Orthopyroxene-bearing quartz-rich granulite, layering of which is indistinct to massive, is present as layers within the garnet felsic gneiss. Garnet-amphibole gneiss is present as layers in both the garnet-orthopyroxene gneiss and the garnet felsic gneiss. Orthopyroxene-bearing quartz-rich granulites contain coexisting orthopyroxene, sillimanite and quartz. The occurrence of sapphirine as inclusions in sillimanite implies that metamorphic conditions changed from the stability field of sapphirine+quartz to that of orthopyroxene+sillimanite+quartz. P-T conditions estimated using garnet-orthopyroxene geothermobarometry range from 920 to 1040℃ and 8.8 to 11.5 kbar. Garnet exsolution lamellae present in orthopyroxene from the garnet-orthopyroxene gneiss suggest that a precursor aluminous orthopyroxene was present during the ultrahigh-temperature stage. For the retrograde event, although chemical zoning of major element composition of garnet developed during cooling and reflects high-temperature diffusion, compositional zoning of more slowly diffusing elements, such as Ca, show a complicated pattern caused by partial resorbtion and overgrowth. Garnet rims in all rock types are intergrown with quartz and have relatively high grossular composition. Plagioclase in the garnet-orthopyroxene gneiss and garnet felsic gneiss show reverse zoning. Garnet-amphibole gneiss contains two amphiboles (gedrite and cummingtonite) with different fluorine contents; gedrite occurs as finely crystalline overgrowths surrounding cummingtonite, implying that the retrograde process after peak (ultrahigh-temperature) metamorphism was not simple cooling.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00003085","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":"Department of Natural Environmental Science, Kochi University/Department of Earth and Planetary Science, Kyushu University/Department of Geological Science, University of Maine/Department of Geology and Geophysics, Kline Geology Laboratory, Yale University/School of Geosciences, Edgeworth David Building, University of Sydney/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":"2001-10-01"}],"displaytype":"detail","filename":"KJ00000044203.pdf","filesize":[{"value":"2.9 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000044203","url":"https://nipr.repo.nii.ac.jp/record/3085/files/KJ00000044203.pdf"},"version_id":"f23af57b-4df3-4840-9ae6-83062eb80dcd"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"UHT metamorphic rocks","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"UHT metamorphism","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Christmas Point","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Napier Complex","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"East Antarctica","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":"High-grade metamorphic rocks from Christmas Point in the Napier Complex, East Antarctica","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"High-grade metamorphic rocks from Christmas Point 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":"3085","relation_version_is_last":true,"title":["High-grade metamorphic rocks from Christmas Point in the Napier Complex, East Antarctica"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:35:12.018497+00:00"}
