Although the observed ^<143>(Nd)/^<144>(Nd) ratios show some variations, ranging from 0.5126 to 0.5146,the data do not define an isochron. Rb-Sr measurements for mineral separates and whole rocks from the meteorites also do not yield a definite age information for these meteorites. The present results suggest that multiple young (possibly younger than 2.0 b. y.) metamorphic events may be responsible for the disturbance of the Rb-Sr and Sm-Nd systems of the meteorites.","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":"Department of Earth 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":"1979-12-01"}],"displaytype":"detail","filename":"KJ00000011601.pdf","filesize":[{"value":"860.4 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"url":"https://nipr.repo.nii.ac.jp/record/1057/files/KJ00000011601.pdf"},"version_id":"23c9087b-2560-450b-bff6-a4b70896f709"}]},"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 Isotopic Study on Four Yamato Diogenites-Sm-Nd and Rb-Sr Systematics-","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A Preliminary Isotopic Study on Four Yamato Diogenites-Sm-Nd and Rb-Sr Systematics-","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":"1057","relation_version_is_last":true,"title":["A Preliminary Isotopic Study on Four Yamato Diogenites-Sm-Nd and Rb-Sr Systematics-"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:27:36.252958+00:00"}
