This schist consists of porphyroblastic garnet, the core of which is compositionally homogeneous pyrope-almandine (X_<Mg>=Mg/(Fe+Mg)&cong;0.50) surrounded by an almandine rim (X_<Mg>&cong;0.27), biotite (X_<Mg>=0.70-0.73), plagioclase (An_<75-87>), spinel (X_<Mg>=0.26-0.36), corundum, rutile and zircon. In addition, individual garnet porphyroblasts enclose different mineral associations in the magnesian cores as follows : (A) sapphirine (X_<Mg>=0.75-0.85), commonly with kyanite, and, locally, with spinel (X_<Mg>=0.50-0.68), (B) kyanite only, and (C) gedrite (X_<Mg>=0.75-0.78)+quartz aggregates. The mineral associations sapphirine+kyanite±spinel and gedrite+quartz±kyanite are inferred to be relict assemblages of the prograde P-T path, and the magnesian garnet cores to have been homogenized during the granulite-facies event. Differences in the associations are presumed to have resulted from pre-metamorphic chemical heterogeneity in the precursor to the biotitic schist. These mineral associations suggest a clockwise prograde P-T trajectory entirely within the kyanite field; the assemblage sapphirine+kyanite might have been stable as T approached 700℃ constraining P to be at least 8 kbar. Further increase in temperature was accompanied by a small decrease in P to the 7-8 kbar (at T=760-800℃) estimated for peak conditions in the granulite-facies by M. ASAMI et al. (Proc. NIPR Symp. Antarct. Geosci., 6,57,1993). The relict sapphirine-kyanite assemblages in the Sør Rondane Mountains are similar to those reported from the Luzow-Holm Bay complex, Antarctica, and the Highland Complex, Sri Lanka (e.g. Y. OGO et al. : Recent Progress in Antarctic Earth Science, ed. by Y. Yoshida et al. Tokyo, Terra Sci. Publ., 75,1992), suggesting similarities in the P-T evolution of the three areas.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00002765","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":"AA1072335X","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 Geological Sciences, College of Liberal Arts, Okayama, University"},{"subitem_text_language":"en","subitem_text_value":"Geological Survey of Japan"},{"subitem_text_language":"en","subitem_text_value":"Department of Geological Sciences, University of Maine"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"ABSTRACT"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1994-09-01"}],"displaytype":"detail","filename":"KJ00002368395.pdf","filesize":[{"value":"89.8 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002368395","url":"https://nipr.repo.nii.ac.jp/record/2765/files/KJ00002368395.pdf"},"version_id":"4722c7ee-0634-434b-9114-52088463384b"}]},"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":"RELICT SAPPHIRINE IN PYROPIC GARNET FROM THE EASTERN SØR RONDANE MOUNTAINS, ANTARCTICA","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"RELICT SAPPHIRINE IN PYROPIC GARNET FROM THE EASTERN SØR RONDANE MOUNTAINS, ANTARCTICA"}]},"item_type_id":"1","owner":"4","path":["421"],"pubdate":{"attribute_name":"公開日","attribute_value":"1994-09-01"},"publish_date":"1994-09-01","publish_status":"0","recid":"2765","relation_version_is_last":true,"title":["RELICT SAPPHIRINE IN PYROPIC GARNET FROM THE EASTERN SØR RONDANE MOUNTAINS, ANTARCTICA"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:42:50.767012+00:00"}
