Tephra layers are useful for establishing a chronographic framework on the island. Black (1976) described the three conspicuous tephra deposits (Main, Intermediate and Sandwich). We conducted coring peat deposits near Haven Lake, in order to re-evaluate chronological framework. This paper presents petrography and radiocarbon date using accelerator mass spectrometry (AMS). Eruptions of the Main, Intermediate, Sandwich, YBO and Forty Year tephra were dated to approximately 9.5, 7.2, 4.7, 3.6 and 0.4 cal kBP, respectively., 名古屋大学年代測定総合研究センターシンポジウム報告}, pages = {133--136}, title = {アラスカ,アリューシャン列島のアダック島でのテフロクロノロジー}, volume = {25}, year = {2014} }
