【摘要】 华北地区的现代垂直构造运动基本上沿袭着新构造运动的格局发展,大体上可以划分为鄂尔多斯上升区、汾渭下降带、太行山上升区、渤海下降区、冀豫下降区、冀辽上升区、齐鲁上升区和定县—德州过渡区等八部分。此外还有较小规模的银川下降区、中卫下降区、五原—呼和浩特下降区和下辽河下降区等四部分。 现代水平运动不甚强烈,年应变率为10^-8级。主压应变轴向北50°东左右。南东向的拉张应变占主导地位。更多还原

【Abstract】 The recent vertical movement in North China region inherits generally the development of neotectonic framework. Eight zones in the region can be distinguished, such as Ordos uplift zone, Fen-Wei subsidence zone, Taihangshan uplift zone, Bohai subsidence zone, Heibei-Henan subsidence zone, Hebei-Liaoning uplift zone, Qilu uplift zone and Ding xian-Dezhou transition zone. In addition, some small subsidence zones also exist, such as Yinchuan, Zhongwei, Wuyuan-Hohhot and Xialiaohe subsidence zones.The recent horizontal movement is not intense in this region, annual strain rate is an order of 10^-6. Orientation of principal compression axis is NE 50°, and orientation of principal extention axis is SE predominant. Annual strain value of the latter is more than that of the former.更多还原
