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.
