The amounts of ^<24>Mg excess with respect to the terrestrial fractionation line were obtained for each chondrule. Barred olivine and glassy chondrules tend to have relatively large ^<24>Mg excess, whereas porphyritic and radial pyroxene chondrules have relatively small ^<24>Mg excess. The following three factors were taken into consideration in connection with the formation process of these chondrules in the Allende meteorite; (1) the temperature conditions at the formation of the chondrules, (2) the relative abundance of each chondrule type, (3) the amount of ^<24>Mg excess in each chondrule type. It is shown that chondrules formed at high temperature or by rapid cooling have relatively large ^<24>Mg excess and their relative abundance is small, whereas chondrules formed at low temperature or by slow cooling tend to have small ^<24>Mg excess and their relative abundance is large. A model of chondrule formation process in the early solar nebula is proposed to explain the relations between factors (1)-(3).","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004488","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":"College of General Education, Osaka University"},{"subitem_text_language":"en","subitem_text_value":"College of General Education, Osaka University"},{"subitem_text_language":"en","subitem_text_value":"College of General Education, Osaka University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1989-10-01"}],"displaytype":"detail","filename":"KJ00000036294.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000036294","url":"https://nipr.repo.nii.ac.jp/record/4488/files/KJ00000036294.pdf"},"version_id":"442b8868-16cb-425e-8808-0c2160e52a42"}]},"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":"The correlation of chondrule texture and magnesium isotope abundance in Allende meteorite","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The correlation of chondrule texture and magnesium isotope abundance in Allende meteorite"}]},"item_type_id":"1","owner":"4","path":["586"],"pubdate":{"attribute_name":"公開日","attribute_value":"1989-10-01"},"publish_date":"1989-10-01","publish_status":"0","recid":"4488","relation_version_is_last":true,"title":["The correlation of chondrule texture and magnesium isotope abundance in Allende meteorite"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:20:01.355898+00:00"}
