This study reports on how the relationship between magnetic susceptibility and sample thickness of obsidian contributes to identifying the source of obsidian tools. Obsidian samples from Shirataki, Hokkaido, Japan, were analyzed, focusing on those from the lava flows of Tokachi-Ishizawa (TI), Akaishiyama (AK), and Horoka-Yubetsu (HY). The sample thickness ranges from 2.74 to 20.84 mm and the magnetic susceptibility ranges from 6.1 × 10–5 to 4.2 × 10–4 SI for the TI lava, from 2.52 to 13.78 mm and 3.3 × 10–5 to 2.1 × 10–4 SI for the AK lava, and from 2.05 to 23.28 mm and from 1.9 × 10–4 to 7.3 × 10–4 SI for the HY lava, depending on the thickness of the sample wafer. The results revealed that obsidian from the HY lava demonstrated the highest value of magnetic susceptibility among the analyzed samples; thus, obsidian from the HY lava could be identified by this characteristic. Concurrently, heterogeneity in the magnetic susceptibility within a single lava flow was observed in the AK lava. These results could contribute to the identification of the source of obsidian tools and development of nondestructive techniques for measurement of magnetic susceptibility.\n\nKey words：magnetic susceptibility, obsidian, source identification, nondestructive analysis, rock texture","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2436-2387","subitem_source_identifier_type":"EISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐野, 恭平","creatorNameLang":"ja"},{"creatorName":"サノ, キョウヘイ","creatorNameLang":"ja-Kana"},{"creatorName":"SANO, Kyohei","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-04-04"}],"displaytype":"detail","filename":"資料.pdf","filesize":[{"value":"987.9 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"資料","url":"https://u-hyogo.repo.nii.ac.jp/record/6238/files/資料.pdf"},"version_id":"045b2220-b38d-4d75-a44d-89c5116afc86"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"産地同定のための白滝産黒曜石試料の帯磁率測定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"産地同定のための白滝産黒曜石試料の帯磁率測定","subitem_title_language":"ja"},{"subitem_title":"Measurement of magnetic susceptibility of obsidian from Shirataki, Hokkaido, Japan, to identify the source of obsidian tools","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"36","path":["1560"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-04-04"},"publish_date":"2021-04-04","publish_status":"0","recid":"6238","relation_version_is_last":true,"title":["産地同定のための白滝産黒曜石試料の帯磁率測定"],"weko_creator_id":"36","weko_shared_id":-1},"updated":"2023-12-13T04:52:14.711956+00:00"}
