Orthopyroxene+sillimanite±quartz assemblages reveal high-T, high-P conditions for peak metamorphism of granulites of Rundvagshetta. Moreover, their fabrics imply regional ductile deformation during peak metamorphism, which was characterized by the formation of a WNW-ESE subhorizontal mineral lineation and the development of high-strain structures such as isoclinal buckling folds (F_n) and boudinage (B_n and B_m). The high-strain deformation was followed by the development of symplectic intergrowths of cordierite±sapphirine±spinel around sillimanite and orthopyroxene, and symplectic intergrowths of orthopyroxene+cordierite±sapphirine around garnets in response to decompression. There is little symplectic intergrowth strained intensely, whereas strained cordierite is locally observed. It implies that the regional high-strain deformation had ceased before the time of the reactions orthopyroxene+sillimanite+quartz=cordierite, orthopyroxene+sillimanite=cordierite+sapphirine±spinel, garnet=orthopyroxene+cordierite+sapphirine and garnet+quartz=orthopyroxene+cordierite. In contrast to the peak metamorphic high-strain deformation, the post-peak metamorphic structural evolution was characterized by low-strain and localized deformations such as F_<n+1> gentle folding, emplacement of clinopyroxene pegmatites and basic dykes, and local shearing in the N-S compressional and E-W extensional field. In response to subsequent N-S compression, ductile thrusting had taken place. The last structural event at Rundvagshetta was represented by the emplacement of felsic pegmatites.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00002753","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA1072335X","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":"Institute of Geology and Paleontology, Faculty of Science, Tohoku University"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"Research School of Earth Sciences, Australian National University"},{"subitem_text_language":"en","subitem_text_value":"Department of Earth Science, Faculty of Science, Ehime University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1994-09-01"}],"displaytype":"detail","filename":"KJ00002368383.pdf","filesize":[{"value":"2.9 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002368383","url":"https://nipr.repo.nii.ac.jp/record/2753/files/KJ00002368383.pdf"},"version_id":"6676f567-4da5-4b23-8437-39e503430ebc"}]},"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":"STRUCTURAL EVOLUTION OF RUNDVAGSHETTA REGION, LUTZOW-HOLM BAY, EAST ANTARCTICA","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"STRUCTURAL EVOLUTION OF RUNDVAGSHETTA REGION, LUTZOW-HOLM BAY, EAST ANTARCTICA"}]},"item_type_id":"1","owner":"4","path":["421"],"pubdate":{"attribute_name":"公開日","attribute_value":"1994-09-01"},"publish_date":"1994-09-01","publish_status":"0","recid":"2753","relation_version_is_last":true,"title":["STRUCTURAL EVOLUTION OF RUNDVAGSHETTA REGION, LUTZOW-HOLM BAY, EAST ANTARCTICA"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:43:02.802311+00:00"}
