Cosmic-ray exposure ages calculated from cosmogenic ^(21)Ne were 20.5, 32.3 and 29.7m.y. for A-880702, A-880761 and A-881388, respectively. Combining the exposure ages with ^(81)Kr-Kr apparent exposure ages, terrestrial ages of 0.20, 0.22 and 0.23m.y. were derived for A-880702, A-880761 and A-881388, respectively. ^(244)Pu-Xe ages based on fissiogenic Xe isotopes showed that the Asuka eucrites began Xe retention at around the crystallization age of Angra dos Reis. Among the Asuka eucrites, A-880702 is about 20m.y. older than the others. From the noble gas and age data described above, we conclude that A-880761 and A-881388 are paired, but A-880702 is not.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00006074","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11182426","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":"Laboratory for Earthquake Chemistry, Graduate School of Science, University of Tokyo/Laboratory for Earthquake Chemistry, Graduate School of Science, University of Tokyo"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2005-03-01"}],"displaytype":"detail","filename":"KJ00002499481.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002499481","url":"https://nipr.repo.nii.ac.jp/record/6074/files/KJ00002499481.pdf"},"version_id":"7917c15c-fc32-4377-98cc-470dd70f26ef"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"eucrite, noble gases, pairing, cosmic-ray exposure ages, 244Pu-Xe ages","subitem_subject_language":"en","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":"Noble gas and chronological study of Asuka eucrites: A-880761 and A-881388 are paired, but A-880702 is not","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Noble gas and chronological study of Asuka eucrites: A-880761 and A-881388 are paired, but A-880702 is not"}]},"item_type_id":"1","owner":"4","path":["782"],"pubdate":{"attribute_name":"公開日","attribute_value":"2005-03-01"},"publish_date":"2005-03-01","publish_status":"0","recid":"6074","relation_version_is_last":true,"title":["Noble gas and chronological study of Asuka eucrites: A-880761 and A-881388 are paired, but A-880702 is not"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:06:35.679045+00:00"}
