Figure 3From: Water content in arc basaltic magma in the Northeast Japan and Izu arcs: an estimate from Ca/Na partitioning between plagioclase and meltRelation between measured H 2 O content in lt and calculated H 2 O content using hygrometers. Hygrometers used are of this and previous studies listed. Experimental data that was plotted in this figure is listed in Additional file 5: Table S3.Back to article page
