title="Izanagi">Izanagi</a>) was an ancient <a href="/wiki/Tectonic_plate" class="mw-redirect" title="Tectonic plate">tectonic plate</a>, which began <a href="/wiki/Subduction"

title="Megaannum">Ma</a> (million years ago). The rapid plate motion of the Izanagi plate caused northwest <a href="/wiki/Japan" title="Japan">Japan</a> and the outer zone of southwest Japan to drift northward. High-pressure <a href="/wiki/Metamorphic_rocks" class="mw-redirect" title="Metamorphic rocks">metamorphic rocks</a> were formed at the eastern margin of the drifting land mass in the Sanbagawa metamorphic <a href="/wiki/Orogenic_belt" title="Orogenic belt">belt</a>, while low-pressure metamorphic rocks were formed at its western margin in the Abukuma metamorphic belt. At approximately 55 Ma, the Izanagi Plate was completely subducted and replaced by the western <a href="/wiki/Pacific_plate" title="Pacific plate">Pacific plate</a>, which also subducted in a northwestern direction. Subduction-related <a href="/wiki/Magmatism" title="Magmatism">magmatism</a> took place near the <a href="/w/index.php?title=Ryoke_belt&action=edit&redlink=1" class="new" title="Ryoke belt (page does not exist)">Ryoke belt</a>. No marked tectonics occurred in the Abukuma belt after the change of the subducted plate. </p><p>The discovery of an extinct <a href="/wiki/Jurassic" title="Jurassic">Jurassic</a>–<a href="/wiki/Cretaceous" title="Cretaceous">Cretaceous</a> spreading system in the northwest Pacific led to the introduction of the extinct <a href="/wiki/Kula_plate" title="Kula plate">Kula plate</a> in 1972.
