摘要
癞子岭黄玉云英岩矿物中流体-熔融包裹体研究揭示黄玉云英岩是岩浆-热液过渡阶段的结晶产物。而黄玉云英岩中岩浆作用与交代作用特征并存现象则是低温成岩熔体在结晶过程中共存的热液对已形成的矿物产生水岩反应的结果。
It is found that topaz greisen in the Laiziling granite in Hunan Province is possessive of bothcharacteristics of magmatism and signs of metasomatism. Its genesis has long been a controversialissue. lnclusion studies of mlnerals from the topaz greisen (especially fluid-melt inclusions) indi-cates that the topaz grelsen crystallized during the magmatic-hydrothermal transitional stage ofmagma evolution. The co-occurrence of magmatism and metasomatism resulted from water/rockreaction between hydrothermal solutions and crystallized minerals during the process of crystal-lization of low temperature rock forming melt.
