SEM images of the water-added sample. a BSE image of a polished surface around the upper and lower sample boundaries. The sample boundary is shown as a white dashed line. The grains with a light gray color, a length of ~ 50 μm, and an aspect ratio of ~ 5 are zoisite, which is seen especially around the sample boundaries. b Enlarged image of the thin section. Large SiO2 materials are shown in dark gray with arrows. They are sometimes segregated, but they are also seen around grain contacts (slightly darker colors), similar to the initial sample (Fig. 1). A reduction of pores is observed, especially around the bulging and transparent portions (see Fig. 5). c, d Secondary electron images of broken surfaces within approximately 200 μm of the sample boundary. Highly elongated grains (lengths of ~ 5 μm and aspect ratios of ~ 5) are developed on the anorthite grains. Vermicular-like features can also be observed in (d)
