Each subunit is composed mainly of chert beds and overlying clastic rocks. This unit is characterized by a pile-nappe structure of chert-clastics sequences. Middle Jurassic radiolarian fossils were found from the uppermost part of chert beds of Subunit 1 and Subunit 2 as well as from the siliceous mudstone of Subunit 1 and Subunit 2. The transitional horizon from chert to clastics in these subunits is of Bajocian to early Bathonian age. Judging from lithological features and geological age, the Kashiwagi Formation and the Hashidate Group in the Northern Chichibu terrane should not be the origin of the Ryokami-yama chert unit. This disagrees with the previous interpretation. The Ryokami-yama chert unit is better compared to the Unazawa Formation in the Southern Chichibu terrane or to the Kamiyoshida Formation in the Northern Chichibu terrane.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"41459","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yoshida, Kazuhiro"}]},{"nameIdentifiers":[{"nameIdentifier":"41460","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Matsuoka, Atsushi"}]}]},"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":"吉田, 和弘"}],"nameIdentifiers":[{"nameIdentifier":"41457","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松岡, 篤"}],"nameIdentifiers":[{"nameIdentifier":"41458","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_0011.pdf","filesize":[{"value":"2.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"10_0011.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/3211/files/10_0011.pdf"},"version_id":"d17ccd81-d806-4273-967f-a0331910cc7e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Ryokami-yama chert unit","subitem_subject_scheme":"Other"},{"subitem_subject":"Jurassic","subitem_subject_scheme":"Other"},{"subitem_subject":"accretionary complex","subitem_subject_scheme":"Other"},{"subitem_subject":"chertclastic sequence","subitem_subject_scheme":"Other"},{"subitem_subject":"pile-nappe structure","subitem_subject_scheme":"Other"},{"subitem_subject":"radiolaria","subitem_subject_scheme":"Other"},{"subitem_subject":"Chichibu terrane","subitem_subject_scheme":"Other"},{"subitem_subject":"Kanto Mountains","subitem_subject_scheme":"Other"},{"subitem_subject":"Saitama Prefecture","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":"関東山地秩父累帯両神山チャートユニットのパイルナップ構造","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"関東山地秩父累帯両神山チャートユニットのパイルナップ構造"},{"subitem_title":"関東山地秩父累帯両神山チャートユニットのパイルナップ構造","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":"3211","relation_version_is_last":true,"title":["関東山地秩父累帯両神山チャートユニットのパイルナップ構造"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T04:33:58.078195+00:00"}
