Most of the features of the REE patterns are similar to those of the lunar highland samples, especially a kind of anorthosites. And the positive Ce-anomalies, shown in all REE patterns, appear characteristic of the lunar origin. The age obtained from the Rb-Sr system is 3.89±0.36 b. y. and it is considered that this age shows the time when these materials underwent an event, such as brecciation or impact melting. However, as a noticeable point, the initial ^<87>Sr/^<86>Sr is significantly low, even lower than BABI or LUNI. This result suggests that the source material of these samples might have had very low ^<87>Sr/^<86>Sr and Rb/Sr abundance ratios. The clast sample from the chip subordinate No. 109 has the distinct REE pattern and Sr-isotope ratio. Therefore, this clast can be considered to have been formed by different evolution process from the other samples, and was mingled later with them.","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":"Department of Chemistry, The University of Tokyo/Department of Chemistry, The University of Tokyo/Department of Chemistry, The 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":"KJ00000012509.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012509","url":"https://nipr.repo.nii.ac.jp/record/1955/files/KJ00000012509.pdf"},"version_id":"74c05f91-c679-459b-942f-d8b7b6b2a181"}]},"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":"REE adundances and Rb-Sr geochronology of Yamato-791197","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"REE adundances and Rb-Sr geochronology of Yamato-791197","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":"1955","relation_version_is_last":true,"title":["REE adundances and Rb-Sr geochronology of Yamato-791197"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:48:12.973033+00:00"}
