 note = {application/pdf, 論文(Article), Aso valley (Asodani) is the northern part of Aso Caldera crater which made by depression after the forth of Aso pyroclastic eruptions, also has a floor of 470-500m altitude, that is surrounded by 350-500m high caldera rim at the north, and the central Aso volcano is situated at the south. The upper part of bottom sediments of Asodani is mainly composed sand, silt and clay in the main area, in which a wide fan spreads on the eastern floor and a meander river plane om the midstream of Kuro river (Kurokawa) on the western one. The under parts of sloop beside of the caldera rim are often formed by gravel and coarse materials from the cliff. Formations in the midstream of Kurokawa started deposition as a gravel bed formed by stream on the bottom of the valley during in the late period of the Last Glacial Age, and deposited silt and clay in a lake during 21,000 to 8,800 yBP. After 8,800 yBP, the deposition of Kurokawa started again in the area and the sedimentary environment is continuing to today. On the other hand, it is assumed that fan deposition has continued on the eastern part of Asodani after the Last Glacial Age., http://gcmuseum.ec-net.jp/},
