抄録

In 1988, a thin volcanic ash layer was found in the peat layer from nine survey areas of the Choda and Matsukawado archaeological sites, Kasugai City, Aichi prefecture.<br>This layer, about 4mm thick, is composed of light reddish brown to pinkish white and fine to medium-grained ash. It consists chiefly of glass (mainly C-type shards with refractive index of 1.499-1.504; mode 1.501-1.502), which small amounts of plagioclase, orthopyroxene (γ=1.703-1.705), amphibole, biotite and clinopyroxene.<br>The ¹⁴C age of the peat layer from the horizon immediately beneath the ash layer is 3, 120±120y.B.P.; this ash layer was found above a bed containing late Jomon potsherds and below a bed containing final Jomon potsherds. So it can be said that this volcanic ash fell around the fine of the boundary between the late and final Jomon Period.<br>This is probably the first time in the lowland Kinki and Chubu district that the ash layer of this period has been recognized as a visible stratum.<br>The authors named the ash the “Matsukawado Volcanic Ash Layer” (MT) after the layer was discovered.
