These strata are separated by high angled reverse faults into five subparallel major zones. In addition to these large faults, many smaller reverse faults and isoclinal folds exist in the present area. ...","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_12_description_45":{"attribute_name":"学位授与年度","attribute_value_mlt":[{"subitem_description":"1981","subitem_description_type":"Other"}]},"item_12_dissertation_number_47":{"attribute_name":"報告番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第146号"}]},"item_12_relation_37":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"本文はOPACにあり"}],"subitem_relation_type":"hasFormat","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.tulips.tsukuba.ac.jp/opac/volume/512936","subitem_relation_type_select":"URI"}}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"久田, 健一郎","creatorNameLang":"ja"},{"creatorName":"Hisada, Kenichiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"34656","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2013-12-18"}],"displaytype":"detail","filename":"A0146.pdf","filesize":[{"value":"145.0 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"abstract","url":"https://tsukuba.repo.nii.ac.jp/record/8316/files/A0146.pdf"},"version_id":"49c26999-8eea-467d-815a-2393a7c29890"}]},"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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Stratigraphy and geologic structure of the Chichibu and Northern Shimanto Belts in Kanto mountains, Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Stratigraphy and geologic structure of the Chichibu and Northern Shimanto Belts in Kanto mountains, Japan","subitem_title_language":"en"}]},"item_type_id":"12","owner":"1","path":["254"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-07-25"},"publish_date":"2007-07-25","publish_status":"0","recid":"8316","relation_version_is_last":true,"title":["Stratigraphy and geologic structure of the Chichibu and Northern Shimanto Belts in Kanto mountains, Japan"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-02T01:11:34.118923+00:00"}
