A-87272 is a monomict breccia, but the finegrained matrix is recrystallized to a granulitic texture with fine, rounded pyroxene crystals set in a plagioclase matrix. Large fragments of pyroxene are inverted to orthopyroxene with coarse exsolution lamellae on (001) and fine ones on (100). A-881388 contains a large, rounded opaque grain with a tail, and with an ilmenite-chromite-troilite-metal assemblage in fine-grained granulitic silicates, suggesting recrystallization. A-881394 is coarser grained than A-881388 and contains more magnesian pyroxene as in cumulate eucrites, but the plagioclase composition is extremely calcic (An 98) and the grains are composed with a few rounded grains. The A-881394 chromite, showing a pokilitic texture with rounded plagioclase and minor pyroxene, suggests a metamorphic texture. Our present interpretation for a common formation process among these eucrites is that despite their crystalline texture, they might have experienced extensive metamorphism after the initial crystallization in the early history of the crustal evolution.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00005910","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":"Research Institute, Chiba Institute of Technology/Ocean Research Institute, 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":"KJ00000040902.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000040902","url":"https://nipr.repo.nii.ac.jp/record/5910/files/KJ00000040902.pdf"},"version_id":"b06a0df6-61c6-4eaa-91a4-70c7eed0db0e"}]},"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":"Mineralogy of the Asuka 87 and 88 eucrites and crustal evolution of the HED parent body","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Mineralogy of the Asuka 87 and 88 eucrites and crustal evolution of the HED parent body"}]},"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":"5910","relation_version_is_last":true,"title":["Mineralogy of the Asuka 87 and 88 eucrites and crustal evolution of the HED parent body"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:08:43.273145+00:00"}
