The saturation magnetization (I_s) of 3 ureilites ranges 2.2-6.4emu/gm while I_s is smaller than 0.53emu/gm for 7 diogenites, 6 eucrites and 1 howardite. By the thermomagnetic analysis, the I_s value of each achondrite is resolved into the saturation magnetization of kamacite, I_s (α), that of plessite, I_s (α+γ), that of taenite I_s (γ), and that of shreibersite, I_s (Ph). Results show that I_s (α)/I_s ≲ 0.40 for diogenites, whereas 1 ≳ I_s (α)/I_s ≳ 0.79 for eucrites and howardites, which indicate that Ni-content in metallic nickel-irons in diogenites is definitely larger than that in eucrites and howardites. On an I_s (α)/I_s versus I_s diagram, therefore, the three groups of achondrite are well separately grouped, just as so in the magnetic classification of chondrites.","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":"1980-12-01"}],"displaytype":"detail","filename":"KJ00000011628.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"url":"https://nipr.repo.nii.ac.jp/record/1102/files/KJ00000011628.pdf"},"version_id":"1d1002a5-18f5-4381-aee1-4a24061a751b"}]},"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 Classification of Antarctic Achondrites","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Magnetic Classification of Antarctic Achondrites","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["371"],"pubdate":{"attribute_name":"公開日","attribute_value":"1980-12-01"},"publish_date":"1980-12-01","publish_status":"0","recid":"1102","relation_version_is_last":true,"title":["Magnetic Classification of Antarctic Achondrites"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:27:05.682440+00:00"}
