For the first time,we describe the recently detected ENE-trending Xingcheng-Taili ductile strike-slip shear zone,which is an important Mesozoic low- to middle-grade deformation tectonic element formed during the reactivation of the North China Craton at the eastern termination of the Yanshanian orogenic belt.Within the Xingcheng-Taili ductile shear zone,the degree of deformation weakens gradually from NW to SE.Three main types of banded granitic gneisses are overprinted as low- to middle grade tectonites.New U-Pb zircon dating gives a wide range of ages.
