The ^<53>(Mn) activities in these meteorites are all close to the saturation value which indicates exposure ages longer than 4 million years. The effect of weathering on the ^<53>(Mn) content was investigated in two oxidized meteorites, Yamato-7301 and Allan Hills-76008. These meteorites have been shown by our previous works to have experienced two-stage irradiations in space. The ^<53>(Mn) contents in the metal phases agreed within the error with those in the non-magnetic phases which contained high concentrations of oxidized Fe of metallic origin, and also with the values for bulk samples previously reported. The effect is clearly shown of minor significance. The data on spallogenic nuclides so far obtained for these two meteorites are summarized and discussed in light of a two-stage irradiation history.","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":"Institute for Nuclear Study, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Department of Chemistry, B-017, University of California"},{"subitem_text_language":"en","subitem_text_value":"The Institute for Solid State Physics, 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":"1979-12-01"}],"displaytype":"detail","filename":"KJ00000011602.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000011602","url":"https://nipr.repo.nii.ac.jp/record/1058/files/KJ00000011602.pdf"},"version_id":"42f5a8dd-c7b3-46f3-92d0-6a6ba62b6272"}]},"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":"Cosmogenic 53Mn in Antarctic Meteorites and Their Exposure History","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Cosmogenic 53Mn in Antarctic Meteorites and Their Exposure History","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["369"],"pubdate":{"attribute_name":"公開日","attribute_value":"1979-12-01"},"publish_date":"1979-12-01","publish_status":"0","recid":"1058","relation_version_is_last":true,"title":["Cosmogenic 53Mn in Antarctic Meteorites and Their Exposure History"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:04:42.629692+00:00"}
