The CI-normalized REE abundance patterns for Y-82162 are nearly flat (0.9-1.5×CI), but show small negative Ce anomalies. A small fraction of the chondrite shows a clear light/heavy REE fractionation. The REE abundance patterns of Y-86720 are also almost flat (1.4-1.9×CI) and show positive Eu anomalies. The degree of Eu anomaly seems to correlate with the absolute abundance of the REE. For the abundances of elements other than REE, Y-82162 shows enrichments of Fe and Mg and Y-86720 displays depletions of the relatively volatile elements K and Rb. From these results, the following conclusions are obtained : (1) Y-82162 may contain a high temperature component formed in the nebula. (2) Y-82162 is classified as a CI chondrite which has experienced thermal metamorphism. (3) Y-86720 is composed of a refractory-rich component and a refractory-poor component. (4) Y-86720 cannot be strictly classified into any group but is intermediate between CM and CO chondrites.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004510","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":"Department of Earth Sciences, Faculty of Science,Kobe University/ 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":"1990-10-01"}],"displaytype":"detail","filename":"KJ00000036316.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000036316","url":"https://nipr.repo.nii.ac.jp/record/4510/files/KJ00000036316.pdf"},"version_id":"010c662c-8f5b-415a-a7ca-580247de2239"}]},"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":"REE characteristics of Yamato-82162 and -86720 meteorites and their inference to classification","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"REE characteristics of Yamato-82162 and -86720 meteorites and their inference to classification"}]},"item_type_id":"1","owner":"4","path":["587"],"pubdate":{"attribute_name":"公開日","attribute_value":"1990-10-01"},"publish_date":"1990-10-01","publish_status":"0","recid":"4510","relation_version_is_last":true,"title":["REE characteristics of Yamato-82162 and -86720 meteorites and their inference to classification"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:19:47.573947+00:00"}
