【摘要】 本文将珠海地貌划分为4种类型,分析其地貌发育和北东向、北西向、北东东向等多组断裂构造的关系。根据海岸地貌特征,现代地形变化和新构造运动年代学所估算的构造运动的速率表明,珠海地壳稳定性较好,地震危险性较小。更多还原

【Abstract】 In the thesis,landforms in Zhouhai are divided into 4 types and the relationship be- tween the geomorphologic development and the fault structure,individually belonging to NE,NW,and NNE groups is analysed. Based on the characters of coastal landorms,the changes of modern relief and the rate of the crustal movement calculated from neo-tectonic chronology,it is thought that the crust in Zhouhai is stable and the potential disaster caused by earthquake seems weak.更多还原
