The diagnostic assemblage in the Austhamaren calc-silicate is garnet (Grt)-quartz (Qtz)-wollastonite (Wo)-calcite (Cal), whereas Wo-plagioclase (Pl)-scapolite (Scp)-Qtz and Wo-Cal-Scp-Qtz are characteristic assemblages in the Eremitten gneiss. Wollastonite and calcite are nearly end member CaSiO_3 and CaCO_3. The other major phases approach the calcic end members : garnet is 80-91mole% grossular, plagioclase is An_<88-94>, and scapolite 77-83mole% meionite. Clinopyroxene is hedenbergite (Fe/(Fe+Mg)=0.50-0.67). The reactions Grt+Qtz=Wo+An and Grt+CO_2=Wo+Scp+Cal relate the assemblages in the Austhamaren and Eremitten samples. The two assemblages could be interepreted to result from a regional pressure decrease from Austhamaren in the north to Eremitten in the south. An alternative interpretation is that the Eremitten Wo-Scp assemblages formed at somewhat higher CO_2 activities, and Wo-An, at a slightly higher bulk Na/Ca ratio, compared to the Austhamaren assemblage. X_<CO_2>/(CO_2+H_2O) in the associated fluid phase) is estimated to have been buffered at <0.3 in the Eremitten rock and at 0.1-0.2 in the Austhamaren rock (for T=760-800℃, P=7-8kbar). X_<CO_2> remained low during a nearisobaric temperature decrease to T&le;600℃ following peak conditions at Eremitten when garnet selvages developed around wollastonite, scapolite, and plagioclase and scapolite was partially replaced by Pl+Cal+K-feldspar symplectite.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00002719","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":"Department of Geological Sciences, College of Liberal Arts, Okayama University"},{"subitem_text_language":"en","subitem_text_value":"Department of Geological Sciences, University of Maine"},{"subitem_text_language":"en","subitem_text_value":"Geological Survey of Japan"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1993-09-01"}],"displaytype":"detail","filename":"KJ00002368349.pdf","filesize":[{"value":"2.3 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002368349","url":"https://nipr.repo.nii.ac.jp/record/2719/files/KJ00002368349.pdf"},"version_id":"51ad4ee3-46ad-437d-aa94-4aa0eb03cf6b"}]},"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":"CONTRASTING MINERAL ASSOCIATIONS BETWEEN TWO WOLLASTONITE-BEARING CALC-SILICATE GNEISSES, EASTERN SØR RONDANE MOUNTAINS, ANTARCTICA","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"CONTRASTING MINERAL ASSOCIATIONS BETWEEN TWO WOLLASTONITE-BEARING CALC-SILICATE GNEISSES, EASTERN SØR RONDANE MOUNTAINS, ANTARCTICA"}]},"item_type_id":"1","owner":"4","path":["420"],"pubdate":{"attribute_name":"公開日","attribute_value":"1993-09-01"},"publish_date":"1993-09-01","publish_status":"0","recid":"2719","relation_version_is_last":true,"title":["CONTRASTING MINERAL ASSOCIATIONS BETWEEN TWO WOLLASTONITE-BEARING CALC-SILICATE GNEISSES, EASTERN SØR RONDANE MOUNTAINS, ANTARCTICA"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:43:33.597361+00:00"}
