Natl Inst. Polar Res., Spec. Issue, 35,18,1984). The clast sample (Y-791197,96) shows a plateau ^<40>Ar-^<39>Ar age of 4065±93 Ma at higher temperatures, which corresponds to typical age groups obtained for lunar rocks of highland origin. The matrix sample (Y-791197,97) contains a large amount of trapped Ar (^<40>Ar : &acd;9×(10)^<-4>(cm)^3STP/g) with the ^<40>Ar/^<36>Ar ratio of about 2.5 at higher temperatures, which implies that the trapped Ar is mostly of solar wind origin. This makes it difficult to estimate a reasonable ^<40>Ar-^<39>Ar age for this portion. The present result supports a presumption that Y-791197 originated from the moon's surface as a lunar highland breccia.","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":"Geophysical Institute, Faculty of Science, University of Tokyo/Department of Earth Sciences, Faculty of Science, Yamagata University"}]},"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":"KJ00000012511.pdf","filesize":[{"value":"996.3 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"url":"https://nipr.repo.nii.ac.jp/record/1957/files/KJ00000012511.pdf"},"version_id":"085aa6df-f29d-4d9b-b4e3-047b6a781ace"}]},"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":"40Ar-39Ar analyses of an Antarctic meteorite Yamato-791197 of probable lunar origin","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"40Ar-39Ar analyses of an Antarctic meteorite Yamato-791197 of probable lunar origin","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":"1957","relation_version_is_last":true,"title":["40Ar-39Ar analyses of an Antarctic meteorite Yamato-791197 of probable lunar origin"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:48:11.532877+00:00"}
