This observation revealed that the apparent surface velocity of P-waves refracted from the lower-lithosphere was observed as 8.4 km/sec in the epicentral distances of 7°-9°. The true velocities at their turning points (depth level 60-100km) were about 8.3km/sec. The existence of 8.4-8.5km/sec (apparent velocity) layers at the top of the lower-lithosphere appears to be a general feature not only beneath the continental shield regions but also beneath the old ocean basins. Such a P-wave velocity supports the garnet-pyrolite model for the mineralogical composition of the lower-lithosphere.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"128078","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nagumo, Shozaburo"}]},{"nameIdentifiers":[{"nameIdentifier":"128079","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ouchi, Toru"}]},{"nameIdentifiers":[{"nameIdentifier":"128080","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kasahara, Junzo"}]},{"nameIdentifiers":[{"nameIdentifier":"128081","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Koresawa, Sadayuki"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032858","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":"東京大学地震研究所"},{"subitem_text_value":"神戸大学理学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"南雲, 昭三郎"}],"nameIdentifiers":[{"nameIdentifier":"128074","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大内, 徹"}],"nameIdentifiers":[{"nameIdentifier":"128075","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"笠原, 順三"}],"nameIdentifiers":[{"nameIdentifier":"128076","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"是澤, 定之"}],"nameIdentifiers":[{"nameIdentifier":"128077","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":"ji0613001.pdf","filesize":[{"value":"906.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0613001.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32858/files/ji0613001.pdf"},"version_id":"3b0d49df-2c60-437b-a4e5-45f608ded907"}]},"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":"P-wave Velocity in the Lower-Lithosphere in the Western Northwest Pacific Basin Observed by an Ocean-bottom Seismometer Long Range Array","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"P-wave Velocity in the Lower-Lithosphere in the Western Northwest Pacific Basin Observed by an Ocean-bottom Seismometer Long Range Array","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["4771","4772"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32858","relation_version_is_last":true,"title":["P-wave Velocity in the Lower-Lithosphere in the Western Northwest Pacific Basin Observed by an Ocean-bottom Seismometer Long Range Array"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:47.280254+00:00"}
