“…Spinel lherzolite is employed as the source material, because low-alkali tholeiitic magmas in the NVZ are believed to segregate from underlying lher zolitic upper mantle at the pressure around 10 kb, where spinel is thought to be the most pro bable stable aluminous phase (Tatsumi, 1986;Nakagawa et al, 1988). The modelling is based on the following assumptions: (1) the spinel lher zolite consists of 58% olivine, 25% orthopyrox ene, 15% clinopyroxene and 2% spinel by weight, corresponding to the modal composition of KLB-1, the most undepleted spinel lherzolite xenolith from Kilborne Hole, New Mexico (cf.…”

“…Several petrologists have favored such a mechanism to explain the low Mg and Ni contents in basalts and andesites from the NVZ (Tatsumi et al, Table 6. Assumed melting relations among the phases in spinel lherzolite and the ratio of phases incorporated into the melt in the melting intervals from 0-5%, 5-25%, and >25% 1983; Yoshida and Aoki, 1988;Sakuyama and Nesbitt, 1986;Nakagawa et al, 1988;Fujinawa, 1988).…”

Abstract:We review the evolution of late Cenozoic magmatism in the NE Japan arc, and examine the relationship between the magmatism and the crust-mantle structure. Recent studies reveal secular changes in the mode of magmatic activity, the magma plumbing system, erupted volumes and magmatic composition associated with the evolution of crust-mantle structures related to the tectonic evolution of the arc. The evolution of Cenozoic magmatism in the arc can be divided into three periods: the continental margin (66-21 Ma), the back-arc basin (21-13.5 Ma) and the island-arc period (13.5-0 Ma). Magmatic evolution in the back-arc basin and the island-arc periods appears to be related to the 2D to 3D change in the convection pattern of the mantle wedge related to the asthenosphere upwelling and subsequent cooling of the mantle. Geodynamic changes in the mantle caused back-arc basin basalt eruptions during the back-arc basin opening (basalt phase) followed by crustal heating and re-melting, which generated many felsic plutons and calderas (rhyolite/granite phase) in the early stage of the island-arc period. This was followed by crustal cooling and strong compression, which ensured vent connections and mixing between deeper mafic and shallower felsic magmas, erupting large volumes of Quaternary andesites (andesite phase).Gold Open Access: This article is published under the terms of the CC-BY 3.0 license.The NE Japan arc is a typical island arc associated with a cold subduction zone. It is one of the most well-known island arcs on Earth and provides a useful model for our understanding of how subduction zones produce magmas, including andesites. The NE Japan arc is related to the westward

“…Circles represent Quaternary stratovolcanoes in the northeast Japan arc. The distribution of the volcanoes is from Nakagawa et al (1988). The distribution of the volcanoes are divided into four volcanic zones: Aoso-Osore (green circle), Sekiryo (orange circle), Moriyoshi (yellow circle), and Chokai (purple circle) zones from trench to rear arc side (Nakagawa et al, 1988 …”
