Most chondrules in Y-691 are depleted in Fe, Mn, Cr, and Ca in comparison to the Y-691 whole rock composition, indicating that the depleted elements reside in sulfides and/or metals occurring outside chondrules. Compared with the solar system abundances, radial-Px, porphyritic and granular chondrules are depleted in all elements studied except for Si, but the Sinormalized contents of Al, Ti, Mg, and alkalies are similar to the Y-691 whole rock composition. On the other hand, barred-Ol-Px chondrules are enriched in refractory and moderately-refractory lithophiles (Al, Ti, Ca, and Mg) and poor in moderately-volatile elements (Mn, K, and Na). Some inclusions show chemical compositions similar to fine-grained CAI's and amoeboid olivine inclusions in carbonaceous chondrites.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004443","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, 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":"1988-03-01"}],"displaytype":"detail","filename":"KJ00000036249.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000036249","url":"https://nipr.repo.nii.ac.jp/record/4443/files/KJ00000036249.pdf"},"version_id":"2522429f-3013-4707-9f5e-ce3f23fa8491"}]},"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":"Petrochemical study of the Yamato-691 enstatite chondrite (EH3) I: Major element chemical compositions of chondrules and inclusions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Petrochemical study of the Yamato-691 enstatite chondrite (EH3) I: Major element chemical compositions of chondrules and inclusions"}]},"item_type_id":"1","owner":"4","path":["585"],"pubdate":{"attribute_name":"公開日","attribute_value":"1988-03-01"},"publish_date":"1988-03-01","publish_status":"0","recid":"4443","relation_version_is_last":true,"title":["Petrochemical study of the Yamato-691 enstatite chondrite (EH3) I: Major element chemical compositions of chondrules and inclusions"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:20:34.040268+00:00"}
