STUDY ON DEFORMATION AND METAMORPHISM OF JIXIAN—CAMBRIAN IN LUONAN, SHAANXI PROVINCE

By observation on cleavages of mylonites in fault zones in field and optical measurements of metamorpnic minerals in laboratory,it is recognized that three ductile shear napping faults,a ductile shear napping zone,a overturned synclines and a overturned anticline were developed in Jixian Cambrian in Luonan area.The deformation periods are late Caledonian,Variscian,and post Variscian.
