Four migmatitic gneisses in the Tenmondai Rock area give an isochron of 780±70Ma with an initial ^<87>Sr/^<86>Sr ratio of 0.70463±33,which is approximately concordant with those of several other areas in eastern Queen Maud Land reported in SHIBATA et al. (Mem. Natl Inst. Polar Res., Spec. Issue. 43,133,1986). The quality of the isochron for Tenmondai Rock is not good because the data points have a small spread in ^<87>Rb/^<86>Sr ratio. As for Rundvagshetta, three of five analyzed granulites give an isochron of 3020±470Ma with an initial ^<87>Sr/^<86>Sr ratio of 0.70515±44. The age is the oldest so far obtained from eastern Queen Maud Land, and corresponds to those of the Archean Napier Complex of Enderby Land. This isochron is essentially controlled by a data point with an extraordinary high ^<87>Sr/^<86>Sr ratio (0.8416). This is quartzofeldspathic gneiss characterized by mesoperthitic texture, which is uncommon in eastern Queen Maud Land. There may be some fragments of Archean basement rocks in the vicinity of Syowa Station.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00002574","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":"Geological Survey of Japan"},{"subitem_text_language":"en","subitem_text_value":"Geological Survey of Japan"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"Department of Earth Sciences, Faculty of Science, Chiba University"}]},"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":"1988-09-01"}],"displaytype":"detail","filename":"KJ00002368164.pdf","filesize":[{"value":"79.0 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002368164","url":"https://nipr.repo.nii.ac.jp/record/2574/files/KJ00002368164.pdf"},"version_id":"7ae254a4-f162-4768-9c09-b110b356d646"}]},"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":"Rb-Sr WHOLE-ROCK AGES OF METAMORPHIC ROCKS FROM EASTERN QUEEN MAUD LAND, EAST ANTARCTICA (2) : TENMONDAI ROCK AND RUNDVAGSHETTA","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Rb-Sr WHOLE-ROCK AGES OF METAMORPHIC ROCKS FROM EASTERN QUEEN MAUD LAND, EAST ANTARCTICA (2) : TENMONDAI ROCK AND RUNDVAGSHETTA"}]},"item_type_id":"1","owner":"4","path":["416"],"pubdate":{"attribute_name":"公開日","attribute_value":"1988-09-01"},"publish_date":"1988-09-01","publish_status":"0","recid":"2574","relation_version_is_last":true,"title":["Rb-Sr WHOLE-ROCK AGES OF METAMORPHIC ROCKS FROM EASTERN QUEEN MAUD LAND, EAST ANTARCTICA (2) : TENMONDAI ROCK AND RUNDVAGSHETTA"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:45:18.964696+00:00"}
