The KF chondrule type is restricted to brecciated LL chondrites. The CP type is rare, and occurs mainly in carbonaceous chondrites. The SP and IP types are most abundant in all chondrites; the relative frequency of SP and IP types differs among brecciated LL type chondrites, ordinary chondrites (except for the brecciated LL type), and carbonaceous 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":"Department of Earth Sciences, Faculty of Science,Ibaraki University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1983-12-01"}],"displaytype":"detail","filename":"KJ00000012189.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"url":"https://nipr.repo.nii.ac.jp/record/1556/files/KJ00000012189.pdf"},"version_id":"8f498fa1-34e5-46e4-909f-c4b92e92f01d"}]},"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":"Major element chemical compositions and chemical types of chondrules in unequilibrated E, O, and C chondrites from Antarctica","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Major element chemical compositions and chemical types of chondrules in unequilibrated E, O, and C chondrites from Antarctica","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["384"],"pubdate":{"attribute_name":"公開日","attribute_value":"1983-12-01"},"publish_date":"1983-12-01","publish_status":"0","recid":"1556","relation_version_is_last":true,"title":["Major element chemical compositions and chemical types of chondrules in unequilibrated E, O, and C chondrites from Antarctica"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:47:33.335551+00:00"}
