Some low-Ti biotites and hornblendes may be due to low TiO_2 content of host rocks. Chemical natures of biotites and hornblendes reflect those of their host rocks, that is, biotites from metabasites are phlogopite and Na_2O-rich ones, while those from paragneisses are Fe-rich and Na_2O-poor ones. The replacement of R^<2+> by R^<3+> ions in octahedral sites in biotites increases from metabasites through charnockites to paragneisses. Hornblendes from metabasites are richer in Na_2O than K_2O, but the proportion is reversed in hornblendes from charnockites and hornblende gneisses. The values of log (&fnof;_<H_2O>/&fnof;_<HF>) of fluid phase coexisting with biotites during crystallization are 4.3 in metabasites and 3.8 in paragneisses, respectively. From the available data of the F content of hydrous minerals in various metamorphic terrains, it can be presumed that the ratio of &fnof;_<H_2O>/&fnof;_<HF> decreases during progressive metamorphism.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Earth Sciences, College of General Education, Tohoku University/Department of Earth Sciences, Faculty of Science, Hirosaki University/National Institute of Polar Research"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1979-10-01"}],"displaytype":"detail","filename":"KJ00000011573.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000011573","url":"https://nipr.repo.nii.ac.jp/record/1029/files/KJ00000011573.pdf"},"version_id":"1925056b-626c-4dc3-a096-acdaa517c676"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Chemical Characteristics of Biotites and Hornblendes from Metamorphic Rocks around Lutzow-Holmbukta, East Antarctica","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Chemical Characteristics of Biotites and Hornblendes from Metamorphic Rocks around Lutzow-Holmbukta, East Antarctica","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["368"],"pubdate":{"attribute_name":"公開日","attribute_value":"1979-10-01"},"publish_date":"1979-10-01","publish_status":"0","recid":"1029","relation_version_is_last":true,"title":["Chemical Characteristics of Biotites and Hornblendes from Metamorphic Rocks around Lutzow-Holmbukta, East Antarctica"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:18:52.473185+00:00"}
