The purpose of this study is to examine how the obsidian was distributed and used in Honshu. First, the author gathered and organized the results of the identification of obsidian sources based on X-ray fluorescence analysis, especially estimated to be from Kozushima island. The target sites for this step are dated to the early Upper Paleolithic period (cultural phase BBII~BBVII, ca. 30,000-38,500 cal BP). Secondly, using spatial analysis by GIS (Geographic Information System), this study analyzed geographic centers of 31 sites, which emerged as a result of the recognized information and compared them based on time or through cases distinguished by the number or weight of obsidian. Based on the results, obsidian from Kozushima was found to have a strong relationship with the side-blowed flake technology, which were used more administratively and carefully than obsidian from Izu-Hakone area. In addition, the distribution ranges were clearly different between phases I and II even in the early Upper Paleolithic period.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"162436","nameIdentifierScheme":"WEKO"}],"names":[{"name":"AIKAWA, Jo"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00079709","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院人文社会系研究科・文学部考古学研究室"}]},"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":"AA11190220 ","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18803784","subitem_source_identifier_type":"ISSN"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Department of Archaeology Faculty of Letters, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"相川, 壌"}],"nameIdentifiers":[{"nameIdentifier":"162435","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":"2020-10-12"}],"displaytype":"detail","filename":"kouko3301.pdf","filesize":[{"value":"12.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kouko3301.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/54593/files/kouko3301.pdf"},"version_id":"b00105a6-b911-4616-871f-8461423d3901"}]},"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":"後期旧石器時代前半期における神津島産黒曜石の利用とその広がり : 原産地推定結果の広域的再集成から","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"後期旧石器時代前半期における神津島産黒曜石の利用とその広がり : 原産地推定結果の広域的再集成から"}]},"item_type_id":"4","owner":"1","path":["8478","8477"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-10-12"},"publish_date":"2020-10-12","publish_status":"0","recid":"54593","relation_version_is_last":true,"title":["後期旧石器時代前半期における神津島産黒曜石の利用とその広がり : 原産地推定結果の広域的再集成から"],"weko_creator_id":"1","weko_shared_id":2},"updated":"2022-12-19T04:32:13.353192+00:00"}
