These anorthites are 1 to 3 cm in size and often contain several corroded Mg-olivine inclusions. The megacrysts generally range from An<jats:sub>94</jats:sub>Ab<jats:sub>4</jats:sub>Ot<jats:sub>2</jats:sub> to An<jats:sub>89</jats:sub>Ab<jats:sub>6</jats:sub>Ot<jats:sub>5</jats:sub> (Ot: other minor end-members, including CaFeSi<jats:sub>3</jats:sub>O<jats:sub>8</jats:sub>, CaMgSi<jats:sub>3</jats:sub>O<jats:sub>8</jats:sub>, AlAl<jats:sub>3</jats:sub>SiO<jats:sub>8</jats:sub>, □Si<jats:sub>4</jats:sub>O<jats:sub>8</jats:sub>) and show no chemical zoning. They often show parting. Redclouded megacrysts contain microcrystals of native copper with a distribution reminiscent of the shape of a planetary nebula. Hydrocarbons are also present, both in the anorthite megacrysts and in the olivines included within them. Implications of lateral variations in the Fe/Mg ratio of the included olivines, in Sr-content and in Sr-isotope ratio of the anorthite megacrysts with respect to the Japanese island arc, relate to mixing of crustal components and subducted slab-sediments into the basaltic magmas.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699995361213697","@type":"Researcher","foaf:name":[{"@value":"Mitsuyoshi Kimata"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699995361213700","@type":"Researcher","foaf:name":[{"@value":"Norimasa Nishida"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699995361213696","@type":"Researcher","foaf:name":[{"@value":"Masahiro Shimizu"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699995361213698","@type":"Researcher","foaf:name":[{"@value":"Shizuo Saito"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699995361213701","@type":"Researcher","foaf:name":[{"@value":"Tomoaki Matsui"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699995361213699","@type":"Researcher","foaf:name":[{"@value":"Yoji Arakawa"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"0026461X"},{"@type":"EISSN","@value":"14718022"},{"@type":"PISSN","@value":"http://id.crossref.org/issn/0026461X"}],"prism:publicationName":[{"@value":"Mineralogical Magazine"}],"dc:publisher":[{"@value":"Mineralogical Society"}],"prism:publicationDate":"1995-03","prism:volume":"59","prism:number":"394","prism:startingPage":"1","prism:endingPage":"14"},"reviewed":"false","dc:rights":["https://www.cambridge.org/core/terms"],"url":[{"@id":"https://www.cambridge.org/core/services/aop-cambridge-core/content/view/S0026461X00018855"}],"createdAt":"2006-12-07","modifiedAt":"2021-02-04","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360306905149483776","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Extraordinary Crystals of Natural Minerals in Mining Sites and Volcanoes"}]},{"@id":"https://cir.nii.ac.jp/crid/1390001206524978432","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Identification of microinclusions in the nanometer dimension by electron microprobe analysis.
