From: Clockwise rotation of SW Japan and timing of Izanagi–Pacific ridge subduction revealed by arc migration

Fig. 11

Conceptual tectonic model for SW Japan that can explain the spatiotemporal evolution of arc magmatism. The onset of subduction of the Izanagi plate (IZA) beneath the eastern margin of Eurasia (A), the migration of the arc front to the continental side accompanied by slab shallowing due to the approach of the spreading ridge (B–D), cessation of the arc magmatism accompanied by ridge subduction and formation of the slab window (E), and the onset of subduction of the Pacific plate (PAC) after spreading ridge subduction (F) are shown. The remnants of the arc formed during (A–D) are oriented at an angle of about 20 degrees to the present arc orientation shown in (F). This rotation suggests microplate rotation associated with the IZA–PAC ridge subduction
