| Research Abstract |
Inter-annual variations in tree-ring cellulose oxygen isotope ratios are in principle dependent only on the two meteorological factors, precipitation isotope ratio and relative humidity, irrespective of differences in tree species. Based on this knowledge, we have established several millennia length of tree-ring cellulose oxygen isotope chronologies all over Japan by analyzing of various types and periods of tree ring samples obtained from wooden materials such as buried natural logs, excavated artefacts and old architectures made of long-living species like cypress and cedar in addition to their living old trees. The newly developed chronologies are now applicable to dating of various species of archaeological wooden materials and in fact have begun to be successfully applied to date many wooden materials excavated from many archaeological sites in various regions, such as Tokai, Hokuriku and Kinki districts since Jomon-era.
