Abstract:Melt inclusions in high-grade metamorphic rocks are melt drops enclosed in host minerals such as garnet and zircon,which are composed of daughter minerals,glass and other accidently trapped solid minerals.In the last decade,melt inclusions have become a new approach to the study of partial melting process in high-grade metamorphic rocks.It is generally difficult to identify and analyze melt inclusions since they are mostly less than 20 tμm in diameter.This paper systematically summarizes the identification methods,microstructural features,and chemical investigation methods.The significance of melt inclusions on the identification of partial melting and constraints of the P-T condition,mechanism and fluid regime of partial melting are also discussed.
