The starting material was obtained from an ultrahigh-temperature (UHT) garnet-orthopyroxene-bearing quartzo-feldspathic gneiss in the Mt. Riiser-Larsen of the Napier Complex, East Antarctica. This UHT gneiss is considered to be equilibrated at metamorphic conditions >1070℃. The mineral assemblages in the run products at 1000℃ and 1100℃ are the same as those of the starting material. K_2O content in K-feldspar lamellae of antiperthite decreases with temperature. Granitic glass (<10 vol%) was detected along boundaries between lamella-free plagioclase and quartz grains in the run at 1150℃. The experimental results indicate that the homogenization temperature of this antiperthite lies <1150℃ at 1.0 Gpa. It is consistent with the estimated temperature from feldspar geothermometry. Major element composition of the glass at 1150℃ shows the molecular Al_2O_3/(Na_2O+K_2O+CaO) ratio (A.S.I.: aluminum saturation index) = 1.08 and high Na_2O+K_2O contents (8.1 wt%) relative to low CaO (1.3 wt%), which is comparable to the chemical features of A-type granite or leucogranite. This may imply that some genetic links might exist between UHT metamorphism and A-type granite magmatism in the Napier Complex.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00003084","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":"AA1130866X","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"},{"subitem_text_language":"en","subitem_text_value":"Department of Environmental Sciences, Yokohama National University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2001-10-01"}],"displaytype":"detail","filename":"KJ00000044202.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000044202","url":"https://nipr.repo.nii.ac.jp/record/3084/files/KJ00000044202.pdf"},"version_id":"e6a38494-a7c3-4a1e-bd1a-eef97d723b2f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"dry condition","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"feldspar","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"melting experiment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Napier Complex","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ultrahigh-temperature (UHT) metamorphism","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Experimental constraints on partial melting under UHT and dry conditions of quartzo-feldspathic rock in the Napier Complex, East Antarctica","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Experimental constraints on partial melting under UHT and dry conditions of quartzo-feldspathic rock in the Napier Complex, East Antarctica"}]},"item_type_id":"1","owner":"4","path":["439"],"pubdate":{"attribute_name":"公開日","attribute_value":"2001-10-01"},"publish_date":"2001-10-01","publish_status":"0","recid":"3084","relation_version_is_last":true,"title":["Experimental constraints on partial melting under UHT and dry conditions of quartzo-feldspathic rock in the Napier Complex, East Antarctica"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:35:13.030914+00:00"}
