The behavior of halogen elements in the mineralization was considered based on the chemical compositions of biotite and apatite.\nThe Si and Mg/(Mg+Fe) of biotite increased, and Ti decreased with advancing hydrothermal activity. The change of chemical composition of biotite suggested a decrease of temperature and/or an increase of oxygen fugacity.\nBiotite and apatite were characterized by an enrichment of F, as well as an enrichment of\nother incompatible elements (apatite), compared to those in the island arc regions in Papua New Guinea. The magmatism in this field might originate in the continental crust, or might be strongly contaminated with crustal materials. The fHF/fH_2O ratios on isothermal projection suggested further concentration of F in the residual magma during solidification of originally\nF-rich magma.\nThe fHCl/fH_2O ratio in magma in the Ok Tedi mining district was similar to those in island arc region. The ratio has a tendency not to concentrate in the ordinary acidic magmatism of the continental region, that is, the Ok Tedi mining district should be regarded as an abnormal Cl enriched field. The fHCl/fH_2O ratio on isothermal projection has increased at the veining stages.\nThe effective transportation mechanism of base metals in the Ok Tedi mining district was suggested by HOLLAND's simulation (1972).","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":"Malagun, Salam","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamamoto, Masahiko","creatorNameLang":"en"},{"creatorName":"ヤマモト, マサヒコ","creatorNameLang":"ja-Kana"},{"creatorName":"山本, 温彦","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":[{}]},{"creatorNames":[{"creatorName":"Shiga, Yoshihide","creatorNameLang":"en"},{"creatorName":"志賀, 美英","creatorNameLang":"ja"},{"creatorName":"シガ, ヨシヒデ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Higashi, Shoji","creatorNameLang":"en"},{"creatorName":"ヒガシ, ショウジ","creatorNameLang":"ja-Kana"},{"creatorName":"東, 正治","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":"2016-10-27"}],"displaytype":"detail","filename":"AN10088628_v11-2_P69-81.pdf","filesize":[{"value":"3.2 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"AN10088628_v11-2_P69-81.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/2506/files/AN10088628_v11-2_P69-81.pdf"},"version_id":"0c7a345d-52b6-4096-8c7b-7ec44e66e26e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Ok Tedi","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Halogen elements","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Epicontinental","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":"Halogen Geochemistry in the Ok Tedi Porphyry Copper System, Papua New Guinea","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Halogen Geochemistry in the Ok Tedi Porphyry Copper System, Papua New Guinea","subitem_title_language":"en"}]},"item_type_id":"6","owner":"18","path":["5581","34"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-01-22"},"publish_date":"2013-01-22","publish_status":"0","recid":"2506","relation_version_is_last":true,"title":["Halogen Geochemistry in the Ok Tedi Porphyry Copper System, Papua New Guinea"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-26T00:35:40.821951+00:00"}
