The river water is much lighter. They are well on the meteoric\nwater line (CRAIG, 1961). δ D of the hot spring water in Kairiru Island is -20.0‰, and the Cl- content is 9630 mg/l. The data suggest that the hot spring water originated from the 1:1 mixture of the meteoric water and sea water in this region. Mg^<2+> and SO_4^<2-> were found strongly depleted from the original mixed water. Na^<+> and K^<+> were moderately removed to low concentration. Ca^<2+> was leached\nfrom rocks and resulted in the high concentration in the water. Removal of Mg^<2+> and other cations from the hot spring water was supplimented largely by leaching of Ca^<2+> from rocks. However, the\nδ <18>^O shift by water-rock interaction is not observed. The water temperature at the depth might be about 140°C, and the similarity of δ <34>^S between the hot spring water and sea water suggests that the\nwater-convection was performed under oxidation condition.\nIt is suggested that both sea water and meteoric water were mixed together with the ratio of about 1:1, that the mixed water reacted mainly with the surrounding beach rock at shallow depth, and that the rate of water-rock interaction was not so high to shift the δ <18>^O, or the water/rock ratio was rather high not to affect the δ <18>O value.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_6_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_6_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09160752","subitem_source_identifier_type":"PISSN"}]},"item_6_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN10088628","subitem_source_identifier_type":"NCID"}]},"item_6_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"450","subitem_subject_scheme":"NDC"}]},"item_6_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nedachi, Munetomo","creatorNameLang":"en"},{"creatorName":"ネダチ, ムネトモ","creatorNameLang":"ja-Kana"},{"creatorName":"根建, 心具","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Inoue, Akio","creatorNameLang":"en"},{"creatorName":"イノウエ, アキオ","creatorNameLang":"ja-Kana"},{"creatorName":"井上, 晃男","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Taguchi, Sachihiro","creatorNameLang":"en"},{"creatorName":"タグチ, サチヒロ","creatorNameLang":"ja-Kana"},{"creatorName":"田口, 幸洋","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-31"}],"displaytype":"detail","filename":"AN10088628_v15-1_P1-7.pdf","filesize":[{"value":"658.1 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"AN10088628_v15-1_P1-7.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/11132/files/AN10088628_v15-1_P1-7.pdf"},"version_id":"c789d4dc-b676-4546-8158-84f540d6386d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Geochemistry","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Hot spring water","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Wewak","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Papua New Guinea","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Water geochemistry of the Wewak region, East Sepik Province, Papua New Guinea","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Water geochemistry of the Wewak region, East Sepik Province, Papua New Guinea","subitem_title_language":"en"}]},"item_type_id":"6","owner":"18","path":["5588","34"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-01-22"},"publish_date":"2013-01-22","publish_status":"0","recid":"11132","relation_version_is_last":true,"title":["Water geochemistry of the Wewak region, East Sepik Province, Papua New Guinea"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-26T00:35:27.691824+00:00"}
