青海湟水盆地地壳稳定性的动力学基础
|
摘要
通过对湟水盆地区域震源机制、断层水平运动方式、地层褶皱形态分别反映的现代、第四纪晚期、第三纪构造应力场的对比研究，同时分析1990年以来地震活动图象，得出汉水盆地地壳介质强度可分为三个不同的，为各区未来地震活动强度的预测以及地壳稳定性研究奠定了基础。
The authors comparatively study the focal mechanism . horizontal movement of the fault.stratigraphic fold shapes which reflect the modern' the late Quaternary and Tertiary structural stress field, analyse the seismic active images since 1900, they think that crustal medium magnitude divides into three different regions. And all these investigations lay a foundation to predict earthquakes and study crustal stability in each area.
