Marine magnetic anomalies from the western and northern Philippine Sea: Implications for the evolution of marginal basins
Abstract
A set of processed data is presented together with all available magnetic anomaly data from the West Philippine Basin and the Shikoku Basin. The combined data allows the lineation patterns in these basins to be deduced and the tectonic history of the Philippine Sea to be determined. The correlations indicate that the crust of the West Philippine Basin started to form before anomaly 25 time (approximately 59 m.y. B.P.), probably at the ridge which was the southern boundary of the Pacific plate at that time. The West Philippine margin basin, however, was formed at about 40 m.y. B.P., after the entrapment of oceanic crust by transform faults which changed into subduction boundaries.
