| Abstract: | The cumulative geological data from detailed field mapping and the analyses of protolith formations, metamorphism, deformation and isotopic chronology of granulite facies rocks show that a granulite facies belt of the middle-west part in north China craton is probably recongnised to be an Early Precambrian continent-continent collision orogenic belt. It is due to collage between north China paleo-plate and Iner Mongolian paleo-plate. This belt can be compared to Limpopo belt of well-known Early Precambrian collision belt over the world. |
