The δ^<18>O of calcite cores and most of the calcite grain boundaries are grouped around 17‰ while two analyses from the calcite-phlogopite grain boundary show depletion to -1‰. A corresponding δ^<13>C enrichment (only 0.7‰) is also observed. The δ^<13>C of graphite does not show any heterogeneity. The homogeneity of δ^<18>O and δ^<13>C of calcite (except for the local depletion) and δ^<13>C of graphite indicate that the marbles evolved through prograde and peak metamorphism with possible internal fluid buffering. The variations observed in carbon and oxygen isotopes can be ascribed to devolatilization reactions. The peak metamorphic temperature estimate by carbon isotope thermometry gave 760℃, consistent with regional peak metamorphic conditions. The local occurrence of isotopic heterogeneity on the calcite-phlogopite boundary suggests that there was meteoric water infiltration during the late stages of metamorphic history. Millimeter scale gigantic oxygen isotopic heterogeneity is observed for the first time in metamorphic rocks. The mechanism of isotope exchange invloved is unclear in the present study, but may indicate a process of fluid flow through preferential grain boundaries and by solution-reprecipitation or diffusion.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00002848","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 Geosciences, Osaka City University"},{"subitem_text_language":"en","subitem_text_value":"Department of Biology and Geosciences, Shizuoka University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1997-09-01"}],"displaytype":"detail","filename":"KJ00002368121.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002368121","url":"https://nipr.repo.nii.ac.jp/record/2848/files/KJ00002368121.pdf"},"version_id":"b50e00be-166a-410d-b413-afd796455512"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Skallen marbles","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"oxygen isotopes","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"calcite","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"meteoric water","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"fluid infiltration","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"METEORIC WATER INFILTRATION IN SKALLEN MARBLES, EAST ANTARCTICA : OXYGEN ISOTOPIC EVIDENCE","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"METEORIC WATER INFILTRATION IN SKALLEN MARBLES, EAST ANTARCTICA : OXYGEN ISOTOPIC EVIDENCE"}]},"item_type_id":"1","owner":"4","path":["424"],"pubdate":{"attribute_name":"公開日","attribute_value":"1997-09-01"},"publish_date":"1997-09-01","publish_status":"0","recid":"2848","relation_version_is_last":true,"title":["METEORIC WATER INFILTRATION IN SKALLEN MARBLES, EAST ANTARCTICA : OXYGEN ISOTOPIC EVIDENCE"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:41:37.362345+00:00"}
