Two alternative models were applied to distinguish igneous processes from metamorphic features; they are fractional crystallization and diffusive modification of primary composition. It was clarified that chemical zoning of olivines in Y-791717 has been formed by a diffusion process, suggesting that this meteorite has been thermally metamorphosed. Thermal metamorphism of Y-791717 we have shown is consistent with that proposed on the basis of thermoluminescence investigation. A diffusion model also allows us to examine its thermal history in a quantitative way. Using a diffusion model, we have most successfully reproduced measured zoning profiles in isolated and chondrule olivine grains from Y-791717 in the temperature range 800-300℃. The temperature range is broadly consistent with the previously proposed peak metamorphic temperatures for CO3 chondrites.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00005897","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":"AA11182426","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":"Mineralogical Institute, Graduate School of Science, University of Tokyo/Mineralogical Institute, Graduate School of Science, University of Tokyo/Mineralogical Institute, Graduate School of Science, University of Tokyo/Mineralogical Institute, Graduate School of Science, University of Tokyo"}]},"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":"KJ00000040889.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000040889","url":"https://nipr.repo.nii.ac.jp/record/5897/files/KJ00000040889.pdf"},"version_id":"86391fd4-585b-4b62-8418-c3328dcf70b9"}]},"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":"Chemical zoning of olivines in the Yamato-791717 CO3 chondrite","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Chemical zoning of olivines in the Yamato-791717 CO3 chondrite"}]},"item_type_id":"1","owner":"4","path":["774"],"pubdate":{"attribute_name":"公開日","attribute_value":"1997-09-01"},"publish_date":"1997-09-01","publish_status":"0","recid":"5897","relation_version_is_last":true,"title":["Chemical zoning of olivines in the Yamato-791717 CO3 chondrite"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:08:54.415857+00:00"}
