| 摘 要： | 根据断裂在伸展构造变形中的功能，将渭北地区新生代伸展构造系划分为伸展断层组、传递断层组和滑脱断层组３类。据计算，本区新生代累计水平伸展量约２５～３５ｋｍ，反映出本区横向扩展的势态。３组断层的相互组合构成了伸展构造模式。

| Abstract: | On the basis of the functions of faults in extensional structural deformation,the Cenozoic extensional structural system in the Weibei area,Shaanxi,is classified into the extensional fault set,propagational fault set and detachment fault set.On calculation,the cumulative horizontal extension amount of the study area in the Cenozoic is about 2.5 to 3.5 km,reflecting a situation of lateral extension of the area.The three sets of fault combine to form a model of extensional structure. |
