説明
Abstract A large number of tephra layers deposited over the past 40,000 years in Japan have been studied by means of newly developed techniques as well as the traditional radiocarbon ( 14 C ) method. The samples for 14 C dating were commonly charcoal and wood directly covered or involved in tephra-fall and pyroclastic flow deposits. Recently, the 14 C dates measured for paleosols directly underlying a tephra layer have proved to represent the accurate eruption age of the tephra, and have successfully established the high-resolution eruptive histories of several volcanoes. In addition, oceanic and lacustrine sediments have preserved a large number of tephra layers, and accelerator mass spectrometry 14 C measurements on terrestrial macrofossils from varved sediments have provided highly accurate ages for tephra layers. Wiggle matching of 14 C ages from several horizons of peat sediments to INTCAL98 calibration data that was established by dendrochronology as well as by varve chronology has enabled us to obtain highly accurate ages of tephras intercalated in the peat deposits.
