Of eleven clasts from Y-791197,one is a very low-Ti (VLT) mare basalt, four are ferroan mafic lithologies that are either low-Ti mare basalts or polymict breccias with a large component of low-Ti mare basalt, three are ferroan anorthositic rocks, and three are magnesian granulitic breccias. In Y-82192 and -82193 magnesian clasts, most of which are polymict, are relatively more abundant. Of nine clasts from Y-82192,one is a possible low-Ti mare basalt, two are ferroan mafic lithologies that are either low-Ti mare basalts or polymict breccias with a large component of low-Ti mare basalt, and six are more magnesian polymict breccias. Of four clasts from Y-82193,three are magnesian polymict breccias and one may be a fragment of a pristine Mg-suite lithology. The presence of a significant mare basalt component in at least three of the four lunar meteorites is consistent with orbital geochemical data that suggest that the farside highlands have a 30% component of mare basalts that may predate the final heavy lunar bombardment. The lunar meteorites need not be derived from a source region near visible maria. Available data are insufficient to say whether all four lunar meteorites were derived from a single impact.","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":"Institute of Meteoritics, Department of Geology, University of New Mexico"},{"subitem_text_language":"en","subitem_text_value":"Institute of Meteoritics, Department of Geology, University of New Mexico"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1987-03-01"}],"displaytype":"detail","filename":"KJ00000012673.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012673","url":"https://nipr.repo.nii.ac.jp/record/2120/files/KJ00000012673.pdf"},"version_id":"fff697cd-1f0b-4453-8308-6ceede7d2037"}]},"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":"Mare basalt and other clasts in Yamato lunar meteorites Y-791197, -82192 and -82193","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Mare basalt and other clasts in Yamato lunar meteorites Y-791197, -82192 and -82193","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["400"],"pubdate":{"attribute_name":"公開日","attribute_value":"1987-03-01"},"publish_date":"1987-03-01","publish_status":"0","recid":"2120","relation_version_is_last":true,"title":["Mare basalt and other clasts in Yamato lunar meteorites Y-791197, -82192 and -82193"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:51:45.006953+00:00"}
