It is difficult to separate the organic metrials from calcium carbonate without any loss especially in the fossil shells, so the nitrogen analysis of the shell should be carried out with much calcium carbonate, not to remove it. The writer is successful in quantitative nitrogen analysis of the organic materials with much calcium carbonate (Fig. 1). Both the fossil and recent samples analysed are Anadara broughtoni, A. subcrenata, Ostrea gigas, Corbicula iaponica, C. leana, Meretrix lusoria, Mya japonica and Neverita didyma, which are shown in Table 1 with places of occurrence, absolute ages, and weight percents of nitrogen in the shell. In so far as the fossil shells of the Johmon shellmounds are concerned, it is concluded that nitrogen content of the shell indicates rapid diminishing in 2000 years and slow decreasing since then (Fig. 2).","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域地球社会基盤学系","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00061686","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"地学団体研究会 The Association for the Geological Collaboration in Japan"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.15080/agcjchikyukagaku.21.1_21","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://www.jstage.jst.go.jp/browse/agcjchikyukagaku/-char/ja"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.jstage.jst.go.jp/browse/agcjchikyukagaku/-char/ja","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.chidanken.jp/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.chidanken.jp/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://www.chidanken.jp/08_1.html"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.chidanken.jp/08_1.html","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © 地学団体研究会 The Association for the Geological Collaboration in Japan"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00141269","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0366-6611","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"2189-7212","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":"田崎, 和江"}],"nameIdentifiers":[{"nameIdentifier":"164","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"80211358","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=80211358"},{"nameIdentifier":"80211358","nameIdentifierScheme":"研究者番号","nameIdentifierURI":"https://nrid.nii.ac.jp/nrid/1000080211358"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-07-26"}],"displaytype":"detail","filename":"SC-PR-TAZAKI-K-21.pdf","filesize":[{"value":"534.3 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-TAZAKI-K-21.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/55411/files/SC-PR-TAZAKI-K-21.pdf"},"version_id":"803cbee6-8dab-4b07-9283-3d6feed77d83"}]},"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":"ミクロ・ケルダール法による縄文貝塚産の貝殻中の窒素定量","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ミクロ・ケルダール法による縄文貝塚産の貝殻中の窒素定量"},{"subitem_title":"Nitrogen analyses by micro-Kjeldahl method of the fossil shells yielded from the Johmon shell-mounds of the Kanto district, Japan","subitem_title_language":"en"}]},"item_type_id":"4","owner":"18","path":["937"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-07-26"},"publish_date":"2021-07-26","publish_status":"0","recid":"55411","relation_version_is_last":true,"title":["ミクロ・ケルダール法による縄文貝塚産の貝殻中の窒素定量"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-06-20T06:05:18.489158+00:00"}
