Extensive partial melting has been observed in pelitic to psammitic gneisses. The age of metamorphism has been dated to be Late Proterozoic based on a Rb-Sr whole rock isochron (SHERATON and COLLERSON; BMR J. Aust. Geol. Geophys., 8,119,1983). The rocks have been subjected to low-pressure granulite-facies metamorphism as evidenced by the following petrographical observations. 1) Pelitic to psammitic gneisses : Cordierite occurs regionally in pelitic gneisses. Andalusite and sillimanite coexist in a cordierite gneiss, in which andalusite occurs as a retrograde mineral being associated with chlorite. 2) Basic to intermediate gneisses : Orthopyroxene occurs regionally in basic to intermediate gneisses, being occasionally associated with clinopyroxene, amphibole and biotite. Garnet is rare, but where it occurs, coronas composed of plagioclase+clinopyroxene+magnetite symplectite are observed around garnet. 3) Ultramafic rocks : Olivene+plagioclase intergrowth is observed in ultramafic rocks. Mineral equilibria and geothermo-barometries yield initial P-T conditions around 750℃ at 5±1 kbar. Prior to the low-pressure granulite-facies metamorphism (possibly in Late Proterozoic), the rocks had been recrystallized at much higher P-T conditions around 950-1050℃ at&sime;10kbar deduced from local occurrence of pyrope-rich garnet (up to X_<Mg> 70-72) in basic granulites.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00002644","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":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"Department of Applied Geology, University of New South Wales"},{"subitem_text_language":"en","subitem_text_value":"Department of Applied Geology, University of New South Wales"}]},"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":"1990-09-01"}],"displaytype":"detail","filename":"KJ00002368256.pdf","filesize":[{"value":"99.9 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002368256","url":"https://nipr.repo.nii.ac.jp/record/2644/files/KJ00002368256.pdf"},"version_id":"93d3c74d-1097-40d6-9109-2690f69f891b"}]},"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":"LOW-PRESSURE GRANULITE-FACIES METAMORPHISM IN THE PRYDZ BAY REGION, EAST ANTARCTICA","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"LOW-PRESSURE GRANULITE-FACIES METAMORPHISM IN THE PRYDZ BAY REGION, EAST ANTARCTICA"}]},"item_type_id":"1","owner":"4","path":["418"],"pubdate":{"attribute_name":"公開日","attribute_value":"1990-09-01"},"publish_date":"1990-09-01","publish_status":"0","recid":"2644","relation_version_is_last":true,"title":["LOW-PRESSURE GRANULITE-FACIES METAMORPHISM IN THE PRYDZ BAY REGION, EAST ANTARCTICA"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:44:19.481993+00:00"}
