Its content in clays reflects the sedimentary condition in which the clays were formed. On the other hand, ⁹Be, the stable isotope of beryllium, is contained in diverse rocks. The content of ⁹Be reflects the geology of the source site where the clay is originated. Thus, the pair of ¹⁰Be-⁹Be provides a possible means of discriminating the provenance of the pottery from the others.\nDistribution of the ⁹Be and ¹⁰Be contents in the Kawarada pottery samples indicates an existence of a large group, which consists of ca. 70% of the pottery investigated. It is found that almost all samples of this group are classified into 5 major and sub-major groups of the total 11 mineralogical groups given by Mizusawa in this report. It is noted that all the samples with typologically non-local origin and 5 out of 6 minor mineralogical groups given by Mizusawa are positioned outside of the main grouping of beryllium. These facts should be useful in discussing the way of pottery production such as clay sources and the possible addition of minerals, and their mutual transportation between archaeological sites in the Middle Jomon Period.","subitem_description_type":"Abstract"}]},"item_10002_heading_23":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_banner_headline":"[共同研究] 歴史資料の多角化と総合化","subitem_heading_language":"ja"},{"subitem_heading_banner_headline":"[Collaborative Research] Diversification and Integration of Historical Materials Analysis","subitem_heading_language":"en"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15024/00001311","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立歴史民俗博物館","subitem_publisher_language":"ja"}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"第120集 収録論文 タイトルリスト"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.rekihaku.ac.jp/outline/publication/ronbun/ronbun5/index.html#no120","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00377607","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-7400","subitem_source_identifier_type":"PISSN"}]},"item_10002_version_type_20":{"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":"坂本, 稔","creatorNameLang":"ja"},{"creatorName":"サカモト, ミノル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3365","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"今村, 峯雄","creatorNameLang":"ja"},{"creatorName":"イマムラ, ミネオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3366","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakamoto, Minoru","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"3367","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Imamura, Mineo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"3368","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":"2016-04-01"}],"displaytype":"detail","filename":"kenkyuhokoku_120_13.pdf","filesize":[{"value":"557.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kenkyuhokoku_120_13.pdf","url":"https://rekihaku.repo.nii.ac.jp/record/1328/files/kenkyuhokoku_120_13.pdf"},"version_id":"26441af7-27bc-47a0-8044-aed6d59fa8a1"}]},"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":"ベリリウム同位体による縄文土器胎土のグルーピング : 長野県川原田遺跡出土の土器について（第1部　縄文土器の生産と流通 / 土器胎土の自然科学的分析）","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ベリリウム同位体による縄文土器胎土のグルーピング : 長野県川原田遺跡出土の土器について（第1部　縄文土器の生産と流通 / 土器胎土の自然科学的分析）","subitem_title_language":"ja"},{"subitem_title":"Beryllium Isotopes Study of Middle Jomon pottery from the Kawarada Site (Part I: The Production and Distribution of Jomon Pottery / Scientific Analysis of Jomon Pottery Materials)","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"3","path":["146"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-04-01"},"publish_date":"2016-04-01","publish_status":"0","recid":"1328","relation_version_is_last":true,"title":["ベリリウム同位体による縄文土器胎土のグルーピング : 長野県川原田遺跡出土の土器について（第1部　縄文土器の生産と流通 / 土器胎土の自然科学的分析）"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-10-12T04:38:00.473653+00:00"}
