英文摘要
Adak Island, Aleutian Islands, Alaska is covered with Holocene sequences of soil-tephra complexes. Tephra layers are useful for establishing a chronographic framework on the island. Black (1976) described the three conspicuous tephra deposits (Main, Intermediate and Sandwich). This study conducted coring peat deposits near Haven Lake, in order to re-evaluate the chronological framework. This study obtained 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.
