Site mean magnetic directions of the Imaichi deposit are all of reversed polarity with declinations deflected slightly to the east. These directions are consistent with those of the Azuki and the Ku6C ashes. Magnetizations of the Yabakei, the Pink, and the O7 ashes are also consistent with one another. All are characterized by shallow inclinations (about 30°) of normal polarity with slightly westerly declinations. The identical paleomagnetic directions of these widespread tephra confirm correlations that have been proposed mainly on the basis of glass and mineral chemistry, and provide a tephrochronological linkage between the source volcanic area and the lacustrine or marine sequences over distances of at least 1000 km. This linkage allows us to correlate the oxygen isotope record of the Kazusa Group in Boso Peninsula with the alternating marine/non-marine lithology of the Osaka Group in the Kinki district. Radiometric dates from the Yabakei and the Imaichi pyroclastic-flow deposits are concordant with the astronomically-calibrated geomagnetic polarity time scale."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383951793283572097","@type":"Researcher","foaf:name":[{"@value":"Akira
