Samples were targeted for dating that showed a marked difference in cooling age across the Takasegawa Fault (Ito and Tanaka, 1999). The Okukurobe granite to the west of the fault, and the Oshirasawa granite to the east of the fault, yielded ages of 65.1 ± 1.6 Ma and 64.7 ± 2.3 Ma, respectively. These ages imply that both granites were intruded at the same time (ca. 65 Ma). The Oshirasawa granite has a mylonitic texture, which probably reflects rapid uplift and erosion by faulting in the past 2 Myr. The Kanazawa granodiorite to the east of the Takasegawa Fault was dated as 2.15 ± 0.15 Ma, indicating that this pluton was intruded in the Quaternary. In addition to the Takidani granodiorite, this is the second confirmed occurrence of an outcropping Quaternary pluton in the Hida Mountain Range.","subitem_description_type":"Abstract"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本地質学会 = Geological Society of Japan"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.5575/geosoc.2012.0014","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.geosociety.jp/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.jstage.jst.go.jp/browse/geosoc","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © 日本地質学会 Geological Society of Japan"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00141768","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0016-7630","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"伊藤, 久敏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田村, 明弘"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"森下, 知晃"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"荒井, 章司"}],"nameIdentifiers":[{},{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"SC-PR-ARAI-S-449.pdf","filesize":[{"value":"3.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SC-PR-ARAI-S-449.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/10468/files/SC-PR-ARAI-S-449.pdf"},"version_id":"53a5f0cd-4613-4525-be5d-96ff9c8e431d"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"飛騨山脈の深成岩マグマの貫入時期とテクトニクス: LA-ICP-MSによるジルコンのU-Pb年代測定法の適用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"飛騨山脈の深成岩マグマの貫入時期とテクトニクス: LA-ICP-MSによるジルコンのU-Pb年代測定法の適用"},{"subitem_title":"Timing of some plutonic intrusions and tectonics in the Hida Mountain Range: An application of LA-ICP-MS U-Pb dating on zircons","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["937"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"10468","relation_version_is_last":true,"title":["飛騨山脈の深成岩マグマの貫入時期とテクトニクス: LA-ICP-MSによるジルコンのU-Pb年代測定法の適用"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T01:40:25.395348+00:00"}
