The initial ε Nd values for the felsic gneisses of the Mount Pardoe and Tonagh Island are -3.5 (-3.0&acd;-6.4) and -9.5 (-9.2&acd;-9.8), respectively which are low compared with that of CHUR (Chondritic Uniform Reservoir). This suggests that these rocks had a long crustal history before ca. 2500 Ma. The Sm-Nd ages obtained from the whole-rock samples do not represent the primary age, but correspond to the D_3-M_3 tectonothermal event. The difference in initial ε Nd value for the mafic gneisses of Mount Pardoe and Tonagh Island may reflect the different chemical compositions of the protolith. In the Rb-Sr whole-rock isochron diagram, the felsic gneisses at Mount Pardoe yield an age of 2919±233 Ma with an initial ^<87>Sr/^<86>Sr ratio of 0.70581±0.00027. Mafic gneisses at Mount Pardoe give an Rb-Sr whole-rock isochron age of 2908±216 Ma with an initial ^<87>Sr/^<86>Sr ratio of 0.70517±0.00098.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00002846","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 Natural Environment, Faculty of Human Development, Kobe University"},{"subitem_text_language":"en","subitem_text_value":"Graduate School of Science and Technology, Niigata University"},{"subitem_text_language":"en","subitem_text_value":"Graduate School of Science and Technology, Niigata University"},{"subitem_text_language":"en","subitem_text_value":"Geological Survey of Japan, Hokkaido Branch"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1997-09-01"}],"displaytype":"detail","filename":"KJ00002368119.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002368119","url":"https://nipr.repo.nii.ac.jp/record/2846/files/KJ00002368119.pdf"},"version_id":"bc44d98b-1083-4730-a969-8519529e86c2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Napier Complex","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"geochronology","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mafic gneiss","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Sm-Nd age","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Mount Pardoe","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":"PRELIMINARY RESULT FOR THE Nd AND Sr ISOTOPE CHARACTERISTICS OF THE ARCHAEAN GNEISSES FROM MOUNT PARDOE, NAPIER COMPLEX, EAST ANTARCTICA","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"PRELIMINARY RESULT FOR THE Nd AND Sr ISOTOPE CHARACTERISTICS OF THE ARCHAEAN GNEISSES FROM MOUNT PARDOE, NAPIER COMPLEX, EAST ANTARCTICA"}]},"item_type_id":"1","owner":"4","path":["424"],"pubdate":{"attribute_name":"公開日","attribute_value":"1997-09-01"},"publish_date":"1997-09-01","publish_status":"0","recid":"2846","relation_version_is_last":true,"title":["PRELIMINARY RESULT FOR THE Nd AND Sr ISOTOPE CHARACTERISTICS OF THE ARCHAEAN GNEISSES FROM MOUNT PARDOE, NAPIER COMPLEX, EAST ANTARCTICA"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:41:39.108760+00:00"}
