In order to reveal the origin of the marsh, we collected the three cores (KS-0412-1, 2 and 3) in December, 2004. This paper presents preliminary results (i.e., physical properties of sediments, pollen and phytolith assemblages and radiocarbon date) of the KS-0412-3 core. We obtained three radiocarbon dates for plant fragments. The sedimentation rate of the marsh deposits is estimated to be 4.1 mm/yr. This rate implies that the marsh deposits have been accumulated since approximately 1200 cal AD. The pollen and phytolith analyses indicate that rice field was buried by medium to coarse sand layer at 1400 cal AD, since then the marsh has been sustained. This result is consistent with insect and diatom assemblages in the 0304 core (Okuno et al., 2004)., タンデトロン加速器質量分析計業績報告 Summaries of Researches Using AMS 2004 (平成16)年度}, pages = {156--168}, title = {北部九州の樫原湿原におけるボーリング・コア試料 (KS0412-3)の分析結果(速報)(タンデトロン加速器質量分析計業績報告2004(平成16)年度)}, volume = {16}, year = {2005} }
