K-Ar ages of about 4.2Ga were obtained for Y-75302,Y-791827,Y-793575 and A-881988,while Y-82002 showed a slightly younger age of 3.9Ga. The Y-75302,Y-791827 and Y-82002 are enriched in solar light noble gases. Four meteorites Y-75302,Y-791827,Y-82002 and A-881988 have cosmic-ray exposure ages of about 20Ma, while the age of Y-793575 is about 7Ma. Based on the noble gas compositions and K-Ar ages, Y-75302 and Y-791827 are probably paired and Y-82002 may belong to this pair. Relatively high and variable ^<129>Xe/^<132>Xe ratios between 2-3.7 as well as enrichments of heavier Xe isotopes were observed in all R-chondrites.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00005946","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/Graduate School of Science and Technology, Kobe University/Graduate School of Science and Technology, Kobe University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1999-03-01"}],"displaytype":"detail","filename":"KJ00000040938.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000040938","url":"https://nipr.repo.nii.ac.jp/record/5946/files/KJ00000040938.pdf"},"version_id":"e6a06f26-99c5-430d-bc18-11575bc929a3"}]},"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 gases and K-Ar ages of five Rumuruti chondrites Yamato(Y)-75302, Y-791827, Y-793575, Y-82002, and Asuka-881988","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Noble gases and K-Ar ages of five Rumuruti chondrites Yamato(Y)-75302, Y-791827, Y-793575, Y-82002, and Asuka-881988"}]},"item_type_id":"1","owner":"4","path":["776"],"pubdate":{"attribute_name":"公開日","attribute_value":"1999-03-01"},"publish_date":"1999-03-01","publish_status":"0","recid":"5946","relation_version_is_last":true,"title":["Noble gases and K-Ar ages of five Rumuruti chondrites Yamato(Y)-75302, Y-791827, Y-793575, Y-82002, and Asuka-881988"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:08:19.905905+00:00"}
