The CI-chondrite normalized REE patterns for five chondrules are almost flat but show more or less anomalies of Ce, Eu and Yb. The same REE features are observed in some Allende porphyritic chondrules suggesting that one of the refractory lithophile precursors of CO and CV chondrules had an unfractionated REE pattern with minor irregularities of Ce, Eu and Yb. The coarse-grained Ca, Al-rich inclusion, which may be assigned to Type B1,exhibits a Group III REE pattern with a large negative Yb anomaly. This is inconsistent with elemental volatilities since Yb is more depleted than Eu, suggesting that a Eu-enriched component may have been added to normal Group III CAI prior to melting the inclusion precursor. The REE abundance of bulk Felix is unfractionated (1.6-1.7×CI) with ∿20% excess of Ce. Anomalies of Ce and/or Yb, commonly observed in carbonaceous chondrites, can be understood as reflecting gas/solid (or liquid) fractionation processes of chondrule precursors as well as those of Ca, Al-rich inclusions.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004458","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 Science of Material Differentiation, Graduate School of Science and Technology, Kobe University/Department of Science of Material Differentiation, Graduate School of Science and Technology, 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":"1988-03-01"}],"displaytype":"detail","filename":"KJ00000036264.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000036264","url":"https://nipr.repo.nii.ac.jp/record/4458/files/KJ00000036264.pdf"},"version_id":"0b9cc11f-75da-400a-bd04-e378f9eb1ea0"}]},"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":"Rare earth elements in chondrules from the Felix (CO3) chondrite: Comparison with Allende (CV) chondrules","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Rare earth elements in chondrules from the Felix (CO3) chondrite: Comparison with Allende (CV) chondrules"}]},"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":"4458","relation_version_is_last":true,"title":["Rare earth elements in chondrules from the Felix (CO3) chondrite: Comparison with Allende (CV) chondrules"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:20:23.069888+00:00"}
