Significance of the Ikenotaira Interstadial Indicated by Moraines on Mt. Kumazawa of the Kiso Mountain Range, Central Japan
KOBAYASHI, KUNIO
SHIMIZU, HIDEKI
From tephra cover on the outermost moraine in the Ikenotaira cirque on Mt. Kumazawa of the Kiso mountain range, a small amount of air-borne scoria from Ontake volcano was collected. The scoria is identified with that of the scoria-fall deposit Sc-I which within the section of the air-laid Younger tephra unit of the so-called Shinshu Loam Formation lies in the basal part. The radiometric age of the Kisogawa volcanic mudflow associated with the Sc-I approximates 27,0001t C years ago, indicating that the outermost moraine be assigned to the pre-Paudorf glacial stade, whereas the upper two moraines should postdate the Paudorf interstadial. The interval indicated between the lower two moraines is emphasized to establish the Late Quaternary chronology. The date of the Ikenotaira interstadial also supports that simultaneous uprise of sea level may have taken place.
