The highest metamorphic P-T condition reaches granulite facies. Syn-metamorphic S- and I-type tonalites are intruded into the crustal layer. Large amount of Pyroxene-bearing S-type tonalites are distributed in the Mt. Esaoman-tottabetsu-dake region, northen part of the HMB. The S-type suite is intruded into the granulite facies metamorphic layers and is believed to have crystallized under lower crustal P-T conditions. In the S-type tonalite suite, pyroxene bearing I-type tonalite bodies are found. The I－type tonalites occur as small bodies within the S-type tonalites. Both boundaries are vauge, but some I-type tonalite bodies show chilled margin. The mineral assemblage of the I－type tonalite is Bt+Hbl+Opx±Cpx±Cum+Pl+Qtz. Petrochemical features indicate that the the I-type tonalite generated from mafic metamorphic rocks (N-MORB composition metabasites). Mass balance calculation and batch partial melting modeling indicate that the melting degree is about 29% and 10-30%, respectively. The I-type tonalite is thought to be generated by crustal anatexis of the mafic metamorphic rocks in the lowermost crust.","subitem_description_type":"Abstract"},{"subitem_description":"日高変成帯北部のエサオマントッタベツ岳地域において，斜方輝石や単斜輝石を含有するIタイプトーナル岩を見いだした．この岩石は下部地殻性のSタイプトーナル岩体内部の小岩体として産する．この岩石について岩石学的研究を行った．その結果，このIタイプマグマはN-MORB組成の塩基性変成岩類が部分溶融して形成されたことが明らかになった．また，その塩基性変成岩類の溶融度は，主成分元素のマスバランスから29%程度，微量元素のモデル計算から10～30%程度であったと推定される．このIタイプトーナル岩は，日高変成帯の最下部地殻のアナテクシスにより発生したマグマであると考えられる．","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"41523","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Shimura, Toshiaki"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本地質学会"}]},"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":"AN00141768","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00167630","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"志村, 俊昭"}],"nameIdentifiers":[{"nameIdentifier":"41522","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":"ZC_105(8)_536-551.pdf","filesize":[{"value":"2.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ZC_105(8)_536-551.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/3224/files/ZC_105(8)_536-551.pdf"},"version_id":"eed1baee-3361-4ae3-b105-4943ba921a97"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"lower crust","subitem_subject_scheme":"Other"},{"subitem_subject":"granulite","subitem_subject_scheme":"Other"},{"subitem_subject":"I-type granite","subitem_subject_scheme":"Other"},{"subitem_subject":"anatexis","subitem_subject_scheme":"Other"},{"subitem_subject":"MORB","subitem_subject_scheme":"Other"},{"subitem_subject":"Hidaka Metamorphic Belt","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":"日高変成帯、含輝石Ｉタイプトーナル岩の成因と原岩の溶融度","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"日高変成帯、含輝石Ｉタイプトーナル岩の成因と原岩の溶融度"},{"subitem_title":"日高変成帯、含輝石Ｉタイプトーナル岩の成因と原岩の溶融度","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":"3224","relation_version_is_last":true,"title":["日高変成帯、含輝石Ｉタイプトーナル岩の成因と原岩の溶融度"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:22.945754+00:00"}
