It synthesises results from different disciplines into a coherent unifying model. A simple mechanism is formulated which causally relates changes in geophysical phenomena-reversals in the Earth's magnetic field, superchrons where this cycle is suspended for long periods, polar ice variations and superplume volcanism, which gives rise to flood basalts-with astrophysical drivers from impacts and solar system penetration of interstellar gas clouds. This interrelated sequence in turn gives rise to the dramatic extinction events at the Cretaceous/Tertiary and Permian/Triassic boundaries and produces signatures associated with both cataclysmic and gradual extinctions. The question of geological versus astrophysical mechanisms for extinction are argued to be resolved into a coupled mechanism which is consistent with geological and palaeontological data so far known.","subitem_description_type":"Other"}]},"item_6_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"8","subitem_description_type":"Other"}]},"item_6_description_16":{"attribute_name":"アクセション番号","attribute_value_mlt":[{"subitem_description":"KJ00003971691","subitem_description_type":"Other"}]},"item_6_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_6_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Artcle","subitem_description_type":"Other"}]},"item_6_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN10065972","subitem_source_identifier_type":"NCID"}]},"item_6_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09145575","subitem_source_identifier_type":"ISSN"}]},"item_6_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"奈良産業大学情報学部"},{"subitem_text_value":"ロンドン大学"}]},"item_6_text_7":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Bulletin of Nara Sangrvo University"},{"subitem_text_language":"en","subitem_text_value":"0ueen Marv and Westfield College, Univ."}]},"item_6_title_3":{"attribute_name":"論文名よみ","attribute_value_mlt":[{"subitem_title":"The Spiral Arms, Superplumes and a Unified Model of Mass Extinctions"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"藪下, 信"},{"creatorName":"ヤブシタ, シン","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"2579","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"アレン"}],"nameIdentifiers":[{"nameIdentifier":"2580","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"YABUSHITA, Shin","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"2581","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Alien, A.J.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"2582","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-12-09"}],"displaytype":"detail","filename":"KJ00003971691.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00003971691.pdf","url":"https://naragakuen.repo.nii.ac.jp/record/2145/files/KJ00003971691.pdf"},"version_id":"1dc0ee74-6ed6-439e-841d-0a4ff414997a"}]},"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":"The Spiral Arms, Superplumes and a Unified Model of Mass Extinctions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The Spiral Arms, Superplumes and a Unified Model of Mass Extinctions","subitem_title_language":"en"}]},"item_type_id":"6","owner":"3","path":["428"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-12-09"},"publish_date":"2016-12-09","publish_status":"0","recid":"2145","relation_version_is_last":true,"title":["The Spiral Arms, Superplumes and a Unified Model of Mass Extinctions"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T14:40:55.362715+00:00"}
