Geomagnetic survey was mainly conducted in the region of the southwestern part of the trough, and detected magnetic anomalies with amplitudes exceeding 300 nT. Generally, these anomalies are associated with topographic highs in the trough. The anomalies are distributed discontinuously except the axial rift area of the trough. This anomaly pattern suggests that the back-arc spreading have occurred only within the rift area, the Yaeyama Graben, in the southwestern part of the trough.","subitem_description_type":"Abstract"},{"subitem_description":"DELP 1988航海において,地磁気三成分および全磁力の観測をおもに沖縄トラフの南西部海域で行った.その績果,トラフ底に分布する地形的高まりに対応した300nTをこえる地磁気異常が認められた.地磁気三成分異常について解析した結果,トラフ南西部では,八重山海底地溝域を除いて顕著な磁気異常の連続性は認められなかった.八重山海底地溝域においては,地溝の伸び(ほぼ東西)に沿った地磁気異常の連続性が認められ,地磁気異常の原因物体の2次元的な分布が推定された.八重山海底地溝には,火山岩より成ると思われる海丘が点在している.これらに対応した全磁力異常の分布および三成分異常の解析結果より,堆積層下にも貫入岩体の存在が示唆された.この様なことから,少なくとも地溝東半の約50kmの範囲においては.火山活動をともなう背弧海盆形成の活動が行われたことが推定された.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"127339","nameIdentifierScheme":"WEKO"}],"names":[{"name":"古川, 雅英"}]},{"nameIdentifiers":[{"nameIdentifier":"127340","nameIdentifierScheme":"WEKO"}],"names":[{"name":"近藤, 信哉"}]},{"nameIdentifiers":[{"nameIdentifier":"127341","nameIdentifierScheme":"WEKO"}],"names":[{"name":"三木, 雅子"}]},{"nameIdentifiers":[{"nameIdentifier":"127342","nameIdentifierScheme":"WEKO"}],"names":[{"name":"伊勢崎, 修弘"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032757","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162258","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408972","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute, University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Earth Sciences, Kobe University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Furukawa, Masahide"}],"nameIdentifiers":[{"nameIdentifier":"127335","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kondo, Shinya"}],"nameIdentifiers":[{"nameIdentifier":"127336","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Miki, Masako"}],"nameIdentifiers":[{"nameIdentifier":"127337","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Isezaki, Nobuhiro"}],"nameIdentifiers":[{"nameIdentifier":"127338","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":"2017-06-26"}],"displaytype":"detail","filename":"ji0661005.pdf","filesize":[{"value":"7.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0661005.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32757/files/ji0661005.pdf"},"version_id":"18aa7905-588d-454c-a0a4-b31bc74711da"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Report on DELP 1988 Cruises in the Okinawa Trough : Part 5.
