Cross-sections of 132 objects, mostly from the Warring States Period, were studied and were classifies as metallic copper (Cu) and bronze (Cu-Sn) objects. Based on chemical compositions, Cu-objects were divided into 3 groups, such as almost Cu-metal, Cu with Pb + Arsenic (As), and Cu with Pb + As + antinomy (Sb). Likewise, bronze objects were divided into 4 groups, such as bronze with Pb, bronze with Pb + As, bronze with Pb + Sb, and bronze with Pb + As + Sb. Leaded bronze are separated in low (<3 wt.％) and high-Pb (up to 45 wt.％) groups. Sn ratio (Sn/[Cu+Sn]) in bronzes range from low (2％) to high (20％) Sn. Most of objects contain a few amounts of miner elements, such as iron (Fe), silver (Ag), cobalt (Co) and some Cu and/or Fe sulfides. There elements might be originated from metallic ores and low qualities of parent metals. Since As and Sb are characteristic elements in metallic objects of “the eastern Eurasian steppe”, it might be suggested such origin. Pb is a fusion agent to lowering of melting temperature of molten Cu and bronze. In comparison to the Pb contents in Anyang (Yinxu) Bronzes in the Academia Sinica collection (many are < 2wt％ Pb), Pb contents are extremely high in high-Pb bronze group. Such objects with various Sn-ratios with As and Sb might suggest recycling work of metal in ancient societies. Thus, chemical signature might not always be related to their origins of ore minerals in the objects.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"160364","nameIdentifierScheme":"WEKO"}],"names":[{"name":"IIZUKA, Yoshiyuki"}]},{"nameIdentifiers":[{"nameIdentifier":"160365","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HIRASE, Takao"}]},{"nameIdentifiers":[{"nameIdentifier":"160366","nameIdentifierScheme":"WEKO"}],"names":[{"name":"WANG, Yu-Shiang"}]},{"nameIdentifiers":[{"nameIdentifier":"160367","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SUZUKI, Mai"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00079136","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学東洋文化研究所"}]},"item_4_select_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00170926","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05638089","subitem_source_identifier_type":"ISSN"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Institute for Advanced Studies on Asia, The University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"中央研究院地球科学研究所"},{"subitem_text_value":"東京大学東洋文化研究所"},{"subitem_text_value":"中央研究院地球科学研究所"},{"subitem_text_value":"学習院大学東洋文化研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"飯塚, 義之"}],"nameIdentifiers":[{"nameIdentifier":"160360","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"平㔟（平勢）, 隆郎"}],"nameIdentifiers":[{"nameIdentifier":"160361","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"王, 宇祥"}],"nameIdentifiers":[{"nameIdentifier":"160362","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木, 舞"}],"nameIdentifiers":[{"nameIdentifier":"160363","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":"2020-04-10"}],"displaytype":"detail","filename":"ioc177003.pdf","filesize":[{"value":"58.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ioc177003.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/54019/files/ioc177003.pdf"},"version_id":"40844092-2da7-4964-b935-bc28237417ba"}]},"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":"東方文化学院（東京研究所）旧蔵戦国貨幣の金相学的再検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"東方文化学院（東京研究所）旧蔵戦国貨幣の金相学的再検討"}]},"item_type_id":"4","owner":"1","path":["8373","8374"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-04-13"},"publish_date":"2020-04-13","publish_status":"0","recid":"54019","relation_version_is_last":true,"title":["東方文化学院（東京研究所）旧蔵戦国貨幣の金相学的再検討"],"weko_creator_id":"1","weko_shared_id":2},"updated":"2022-12-19T04:32:37.885046+00:00"}
