Study on Jomon Chronology by AMS Radiocarbon Dating at the First Half of Jomon Period Of East Japan

通过对坑居的碳化物和陶器的碳化材料的年代测定，发现时代的开始相当于或超过15000年。根据对水子山种子种类的测量，可以推测绳纹时代的早期大约早7500-7000年。它在调查的目的是恢复过程中剩余的未知，发现。它收集了大量的数据。我们研究了在ideuenhara遗址被埋葬的坑居状态。在这个时期，大约是400年，在公元前4600年到4200年之间。这些结果使得估计绳纹时期的日期成为可能。初期：15700 - 11600 cal b.p.最早时期：11600 - 7000 cal b.p.珍珠期：7000 -5470 cal b.p.中期：5470-4420 cal b.p.

By period measurement of the carbides from pit dwelling and the carbonization materials of the earthen vessel, it found that the beginning in the times went back equal to or more than about 15,000 years before.It was possible to estimate that the period of early Jomon stage than the measurement of the seed kind from MIZUKO Shellmidden, is about 7500-7000 years before.It investigated in the purpose to restore the process of the remaining unknown, finding. It gathered a lot of data.We examine a state of pit dwelling being buried at IDEUENOHARA site. In the period, it was about 400 years, between 4600 and 4200 years B.P.The results made it possible to estimate dates for each Jomon period.Incipient period:15,700-11,600 cal B.P.Earliest period:11,600-7,000 cal B.PEarly period:7,000-5470 cal B.PMiddle period:5470-4420 cal B.P
