The R=100 mm spectrometer coupled with a large-sized PET crystal has the potential advantage of the count rate in the analysis of trace Pb. The disadvantage of the poor discrimination of U-Mz2 from Th-Mb was reduced by the correction. Effects of U-Mz1, Zr-Lg2.3, Pb-M4-02, Pb-AM5 and Pb-M5-03A on the background measurement were eliminated through selection of narrow interference-free windows. Reliability of the improved procedure was tested with zircon and xenotime in a sample of Tsubonosawa gneiss from Rikuzen-Takada, Iwate Prefecture. Zircon ages of 560-540 Ma and zoned xenotime ages of 460-440 Ma, 370-340 Ma and 230 Ma are compatible with isotopic ages and conventional CHIME ages. The improved CHIME dating on JXA-8530F FE-EPMA has shortened the measurement time to 1/3 of the conventional methods.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"日本電子製のFE-EPMA(JXA-8530F)を使って、CHIME年代測定の測定条件の最適化を行った。CHIME年代測定には、必須の測定元素であるTh、U、Pbの特性X線は、互いに干渉し合うため、干渉補正を行う必要がある。また、各元素のバックグラウンド測定位置の設定も測定精度に大きく影響を与える。本研究では、測定に使用する分析線(特性X線)の選択や、干渉する特性X線の強度を測定し干渉補正係数を求めて干渉補正を行った。バックグラウンドの測定位置は、スペクトルをとり、他の元素の特性X線の影響のない位置で設定した。今回作成した測定条件の測定時間は1試料あたり約15分である。この測定条件を用いて南部北上帯の壷ノ沢片麻岩のジルコンとゼノタイムを測定し、年代値を求めた。本試料が、後背地の火成作用を受けたのが、約5～20億年前、変成作用は約4.4億年前、さらに熱変成を受けたのが3.5億年前と2.5億年前と報告されており、今回の測定値も同程度の年代が得られた。従って、測定条件の妥当性が確認されたと判断できる。","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.26.126","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":"柴田, 健二","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"84292","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"清水, 麻由子","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"84293","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木, 和博","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"84294","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shibata, Kenji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"84295","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shimizu, Mayuko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"84296","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suzuki, Kazuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"84297","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","filename":"sibata2014.pdf","filesize":[{"value":"4.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"sibata2014.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/19980/files/sibata2014.pdf"},"version_id":"ec61c65c-130f-4ded-9b82-5eb45a0060e8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"CHIME年代測定","subitem_subject_scheme":"Other"},{"subitem_subject":"ジルコン","subitem_subject_scheme":"Other"},{"subitem_subject":"zircon","subitem_subject_scheme":"Other"},{"subitem_subject":"CHIME dating","subitem_subject_scheme":"Other"},{"subitem_subject":"Field Emission electron probe microanalysis (FE-EPMA)","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":"JAEA土岐地球年代学研究所のJEOL FE-EPMA-JXA-8530F-を用いたジルコンのCHIME年代測定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"JAEA土岐地球年代学研究所のJEOL FE-EPMA-JXA-8530F-を用いたジルコンのCHIME年代測定","subitem_title_language":"ja"}]},"item_type_id":"9","owner":"1","path":["1735"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-05-19"},"publish_date":"2015-05-19","publish_status":"0","recid":"19980","relation_version_is_last":true,"title":["JAEA土岐地球年代学研究所のJEOL FE-EPMA-JXA-8530F-を用いたジルコンのCHIME年代測定"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T04:09:06.445124+00:00"}
