| 摘 要： | 挽近时期（新第三纪）以来的构造运动称为新构造运动，是迄今仍在继续活动的构造，往往是具有明显活动特征的活动性断裂带。活动构造的活动性可根据活动断裂、地貌水系、温泉地热、地形变、地震活动、地裂缝等标志鉴定出来。陕西尤其是关中盆地的活动构造十分发育，宏观标志明显，地震活动频繁。

| Abstract: | Neotectonism, the structural movement from Neogene, resulted in the formation of the fault belts with active features. The activities of active structure can be identified by active faults, surface drainage pattern,terrestrial hot spring, topographic deformation, earthquake and geofracture. The active structures are well developed in Shaanxi province, especially in Guanzhong basin,where there are obivious macro-evidence and earthquakes occur frequently. |
