These plutonic rocks can be categorized based on their\npetrological characteristics and active periods into four groups: early\nCretaceous (EC), late Cretaceous (LC), Poleogene (PG), and Neogene\n(NG). The initial Sr isotopic ratio of the PG and NG groups increased,\nwhereas the initial Nd isotopic ratio decreased with increasing aluminum\nsaturation index (ASI), thereby indicating the influence of the upper crustal\nmaterial. The LC group also exhibits a high initial Sr isotopic ratio, a low\ninitial Nd isotopic ratio, and high ASI, presuming that the source magma\nreacted with the upper portion of the crustal material. Such reactions with\nthe upper crustal material were observed to have occurred three times between\nCretaceous and Neogene, and these events may have been caused by\nchanges in the tectonics of the Ryukyu Arc.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Rissho　University","subitem_publisher_language":"en"}]},"item_2_version_type_18":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kawano, Yoshinobu","creatorNameLang":"en"},{"creatorName":"川野, 良信","creatorNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-11-07"}],"displaytype":"detail","filename":"07_Kawano_p137-169.pdf","filesize":[{"value":"2.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"07_Kawano_p137-169.pdf","objectType":"fulltext","url":"https://rissho.repo.nii.ac.jp/record/27/files/07_Kawano_p137-169.pdf"},"version_id":"935fcc41-a600-4523-9d9b-9fd896b0483e"}]},"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":"book part","resourceuri":"http://purl.org/coar/resource_type/c_3248"}]},"item_title":"Petrogenesis of Plutonic Rocks in the Ryukyu Arc, Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Petrogenesis of Plutonic Rocks in the Ryukyu Arc, Japan","subitem_title_language":"en"}]},"item_type_id":"2","owner":"8","path":["10"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2019-05-15"},"publish_date":"2019-05-15","publish_status":"0","recid":"27","relation_version_is_last":true,"title":["Petrogenesis of Plutonic Rocks in the Ryukyu Arc, Japan"],"weko_creator_id":"8","weko_shared_id":-1},"updated":"2023-09-06T02:01:53.166785+00:00"}
