【摘要】 本文利用菏泽～长治剖面东段和襄城～章丘剖面中段深地震测深资料进行二维计算与分析解释。结果显示菏泽地区地壳速度结构在横向上、纵向上具有明显的差异。莫氏界面起伏变化大,在菏泽附近其埋深约35km。统计结果显示本区地震多发生在中上地壳,表示它与深地壳结构特征十分密切。更多还原

【Abstract】 In this paper, 2-D calculation and interpretation are carried out respectively by the DSS data of the eastern section of Heze-Changzhi and the middle section of Xiangcheng-Zhangqiu profiles. The results show that the crustal velocity structures are obvionsly differ-ent in lateral and vertical directions in Heze region. The ups and downs of moho are consider-able, and its depth near Heze is about 35 km. Statistical results show that the most of the earthquakes occurred in the middle and upper crust in this region. This indicates that the earthquakes are closely related to the characteristics of the deep crustal structures.更多还原
