Figure 1From: Volatile (F and Cl) concentrations in Iwate olivine-hosted melt inclusions indicating low-temperature subductionDiagram reporting SiO 2 as a function of K 2 O and Na 2 O (wt.%) of the Iwate glassy melt inclusions. The all fall in the basalt domain with few of them touching the basaltic-andesite domain. Inset: map of NE Japan arc. The volcanic front is indicated by a line. Iwate volcano is a front arc volcano.Back to article page
