The formation is of Late Campanian to Maastrichtian age based on the radiolarian fossil zone. CH-1 is a coarse pumiceous crystal tuff, and CH-2 is a coarse vitric crystal tuff. These specimens include three types of zircons; A group is characterized by euhedral form without abrasion, B group is euhedral but less abraded, and C group is much abraded and purplish. These characteristics of zircons indicate that A group is essential, while the others are detrital. A and B groups are major constituents and were selected for fission-track dating. The results demonstrate no significant difference in frequency distribution of grain age between both groups. Fission-track dating for essential zircons gave ages of 69.8±3.7 Ma (CH-1), and 67.5±3.4 Ma (CH-2). The FT ages of the tuff are within the age range of the radiolarian fossil zone of the Ryujin Formation, and indicate that the lower Ryujin Formation is of Late Maastrichtian age. The age constraint, in addition to previous geologic data, suggests that the coarse acidic tuff was derived from the simultaneous rhyolite pyroclastic rocks such as the Nohi Rhyolite and Suyama Pyroclastic Rocks distributed in the Chubu District of Southwest Japan.","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"地質学雑誌. 102(2):116-124 (1996)","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"公文, 富士夫","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.ZUchOUkh.html"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本地質学会"}]},"item_6_relation_51":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110003022645/","subitem_relation_type_select":"URI"}}]},"item_6_rights_62":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本地質学会"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0016-7630","subitem_source_identifier_type":"ISSN"}]},"item_6_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00141768","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"木村,  克己"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"別所,  孝範"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"坂本,  隆彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"公文,  富士夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"鈴木,  博之"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"chishitsu_102_2-1.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"chishitsu_102_2-1.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/11862/files/chishitsu_102_2-1.pdf"},"version_id":"836117c5-8e06-4f78-82cc-f097e0918bd1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"fission-track","subitem_subject_scheme":"Other"},{"subitem_subject":"dating","subitem_subject_scheme":"Other"},{"subitem_subject":"zircon","subitem_subject_scheme":"Other"},{"subitem_subject":"Maastrichtian","subitem_subject_scheme":"Other"},{"subitem_subject":"Shimanto Belt","subitem_subject_scheme":"Other"},{"subitem_subject":"Ryujin Formation","subitem_subject_scheme":"Other"},{"subitem_subject":"acidic tuff","subitem_subject_scheme":"Other"},{"subitem_subject":"Nohi Ryolite","subitem_subject_scheme":"Other"}]},"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":"紀伊半島四万十累層群の上部白亜系竜神累層に挟まれる酸性凝灰岩のフィッション・トラック年代とその意義","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"紀伊半島四万十累層群の上部白亜系竜神累層に挟まれる酸性凝灰岩のフィッション・トラック年代とその意義","subitem_title_language":"ja"}]},"item_type_id":"6","owner":"1","path":["1170"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2011-03-28"},"publish_date":"2011-03-28","publish_status":"0","recid":"11862","relation_version_is_last":true,"title":["紀伊半島四万十累層群の上部白亜系竜神累層に挟まれる酸性凝灰岩のフィッション・トラック年代とその意義"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-14T04:00:45.416143+00:00"}
