Precious and bamboo corals differed from hump and stylasterina corals and giant clam in microspectroscopic spectra of the axes. The spectra of the former showed a particular type of calcite, whereas the later spectra indicated an aragonite. The spectrum of a deep-sea coral collected from off Midway Is. is different from that of other precious corals. Also that of a deep-sea coral collected from off Ogasawara Is., Japan was different from other corals in the spectra of sclerites. As a result of synchrotron infrared mapping analysis in the cross-section of precious coral axis, changes in the absorbance were observed at some wavenumbers. The cycle of fluctuation ranged from 109.23 to 147.17 μm. The fluctuation was considered to be an annual change. Therefore, the radial growth rate of precious coral axis was estimated to 0.22–0.35 mm year−1. This study indicates that synchrotron radiation-infrared spectroscopy analysis is effective to differentiate a genuine from a fake precious coral and to estimate the growth rates of precious corals. 宝石サンゴの持続的利用と国際取引の適切な管理技術を確立するために，マイクロビームを利用した赤外放射光による分析を行い，種及び産地の相違や成長速度について解析した．粉末試料を用いた分析の結果，宝石サンゴとバンブーコーラルの赤外吸収スペクトルはカルサイト特有であり，アラゴナイト特有の赤外吸収スペクトルを示すサンゴモドキ，ハマサンゴなどとは異なっていた．また，ミッドウェー産深海サンゴの赤外吸収スペクトルはほかの宝石サンゴとは異なっていた．さらに，共肉に含まれる骨片を分析した結果，小笠原産宝石サンゴはほかの宝石サンゴとは異なる赤外吸収スペクトルを示した．宝石サンゴ各種薄片のマッピング分析を行った結果，吸光極大に周期的な変動が見られ，その周期は109.23～147.17 μmの間隔であった．これは成長に伴う年変動であると考えられ，骨軸直径が肥大する成長速度は0.22～0.35 mm year－1と推定された．本研究により，放射光赤外分光法は宝石サンゴの同定及び真贋判定と成長速度推定に有効な手法であることが示された．","subitem_description_type":"Abstract"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本分析化学会 = The Japan Society for Analytical Chemistry"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2116/bunsekikagaku.63.593","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.jstage.jst.go.jp/browse/bunsekikagaku/-char/ja/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jsac.jp/","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © The Japan Society for Analytical Chemistry 日本分析化学会 2014"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00222633","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0525-1931","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"岩崎, 望"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"長谷川, 浩"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"鈴木, 淳"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森脇, 太郎"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"池本, 夕佳"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"SC-PR-HAEGAWA-H-593.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SC-PR-HAEGAWA-H-593.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/10819/files/SC-PR-HAEGAWA-H-593.pdf"},"version_id":"97368176-ec98-40a8-94f6-f4a110d27df6"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"赤外放射光を用いた宝石サンゴ骨軸の組織構造解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"赤外放射光を用いた宝石サンゴ骨軸の組織構造解析"},{"subitem_title":"Structural Analysis of Precious Coral Carbonate Layers Using Synchrotron Radiation-infrared Rays","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["937"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"10819","relation_version_is_last":true,"title":["赤外放射光を用いた宝石サンゴ骨軸の組織構造解析"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T01:36:20.697245+00:00"}
