The results indicate that Y-82104 and Y-693 should be included with the CK carbonaceous chondrites. Y-82104 and Y-693 are remarkably similar in mineralogy and texture (e.g., virtually identical compositions of olivines, Fa 29.2±0.4vs. Fa 29.4±0.7,respectively). Thus, they are probably paired. The compositional homogeneity of olivine and pyroxene and degree of recrystallization of olivine and plagioclase are consistent with Y-82104 and Y-693 being petrologic type 5. Y-82002 differs from most CK chondrites in mineralogy and petrology, but is similar to Carlisle Lakes-type chondrites which were recently proposed to be a new grouplet of chondrites (A. E. RUBIN and G. W. KALLEMEYN, Geochim. Cosmochim., 53,3035,1989). We believe that Y-82002 is a member of this grouplet. Y-82002 was previously classified as petrologic type 5,but the relatively inhomogeneous compositions of olivine (e. g., Fa 35.1±5.1 for chondrules) and low degree of recrystallization of olivine and plagioclase suggest that Y-82002 should be classified as petrologic type 3.8-3.9.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004609","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":"AA10784627","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":"Mineralogical Institute, Faculty of Science, University of Tokyo/Department of Earth Sciences, Faculty of Science, Kobe University/Mineralogical Institute, Faculty of Science, 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":"1993-05-01"}],"displaytype":"detail","filename":"KJ00000036415.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000036415","url":"https://nipr.repo.nii.ac.jp/record/4609/files/KJ00000036415.pdf"},"version_id":"8ec6a51f-541a-491c-aa74-df5b6e4e0c5c"}]},"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":"Mineralogy and petrology of the CK chondrites Yamato-82104, Yamato-693 and a Carlisle Lakes-type chondrite Yamato-82002","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Mineralogy and petrology of the CK chondrites Yamato-82104, Yamato-693 and a Carlisle Lakes-type chondrite Yamato-82002"}]},"item_type_id":"1","owner":"4","path":["590"],"pubdate":{"attribute_name":"公開日","attribute_value":"1993-05-01"},"publish_date":"1993-05-01","publish_status":"0","recid":"4609","relation_version_is_last":true,"title":["Mineralogy and petrology of the CK chondrites Yamato-82104, Yamato-693 and a Carlisle Lakes-type chondrite Yamato-82002"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:18:32.178957+00:00"}
