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", "download_preview_message": "", "file_order": 0, "filename": "KJ00000040889.pdf", "filesize": [{"value": "1.6 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_6", "mimetype": "application/pdf", "size": 1600000.0, "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"], "permalink_uri": "https://doi.org/10.15094/00005897", "pubdate": {"attribute_name": "公開日", "attribute_value": "1997-09-01"}, "publish_date": "1997-09-01", "publish_status": "0", "recid": "5897", "relation": {}, "relation_version_is_last": true, "title": ["Chemical zoning of olivines in the Yamato-791717 CO3 chondrite"], "weko_shared_id": 4}
