Although inoceramid zones are important chronostratigraphic tools for the Japanese Upper Cretaceous, some recent studies suggested chronostratigraphic discrepancies between mega-and microfossil biochronologies from the Yezo Group in Hokkaido, Japan. Carbon isotope profiles from organic matters obtained in this study from three sections of Hokkaido resemble to isotope profiles from carbonate in England calibrated by biochronology with Tethyan index fossils. The carbon isotope profiles from the Kotanbetsu and Oyubari areas show negative shift segment through the Inoceramus hobetsensis Zone, stable value segment from the upper part of the Inoceramus hobetsensis Zone through the Inoceramus teshioensis Zone and gradual positive migration segment in the Inoceramus uwajimensis Zone and the Inoceramus amakusensis Zone in an acending order. This stratigraphic pattern of carbon isotope curve corresponds to the pattern characterizing the middle Turonian to lower Santonian for the England section. Short term positive excursions (as large as 0.5～1.0‰) superimposed on the long term fluctuation are observed in the Inoceramus hobetsensis Zone from the three sections. They may be potential stratigraphic markers correlative to the similar positive excursions observed in many European sections.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学大学院自然科学研究科","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本地質学会"}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本地質学会の許諾を得て登録"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0016-7630","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"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":"土屋, 健"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"長谷川, 卓"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Pratt, Lisa M."}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"AN00141768-HASEGAWA-109.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN00141768-HASEGAWA-109.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/10310/files/AN00141768-HASEGAWA-109.pdf"},"version_id":"82641ef9-98be-4109-a7cb-b0b842a40ae7"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"北海道蝦夷層群における炭素同位体比曲線とイノセラムス生層序の対応関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"北海道蝦夷層群における炭素同位体比曲線とイノセラムス生層序の対応関係"},{"subitem_title":"Stratigraphic relationship between diagnostic carbon isotope profiles and inoceramid biozones from the Yezo Group, Hokkaido, Japan","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["937"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"10310","relation_version_is_last":true,"title":["北海道蝦夷層群における炭素同位体比曲線とイノセラムス生層序の対応関係"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T17:38:54.574451+00:00"}
