Earthq. Res. Inst., 42, 555-570, 1964). Computation is made following Vacquier's method in which uniform magnetization is assumed. The results indicate that these seamounts are magnetized normally in declination but much shallower or reversed in inclination compared with the present geomagnetic field. Depending on the relative intensity of induced magnetization and remanent magnetization, the estimated palaeomagnetic pole positions fall in the central to north Atlantic Ocean. Some Cretaceous index fossils were reported from one of the seamounts. Some speculations are made regarding the possible significance of the obtained pole positions on the movements of ocean floors.","subitem_description_type":"Abstract"},{"subitem_description":"本州東北部および北海道沖の太平洋に存在する4個の海山について,その測深結果および,磁気測量(プロトン磁力計による全磁力)結果にもとづき,磁化方向,強度を推定した.推定にはVacquierの方法を用い,計算はスタンフォード大学のIBM 7090によつて行なわれた.海山はいづれも現在の地球磁場に比べて順方向に帯磁しているが,伏角はいづれも小さく,上向きの場合もあることが結論された.磁化は残留磁化が主成分と考えられるので,この結果にもとずき,古地磁気学的磁極を計算すると,大西洋北部に比較的よく集中する.これらの海山の生成年代は中生代と考えられるので,ここに得られた結果は,太平洋底の移動によるものかもしれない.但し,その可能性を確めるには,更に多くの海山について同様の研究を行うことが必要である.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"131256","nameIdentifierScheme":"WEKO"}],"names":[{"name":"上田, 誠也"}]},{"nameIdentifiers":[{"nameIdentifier":"131257","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Richards, Michael"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000033593","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":"Earthquake Research Institute and Geophysical Institute"},{"subitem_text_value":"Scripps Institution of Oceanography, University of California"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Uyeda, Seiya"}],"nameIdentifiers":[{"nameIdentifier":"131254","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Richards, Michael"}],"nameIdentifiers":[{"nameIdentifier":"131255","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":"ji0441011.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0441011.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/33593/files/ji0441011.pdf"},"version_id":"2ee1e332-b22f-4b72-b2e2-2e6a186f911c"}]},"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":"Magnetization of Four Pacific Seamounts near the Japanese Islands","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Magnetization of Four Pacific Seamounts near the Japanese Islands","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["4945","4946"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"33593","relation_version_is_last":true,"title":["Magnetization of Four Pacific Seamounts near the Japanese Islands"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:37:54.424211+00:00"}
