项目摘要

本研究では、全国の埋蔵文化財調査機関と協力して、日本における年輪酸素同位体比の標準変動曲線の時空間的な拡張と気候変動の精密復元を行いながら、酸素同位体比年輪年代法による大量の出土材の年輪年代測定を進める。それにより、全国の遺跡・遺物や土器型式をはじめとした考古事物全般に暦年代を系統的に導入し、気候変動との関係を含む日本の先史時代像全体に対する年代論的な再検討を行うだけでなく、多くの同位体研究者を酸素同位体比年輪年代法の研究に誘い、埋蔵文化財の発掘現場における本方法の持続的な発展を促すために、標準変動曲線のオープンデータベース化を図り、外部からのデータの参照と更新が可能なシステム作りを進めることを、目的としている。平成29年度は、3つの研究グループ、即ち [1] クロノロジー構築班（全国各地での標準変動曲線の確立と公開、及び気候変動の復元）、[2] 年輪年代測定班（出土材の年輪年代測定及び、分析・解析技術の改良と普及）、[3] 土器編年対応班（地域毎での土器編年と年輪による暦年代の対応関係の検討）が、それぞれの目的での研究を開始した。特に、[2]のグループでは、年輪セルロース酸素同位体比の測定による出土材の年輪年代測定を専門とした研究員を一名雇用し、分析・解析の体制を整えると共に、[3]のグループと協力して、弥生時代末期～古墳時代初期の庄内式土器との一括性が明確な大阪府寝屋川市の小路遺跡から出土した多数の水路護岸の矢板材の分析などを開始した。本研究は、平成29年の5月末に、同名の科研費・基盤研究Sの採択の通知を受けて、その研究を終了した。

In this study, we have made a coordinated effort in the study, the national cultural equipment, and the determination of the age of a large number of soil materials in Japan than that in the standard time and space of the standard motion curve, the precision equipment, the precision equipment, and the acid isotope method. In the history of Japan, in the history of Japan, as in the whole history of Japan, in the history of Japan, In this method, it is necessary to improve the performance of the system, to improve the quality of the system, to improve the performance of the system, and to improve the performance of the system. Pingcheng 29, 3-year-old research program, that is, the [1] standard training program is open to the public throughout the country, and the climate test program is open to the public. [2] chronological determination class (measurement and popularization of the age of soil materials, improvement and popularization of analytical techniques), [3] soil tool editing annual training class (regional soil tool editing annual training session), annual soil tool editing annual training session (regional soil tool editing annual training session), annual soil tool editing annual training class (regional soil tool editing annual training class), annual soil tool editing annual training class (regional soil tool editing annual training class), annual soil tool editing annual training class (regional soil tool editing annual training class), annual soil tool editing annual training class (regional soil tool editing annual training class), annual soil tool editing annual training class (regional soil tool editing annual training session), annual soil tool editing annual training class (regional soil tool editing annual training session), annual soil tool editing annual training class (regional soil tool editing annual training session), annual annual training session, annual annual training session, annual annual Special, [2], [2], [2], and [2], [2], [2], [2], [2], [2], [2], [2], [2], [2], [2], [2], [2], and [2], [2], [2], and [2], [2], [2], and [2], [2], and [2], [2], [2], and [3], From the end of the Miyagi Dynasty to the early ancient times, it was clear that most of the yakei plates on the waterway were unearthed from the trail in Sakugawa, Osaka Prefecture. In this study, Pingcheng 29 "at the end of May", with the same name "Scientific Research" basic research S, has been informed that it has been accepted and studied.
