It is composed of well-layered pelitic and basic gneisses with subordinate amounts of calc-silicate rock. The petrographical examinations revealed that the assemblages of sillimanite+Kfeldspar+biotite in the pelitic gneiss, and garnet+clinopyroxene+orthopyroxene+plagioclase+quartz in the basic gneiss are observed to have coexisted stably. Sillimanite+spinel assemblage included in porphyroblastic garnet is totally interpreted to be a breakdown product after staurolite during the prograde recrystallization. The present phase relations and geothermo-barometries yielded the metamorphic conditions of Botnnuten rocks to be 750-800℃ at 5-6 kbars. On the basis of the petrographical features with respect to the occurrence of aluminous silicate minerals and the recrystallization history inferred from the textural relationships, and the P-T conditions mentioned above, it is concluded that Botnnuten is a low-pressure portion of the Lutzow-Holm Complex.","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 Geology and Mineralogy, Faculty of Science, HokkaidoUniversity/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":"1985-09-01"}],"displaytype":"detail","filename":"KJ00000012421.pdf","filesize":[{"value":"2.9 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012421","url":"https://nipr.repo.nii.ac.jp/record/1789/files/KJ00000012421.pdf"},"version_id":"2793b81c-6668-48f0-ae00-0134ccb72c41"}]},"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":"Petrography and geothermometry-geobarometry of Botnnuten, East Antarctica","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Petrography and geothermometry-geobarometry of Botnnuten, East Antarctica","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["391"],"pubdate":{"attribute_name":"公開日","attribute_value":"1985-09-01"},"publish_date":"1985-09-01","publish_status":"0","recid":"1789","relation_version_is_last":true,"title":["Petrography and geothermometry-geobarometry of Botnnuten, East Antarctica"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:53:22.623485+00:00"}
