A pumice-fall deposit underlying the lava was identified, and it was correlated to Aso central cone pumice 4 (ACP4), one of the key tephra layers in and around Aso caldera. A non-carbonized root sample was discovered just below ACP4, and its ^14C age was measured to determine the age of the eruption cycle producing ACP4 and the Tateno lava. The AMS ^14C age was >43,200yrs BP, which corresponded to >ca. 46cal ka. The age is consistent with a K-Ar age (51±5ka) for the Takanoobane lava, which occurs above the Tateno lava. In the western part of Aso central cones, two thick felsic lava flows, the Tateno lava (decite) and the Takanoobane lava (rhyolite), were discharged at an interval of a few hundreds years around 50ka, and they accompanied precursour plinian pumice-fall deposits.","subitem_description_type":"Other"}]},"item_16_description_77":{"attribute_name":"URL","attribute_value_mlt":[{"subitem_description":"https://www.jstage.jst.go.jp/article/jaqua1957/43/5/43_5_353/_article/-char/ja/","subitem_description_type":"Other"}]},"item_16_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本第四紀学会"}]},"item_16_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 日本第四紀学会"}]},"item_16_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"04182642","subitem_source_identifier_type":"ISSN"}]},"item_16_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN0034136X","subitem_source_identifier_type":"NCID"}]},"item_16_subject_20":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453.8","subitem_subject_scheme":"NDC"}]},"item_16_text_18":{"attribute_name":"形態","attribute_value_mlt":[{"subitem_text_value":"1752580 bytes"}]},"item_16_text_47":{"attribute_name":"資源タイプ・ローカル","attribute_value_mlt":[{"subitem_text_value":"雑誌掲載論文"}]},"item_16_text_48":{"attribute_name":"資源タイプ・NII","attribute_value_mlt":[{"subitem_text_value":"Journal Article"}]},"item_16_text_49":{"attribute_name":"資源タイプ・DCMI","attribute_value_mlt":[{"subitem_text_value":"text"}]},"item_16_text_50":{"attribute_name":"資源タイプ・ローカル表示コード","attribute_value_mlt":[{"subitem_text_value":"01"}]},"item_16_version_type_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"http://www.isni.org/isni/"}],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"宮縁, 育夫","creatorNameLang":"ja"},{"creatorName":"Miyabuchi, Yasuo","creatorNameLang":"en"},{"creatorName":"ミヤブチ, ヤスオ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"宮縁","familyNameLang":"ja"},{"familyName":"Miyabuchi","familyNameLang":"en"},{"familyName":"ミヤブチ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"育夫","givenNameLang":"ja"},{"givenName":"Yasuo","givenNameLang":"en"},{"givenName":"ヤスオ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"147108","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"増田, 直朗"}],"nameIdentifiers":[{"nameIdentifier":"137889","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"渡辺, 一徳"}],"nameIdentifiers":[{"nameIdentifier":"137890","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":"2020-03-03"}],"displaytype":"detail","filename":"第四紀研究43(5)p353-358.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"第四紀研究43(5)p353-358.pdf","url":"https://kumadai.repo.nii.ac.jp/record/29928/files/第四紀研究43(5)p353-358.pdf"},"version_id":"de15c8a1-0811-4124-bc42-0f67a807d2bb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"阿蘇火山","subitem_subject_scheme":"Other"},{"subitem_subject":"中央火口丘群","subitem_subject_scheme":"Other"},{"subitem_subject":"立野溶岩","subitem_subject_scheme":"Other"},{"subitem_subject":"降下軽石","subitem_subject_scheme":"Other"},{"subitem_subject":"加速器^14C年代","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":"阿蘇火山において立野溶岩を流出した噴火サイクルの特徴と年代","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"阿蘇火山において立野溶岩を流出した噴火サイクルの特徴と年代"}]},"item_type_id":"16","owner":"1","path":["444"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-05-31"},"publish_date":"2017-05-31","publish_status":"0","recid":"29928","relation_version_is_last":true,"title":["阿蘇火山において立野溶岩を流出した噴火サイクルの特徴と年代"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-09-26T04:24:11.405188+00:00"}
