The change of trace element concentrations, ^<87>Rb/^<86>Sr and ^<147>Sm/^<144>Nd ratios in andesite by chemical weathering supports dissolution of plagioclase by this process as indicated in Sagara et al. (1997). The ^<87>Sr/^<86>Sr and ^<143>Nd/^<144>Nd ratios, however, are almost constant, because Sr and Nd isotopic ratios among minerals have small variation. This is caused by its young formation age. The ^<87>Sr/^<86>Sr and ^<143>Nd/^<144>Nd ratios of surface waters in the Kanayama-sawa river are close to those ratios of andesites. However, ^<87>Rb/^<86>Sr and ^<147>Sm/^<144>Nd ratios are lower than the ratios of andesites. These observations indicate that Sr and Nd in surface waters originated from plagioclases of these andesites.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"161014","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yuhara, Masaki"}]},{"nameIdentifiers":[{"nameIdentifier":"161015","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sagara, Wataru"}]},{"nameIdentifiers":[{"nameIdentifier":"161016","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Takahashi, Toshiro"}]},{"nameIdentifiers":[{"nameIdentifier":"161017","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Watanabe, Naoki"}]},{"nameIdentifiers":[{"nameIdentifier":"161018","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yamagishi, Hiromitsu"}]},{"nameIdentifiers":[{"nameIdentifier":"161019","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Marui, Hideaki"}]}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟大学積雪地域災害研究センター"}]},"item_7_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00183327","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03877892","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"柚原, 雅樹"}],"nameIdentifiers":[{"nameIdentifier":"161008","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"相楽, 渉"}],"nameIdentifiers":[{"nameIdentifier":"161009","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高橋, 俊郎"}],"nameIdentifiers":[{"nameIdentifier":"161010","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"渡部, 直喜"}],"nameIdentifiers":[{"nameIdentifier":"161011","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山岸, 宏光"}],"nameIdentifiers":[{"nameIdentifier":"161012","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"丸井, 英明"}],"nameIdentifiers":[{"nameIdentifier":"161013","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":"2019-08-20"}],"displaytype":"detail","filename":"21_73-82.pdf","filesize":[{"value":"402.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"21_73-82.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/28016/files/21_73-82.pdf"},"version_id":"7a79d91a-37cf-4667-98b9-ea66466dfaf5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Hieda-yama landslide area","subitem_subject_scheme":"Other"},{"subitem_subject":"Sr and Nd isotopic compositions","subitem_subject_scheme":"Other"},{"subitem_subject":"Chemical weathering","subitem_subject_scheme":"Other"},{"subitem_subject":"Surface water","subitem_subject_scheme":"Other"},{"subitem_subject":"稗田山崩壊地","subitem_subject_scheme":"Other"},{"subitem_subject":"Sr・Nd同位体比組成","subitem_subject_scheme":"Other"},{"subitem_subject":"化学風化作用","subitem_subject_scheme":"Other"},{"subitem_subject":"地表水","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"長野県稗田山崩壊地周辺に分布する岩石および地表水のSr・Nd同位体比組成","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"長野県稗田山崩壊地周辺に分布する岩石および地表水のSr・Nd同位体比組成"},{"subitem_title":"長野県稗田山崩壊地周辺に分布する岩石および地表水のSr・Nd同位体比組成","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1562"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-03-08"},"publish_date":"2016-03-08","publish_status":"0","recid":"28016","relation_version_is_last":true,"title":["長野県稗田山崩壊地周辺に分布する岩石および地表水のSr・Nd同位体比組成"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T04:27:04.692684+00:00"}
