The Kutonebetsu River Lowland locates in the western coast of the northern part of Hokkaido Island. Discussions are based on results from the interpretation of aerial-photographs, hand-boring surveys, radiocarbon dating using accelerator mass spectrometer (AMS) and FeS2, content analysis of the sediment. \n Two Holocene geomorphic surfaces can be recognized in this lowland. The Holocene sediments consist of a thick clay layer and a 2- to 3-meter-thick herbaceous peat layer overlying basal Neogene mudstone. Judging from the results of FeS2 content analysis, the upper part of the clay layer was deposited in brackish-water environment and the peat layer was deposited in fresh-water environment. \n Late Holocene geomorphic changes of this lowland can be summarized as follows ; \n In the middle Holocene, relative sea-level reached to a little-higher than the present sea-level, and brackish lagoon spread behind coastal barrier. After about 4,000 yrBP, peatland (upper Halocene surface) began to form from the edge of the lagoon. In about 2,900 yrBP, when relative sea-level probably fell, the water-level of the lagoon also dropped and peatland rapidly expanded to lagoon. After that, the river dissected the older surfaces and developed floodplain (lower Holocene surface). \n This geomorphic changes reveal that late Holocene sea-level fluctuation was important factor for the peatland formation in this lowland, and that the tectonic uplift probably occurred in the western coast of northern Hokkaido during the late Holocene.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宮崎大学教育文化学部","subitem_publisher_language":"ja"},{"subitem_publisher":"The Faculty of Education and Culture, University of Miyazaki","subitem_publisher_language":"en"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11403456","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13454021","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大平, 明夫","creatorNameLang":"ja"},{"creatorName":"オオヒラ, アキオ","creatorNameLang":"ja-Kana"},{"creatorName":"Ohira, Akio","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-06-21"}],"displaytype":"detail","filename":"KJ00000228692.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000228692.pdf","url":"https://miyazaki-u.repo.nii.ac.jp/record/1724/files/KJ00000228692.pdf"},"version_id":"1445717d-9fb0-4b7c-a300-167540017a1b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"riverine-coastal lowland, pcatland, sea-level changes, AMS radiocarbon dating, FeS2, content analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"沖積低地, 泥炭地, 海水準変動, AMS14C年代測定, FeS2含有量分析","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"北海道北部、クトネベツ川低地における完新世後半の泥炭地の形成","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"北海道北部、クトネベツ川低地における完新世後半の泥炭地の形成","subitem_title_language":"ja"},{"subitem_title":"Late Holocene Peatland Development in the Kutonebetsu River Lowland, Northern Hokkaido,Japan","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"5","path":["71","25","90","95","229"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-03-21"},"publish_date":"2008-03-21","publish_status":"0","recid":"1724","relation_version_is_last":true,"title":["北海道北部、クトネベツ川低地における完新世後半の泥炭地の形成"],"weko_creator_id":"5","weko_shared_id":2},"updated":"2023-07-29T10:53:37.218833+00:00"}
