Meanwhile, recent studies have presented that carbonate hydroxyapatite (CHa), the inorganic fraction of the bone, can be used for 14C dating of cremated bone, though the CHa is easily contaminated by exogenous carbon and should be purified by chemical treatment. The purpose of this study is to test the reliability of 14C dating of CHa by using a cremated bone of known-age in Japan. The samples used were the cremated bone, which is considered to be remains of Jokei, a Buddhist monk (AD 1155-1213). We examined whether chemical treatment of the cremated bone with 0.1 M acetic acid for a short time of 1 hour is adequate for removal of secondary carbonate to obtain innate CHa for accurate 14C dating. The CHa in six fragments of the cremated bone showed 14C dates between 1155-1280 cal AD, which are similar with the supposed age. The result indicates the effectiveness of acetic acid treatment and the possibility of accurate 14C dating of CHa by the appropriate chemical treatment.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}, {"subitem_description": "骨の14C年代測定には、有機成分であるコラーゲンを利用するのが一般的である。しかし、コラーゲンが損失しているため、14C年代測定が困難な骨試料も少なくない。そのような骨試料、特に火葬骨に対して、近年、無機成分の炭酸ヒドロキシアパタイト(CHa)を用いた14C年代測定が試みられている。そこで、本研究では、年代既知の火葬骨に対して、実際に、CHaを用いて信頼性のある14C年代測定が可能かどうかの検証を行った。また、二次的な炭酸塩による汚染を除去するための低濃度短時間の酢酸処理の有効性についても評価を行った。用いた火葬骨試料は、奈良県三郷町の持聖院に所蔵されていた蔵骨器内の骨片である。この人骨は、平安時代末から鎌倉時代にかけて活躍した僧・貞慶（AD1155-1213）の遺骨であるとされている。年代測定の結果、本研究で使用した火葬骨6点から得られた14C年代は1155-1280cal ADという、貞慶の没年と2σの誤差範囲で一致する結果となった。一方、酢酸処理により発生したC02は現代に近い年代を示したことから、本研究で使用した火葬骨は、2次的な炭酸塩等の外来炭素の汚染があったものの、酢酸処理によって効果的に除去された結果、CHaの信頼性のある14C年代測定が可能であったことがわかった。また、真空下における、0.1Mの酢酸による1時間程度の酸処理の有効性も明らかになった。今後、より年代の古い試料や保存状態の異なる試料についても検討を行っていく予定である。", "subitem_description_language": "ja", "subitem_description_type": "Abstract"}]}, "item_9_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "名古屋大学年代測定総合研究センターシンポジウム報告", "subitem_description_language": "ja", "subitem_description_type": "Other"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/sumrua.26.96", "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", "subitem_publisher_language": "ja"}]}, "item_9_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "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": "椋本, ひかり", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "84256", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "南, 雅代", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "84257", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "中村, 俊夫", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "84258", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Mukumoto, Hikari", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "84259", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Minami, Masayo", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "84260", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakamura, Toshio", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "84261", "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", "download_preview_message": "", "file_order": 0, "filename": "mukumoto2014.pdf", "filesize": [{"value": "6.3 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 6300000.0, "url": {"label": "mukumoto2014.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/19975/files/mukumoto2014.pdf"}, "version_id": "47032ec2-3ac2-429d-87bb-c0fa89955537"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "radiocarbon dating", "subitem_subject_scheme": "Other"}, {"subitem_subject": "cremated bone", "subitem_subject_scheme": "Other"}, {"subitem_subject": "carbonate hydroxyapatite", "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": "火葬骨の炭酸ヒドロキシアパタイトを用いた14C年代測定の試み", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "火葬骨の炭酸ヒドロキシアパタイトを用いた14C年代測定の試み", "subitem_title_language": "ja"}]}, "item_type_id": "9", "owner": "1", "path": ["1735"], "permalink_uri": "https://doi.org/10.18999/sumrua.26.96", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2015-05-19"}, "publish_date": "2015-05-19", "publish_status": "0", "recid": "19975", "relation": {}, "relation_version_is_last": true, "title": ["火葬骨の炭酸ヒドロキシアパタイトを用いた14C年代測定の試み"], "weko_shared_id": -1}
