However, relics of these large proto-planets are yet to be found. Ureilites are one of the main families of achondritic meteorites and their parent body is believed to have been catastrophically disrupted by an impact during the first 10 million years of the solar system. Here we studied a section of the Almahata Sitta ureilite using transmission electron microscopy, where large diamonds were formed at high pressure inside the parent body. We discovered chromite, phosphate, and (Fe,Ni)-sulfide inclusions embedded in diamond. The composition and morphology of the inclusions can only be explained if the formation pressure was higher than 20 GPa. Such pressures suggest that the ureilite parent body was a Mercury- to Mars-sized planetary embryo.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670319144472705","@type":"Researcher","foaf:name":[{"@value":"Farhang Nabiei"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319144472576","@type":"Researcher","foaf:name":[{"@value":"James Badro"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319144472577","@type":"Researcher","foaf:name":[{"@value":"Teresa Dennenwaldt"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319144472581","@type":"Researcher","foaf:name":[{"@value":"Emad Oveisi"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319144472578","@type":"Researcher","foaf:name":[{"@value":"Marco Cantoni"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319144472579","@type":"Researcher","foaf:name":[{"@value":"Cécile Hébert"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319144472704","@type":"Researcher","foaf:name":[{"@value":"Ahmed El Goresy"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319144472580","@type":"Researcher","foaf:name":[{"@value":"Jean-Alix Barrat"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319144472706","@type":"Researcher","foaf:name":[{"@value":"Philippe Gillet"}]}],"publication":{"publicationIdentifier":[{"@type":"EISSN","@value":"20411723"}],"prism:publicationName":[{"@value":"Nature Communications"}],"dc:publisher":[{"@value":"Springer Science and Business Media LLC"}],"prism:publicationDate":"2018-04-17","prism:volume":"9","prism:number":"1","prism:startingPage":"1327"},"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/s41467-018-03808-6.pdf"},{"@id":"https://www.nature.com/articles/s41467-018-03808-6"}],"createdAt":"2018-03-29","modifiedAt":"2022-12-20","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360290617488508416","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Nearly Carbon‐Saturated Magma Oceans in Planetary Embryos During Core Formation"}]},{"@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":"10.1038/s41467-018-03808-6"},{"@type":"CROSSREF","@value":"10.1029/2021gl092389_references_DOI_Y58nNSR7cBfGeOiz31h3M3fPcVI"},{"@type":"CROSSREF","@value":"10.1186/s40645-021-00451-6_references_DOI_Y58nNSR7cBfGeOiz31h3M3fPcVI"}]}
