A rare brown pyroxene-rich clast (HPF) consists of hedenbergite, Ca-poor iron-rich pyroxene, plagioclase, fayalite, silica and ilmenite. This exotic component may be a differentiated product of the lunar crust or an iron-rich portion of a basalt. The evolutionary trend of Y-791197 from spinel troctolite to anorthosite in the An content vs. Mg/(Mg+Fe) diagram is similar to that of ALHA81005 and is located between the Mg-rich suite of rocks and ferroan anorthosite. It is difficult to prove that this trend represents a single differentiation and that the HPF clast is on the extension of this trend, because the data appear to define a trend of extremely steep slope. The glass in the matrix of ALHA81005 is devitrified on the TEM scale.","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 Sciences, University of Tokyo/Mineralogical Institute, Faculty of Sciences, University of Tokyo/Mineralogical Institute, Faculty of Sciences, 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":"1986-07-01"}],"displaytype":"detail","filename":"KJ00000012505.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"url":"https://nipr.repo.nii.ac.jp/record/1951/files/KJ00000012505.pdf"},"version_id":"71a0a06c-edcc-47f9-84f6-c526c582864b"}]},"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 Antarctic lunar meteorites and differentiated products of the lunar crust","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Mineralogy of Antarctic lunar meteorites and differentiated products of the lunar crust","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["395"],"pubdate":{"attribute_name":"公開日","attribute_value":"1986-07-01"},"publish_date":"1986-07-01","publish_status":"0","recid":"1951","relation_version_is_last":true,"title":["Mineralogy of Antarctic lunar meteorites and differentiated products of the lunar crust"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:48:17.147920+00:00"}
