摘要
The gneissic rocks, which consist mainly of sillimanite-garnet-biotite gneiss, garnet biotite gneiss and staurolite-and kyanite-bearing sillimanite garnet gneiss, are widely distributed in the Diancangshan-Ailaoshan metamorphic complex belt. The results have an important significance for in-depth studying the metamorphic evolution, anatexis and dynamic process of the Diancangshan-Ailaoshan complex belt.
