From the chemical composition and the microstructure, this iron meteorite can be classified as a reheated hexahedrite, i. e. a Ni-poor ataxite. An \"ablation zone\" about 2mm in thickness on the flat surface indicates an extensive reheating on entry into the earth's atmosphere although traces of the original single-crystal features remain. Within the matrix of kamacite (95% Fe and 5% Ni) composition, Fe-Ni phosphide (schribersite ; 75% Fe, 10% Ni and 15% P) grains are enveloped by high-P kamacite of α-phase (91% Fe, 7% Ni and 2% P). These structures suggest that this meteorite specimen was reheated to above 1000℃. The acicular grain structure of the kamacite matrix indicates a rapid cooling rate after the reheating. Both metallographic and magnetic analyses have consistently revealed the above-mentioned conclusion.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733470","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"U.S. Steel Corporation Research Laboratory"},{"subitem_text_language":"en","subitem_text_value":"Geophysical Institute, University of Tokyo"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1976-12-01"}],"displaytype":"detail","filename":"KJ00000011276.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000011276","url":"https://nipr.repo.nii.ac.jp/record/588/files/KJ00000011276.pdf"},"version_id":"12240fc2-920a-49a6-855f-f7aec08112ef"}]},"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":"Metallographic and Magentic Properties of a Yamato Iron Meteorite─Yamato-75-105","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Metallographic and Magentic Properties of a Yamato Iron Meteorite─Yamato-75-105","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["317"],"pubdate":{"attribute_name":"公開日","attribute_value":"1976-12-01"},"publish_date":"1976-12-01","publish_status":"0","recid":"588","relation_version_is_last":true,"title":["Metallographic and Magentic Properties of a Yamato Iron Meteorite─Yamato-75-105"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:13:00.547827+00:00"}
