摘要
详细叙述了熔流包裹体以及与之密切共生的熔融包裹体和流体包裹体在分布关系、组成相态及其比例、流体成分、硅酸盐熔体分子网络聚合结构以及各种包裹体在加热—淬火—冷冻过程中的热变化行为和均一化温度及其途径等各方面的特征和异同点。认为这种熔流包裹体是在岩浆演化末期从岩浆（熔融体）与水（流体）的不混溶体系中以任意比例同时将其捕获所至，因而，它具有重要的理论意义和实际意义。
The Jianfengling pegmatoid, situated in the upper part of the Jianfengling granite body in Hunan Province, South China, consists mainly of quartz, topaz and zinnwaldite. Three types of inclusions have been found in topaz from the pegmatoid body: (a) silicate melt inclusions, (b) fluid (gas_liquid) inclusions and (c) melt_fluid inclusions. Described here are characteris_ tics of these inclusions as well as their distribution, phase state, composition, molecular textures of the polymerized silicate melt, homogenization temperature and homogenizing behavior during the heating, cooling and quenching processes. It is considered that the melt_fluid inclusions are products of random capturing of the unmixed magma (melt) and liquid (fluid) at the end of magmatic evolution. Therefore, the study of melt_fluid inclusions is of great significan_ ce in the discussion of the magmatic evolution process.
