The remove the foreign organic carbon and obtain reliable ^\u003c14\u003eC ages from bones, XAD-2 chromatography method was examined. The fossil bones used in the experiment were bone fragments collected from the Awazu submarine archeological site. The bone samples were demineralized with 4℃ 0.8N HCl and the acid-insoluble residue was concentrated by centrifugation and lyophilized. The demineralized bone powder was hydrolysed with 6N HCl at 110℃. Solids were removed by centrifugation before the filtered hydrolysate was passed through the XAD-2 resin to remove fulvic and humic acids. δ^\u003c13\u003eC values and ^\u003c14\u003eC ages for three fractions of decalcified bone powder, XAD-treated hydrolysate, and fulvic and humic acids in demineralization-hydrolysis-XAD treatment procedure. XAD-purified hydrolysates have more positive δ^\u003c13\u003eC values and older ^\u003c14\u003eC ages than gelatin collagen extracted by conventional method. The δ^\u003c13\u003eC values in fulvic and humic phases are significantly more negative than collagen fractions. Conventional collagen extraction method is sufficient for ^\u003c14\u003eC dating on well-preserved bones but insufficient on poorly-preserved bones, because the method does not totally remove exogenous organic carbon. XAD-2 resin is recommended for accurate ^\u003c14\u003eC and carbon isotope measurements.", "subitem_description_type": "Abstract"}]}, "item_9_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "タンデトロン加速器質量分析計業績報告 Summaries of Researches Using AMS 1996 (平成8)年度", "subitem_description_type": "Other"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/sumrua.8.247", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "名古屋大学年代測定資料研究センター 天然放射性元素測定小委員会"}]}, "item_9_relation_43": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ci.nii.ac.jp/naid/110000476047/", "subitem_relation_type_select": "URI"}}]}, "item_9_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "名古屋大学年代測定資料研究センター 天然放射性元素測定小委員会"}, {"subitem_rights": "本文データは学協会の許諾に基づきCiNiiから複製したものである"}]}, "item_9_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_text_14": {"attribute_name": "フォーマット", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "南, 雅代"}], "nameIdentifiers": [{"nameIdentifier": "80437", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Minami, Masayo"}], "nameIdentifiers": [{"nameIdentifier": "80438", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "中村, 俊夫"}], "nameIdentifiers": [{"nameIdentifier": "80439", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakamura, Toshio"}], "nameIdentifiers": [{"nameIdentifier": "80440", "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": "KJ00000187827.pdf", "filesize": [{"value": "403.4 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 403400.0, "url": {"label": "KJ00000187827.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/11477/files/KJ00000187827.pdf"}, "version_id": "52fdfe43-5e7e-4f63-8993-a656259ea8f4"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "fossil bone", "subitem_subject_scheme": "Other"}, {"subitem_subject": "collagen", "subitem_subject_scheme": "Other"}, {"subitem_subject": "hydrolysis", "subitem_subject_scheme": "Other"}, {"subitem_subject": "XAD-2resin", "subitem_subject_scheme": "Other"}, {"subitem_subject": "14C age", "subitem_subject_scheme": "Other"}, {"subitem_subject": "δ^\u003c13\u003eC value Awazu submarine archeological site", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "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": "骨化石試料に対する信頼度の高い\u003c14\u003e^C年代, 炭素同位体比測定の試み", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "骨化石試料に対する信頼度の高い\u003c14\u003e^C年代, 炭素同位体比測定の試み"}]}, "item_type_id": "9", "owner": "1", "path": ["1227"], "permalink_uri": "https://doi.org/10.18999/sumrua.8.247", "pubdate": {"attribute_name": "公開日", "attribute_value": "2010-05-18"}, "publish_date": "2010-05-18", "publish_status": "0", "recid": "11477", "relation": {}, "relation_version_is_last": true, "title": ["骨化石試料に対する信頼度の高い\u003c14\u003e^C年代, 炭素同位体比測定の試み"], "weko_shared_id": null}
