 note = {The Iwanai Plain lies on the coast of Sea of Japan, southwestern Hokkaido. The authors have researched two boring cores (IWS-1 and IWS-2) in Sokonai branch of Horikappu River by means of lithological analysis, AMS14C-dating, and pollen analysis, and illustrated the geological profile along the branch from boring logs. This study revealed that the section from the ground level to 19.35 m in depth of IWS-1 core (30.45 m in length) is considered as an alluvium (Chuseki-so) consisting of land elevation part, uppermost part of peat and main part of mud and sand in descending order. On the other hand, the section below 19.35 m of IWS-1 core, which showed the AMS14C date of >49,700 cal.yBP, is considered as the stratum MIS 7 based on comparison with the upper part of the column 100 m all-core boring in northwestern corner of Imanai-daichi Plateau., 北海道岩内平野の堀株川支流宿内川沿いでの30.45m，12m長のボーリング孔のコア観察，AMS14C年代測定，花粉分析を行い，周辺のボーリング資料を収集し，断面解析を行った．その結果，両ボーリング孔では深度19.35m（標高-12.3m）に沖積層の下限があり，沖積層は上位より，堤防盛土，最上部泥炭層，主部泥砂層に区分できる．沖積層の下位層（更新統）については，>49,700cal.yBP[NUTA2-25953]のAMS14C年代が得られ，岩内台地北西端の100mオールコアボーリング孔への対比からMIS7？期ではないかと考えられる．},
