Fig. 2: Variations in water content in glass embayments and inclusions.
From: Magma chamber decompression during explosive caldera-forming eruption of Aira caldera
a Line profile of water content along the glass embayments. The distance shown in the horizontal axis of each diagram corresponds to the depth of the measured point from the entrance to the glass embayment. b Variation in water content of the plateau part of the glass embayment found in the quartz phenocrysts (deeper than ~100 μm from the surface of the phenocryst). Vertical axis shows the percentage. c Variation in water content of the isolated glass inclusions in the orthopyroxene and quartz phenocrysts. Vertical axis shows the percentage.
