| Outline of Final Research Achievements |
We tried reconstruction of paleoenvironment by carrying out geological boring survey in Okayama Plain located in the southern Okayama district and were able to obtain the data for considering sea level change by analyzing C14 and Diatom from Early Jomon to Early Yayoi periods. Based on it, we considered reexamination of site distribution and excavation reports, and estimated the coastline of each time.
This study revealed that marine regression in Middle Jomon period and re-transgression in Late Jomon period likely affect sites-dynamics in this area. This result has impact to reconsider the previous assumption.
