This property now makes it possible to use the carbonate hydroxyapatite (CHa), an inorganic component of bone, for the 14C dating of cremated bones. Other chemical characteristics, such as Sr/Ca and δ88Sr, indicators of trophic levels and/or dietary preferences, are also expected to be preserved in cremated bones. This study was conducted to examine whether the CHa in cremated bones can provide accurate 14C dates and reliable information on diet. Cremated bone fragments from an urn at the Jisho-in Temple in Nara Prefecture, Japan were used as the sample. These bones are thought to be the remains of Jokei, a Buddhist monk (AD 1155–1213). The CHa in two fragments, which have high crystallinity, was determined to have a 14C date of 1040–1220 cal AD (±2σ), a date similar with the presumed age. The log(Sr/Ca) and δ88Sr values obtained from the bone CHa were –2.79 and from –0.140 to –0.125, respectively, values similar to those of herbivores (log(Sr/Ca)= –3.0～–2.5; Balter et al., 2002, δ88Sr =–0.30±0.17‰; Tütken et al., 2015). This finding is consistent with Jokei’s dietary custom of not eating meat. The results of this study demonstrate the effectiveness of using CHa in cremated bones for the 14C dating of bones and dietary analysis.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}, {"subitem_description": "最近の研究により、火葬されて有機成分が残存していない骨に対し、骨の無機成分である炭酸ヒドロキシアパタイト（Carbonate Hydroxyapatite: CHa）を用いた14C年代測定の有効性が実証された(Lanting et al., 2001; Zazzo et al., 2011）。CHaは、高温（＞600℃）で加熱されると結晶化が進み埋没後に続成作用の影響を受けにくくなることがその理由として挙げられる。そのため、結晶性の高いCHaを含む火葬骨は、生体由来の化学成分を保持でき、栄養段階の指標であるSr/Ca値やδ88Sr値などを分析することにより、14C年代だけでなく食性に関する情報も復元できることが期待できる。そこで、本研究では、仏教徒「貞慶」(AD1155-1213）の遺骨とされる火葬骨のSr/Ca値及びδ88Sr値の分析を行い、貞慶が菜食であったことを実証できるかどうかを検討した。結晶性の高い火葬骨のCHaから得られた14C年代値は貞慶の没年（1213年）と矛盾しない結果であった。さらに、log(Sr/Ca）値は－2.79、δ88Sr値は－0.14～－0.13であり、いずれも草食動物の値（log(Sr/Ca)=-3.0～－2.5; Balter et al., 2002、δ88Sr値＝－0.47～－0.13; Tütken et al., 2015））の範囲であった。この結果は、貞慶が菜食主義であったことを示すものであり、考古学的な見解と一致している。これらの結果から、高温で加熱され、結晶性が高い火葬骨CHaは、生体由来のSr/Ca値及びδ88Sr値を保持しており、年代に関する情報だけでなく生前の食習慣を探るのにも有効であることが明らかになった。", "subitem_description_language": "ja", "subitem_description_type": "Abstract"}]}, "item_9_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "本研究は、日本学術振興会科学研究費補助金挑戦的萌芽研究［骨の炭酸ヒドロキシアパタイトを用いた炭素14年代測定の試み」（代表者：南雅代、課題番号26560144）の助成を受けて行なわれました。", "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/nagubc.1.102", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "名古屋大学宇宙地球環境研究所年代測定研究部", "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": "78950", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "南, 雅代", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "78951", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "若木, 重行", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "78952", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "中村, 俊夫", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "78953", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Mukumoto, Hikari", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "78954", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Minami, Masayo", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "78955", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Wakaki, Shigeyuki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "78956", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakamura, Toshio", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "78957", "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": "2018-08-17"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "102-107_2016.pdf", "filesize": [{"value": "1.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 1200000.0, "url": {"label": "102-107_2016.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/26274/files/102-107_2016.pdf"}, "version_id": "4478f5dc-5233-4c9f-8143-5e10ec722338"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "14C dating", "subitem_subject_scheme": "Other"}, {"subitem_subject": "diet analysis", "subitem_subject_scheme": "Other"}, {"subitem_subject": "cremated bone", "subitem_subject_scheme": "Other"}, {"subitem_subject": "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": "火葬古人骨の炭酸ヒドロキシアパタイトを用いた年代測定と食性解析", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "火葬古人骨の炭酸ヒドロキシアパタイトを用いた年代測定と食性解析", "subitem_title_language": "ja"}]}, "item_type_id": "9", "owner": "1", "path": ["2104"], "permalink_uri": "https://doi.org/10.18999/nagubc.1.102", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2018-08-17"}, "publish_date": "2018-08-17", "publish_status": "0", "recid": "26274", "relation": {}, "relation_version_is_last": true, "title": ["火葬古人骨の炭酸ヒドロキシアパタイトを用いた年代測定と食性解析"], "weko_shared_id": -1}
