摘要
A set of rock assemblage (Kyanite garnet quartzfeldspathic gneiss assemblage), composed of kyanite garnet quartzfeldspathic gneiss, graphite kyanite garnet quartzfeldspathic gneiss, graphite garnet felsic gneiss and graphite kyanite garnet quartzite was discovered in high-grade metamorphic complex in west Ulanbulang area, located at Yinshan block, western block, North China Craton during the recently 1∶ 50 000 geological mapping. It is also lowered in total REE and relatively depleted in light REE. The textures and components of two groups detrital zircon respectively 2 461~2 542 Ma and 2 349~2 399 Ma in the rocks show that they are not only from igneous rock source area but also from metamorphic source area.
