摘要: 本文主要通过野外对断裂带糜棱岩、劈理的观测和室内对变质矿物的光学测定,确定洛南地区蓟县系冯家湾组—寒武系发育三条韧性剪切推覆新层,一条韧性剪切推覆带,一个倒转向斜和一个倒转背科,变形期为晚加里东期,华力西期、后华力西期。Abstract: 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.
