It was difficult to compile dates of archaeological sites with shell midden. There were not so many dates those were reported with the contemporary type of pottery in detail. Shell and charcoal remains excavated from the same layer as pairs were measured and compared. According to the sample of the shell midden in the Sanriku district, the ages of the shell samples are 200-300 years older than those of charcoal fragments. The dates of shell samples should be calibrated with the regional correction value (ΔR).Direct dating of a potsherd itself has been investigated for 'fiber-tempered pottery'. Contaminants alone can be removed when a suitable moderate condition of chemical treatment. About 40 potsherds of the Earliest and Early Jomon period have been dated. The measured values of δ ^<13>C were about 25‰, and C4 plants have not been used as a organic temper. The impression of fiber, remained on the surface or inside of the potsherd, was observed by SEM using the replica method. The fiber was seemed to be short and straight.Our project is now reconstructed for a successive investigation.

有贝壳壳的考古遗址的日期很难编制。没有那么多关于当代陶器类型的详细日期报告。从同一层出土的贝壳和木炭残骸成对地进行了测量和比较。根据三陆地区的贝壳堆样本，贝壳样本的年龄比木炭碎片的年龄早200-300年。壳体样品的日期应使用区域校正值（ΔR）进行校准。对“纤维回火陶器”的陶器碎片本身进行了直接测年的研究。在适当的适度化学处理条件下，污染物本身就可以被去除。最早和早期绳文时期的陶器碎片约有40件。测量值δ ^<13>C约为25‰，C4植物未被用作有机回火。采用复刻法，利用扫描电子显微镜观察了陶瓷碎片表面和内部残留的纤维印痕。纤维看起来又短又直。我们的项目现在正在重建，以便进行后续调查。
