| 英文摘要 | In this paper, we analyzed the aeromagnetic anomaly data in the Longmenshan mountains and adjacent areas by different methods, such as vertical magnetization, horizontal and vertical derivation, upward continuation, frequency and wavelet transform. The results show that the characteristics of magnetic anomalies suggest this area could be divided into three magnetic anomaly blocks which have different medium properties in crust. They are the Songpan-Garze magnetic anomaly area, the Longmenshan negative area, and the magnetic anomaly area in the Sichuan basin. The analysis of aeromagnetic anomaly characteristics reveals spatial distribution of the tectonic units and major faults in the Longmenshan mountains, Sichuan basin and the plateau in western Sichuan. There is a correlation between the aeromagnetic anomalies, top and bottom depths of the magnetic bodies and the 2008 Wenchuan M(s)8. 0 earthquake. |
