Concordant concentrations of ^3He and ^<21>Ne have been obtained on both samples (Bern and Misasa). The concentration of cosmogenic ^<38>Ar is twice as high in the Bern as in the Misasa sample. The ^3He, ^<21>Ne and ^<38>Ar data for both samples yield an average cosmic-ray exposure age of 5.8±2.0Ma. This age indicates that Yamato-74357 belongs to the lodranite group, which probably originates from a common break-up event about 5Ma ago. Radiogenic ^4He and ^<40>Ar concentrations in the Bern sample are higher than those in the Misasa sample by more than a factor of two, suggesting that minerals enriched in U, Th and K are enriched in the finer grained fraction. The isotopic compositions of Kr and Xe are identical to those of the terrestrial atmosphere, except for the ^<129>Xe abundance. The small ^<129>Xe excess (^<129>Xe/^<132>Xe=1.15±0.04) is presumably due to the early formation of this meteorite.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004684","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":"AA10784627","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":"Institute for Study of the Earth's Interior, Okayama University/Physikalisches Institute, University of Bern/Physikalisches Institute, University of Bern/Department of Earth and Planetary Physics, University of Tokyo/Institute of Geochemistry, University of Vienna/Department of Earth and Planetary Sciences,Faculty of Science, Kyushu University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1995-03-01"}],"displaytype":"detail","filename":"KJ00000036490.pdf","filesize":[{"value":"871.1 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000036490","url":"https://nipr.repo.nii.ac.jp/record/4684/files/KJ00000036490.pdf"},"version_id":"a4e5d636-2131-4504-ae62-b69fb0706be6"}]},"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, chemical composition, and cosmic-ray exposure age of the Yamato-74357 lodranite","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Noble gases, chemical composition, and cosmic-ray exposure age of the Yamato-74357 lodranite"}]},"item_type_id":"1","owner":"4","path":["592"],"pubdate":{"attribute_name":"公開日","attribute_value":"1995-03-01"},"publish_date":"1995-03-01","publish_status":"0","recid":"4684","relation_version_is_last":true,"title":["Noble gases, chemical composition, and cosmic-ray exposure age of the Yamato-74357 lodranite"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:17:23.021746+00:00"}
