... of WPB is the trapped basin model (e.g., Uyeda and Ben-Avraham, 1972 ), where an ocean basin spreading center is partitioned by the inception of a subduction zone. To the north of the WPB is a Mesozoic arc terrane that comprises three remnant arcs, the Amami Plateau, Daito Ridge, and Oki-Daito Ridge...

At the north it is terminated both topographically and structurally by several subparallel ridges from the southeast that intersect the continental slope—the Kyushu-Palau Ridge (the longest one) and the Daito and Oki-Daito Ridges ( Fig. 1 ). A trench structure, the Nankai Trough ( Hilde et al...

... Sea Plate and the Pacific Plate, as well as the orientation of the proto-Palau-Kyushu Ridge, indicate that strike-slip movement was occurring along this boundary, accommodating the opening of the West Philippine Basin. It is very possible that a small amount of opening occurred within the Minami-Daito...
