花岗伟晶岩是介于岩浆-热液演化之间的一种岩石类型,是Li、Be等稀有金属矿床的主要赋存岩石。花岗伟晶岩型稀有金属矿床的成矿流体形成机制,即是热液自挥发分饱和岩浆的出溶作用,还是花岗岩浆演化晚期的液态不混溶作用,尚存在很大争议(London,1989;Thomas,2002)。新疆青河县阿斯喀尔特铍矿床同时产有花岗岩型和似花岗伟晶岩型铍矿体。本次研究拟通过流体和熔体包裹体研
Granitic pegmatite is a kind of rock type between magmatic-hydrothermal evolution and is the main pebble rock of Li, Be and other rare metal deposits. The mechanism of ore-forming fluid formation in the granitic pegmatite-type rare-metal deposit, that is, the dissolution of hydrothermal fluids from saturated magmatic lava and the liquid immiscibility of granitic magma in the late evolutionary stage, remains controversial (London, 1989; Thomas, 2002). The Azurite beryllium deposit in Qinghe County, Xinjiang, produced simultaneously granite-type and granite-hosted pegmatite-type beryllium bodies. This study intends to study fluid and melt inclusions
