The Quaternary terrace (figure 5) extends 8 km along the River Dozangawa and is composed of a bed of pumice of hypersthene-brown hornblende-quartz-plagioclase (andesine and labradorite)-glass-dacite., In parts, it rests upon a flow of hornblende-biotite-quartz-plagioclase (andesine)-glass-dacite., The characteristics of geomorphological (figure 1) together with geololgical feature (figures 2, 3, and 4) of the bed suggest it to be nothing but a pumice flow from the definite position near the southwestern end of the terrace, where a pan-shaped depression, two kilometers in diameter, is now observed (figure 1)., The depression may exhibit a small caldera closely related to the pumice, the volume of depression being estimated as 0.,8 km^3, while that of the pumice flow 1.,4 km^3.,
