The eruptive products of Ashitaka volcano are divided into four stratigraphica groups: Older group, Middle group, Younger group and Youngest group. The Older group is mainly composed of many thin flows of basaltic lava (SiO2=49-53%) and voluminous tuff breccia. These lava flows are interstratified with Shimowada loam formation. The upper unit of the Older group consists of breccia pipe deposits in Kumagaya crater, and some tephra layers of Mishima loam formation east of Ashitaka volcano are air-fall deposits from the pipe. The middle group is composed of voluminous tuff breccia (Mtb), occupying more than half of the volume of the main body. The volcanic fan deposits are secondary deposits derived from Mtb. It is interstratified with a T-6 tephra layer which erupted from Ashitaka volcano 170,000 y. B.
