Figure 4

Zero-order magnetic enhanced analytic signal map of the West Philippine Basin. The zero-order enhanced magnetic analytic signal amplitude is higher to the east of the LOFZ than the west. Bathymetric contour interval is 500 m. Bold lines: magnetic isochrons; White dashed line: relict spreading center; Yellow bold line: Benham Rise magma propagation area. BR: Benham Rise; GR: Gagua Rise; UP: Urdaneta Plateau; LOFZ: Luzon–Okinawa Fracture Zone; OSC: overlapping spreading center; PKR: Palau–Kyushu Ridge.
