Re-$$^{14}$$C dating of wood fossils from the gravel beds at Sebadani, the upper reaches of Azusa River, central Japan

Oikawa, Teruki*; Sasao, Eiji   ; Hoshino, Yasuharu*

The depositional age of gravel beds at the Sebadani, in the upper reaches of Azusa River at the Hida Mountain Range has been determined by AMS $$^{14}$$C dating. We measured the four new AMS $$^{14}$$C dating of wood fossils in the gravel beds of Sebadani. The previous study estimated that the formation age of this gravel beds is 70,000-50,000 yr BP which corresponds to marine isotope stage (MIS) 4. However, the new obtained ages were ${it ca}$. 48 ka BP from the wood fossils in the gravel beds.
