The Permian Sawadani Unit (NC-P), Lower-Middle Jurassic Yusugawa (NC-Js), Sumaizuku (NC-Jα), Kamiyosida (NC-Jβ) units, and uppermost Jurassic-Lower Cretaceous Kashiwagi Unit (NC-JK), technically from top to bottom, are recognized in the Northern Chichibu Belt. The Jurassic-Lower Cretaceous Ohirayama (SC-Jα), Togano (SC-Jβ) and Sambosan (SC-JK) units are recognized in the Southern Chichibu Belt. Oceanic plate stratigraphy for accretionary complexes in the Northern and Southern Chichibu belts are generally similar to each other, but some critical differences are also recognizable. The Sambagawa metamorphism affected accretionary complexes not only of the Northern Chichibu Belt but also of the Southern Chichibu Belt. A 3-D diagram using this unit division for the Chichibu Composite Belt in western Shikoku is depicted. Components of the Kurosegawa Belt are tectonically sandwiched between units of the Northern and Southern Chichibu belts and die out to the northwest. The following processes well explain the distribution pattern of the Kurosegawa Belt in the area : (1) formation of accretionary complexes in the Northern and Southern Chichibu belts, (2) juxtaposition of the Northern Chichibu and Southern Chichibu belts due to large-scale strike slip movement, (3) Sambagawa metamorphism (ca. 100Ma), and (4) local exhumation of deeper part of Southern Chichibu accretionary complexes.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"41591","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Matsuoka, Atsushi"}]},{"nameIdentifiers":[{"nameIdentifier":"41592","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yamakita, Satoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"41593","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sakakibara, Masayuki"}]},{"nameIdentifiers":[{"nameIdentifier":"41594","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hisada, Kenichiro"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本地質学会"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00141768","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00167630","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松岡, 篤"}],"nameIdentifiers":[{"nameIdentifier":"41587","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山北, 聡"}],"nameIdentifiers":[{"nameIdentifier":"41588","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"榊原, 正幸"}],"nameIdentifiers":[{"nameIdentifier":"41589","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"久田, 健一郎"}],"nameIdentifiers":[{"nameIdentifier":"41590","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-30"}],"displaytype":"detail","filename":"10_0009.pdf","filesize":[{"value":"6.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"10_0009.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/3232/files/10_0009.pdf"},"version_id":"589bf82d-f65b-4600-8a55-8f5cb2654413"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Northern Chichibu Belt","subitem_subject_scheme":"Other"},{"subitem_subject":"Southern Chichibu Belt","subitem_subject_scheme":"Other"},{"subitem_subject":"Kurosegawa Belt","subitem_subject_scheme":"Other"},{"subitem_subject":"accretionary complex","subitem_subject_scheme":"Other"},{"subitem_subject":"oceanic plate stratigraphy","subitem_subject_scheme":"Other"},{"subitem_subject":"western Shikoku","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"付加体地質の観点に立った秩父累帯のユニット区分と四国西部の地質","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"付加体地質の観点に立った秩父累帯のユニット区分と四国西部の地質"},{"subitem_title":"付加体地質の観点に立った秩父累帯のユニット区分と四国西部の地質","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","489"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-04-23"},"publish_date":"2008-04-23","publish_status":"0","recid":"3232","relation_version_is_last":true,"title":["付加体地質の観点に立った秩父累帯のユニット区分と四国西部の地質"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:22.592223+00:00"}
