Coolidge and Y-693 are members of the CV clan based on refractory lithophile abundances. Coolidge has significantly depleted volatile element abundances relative to CV3 chondrites and is tentatively classified as CV4. Y-693 is compositionally indistinguishable from the oxidized subgroup CV3 chondrites, showing no significant depletion of volatile element abundances, in conflict with the petrographic data indicating type 5; the chondrite may be heterogeneous. Compositional and petrographic data for Karoonda and ALH82135 suggest they form a grouplet, part of a clan with refractory lithophile abundances intermediate between those of the CM-CO and CV clans. Compositional classification of the severely weathered PCA82500 is difficult because of the scatter of data. It is probably closely related to Karoonda and ALH82135.","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 Geophysics and Planetary Physics, University of California"}]},"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":"KJ00000012683.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"url":"https://nipr.repo.nii.ac.jp/record/2130/files/KJ00000012683.pdf"},"version_id":"0830853d-2785-4ab3-8fe4-ca85e52154f9"}]},"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":"Compositional comparisons of metamorphosed carbonaceous chondrites","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Compositional comparisons of metamorphosed carbonaceous chondrites","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":"2130","relation_version_is_last":true,"title":["Compositional comparisons of metamorphosed carbonaceous chondrites"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:51:32.995828+00:00"}
