The xenoliths show multiple-episodes of metasomatism resulting in formation of the veined metasomites and the equilibrated metasomites. The metasomatized xenoliths are characterized texturally and chemically by co-existence of Ti-augite, phlogopitic mica, pargasitic and kaersutitic amphiboles, Al-spinel and apatite with the upper mantle olivine, pyroxenes, and Cr-spinel. Ti-, Al-, Fe- and Ca- enrichments and Si-, Cr- and Mg-depletions observed in the metasomatic clinopyroxenes indicate that the metasomatism was probably generated by an alkaline silicate melt reacting with solid phases of the upper mantle. Ti- and Fe-enrichments and Al-depletion in the metasomatic clinopyroxenes can be also detected as a separate episode of metasomatism different from the above veined-type reactions. Texturally and chemically equilibrated phlogopites and pargasites in the mantle-derived xenoliths provide a different type metasomatism, showing conspicuous depletions in TiO_2,Al_2O_3,Cr_2O_3,and K_2O, and enrichments in SiO_2 and Na_2O.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00002563","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 Geology and Mineralogy, Faculty of Science, Hokkaido University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1988-09-01"}],"displaytype":"detail","filename":"KJ00002368153.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002368153","url":"https://nipr.repo.nii.ac.jp/record/2563/files/KJ00002368153.pdf"},"version_id":"7ccc5c9e-411f-4cde-b9d6-9103488eb659"}]},"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":"METASOMATIC VEINS AND MINERALS IN MANTLE-DERIVED XENOLITHS, ANTARCTICA","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"METASOMATIC VEINS AND MINERALS IN MANTLE-DERIVED XENOLITHS, ANTARCTICA"}]},"item_type_id":"1","owner":"4","path":["416"],"pubdate":{"attribute_name":"公開日","attribute_value":"1988-09-01"},"publish_date":"1988-09-01","publish_status":"0","recid":"2563","relation_version_is_last":true,"title":["METASOMATIC VEINS AND MINERALS IN MANTLE-DERIVED XENOLITHS, ANTARCTICA"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:45:29.921965+00:00"}
