Yamato (j) chondrite (H4) contains a metallic phase of 8.0wt% comprising kamacite of 5.3wt% Ni and smaller amounts of plessite and taenite, accompanied by non-magnetic metallic oxides. It seems very likely that the metallic oxides were in the form of hydroxides in the original state and were transformed to substituted magnetites by a heating. The metallic phase has been much oxidized by severe weathering. Yamato (k) chondrite (L5) contains a metallic phase of 8.6wt% comprising kamacite of 6.5wt% Ni and α_2-phase of (13-25)wt% Ni, suggesting that this chondrite was reheated to about 1000℃ and rapidly cooled to result in a production of α_2-phase. Yamato (m) chondrite (L5) contains a metallic phase of 8.3wt% comprising kamacite of 5.5wt% Ni and taenite, suggesting that this chondrite was almost equilibrated because of its very slow cooling and no appreciable effect of later metamorphism. Tables 3 and 4 give their basic magnetic properties, and Table 2 their chemical compositions.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","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"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1979-03-01"}],"displaytype":"detail","filename":"KJ00000011518.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"url":"https://nipr.repo.nii.ac.jp/record/972/files/KJ00000011518.pdf"},"version_id":"9bdba59a-223c-4b99-ab1f-3bf428e107f0"}]},"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":"Magnetic Properties of Yamato-7301(j), -7305(k) and -7304(m) Chondrites in Comparison with Their Mineralogical and Chemical Compositions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Magnetic Properties of Yamato-7301(j), -7305(k) and -7304(m) Chondrites in Comparison with Their Mineralogical and Chemical Compositions","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["366"],"pubdate":{"attribute_name":"公開日","attribute_value":"1979-03-01"},"publish_date":"1979-03-01","publish_status":"0","recid":"972","relation_version_is_last":true,"title":["Magnetic Properties of Yamato-7301(j), -7305(k) and -7304(m) Chondrites in Comparison with Their Mineralogical and Chemical Compositions"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:28:41.607789+00:00"}
