These volcanism might have taken place in close association with multiple formations of NS-trending grabens. The rifting of the Japan Sea might have caused the formation of the first stage graben of late Oligocene to early Miocene. During the spreading of the Japan Sea, the second stage graben has been formed in submarine environments. Within this submarine deep graben, middle Miocene basaltic and rhyolitic rocks were extensively accumulated and they have been buried in the level deeper than 5, 000～6, 000m since middle Miocene. The deep seated early to middle Miocene basalts can be divided into three different groups based on initia1 Sr isotopic ratios (Sri) and ε Nd values. Sri and ε Nd values expected for unaltered samples of each group are as follows； Sri＝0.7032-0.7033 and ε Nd =+6～+8 for group I, Sri＝0.7038-0.7040 and ε Nd=+4～+5 for group II, Sri=0.7045-0.7050 and ε Nd=0～+2 for group III. middle Miocene rhyolites from the Tsugawa and Tadami areas show significantly higher Sri ratios (0.7055-0.7080) and lower ε Nd values (-8～0) than the basaltic rocks. Basaltic magmas of group III are considered to have formed from the sub-island arc lithospheric mantle with an undepleted isotope signature, while those of groups I and II are from the hot mantle with a depleted isotope signature, upwelling from the athenosphere to the sub-island arc lithospheric mantle during the spreading of the Japan Sea. Genesis of rhyolitic rocks from the underground and surface outcrops in the Tsugawa and Tadami areas may be ascribed to the partial melting of the lower crust.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"40889","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Shuto, Kenji"}]},{"nameIdentifiers":[{"nameIdentifier":"40890","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kato, Susumu"}]},{"nameIdentifiers":[{"nameIdentifier":"40891","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ohki, Jun'ichi"}]},{"nameIdentifiers":[{"nameIdentifier":"40892","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kagami, Hiroo"}]},{"nameIdentifiers":[{"nameIdentifier":"40893","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Arato, Hiroyuki"}]},{"nameIdentifiers":[{"nameIdentifier":"40894","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Rezanove, Andrey I."}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"石油技術協会"}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"石油技術協会"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00130976","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03709868","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"周藤, 賢治"}],"nameIdentifiers":[{"nameIdentifier":"40883","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"加藤, 進"}],"nameIdentifiers":[{"nameIdentifier":"40884","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大木, 淳一"}],"nameIdentifiers":[{"nameIdentifier":"40885","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"加々美, 寛雄"}],"nameIdentifiers":[{"nameIdentifier":"40886","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"荒戸, 裕之"}],"nameIdentifiers":[{"nameIdentifier":"40887","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"アンドレイ, レザノフ"}],"nameIdentifiers":[{"nameIdentifier":"40888","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":"2019-07-30"}],"displaytype":"detail","filename":"ZA_62(1)_45-58.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ZA_62(1)_45-58.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/3114/files/ZA_62(1)_45-58.pdf"},"version_id":"5610c5ac-2663-43c8-afc6-fe03f0874dbc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Niigata oil and gas fields","subitem_subject_scheme":"Other"},{"subitem_subject":"bimodal volcanism","subitem_subject_scheme":"Other"},{"subitem_subject":"early to middle miocene","subitem_subject_scheme":"Other"},{"subitem_subject":"graben","subitem_subject_scheme":"Other"},{"subitem_subject":"Sr and Nd isotope","subitem_subject_scheme":"Other"},{"subitem_subject":"Sub-island arc mantle","subitem_subject_scheme":"Other"},{"subitem_subject":"asthenosphere","subitem_subject_scheme":"Other"},{"subitem_subject":"upwelling","subitem_subject_scheme":"Other"},{"subitem_subject":"lower crust","subitem_subject_scheme":"Other"},{"subitem_subject":"the spreading of the Japan Sea","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":"新潟油・ガス田地域における中新世バイモーダル火山活動 : 背弧海盆拡大との関連","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"新潟油・ガス田地域における中新世バイモーダル火山活動 : 背弧海盆拡大との関連"},{"subitem_title":"新潟油・ガス田地域における中新世バイモーダル火山活動 : 背弧海盆拡大との関連","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","489"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-04-11"},"publish_date":"2012-04-11","publish_status":"0","recid":"3114","relation_version_is_last":true,"title":["新潟油・ガス田地域における中新世バイモーダル火山活動 : 背弧海盆拡大との関連"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:17.710632+00:00"}
