| 摘 要： | 本文以重磁资料为基础,研究了龙门山地区的深部构造与地震活动的关系。认为:①龙门山推覆构造带可分成泸定——灌县,灌县——北川,北川——广元三大段;②在龙门山推覆构造带西侧沿小金、迭溪、平武一线存在隐伏推覆,是未来中强地震活动的主要场所。

| Abstract: | Based on the data of gravity anomaly and acromagnetic anomaly, the deep structure and its relation to earthquake activity are discussed in this paper. It is believed that the Longmenshan nappe structure belt is consisted of three sections (Luding-Guanxian, Guanxian-Beichuan and Beichuan-Guangyuan), and a concealed nappe structure is existed along the line of Xiaojing, Diexi and Songpan in the western area of Longmenshan mountain, where the moderate earthquakes would frequently occur in future. |
