The specimen yielded 22,570±60 BP (±1σ). The calibrated age was 27,180−26,589 cal BP (±2σ) and 3000 years older than the previous estimate. Origin and distribution of the Maebashi mudflow deposit were identified by 87Sr/86Sr ratios of volcanic blocks within the mudflow deposits, in comparison with 87Sr/86Sr data for surrounding volcanoes. The mudflow was generated by the collapse of Asama volcano, flowed down along the Agatsuma and Tone rivers, and deposited in the wide area around Maebashi and Takasaki. Distribution of the Stone Age remains appears to reflect the extent of the Maebashi mudflow deposit.", "subitem_description_language": "en", "subitem_description_type": "Abstract"},
