One sample (biotite-rich fraction) of foliated granitoid gave three age increments of 491Ma, 502Ma and 506Ma, with K/Ca ratios suggesting influence of cooling ages of biotite (younger age) and that of hornblende (older age). Granitoid emplacement is thought to have been before 506Ma, with cooling from biotite closure temperatures about 490Ma. A sample of unfoliated granitoid gave ages of 467-496Ma. The similarity of ages determined for both \"pre-tectonic\" and \"post-tectonic\" samples indicate closure of isotopic systems around 490Ma due to regional uplift/exhumation, rather than actual emplacement ages of individual plutons in South Victoria Land.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00002793","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":"Kanto Gakuen University"},{"subitem_text_language":"en","subitem_text_value":"Deptartment of Applied Geology, Universtiy of Technology:Department of Earth and Planetary Sciences, Graduate School of Science, Hokkaido University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1995-09-01"}],"displaytype":"detail","filename":"KJ00002368423.pdf","filesize":[{"value":"970.3 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002368423","url":"https://nipr.repo.nii.ac.jp/record/2793/files/KJ00002368423.pdf"},"version_id":"11b2c8ef-e220-486b-81c5-50f96723aa94"}]},"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":"^<40>Ar-^<39>Ar GEOCHRONOLOGICAL STUDIES OF GRANITIC ROCKS FROM SOUTH VICTORIA LAND, ANTARCTICA","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"^<40>Ar-^<39>Ar GEOCHRONOLOGICAL STUDIES OF GRANITIC ROCKS FROM SOUTH VICTORIA LAND, ANTARCTICA"}]},"item_type_id":"1","owner":"4","path":["422"],"pubdate":{"attribute_name":"公開日","attribute_value":"1995-09-01"},"publish_date":"1995-09-01","publish_status":"0","recid":"2793","relation_version_is_last":true,"title":["^<40>Ar-^<39>Ar GEOCHRONOLOGICAL STUDIES OF GRANITIC ROCKS FROM SOUTH VICTORIA LAND, ANTARCTICA"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:42:27.410801+00:00"}
