The analyses were conducted with grass seeds and plant stems collected from boring core samples at the Hachiryu marsh, Aichi Prefecture, central Japan. Radiocarbon age of the grass seeds obtained from a depth of 28 to 30 cm was 53 ± 2O yrsBP, and that of plant stems from a depth of 51cm was 72 ± 20 yrsBP. Many fossil insect remains, plant macrofossil and diatom fossils also found from the boring core. Judging from radiocarbon ages and paleontological information, it is suggested that the formation of Hachiryu marsh dates back to the middle of the Edo period. Farther analyses of the boring core are likely to clarify the environment of ancient Hachiryu marsh., 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 = {125--132}, title = {愛知県八竜湿地におけるボーリング試料の年代と古環境}, volume = {25}, year = {2014} }
