Serpentine and brucite in serpentinite break down at high temperatures, and the rock sample consists of olivine, pyroxene, and H2O at～900℃ and 1 GPa. A Vs-Vp/Vs diagram is adapted to analyze the dehydration process from seismic velocity data. Employing Griineisen theory and third-order finite strain theory, we calculate elastic-wave velocities in a dry olivine-pyroxene solid. Then P- and S-velocities are estimated for various H2O fluid distributions (tubes, disks, and films) in the olivine-pyroxene-H2O system. At temperatures above complete dehydration of serpentinite, laboratory velocity data are reproduced using numerical calculations for triangular tubes of H2O fluid distribution. The results indicate that after dehydration is completed, elastic properties of serpentinite are estimated from those calculated for the olivine-pyroxene-H2O system.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"126159","nameIdentifierScheme":"WEKO"}],"names":[{"name":"佐藤, 博樹"}]},{"nameIdentifiers":[{"nameIdentifier":"126160","nameIdentifierScheme":"WEKO"}],"names":[{"name":"伊東, 和彦"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032604","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 and Space Science, Osaka University"},{"subitem_text_value":"Faculty of Business Administration, Southern Osaka University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sato, Hiroki"}],"nameIdentifiers":[{"nameIdentifier":"126157","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ito, Kazuhiko"}],"nameIdentifiers":[{"nameIdentifier":"126158","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":"ji0763003.pdf","filesize":[{"value":"834.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0763003.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32604/files/ji0763003.pdf"},"version_id":"76743be0-37d8-4e2e-be25-19f5f50c4f1d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"serpentinite","subitem_subject_scheme":"Other"},{"subitem_subject":"olivine-pryoxene-H2O system","subitem_subject_scheme":"Other"},{"subitem_subject":"Vs-Vp/Vs diagram","subitem_subject_scheme":"Other"},{"subitem_subject":"fluid distribution","subitem_subject_scheme":"Other"},{"subitem_subject":"dehydration process","subitem_subject_scheme":"Other"}]},"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":"H2O Fluid Distribution in Mantle Rock at 1 GPa : Constraints from Vs-Vp/Vs Diagram","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"H2O Fluid Distribution in Mantle Rock at 1 GPa : Constraints from Vs-Vp/Vs Diagram","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["4643","4644"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32604","relation_version_is_last":true,"title":["H2O Fluid Distribution in Mantle Rock at 1 GPa : Constraints from Vs-Vp/Vs Diagram"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:37.367737+00:00"}
