Outline of Final Research Achievements |
Main tree species used for wooden outer coffin & wooden coffin from the Han Dynasty was identified as Chinese fir (Cunninghamia lanceolate H.) A tree-ring pattern of this species was examined, and the result indicated that dendrochronological analysis based on the ring pattern was applicable for the study of the wooden outer coffin & wooden coffin. The tree-ring pattern with unknown calendar years was crossdated with 10 highly correlated samples, and a chronology of 564 years was successfully developed. The result of the 14C wiggle-match dating method conducted on one of the samples showed that the 564 years fell between B.C.6C and A.D.1C. In the future, it is considered that this constructed chronology would be helpful for dating the wooden outer coffin & wooden coffin from the Han Dynasty.

Academic Significance and Societal Importance of the Research Achievements |
漢代出土木槨・木棺材の主要樹種であるコウヨウザンの年輪を用いて年代測定の基準となる年輪パターンを564年間分(B.C.6世紀~A.D.1世紀)作成したことにより、前漢、後漢の木槨墓や木棺墓に使用されている木材の年代を明らかにすることが可能となった。この基準パターンを使って得られる成果は土器やその他の共伴遺物の編年研究に大きく貢献できる。かつ、その成果は中国国内ばかりでなく、わが国の弥生時代・古墳時代の年代観にも大きな影響を与えることになり、その意義は極めて大きい。
