| Research Abstract |
For reconstructing the paleoenvironment and prehistoric human life through estimating of the origin of organic matter adhering to and adsorbing in the potsherds, we measured radiocarbon ages, stable isotopes, and lipid compositions. By especially using various kinds of remains at the same layers excavated from the site with a clear archaeological context and scientifically identified samples, we get the following two results ;
1) The origin of millet cultivation and diffusion into Japanese archipelago
There is no reliable evidence analyzed by radiocarbon dating so far for millet utilization in the Jomon period. Therefore, we also review the dates of charred remains on potsherds which are estimated as C4 plants based on stable isotopic analysis. These dates of millets are compared with that of the adoption of irrigated rice cultivation to discuss the routes and times of their diffusion into Japanese archipelago. Consequently, wide spreading of millet cultivation seems to have been from the end of the Early Yayoi to the beginning of the Middle Yayoi period at Kyusyu, Kinki and Toukai area (400-300 cal BC).
2) The reconstruction of diet and paleoenvironment by apparent marine reservoir effect
We can use apparent marine reservoir age difference of the archaeological remains to infer details of paleodiets and inhabits and, hence, paleomarine environments.
