| Research Abstract |
In this research, we intended to establish archaeological chronology defined by calendar dates, using the AMS radiocarbon dating and calibrated dates based on Intcal 98 and Intcal 04.
Dating samples were collected from various sites in Hokkaido.
In National Museum of Japanese History, those samples were processed appropriately by AAA method.
After that, radiocarbon dating of them were performed in some analysis organizations. Then, radiocarbon dates of them were calibrated in National Museum of Japanese History, and calendar dates of them were obtained.
Consequently, following results were obtained
1. In Hokkaido, the marine reservoir effects were identified by pottery adhesion carbon samples unearthed not only from coastal sites but also from inland sites.
2. Therefore, plant residues are the most effective as samples of radiocarbon dating..
3. The indicated ages were contained in the following times.
First half of Epi-Jomon Culture BC 4th century-AD 2nd century
Second half of Epi-Jomon Culture AD 2nd century-AD 4th century
Middle period of Ohotsk Culture AD 5th century-AD 7th century
Late period of Ohotsk Culture AD 6th century-AD 8th century
Final period of Satsumon Culture AD 13th century
Moreover, the conventional measurement result was collected and the radiocarbon dating database in Hokkaido was created.
