Figure 2: Plagioclase image from Scanning Electron Microprobe.
a). There are gas cavities in the resorbed glass. Gas in glass escaped during the eruption.
b). Boundary between plagioclase and pumiceous glass. There are large gas bubbles in glass, and the cavities in plagioclase are connected with gas bubbles in surrounded glass. Pl = glass, gl = glass.
