( Be-Nb-Li), high Rb/Sr ratio, and low Zr/Hf and Nb/Ta ratios. All the mineralogical and geochemical features indicate that these pegmatites have experienced a high degree of magma fractionation. In terms of mineral chemistry, micas have evolved from zinnwaldite to lepidolite, and tourmalines from schorl to elbaite, and the contents of Fe and Mg in them decreased, while the Li content increased, which is indicative of the evolution process of magma. It is the first found Li mineralization in the Qomolangma area, and the striking first report of the occurrence of elbaite-lepidolite subtype pegmatite in Himalaya. Combined with the recent researches of spodumene-petalite subtype pegmatites around Mount Qomolangma ( Pusila, Rachu), the Qomolangma region is probably a crucial Li mineralization prospect in China. |
