Characteristic textures due to alternating lamellae of Fe-rich and Fe-poor compositions have been found in the low-Ca pyroxenes in the chondrites irrespective of their chemical groups, H, L and LL. As far as the author knows, this is the first observation of such lamellae textures in the pyroxenes. These textures are common and remarkable in the higher subtypes of type 3 chondrites (L3.6,L3.7,LL3.8 and H3.9), while they are rare in lower subtypes (<3.5) and type 4 chondrites. These textures are considered to have been formed in the Fe-Mg homogenization process of the ordinary chondrites during metamorphism.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004454","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA10784627","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 Geology and Mineralogy, Faculty of Science, Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"Department of Geology and Mineralogy, Faculty of Science, Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"Department of Geology and Mineralogy, Faculty of Science, Kyoto University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1988-03-01"}],"displaytype":"detail","filename":"KJ00000036260.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000036260","url":"https://nipr.repo.nii.ac.jp/record/4454/files/KJ00000036260.pdf"},"version_id":"c4923548-b577-46c4-a8c6-f9b925de5b9f"}]},"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":"Fe-Mg heteorogeneity in the low-Ca pyroxenes during metamorphism of the ordinary chondrites","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Fe-Mg heteorogeneity in the low-Ca pyroxenes during metamorphism of the ordinary chondrites"}]},"item_type_id":"1","owner":"4","path":["585"],"pubdate":{"attribute_name":"公開日","attribute_value":"1988-03-01"},"publish_date":"1988-03-01","publish_status":"0","recid":"4454","relation_version_is_last":true,"title":["Fe-Mg heteorogeneity in the low-Ca pyroxenes during metamorphism of the ordinary chondrites"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:20:26.432537+00:00"}
