Major element and carbon concentrations together with ^\u003c14\u003eC abundances were measured across weathering rinds of the sandstones. Specific depletion of calcium and carbon concentrations, and enrichment of iron concentration were observed in the weathering rinds for the both calcareous sandstones. The result indicates that calcareous phase in weathering rinds has been leached, and that ferrous ion has been accumulated in the rims by oxidization after migration under reducing subsurface during chemical weathering. It is noted that the Tatehama and Namiita sandstones have different behavior of migration for some elements such as calcium and magnesium in the extreme rims: a little enrichment and gradual depletion for the Tatehama and Namiita samplesラrespectively. The difference might be due to seawater-rock interaction because the Tatehama sample occurs near seashore lapped by wave and the Namiita sample does not. On the other hand, the both sandstones show the same ^\u003c14\u003eC accumulation behavior in weathering rinds. ^\u003c14\u003eC was not detected in the fresh fractions of the calcareous sandstones, due to ^\u003c14\u003eC-free (dead) carbon contained in a fresh Triassic limestone, while modem ^\u003c14\u003eC was detected in the weathering rinds. The modem ^\u003c14\u003eC could be originated from atmospheric CO2. From this study, ^\u003c14\u003eC is found to be a sensitive and general index of weathering of calcareous stones. Therefore, ^\u003c14\u003eC could be used as a sensitive index of concrete weathering.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "第21回名古屋大学年代測定総合研究センターシンポジウム平成20(2008)年度報告", "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.20.71", "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": "南, 雅代", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "82796", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "池田, 晃子", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "82797", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "吉田, 英一", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "82798", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "田中, 剛", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "82799", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Minami, Masayo", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "82800", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ikeda, Akiko", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "82801", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yoshida, Hidekazu", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "82802", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tanaka, Tsuyoshi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "82803", "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": "minami2008.pdf", "filesize": [{"value": "14.0 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 14000000.0, "url": {"label": "minami2008.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/12814/files/minami2008.pdf"}, "version_id": "d7b62707-3e78-44f2-a0d8-9a89fb15cd15"}]}, "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": "石灰質砂岩の炭素14 を指標とする風化評価 : コンクリート風化のナチュラルアナログ研究として", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "石灰質砂岩の炭素14 を指標とする風化評価 : コンクリート風化のナチュラルアナログ研究として", "subitem_title_language": "ja"}]}, "item_type_id": "9", "owner": "1", "path": ["1312"], "permalink_uri": "https://doi.org/10.18999/sumrua.20.71", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2011-04-28"}, "publish_date": "2011-04-28", "publish_status": "0", "recid": "12814", "relation": {}, "relation_version_is_last": true, "title": ["石灰質砂岩の炭素14 を指標とする風化評価 : コンクリート風化のナチュラルアナログ研究として"], "weko_shared_id": -1}
