[T11-O-19] Paleoclimatic Analyses of the Past 200 years Using Cascade Tufa and Stalagmite in Tokunoshima Island, Kagoshima Prefecture, Japan

【ハイライト講演】

*Akira Murata¹, Hirokazu Kato¹, Akihiro Kano¹ (1. The University of Tokyo)

世話人よりハイライトの紹介：鹿児島県徳之島の小原海岸に広く発達するカスケード型トゥファと小島鍾乳洞から採取した石筍の酸素・炭素の同位体記録の変動が検討される．一般的なトゥファの記録が数十年程度であるのに対して，本発表で対象とするカスケード型トゥファは，石筍と同様に長期かつ連続的な古気候記録媒体となる可能性を秘めていることが報告される．※ハイライトとは
