| 英文摘要 | In recent years, the genesis of highly fractionated Cenozoic Himalayan leucogranite, has attracted much attention because of its good potential for rare -metal mineralization. Field investigations and mineral resource surveys have pointed out that the Himalayan leucogranite belt may become an important strategic mineral reserve base for rare metals in China. At present, the discovered metal assemblages in the belt are dominated by beryllium -niobium -tantalum ( tin -tungsten) assemblage ( such as the Cuonadonglarge tin tungsten -beryllium deposit), but no industrial lithium ore body has been found. The present work reports a newly discovered, superlarge-scale pegmatite -type lithium deposit in the Qongjiagang area of the Higher Himalayan belt, and we revealed the geological characteristics of the first pegmatite -type lithium deposit in the Himalaya. The Qongjiagang pegmatites belong to peraluminous LCTfamily, REL-Li sub -type and albite-spodumene sub -style. The Qongjiagang rare -element pegmatite intruded into marble strata of the Pre -Cambrian Rouqiecun Group as pod -and lense-like bodies, and the ore minerals are mainly spodumene, columbite-group minerals, cassiterite and beryl. The Qongjiagang pegmatites have the internal zonation patterns from rim to core, including saccharoidal albite zone, layered aplite zone and massive microcline + spodumene zone, and the graphic pegmatite zone occurred in the border zone sometimes. Layered aplite zone and massive microcline + spodumene zone hosted a large proportion of spodumene. 44 samples out of 59 analyzed samples have the Li20 contents higher than 0. 80%, with average of 1. 30%. Our resource estimate indicates the Qongjiagang Li deposit is the first pegmatitic lithium deposit with economic value in the Himalayan leucogranite belt, and its discovery confirms good potentials in the findings of large granitic pegmatitic lithium deposit in the Higher Himalayan region of China. |
