Fig. 7

Analysis results of tube pumice from Taupo ignimbrite (unit 6). The upper images are the cross-sectional images obtained with a DSM-LaRI, b the low-resolution X-ray CT, and c the high-resolution X-ray CT. The lower graphs show the equivalent bubble radius versus the bubble deformation degree. The blue crosses are all the data, and the yellow dots are the average of \(D\) with every radius interval of \(2 \times 10^{ - 2} \;{\text{mm}}\) for a, b and \(5 \times 10^{ - 3} \;{\text{mm}}\) for c. The green-highlighted area shows the range of \(0.025 < R < 0.15 \;{\text{mm}}\)
