Seven components are used in this study, six of which were used already for lunar plagioclases; that is, KAl(Si)_3O_8,NaAl(Si)_3O_8,Ca(Al)_2(Si)_2O_8,(Fe, Mg)(Al)_2(Si)_2O_8,Ca(Fe, Mg)(Al)_3O_8,[ ](Si)_4O_8 and M(MT)O_8,where [ ] means Na and/or Ca vacancy, M=K, Na, Ca, and T=Al, Si. The amounts of components Ca(Fe, Mg)(Si)_3O_8 and (Fe, Mg)(Al)_2(Si)_2O_8 significantly decrease with ordinary An-content. The highest contents of components Ca(Fe, Mg)(Si)_3O_8 and (Fe, Mg)(Al)_2(Si)_2O_8 in this study are obtained as 29(mol%) in the ALH-77307,85 (C3) and 11(mol%) in the Allende (CV3) chondrites, respectively. The largest values of components [ ](Si)_4O_8 and M (MT)O_8 are found in this study as 8(mol%) in the Juvinas eucrite and 12(mol%) in the Allende (CV3) chondrite, respectively. Lower Fe/(Fe+Mg) ratio is characteristic of chondrule in meteorite. The Plainview chondrite showing unique behavior of a considerable variation of the components may indicate a mixture of various parent materials. Small amounts of excess M cations (i.e. M(MT)O_8) are observed mainly in the exsolved regions of plagioclase crystal in meteorite (esp. the Juvinas eucrite and the Holbrook chondrite). A plot of each end-member abundance vs. Ca(Al)_2(Si)_2O_8 may be considered a useful indicator of the formation process of the meteorite.","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 Mineralogical Science and Geology, Faculty of Science, Yamaguchi University"},{"subitem_text_language":"en","subitem_text_value":"Department of Mineralogical Science and Geology, Faculty of Science, Yamaguchi University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1984-12-01"}],"displaytype":"detail","filename":"KJ00000012357.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012357","url":"https://nipr.repo.nii.ac.jp/record/1725/files/KJ00000012357.pdf"},"version_id":"9ccb3721-5911-4b5f-a395-e5167be3f26f"}]},"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":"Composition and structural substitution of meteoritic plagioclases (I)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Composition and structural substitution of meteoritic plagioclases (I)","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["389"],"pubdate":{"attribute_name":"公開日","attribute_value":"1984-12-01"},"publish_date":"1984-12-01","publish_status":"0","recid":"1725","relation_version_is_last":true,"title":["Composition and structural substitution of meteoritic plagioclases (I)"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:53:00.311534+00:00"}
