RADIOCARBON DATING OF TREE RINGS FROM THE BEGINNING AND END OF THE YAYOI PERIOD, JAPAN

ABSTRACT We have conducted radiocarbon ( 14 C) dating of Japanese tree rings from 1053 to 921 BCE and 41 130 CE. Dating was also performed using oxygen isotope dendrochronology investigate subtle structures the calibration curve corresponding beginning end Yayoi period in Japan. These two results followed IntCal20, which included C ages Japan-sourced trees. The findings suggest that specimens obtained areas around archipelago may be affected by periodic monsoons ocean, an effect needs further examination.
