Essential information is required to support the assumed constitutive relation. Based on a comparison between present plate motion and formation of seismic anisotropy in the asthenosphere, the critical strain rate between linear and nonlinear deformation laws has a value of about 1～10×10^<-15>s^<-1>. This critical strain rate for formation of anisotropy due to plate motion has a larger value than typical strain rate of post glacial rebound (1～10×10^<-17>s^<-1>). Thus, the effective deformation mechanism in the asthenosphere for the post glacial rebound is linear rheology.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00009030","subitem_identifier_reg_type":"JaLC"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00181831","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00857289","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_21":{"attribute_name":"国際十進分類法","attribute_value_mlt":[{"subitem_subject":"550.34:551.2","subitem_subject_scheme":"UDC"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"国立極地研究所"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1998-03-01"}],"displaytype":"detail","filename":"KJ00000140392.pdf","filesize":[{"value":"384.2 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000140392","url":"https://nipr.repo.nii.ac.jp/record/9030/files/KJ00000140392.pdf"},"version_id":"b65039e2-973f-446e-8b70-c6c349a60600"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"オリビンの変形機構図に基く後氷期地殻変動に対するアセノスフェアの変形則の推定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"オリビンの変形機構図に基く後氷期地殻変動に対するアセノスフェアの変形則の推定"},{"subitem_title":"Estimation of asthenospheric deformation law for the post glacial rebound based on the deformation mechanism map of olivine","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1119"],"pubdate":{"attribute_name":"公開日","attribute_value":"1998-03-01"},"publish_date":"1998-03-01","publish_status":"0","recid":"9030","relation_version_is_last":true,"title":["オリビンの変形機構図に基く後氷期地殻変動に対するアセノスフェアの変形則の推定"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:15:12.293783+00:00"}
