The relatively low concentrations of primordial heavy noble gases (Kr and Xe) and the relatively high ^<129>Xe/^<132>Xe ratio (6.51±0.02) are similar to those found in previous studies of CK chondrites. The calculated cosmic-ray exposure age based on cosmogenic ^<21>Ne is 41Ma, and the K-Ar age is 2.1Ga. Based on calculated exposure ages and gas retention ages of Kobe and some other CK chondrites, it is likely that they have partially lost both radiogenic and cosmogenic He by solar heating during the time of exposure. Based on the ^<40>Ar retention age, we interpret that Kobe may also have experienced thermal events, possibly related to impacts about 2 billion years age.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00005998","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":"Department of Earth and Space Science, Graduate School of Science, Osaka University/Department of Earth and Space Science, Graduate School of Science, Osaka University/Department of Earth and Space Science, Graduate School of Science, Osaka University/Department of Earth and Planetary Sciences, Faculty of Science, 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":"2001-03-01"}],"displaytype":"detail","filename":"KJ00000040990.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000040990","url":"https://nipr.repo.nii.ac.jp/record/5998/files/KJ00000040990.pdf"},"version_id":"219da1d0-f5c8-4bf2-8ece-04a91fc40a8d"}]},"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":"A preliminary report on noble gases in the Kobe (CK) meteorite: A carbonaceous chondrite fell in Kobe City, Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A preliminary report on noble gases in the Kobe (CK) meteorite: A carbonaceous chondrite fell in Kobe City, Japan"}]},"item_type_id":"1","owner":"4","path":["778"],"pubdate":{"attribute_name":"公開日","attribute_value":"2001-03-01"},"publish_date":"2001-03-01","publish_status":"0","recid":"5998","relation_version_is_last":true,"title":["A preliminary report on noble gases in the Kobe (CK) meteorite: A carbonaceous chondrite fell in Kobe City, Japan"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:07:37.462503+00:00"}
