Alumina-free tetragonal garnet exists in the pressure range from 16 to 23.5 GPa. The compositional range of the tetragonal garnet phase extends from pure MgSiO 3  to (Mg 0.76 Fe 0.24 )SiO 3  at 18.2 GPa and 1800°C. The sequence of the phase transitions in Mg-rich part of this system at 1800°C is: clinopyroxene→17GPatetragonal garnet→22.5GPailmenite→23GPaMg-perovskite. The lattice constants of tetragonal garnet increase with increasing iron content from a = 11.517 ± 0.002Aandc = 11.435 ± 0.003Afor MgSiO 3 toa = 11.543 ± 0.002A and c  = 11.476 ± 0.003A for (Mg 0.76 Fe 0.24 )SiO 3 . Cubic garnet was not observed in the pressure and temperature range studied in this work. The alumina-free tetragonal garnet observed in this study may exist in the harzbergite layer in the descending slab."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670318761155073","@type":"Researcher","foaf:name":[{"@value":"Eiji Ohtani"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670318761154944","@type":"Researcher","foaf:name":[{"@value":"Naohiro Kagawa"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670318761155072","@type":"Researcher","foaf:name":[{"@value":"Kiyoshi Fujino"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"0012821X"}],"prism:publicationName":[{"@value":"Earth and Planetary Science Letters"}],"dc:publisher":[{"@value":"Elsevier BV"}],"prism:publicationDate":"1991-02","prism:volume":"102","prism:number":"2","prism:startingPage":"158","prism:endingPage":"166"},"reviewed":"false","dc:rights":["https://www.elsevier.com/tdm/userlicense/1.0/","https://www.elsevier.com/legal/tdmrep-license"],"url":[{"@id":"https://api.elsevier.com/content/article/PII:0012821X91900053?httpAccept=text/xml"},{"@id":"https://api.elsevier.com/content/article/PII:0012821X91900053?httpAccept=text/plain"}],"createdAt":"2002-11-11","modifiedAt":"2025-09-05","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050301927790416512","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Discovery of natural MgSiO3 tetragonal garnet in a shocked chondritic meteorite"},{"@value":"Discovery of natural MgSiO\n            <sub>3</sub>\n            tetragonal garnet in a shocked chondritic meteorite"}]},{"@id":"https://cir.nii.ac.jp/crid/1360002216855511936","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Jadeite in Chelyabinsk meteorite and the nature of an impact event on its parent body"}]},{"@id":"https://cir.nii.ac.jp/crid/1360005517197820032","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Phase relations of MgSiO3-FeSiO3 system up to 64 GPa and 2300 K using multianvil apparatus with sintered diamond anvils"}]},{"@id":"https://cir.nii.ac.jp/crid/1360285707402294400","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"High pressure generation using scaled-up Kawai-cell"}]},{"@id":"https://cir.nii.ac.jp/crid/1360285707402309120","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Sound velocities measurement on MgSiO3 akimotoite at high pressures and high temperatures with simultaneous in situ X-ray diffraction and ultrasonic study"}]},{"@id":"https://cir.nii.ac.jp/crid/1360285707458982016","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Evidence for phase transitions in mineral inclusions in superdeep diamonds of the São Luiz deposit (Brazil)"}]},{"@id":"https://cir.nii.ac.jp/crid/1360567182435711744","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"“Spherulite-like” jadeite growth in shock-melt veins of the Novosibirsk H5/6 chondrite"}]},{"@id":"https://cir.nii.ac.jp/crid/1360572092406786944","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Systematic investigations of high‐pressure polymorphs in shocked ordinary chondrites"}]},{"@id":"https://cir.nii.ac.jp/crid/2050025942153536512","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Natural and experimental high-pressure, shock-produced terrestrial and extraterrestrial materials"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1016/0012-821x(91)90005-3"},{"@type":"OPENAIRE","@value":"doi_dedup___::8b6d5b8609b8461c23837cdd2986b5ba"},{"@type":"CROSSREF","@value":"10.1038/srep05033_references_DOI_BPj8qb3GQLt9rEekMFQGQrADGP6"},{"@type":"CROSSREF","@value":"10.1016/j.rgg.2015.01.021_references_DOI_BPj8qb3GQLt9rEekMFQGQrADGP6"},{"@type":"CROSSREF","@value":"10.1126/sciadv.1501725_references_DOI_BPj8qb3GQLt9rEekMFQGQrADGP6"},{"@type":"CROSSREF","@value":"10.1111/maps.13608_references_DOI_BPj8qb3GQLt9rEekMFQGQrADGP6"},{"@type":"CROSSREF","@value":"10.1016/j.pepi.2011.08.001_references_DOI_BPj8qb3GQLt9rEekMFQGQrADGP6"},{"@type":"CROSSREF","@value":"10.1186/s40645-021-00451-6_references_DOI_BPj8qb3GQLt9rEekMFQGQrADGP6"},{"@type":"CROSSREF","@value":"10.1016/j.rgg.2016.04.012_references_DOI_BPj8qb3GQLt9rEekMFQGQrADGP6"},{"@type":"CROSSREF","@value":"10.1016/j.pepi.2019.106297_references_DOI_BPj8qb3GQLt9rEekMFQGQrADGP6"},{"@type":"CROSSREF","@value":"10.1016/j.pepi.2013.06.005_references_DOI_BPj8qb3GQLt9rEekMFQGQrADGP6"}]}
