In the chondrite-normalized REE patterns, all samples yielded parallel concave tetrad patterns, and the mole ratios of Σ(REE+ Y) to Ca were calculated to be 2.5 to 3.4, all of which were obviously larger than the ideal value 2.0 of kimuraite. In addition, electron-probe microanalyzer (EPMA) was also applied to determine the compositions of our samples. Though only four rare earth elements (Y, La, Pr and Nd) were able to be measured, the mole ratios of Σ(REE+ Y) to Ca of thirty-two point analyses determined with EPMA were 2.1 to 3.3. Both analytical results demonstrated that our kimuraite samples might have excessive amount of REE. In the backscattered electron (BSE) images, besides dark kimuraite grains, the presence of another mineral with brighter BSE intensity along the cleavages of kimuraite grains was confirmed, and almost all analysis spots of EPMA failed to escape from the contamination of this mineral. The most possible candidate for this mineral is lanthanite, both for its close association with kimuraite and for its characteristic chemical composition. The compositions of our kimuraite samples, especially LREE, have been modified due to the presence of a small portion of lanthanite, but the concave tetrad pattern remains, as lanthanite seems to have a similar concave tetrad pattern like kimuraite.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/20542"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/joueps.60.101","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Dept. of Earth and Planetary Sciences, Nagoya University","subitem_publisher_language":"en"}]},"item_9_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_9_source_id_7":{"attribute_name":"ISSN（print）","attribute_value_mlt":[{"subitem_source_identifier":"0919-875X","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"JIAO, Wenfang","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"53525","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KAWABE, Iwao","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"53526","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KATO, Takenori","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"53527","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-02-21"}],"displaytype":"detail","filename":"60-3.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"60-3.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/18425/files/60-3.pdf"},"version_id":"34c0df30-6a04-4bd0-a097-0f3586c99217"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"rare earth elements","subitem_subject_scheme":"Other"},{"subitem_subject":"kimuraite","subitem_subject_scheme":"Other"},{"subitem_subject":"lanthanite","subitem_subject_scheme":"Other"},{"subitem_subject":"tetrad effect","subitem_subject_scheme":"Other"}]},"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":"Reexamination of kimuraite : the occurrence of lanthanite in the cleavages of kimuraite","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Reexamination of kimuraite : the occurrence of lanthanite in the cleavages of kimuraite","subitem_title_language":"en"}]},"item_type_id":"9","owner":"1","path":["1636"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2014-09-02"},"publish_date":"2014-09-02","publish_status":"0","recid":"18425","relation_version_is_last":true,"title":["Reexamination of kimuraite : the occurrence of lanthanite in the cleavages of kimuraite"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T04:07:10.778723+00:00"}
