     Located in the west part of northern margin of North China Block（NCB）,the study area is the key part to interpret tectonic evolution of Central Asian Orogenic Belt. Based on the field geological investigation, it is TIMS Zircon U-Pb technology employed to analyze chronology of intrusive rock, we concluded that there should be craton crystalline basement （Neoarchean,2 619±18Ma,2 563±21Ma） in the study region. It experienced the strong collision orogeny in late Paleo-proterozoic （2.0Ga） and the metamorphic event of 1.9 Ga, which caused the intrusion of granitic and diorite mass, following with other three important large-scale tectonic stages i.e. Mesoproterozoic stretching cracking, Carboniferous oceanic crust subduction and Triassic-Permian collision split.
