FeO and Al_2O_3 contents of phyllosilicates in Y-8449 are richer than those in other CR chondrites. Fe-Ni metal in Y-8449 is classified into two types; one type has an exsolution texture indicating a slow cooling rate of the metal, and the other type has a massive texture free from exsolution texture. Massive Fe-Ni metal in Y-8449 is more homogeneous than that in the other CR chondrites. Groundmass glass and phenocrystic enstatite in Y-8449 chondrules have been replaced by phyllosilicate in the chondrule rims, and the aqueous alteration reaction that produced the phyllosilicate had possibly taken place in a nebula at low temperatures prior to accretion onto the parent body.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004668","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 polar Science, The Graduate University for Advanced Studies, National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"Department of Earth Sciences, Ibaraki 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":"KJ00000036474.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000036474","url":"https://nipr.repo.nii.ac.jp/record/4668/files/KJ00000036474.pdf"},"version_id":"182cda7c-51a6-4c84-a7b5-4915ee14dd3f"}]},"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":"Petrology of the Yamato-8449 CR chondrite","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Petrology of the Yamato-8449 CR chondrite"}]},"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":"4668","relation_version_is_last":true,"title":["Petrology of the Yamato-8449 CR chondrite"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:17:37.718979+00:00"}
