Abstract

Abstract

In this paper, we analyze characteristics of magnetic anomalies calculated from NGDC720 geomagnetic model in the Philippine Sea plate and then decompose magnetic anomalies into the shallow and the deep components. Further, we interpret the causes of magnetic anomalies in the study area. Magnetic anomalies in the Philippine Sea plate not only show tectonic features in the shallow part of the lithosphere, also imply the deep structure information. In the Philippine basin and Daito tectonic zone, shallow magnetic anomalies inherit deep structural features better and magnetic characteristics in these regions reflect the integrity of the lithosphere. The shallow magnetic anomalies in Shikoku and Parece Vela basin show the characteristics corresponded with spreading axis during about 10Ma and magnetic anomaly trends do not agree with those of the seafloor structures. In the Parece Vela basin, the deep anomalies show a consistency with those in Philippine basin, which indicates that Parece Vela basin might have undergone a similar evolution of the Philippine basin.
