DUCTILE SHEAR BELTS AND TECTONIC DEFORMATION FACIES IN THE NANZHAO AREA,HENAN

The formation and activity of the Moping-Weimosi,Xiapuchi-Guogou and Sandaogang-Xiaoluogou ductile shear belts affected and determined the tectonic deformation of four tec-tonic deformation domains and belts separated by them,thus leading to crustal shortening,fi-nally laying the foundation of the complex tectonic framework and forming four tectonic defor-mation facies,i.e. brittle shear,flexural slope,solid-state rheomorphism and plastic flow or fu-sion.
