The samples consist predominantly of granitic complex or gneiss being older than 350-533m.y. in the shield region. The P-wave velocities for three orthogonal directions and the S-wave velocities for two orthogonal directions are measured to reveal anisotropy of the rocks. The velocities increase rapidly with increasing pressure at low pressures below 50-120 MPa due to crack closure. Whereas, the velocities increase linearly with increasing pressure at higher pressures than 50-120 MPa, and the velocities for each direction are nearly the same. A velocity model in the upper 20km of the crust is estimated from the laboratory data, assuming an appropriate temperature profile. The proposed model of P-wave velocity increasing gradually with depth is consistent with the upper crustal structure obtained by the explosion seismic experiments in the Ongul Islands and the Mizuho Plateau, East Antarctica.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Regional Center for Earthquake Prediction, Faculty of Science, Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"Regional Center for Earthquake Prediction, Faculty of Science, Kyoto University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1984-09-01"}],"displaytype":"detail","filename":"KJ00000012267.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012267","url":"https://nipr.repo.nii.ac.jp/record/1635/files/KJ00000012267.pdf"},"version_id":"26193478-bfc0-48bd-b6fa-c2bad12bbecc"}]},"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":"Velocities of P and S waves for drilling core rocks at Syowa Station, Antarctica","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Velocities of P and S waves for drilling core rocks at Syowa Station, Antarctica","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["387"],"pubdate":{"attribute_name":"公開日","attribute_value":"1984-09-01"},"publish_date":"1984-09-01","publish_status":"0","recid":"1635","relation_version_is_last":true,"title":["Velocities of P and S waves for drilling core rocks at Syowa Station, Antarctica"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:50:45.091985+00:00"}
