The Pacific sediment was divided chemically into leachate 1 (extracted by alkaline Na_2S_2O_4), leachate 2 (extracted by 0.17 M HCl) and residue. The leachate 1, leachate 2 and residue consist mainly of Mn oxide, carbonate fluorapatite (CFA), and detrital materials, respectively. The Mn oxide and CFA component are considered to provide information about REE composition of porewater. Assuming that Mn oxide and CFA in the sediment were in chemical equilibrium with the porewater in terms of REE, the REE composition (REE/Gd ratio) of the porewater in the sediment was estimated from the REE abundance of the leachate 1 and 2. The estimated REE pattern (REE/Gd ratio) of the porewater shows La depletion and Ce enrichment relative to the deep-seawater. The difference of REE composition between deep-seawater and porewater suggests that REE in pelagic sediment is mobilized during early diagenesis.", "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/2237/12208"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/bulnum.023.01", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "名古屋大学博物館", "subitem_publisher_language": "ja"}]}, "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": "13468286", "subitem_source_identifier_type": "PISSN"}]}, "item_9_text_14": {"attribute_name": "フォーマット", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "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": "TAKEBE, Masamichi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "31590", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "YAMAMOTO, Koshi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "31591", "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": "2018-02-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "bulnum_23_1.pdf", "filesize": [{"value": "1.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 1400000.0, "url": {"label": "bulnum_23_1.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/10388/files/bulnum_23_1.pdf"}, "version_id": "1a0ce338-c4f9-4b03-b99f-2b134d519fd6"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "REE composition", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Porewater", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Pelagic sediment", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Equilibrium calculation", "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": "Relative REE abundances of porewater in Pacific pelagic sediment: estimation by equilibrium calculations based on REE composition of Mn-oxide and apatite components", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Relative REE abundances of porewater in Pacific pelagic sediment: estimation by equilibrium calculations based on REE composition of Mn-oxide and apatite components", "subitem_title_language": "en"}]}, "item_type_id": "9", "owner": "1", "path": ["1144"], "permalink_uri": "https://doi.org/10.18999/bulnum.023.01", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2009-09-16"}, "publish_date": "2009-09-16", "publish_status": "0", "recid": "10388", "relation": {}, "relation_version_is_last": true, "title": ["Relative REE abundances of porewater in Pacific pelagic sediment: estimation by equilibrium calculations based on REE composition of Mn-oxide and apatite components"], "weko_shared_id": -1}
