The formation of Chronology on Hokkaido Archaeology since Ancient age till Early Modern Times, by calibrated dates of radiocarbon dating

本研究采用AMS放射性碳测年法和基于Intcal 98和Intcal 04的年代校正法，从北海道各遗址采集年代样品，在国立历史博物馆用AAA法进行适当处理，然后在一些分析机构进行放射性碳测年，建立以日历为依据的考古年代学。然后在国立历史博物馆对它们进行了放射性碳定年，并获得了它们的历法年代。在北海道，不仅从沿海遗址，而且从内陆遗址出土的陶器粘附碳样品鉴定了海洋水库效应.因此，植物残体是最有效的放射性碳测年样品。3.所示的时代包含在以下时间。Epi-Jomon文化前半期公元前4世纪-公元2世纪Epi-Jomon文化后半期公元2世纪-公元4世纪Ohotsk文化中期公元5世纪-公元7世纪Ohotsk文化晚期公元6世纪-公元8世纪Satsumon文化末期公元13世纪此外，收集常规测量结果并建立北海道放射性碳测年数据库。

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 obtained1. 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 centurySecond half of Epi-Jomon Culture AD 2nd century-AD 4th centuryMiddle period of Ohotsk Culture AD 5th century-AD 7th centuryLate period of Ohotsk Culture AD 6th century-AD 8th centuryFinal period of Satsumon Culture AD 13th centuryMoreover, the conventional measurement result was collected and the radiocarbon dating database in Hokkaido was created.
