Description
Kd 38 pyroclastic key bed which is intercalated near the boundary of Pliocene-Pleistocene series is a widespread volcanic ash bed and important key bed for the stratigraphy of the Kazusa Group. Redefined Kd 38 pyroclastic key bed as the Kd 38 volcanic ash bed were reexamined for correlation in thirteen localities in the Boso Peninsula based on their lithofacies and petrographic properties. Thirteen localities are divided three areas, which are namely Sano-Kaisho, Yokoze-Oppara and Orikizawa-Koshikoma areas based on lithofacies of Kd 38 volcanic ash. Lithofacies and petrographic properties of Kd 38 volcanic ash are different at each area. However, Kd 38 volcanic ash bed in different localities can be correlated by correlation of the Kd 38.2 volcanic ash bed below the Kd 38 volcanic ash bed and relationship of lithofacies and petrographic properties. Their differences of lithofacies and petrographic properties of the Kd 38 volcanic ash bed at each localities reflects the difference in depositional processes of this volcanic ash after fallout.
