The texture of Yamato-74010,-74011,-74013,-74037,-74097,-74136 and -74648 is unlike those of the other diogenites. It is not brecciated and texturally the pyroxene seems to have recrystallized to a granoblastic texture with small change in mineral composition. The chemical composition of the orthopyroxenes in these diogenites falls in the range (Ca)_<1.9> (Mg)_<75.1> (Fe)_<23.0> to (Ca)_<3.0> (Mg)_<71.0> (Fe)_<26.0>. The chemistry and textures of these diogenites are the same as those of the Yamato-6902 (b) diogenite previously reported. These Yamato diogenites may represent fragments of the same fall. Yamato-74159 is a polymict breccia which contains mineral and lithic clasts common to eucrites. The Yamato-74450 eucrite shows a variolitic texture, indicating a rapid solidification near the surface of its parent body. A brecciated part containing a pigeonite crystal with augite lamellae is also found in small amounts. The pyroxene trends of Yamato-74450 resemble those of the Pasamonte eucrite. The Yamato-74044 pallasite is the only stony-iron meteorite among the Yamato collection. A preliminary examination of the Yamato-75 meteorites identified one iron-rich diogenite and two eucritic polymict breccias. Yamato-75032 is the most Fe-rich of any known diogenite.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","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, Faculty of Science, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Department of Earth Sciences, Kobe University"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"Geological Institute, Faculty 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":"1978-02-01"}],"displaytype":"detail","filename":"KJ00000011859.pdf","filesize":[{"value":"2.3 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000011859","url":"https://nipr.repo.nii.ac.jp/record/886/files/KJ00000011859.pdf"},"version_id":"213d11ec-5fdd-48f1-8e99-22f11aa464f2"}]},"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":"A Preliminary Mineralogical Examination of the Yamato-74 Achondrites","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A Preliminary Mineralogical Examination of the Yamato-74 Achondrites","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["362"],"pubdate":{"attribute_name":"公開日","attribute_value":"1978-02-01"},"publish_date":"1978-02-01","publish_status":"0","recid":"886","relation_version_is_last":true,"title":["A Preliminary Mineralogical Examination of the Yamato-74 Achondrites"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:00:50.692363+00:00"}
