The weathering has affected the Sm-Nd isotopic system. Acid-washed pyroxenes, whole rock and quenched glass samples define a Sm-Nd isochron age of 472±47 (±2σ) Ma and a high initial εNd value of +36.9±2.2 (±2σ). Both values are indisguishable from those reported for the other olivine-phyric depleted shergottite DaG 476. The Rb-Sr system of Y980459 shows even more terrestrial disturbance. The same acid-washed samples, which have a narrow Rb/Sr variation of only～10%, do not yield an Rb-Sr isochron. However, the weighted average of nine samples yields a good initial ^(87)Sr/^(86)Sr ratio value of 0.701384±0.000021 (±2σ) at 472Ma. This value is only slightly higher, by 1-2 ε-units, than that estimated from plagioclase data for DaG 476. Calculations for a two-stage model for Sr and Nd isotopic evolution indicate that Y980459 came from a depleted mantle reservoir with ^(147)Sm/^(144)Nd=～0.266 and ^(87)Rb/^(86)Sr=～0.04, similar to the DaG 476 source. A three-stage model calculation suggests that the REE abundances and Nd isotopic systematics of Y980459 could be produced by partial melting of high ^(147)Sm/^(144)Nd garnet-rich residues which were formed after the extraction of LREE-rich, nakhlite-like melts from a postulated garnet-clinopyroxene-olivine source having ^(147)Sm/^(144)Nd=～0.235.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00006064","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":"Lockheed-Martin Space Operations/KR, NASA Johnson Space Center/Lockheed-Martin Space Operations/Mail Code C-23, Hernandez Engineering Co./Antarctic Meteorite Research Center, National Institute of Polar Research"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2005-03-01"}],"displaytype":"detail","filename":"KJ00002499449.pdf","filesize":[{"value":"4.3 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002499449","url":"https://nipr.repo.nii.ac.jp/record/6064/files/KJ00002499449.pdf"},"version_id":"a3445a99-c08f-4292-a10f-805152154cab"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Yamato 980459, Rb-Sr, Sm-Nd, age, petrogenesis, nakhlite, depleted shergottite","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Rb-Sr and Sm-Nd dating of olivine-phyric shergottite Yamato 980459: Petrogenesis of depleted shergottites","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Rb-Sr and Sm-Nd dating of olivine-phyric shergottite Yamato 980459: Petrogenesis of depleted shergottites"}]},"item_type_id":"1","owner":"4","path":["782"],"pubdate":{"attribute_name":"公開日","attribute_value":"2005-03-01"},"publish_date":"2005-03-01","publish_status":"0","recid":"6064","relation_version_is_last":true,"title":["Rb-Sr and Sm-Nd dating of olivine-phyric shergottite Yamato 980459: Petrogenesis of depleted shergottites"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:06:44.075788+00:00"}
