The new mineral was approved by the International Mineralogical Association (IMA 2016-085) and named hemleyite in honour of Russell J. Hemley. It was discovered in an unmelted portion of the heavily shocked L6 Suizhou chondrite closely associated to olivine, clinoenstatite and Fe-bearing pyroxene with a composition nearly identical to that of hemleyite. We also report the first single-crystal X-ray diffraction study of a Si-bearing, ilmenite-structured phase. The fact that hemleyite formed in a meteorite exposed to high pressures (<20 GPa) and temperatures (<2000 °C) during impact-induced shocks indicates that it could play a crucial role at the bottom of the Earth’s mantle transition zone and within the uppermost lower mantle.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381418521004069377","@type":"Researcher","foaf:name":[{"@value":"Luca Bindi"}]},{"@id":"https://cir.nii.ac.jp/crid/1381418521004069376","@type":"Researcher","foaf:name":[{"@value":"Ming Chen"}]},{"@id":"https://cir.nii.ac.jp/crid/1381418521004069378","@type":"Researcher","foaf:name":[{"@value":"Xiande Xie"}]}],"publication":{"publicationIdentifier":[{"@type":"EISSN","@value":"20452322"}],"prism:publicationName":[{"@value":"Scientific Reports"}],"dc:publisher":[{"@value":"Springer Science and Business Media LLC"}],"prism:publicationDate":"2017-02-15","prism:volume":"7","prism:number":"1","prism:startingPage":"42674"},"reviewed":"false","dc:rights":["https://creativecommons.org/licenses/by/4.0","https://creativecommons.org/licenses/by/4.0"],"url":[{"@id":"https://www.nature.com/articles/srep42674"},{"@id":"https://www.nature.com/articles/srep42674.pdf"}],"createdAt":"2017-02-15","modifiedAt":"2024-06-22","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050005508516260736","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Poirierite, a dense metastable polymorph of magnesium iron silicate in shocked meteorites"}]},{"@id":"https://cir.nii.ac.jp/crid/1050868693726604672","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Synthesis and Crystal Structure of Ilmenite-Type Silicate with Pyrope Composition"}]},{"@id":"https://cir.nii.ac.jp/crid/1360013168778930688","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Discovery of Elgoresyite, (Mg,Fe)<sub>5</sub>Si<sub>2</sub>O<sub>9</sub>: Implications for Novel Iron-Magnesium Silicates in Rocky Planetary Interiors"}]},{"@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/1360846643276521472","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"High‐pressure minerals in shocked meteorites"}]},{"@id":"https://cir.nii.ac.jp/crid/1390001206546754944","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Jadeite in shocked meteorites and its textural variations"}]},{"@id":"https://cir.nii.ac.jp/crid/1390854064974986880","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"A High-Pressure Mineral in a Meteorite and Collision Process Revealed by TEM"},{"@language":"ja","@value":"TEMで解き明かす隕石中の高圧鉱物と衝突過程"},{"@language":"ja-Kana","@value":"TEM デ トキアカス インセキ チュウ ノ コウアツ コウブツ ト ショウトツ カテイ"}]},{"@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"}]},{"@id":"https://cir.nii.ac.jp/crid/2050588892104880128","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Can quasicrystals survive in planetary collisions?"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1038/srep42674"},{"@type":"CROSSREF","@value":"10.1038/s43247-020-00090-7_references_DOI_BLskgaaoBxS8ZJwxBxxmX5wK4st"},{"@type":"CROSSREF","@value":"10.1021/acsearthspacechem.1c00157_references_DOI_BLskgaaoBxS8ZJwxBxxmX5wK4st"},{"@type":"CROSSREF","@value":"10.1186/s40645-021-00421-y_references_DOI_BLskgaaoBxS8ZJwxBxxmX5wK4st"},{"@type":"CROSSREF","@value":"10.3390/solids5030026_references_DOI_BLskgaaoBxS8ZJwxBxxmX5wK4st"},{"@type":"CROSSREF","@value":"10.1111/maps.13608_references_DOI_BLskgaaoBxS8ZJwxBxxmX5wK4st"},{"@type":"CROSSREF","@value":"10.1111/maps.12902_references_DOI_BLskgaaoBxS8ZJwxBxxmX5wK4st"},{"@type":"CROSSREF","@value":"10.2465/jmps.170329_references_DOI_BLskgaaoBxS8ZJwxBxxmX5wK4st"},{"@type":"CROSSREF","@value":"10.4131/jshpreview.31.157_references_DOI_BLskgaaoBxS8ZJwxBxxmX5wK4st"},{"@type":"CROSSREF","@value":"10.1186/s40645-021-00451-6_references_DOI_BLskgaaoBxS8ZJwxBxxmX5wK4st"}]}
