A thermodynamic model of plagioclase solid solution for the (CaAl,NaSi,KSi)(Fe3+,Al3+)Si2O8–Ca(Fe2+,Mg)Si3O8 system is proposed and is calibrated by regression analysis based on new and previously reported experimental data of Fe and Mg partitioning between plagioclase and silicate liquid, and reported thermodynamic properties of end members, ternary feldspar and silicate liquid. Using the derived thermodynamic model, FeOt, MgO content and Mg/(Fet+Mg) in plagioclase can be predicted from liquid composition with standard deviations of ±0.34 wt% (relative error =9%) and ±0.08 wt% (14%) and ±0.7 (8%) respectively. Calculated Fe3+–Al exchange chemical potentials of plagioclase,                   $${\\rm \\mu }_{{\\rm Fe}^{{\\rm 3 + }} \\left( {{\\rm Al}} \\right)_{{\\rm  - 1}} }^{{\\rm Pl}} $$                  agree with those calculated using reported thermodynamic models for multicomponent spinel,                   $${\\rm \\mu }_{{\\rm Fe}^{{\\rm 3 + }} \\left( {{\\rm Al}} \\right)_{{\\rm  - 1}} }^{{\\rm Sp}} $$                  and clinopyroxene,                   $${\\rm \\mu }_{{\\rm Fe}^{{\\rm 3 + }} \\left( {{\\rm Al}} \\right)_{{\\rm  - 1}} }^{{\\rm Cpx}} $$                  . The FeOt content of plagioclase coexisting with spinel or clinopyroxene is affected by Fe3+/(Fe3++Al) and Mg/(Fe+Mg) of spinel or clinopyroxene and temperature, while it is independent of the anorthite content of plagioclase. Three oxygen barometers based on the proposed model are investigated. Although the oxygen fugacities predicted by the plagioclase–liquid oxygen barometer are scattered, this study found that plagioclase–spinel–clinopyroxene–oxygen and plagioclase–olivine–oxygen equilibria can be used as practical oxygen barometers. As a petrological application, prediction of plagioclase composition and fO2 are carried out for the Upper Zone of the Skaergaard intrusion. The estimated oxygen fugacities are well below QFM buffer and consistent with the estimation of oxidization states in previous studies."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382262944580339072","@type":"Researcher","foaf:name":[{"@value":"Toru Sugawara"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00107999"},{"@type":"EISSN","@value":"14320967"},{"@type":"PISSN","@value":"http://id.crossref.org/issn/00107999"}],"prism:publicationName":[{"@value":"Contributions to Mineralogy and Petrology"}],"dc:publisher":[{"@value":"Springer Science and Business Media LLC"}],"prism:publicationDate":"2001-09","prism:volume":"141","prism:number":"6","prism:startingPage":"659","prism:endingPage":"686"},"reviewed":"false","dc:rights":["http://www.springer.com/tdm"],"url":[{"@id":"http://link.springer.com/content/pdf/10.1007/s004100100267.pdf"},{"@id":"http://link.springer.com/article/10.1007/s004100100267/fulltext.html"},{"@id":"http://link.springer.com/content/pdf/10.1007/s004100100267"}],"createdAt":"2010-09-30","modifiedAt":"2019-05-28","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050020209660477056","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"A brief review of single silicate crystal paleointensity: rock-magnetic characteristics, mineralogical backgrounds, methods and applications"}]},{"@id":"https://cir.nii.ac.jp/crid/1360004233291493504","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Constraints on the Source of the Martian Magnetic Anomalies Inferred From Relaxation Time of Remanent Magnetization"}]},{"@id":"https://cir.nii.ac.jp/crid/1360848658222311168","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Evolution of Magma Plumbing System in Miyakejima Volcano: Constraints From Melting Experiments"}]},{"@id":"https://cir.nii.ac.jp/crid/1361975843008224768","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Variation of Iron Species in Plagioclase Crystals by X‐ray Absorption Fine Structure Analysis"}]},{"@id":"https://cir.nii.ac.jp/crid/1390001206525835776","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Effect of secondary fluorescence on electron microprobe analysis of Fe in plagioclase."},{"@language":"ja","@value":"ＥＰＭＡによる斜長石中のＦｅ分析で生ずる二次蛍光効果について"},{"@language":"ja-Kana","@value":"EPMA ニ ヨル シャ チョウセキ チュウ ノ Fe ブンセキ デ ショウズル 2ジ ケイコウ コウカ ニ ツイテ"}]},{"@id":"https://cir.nii.ac.jp/crid/1390001206544842624","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Dacite-basalt magma interaction at Yakedake volcano, central Japan: petrographic and chemical evidence from the 2300 years B.P.
