Petrological and geochemical analyses of chondrites have suggested that secondary alteration phases formed at low temperatures (<300 °C) by fluid-rock interaction where reduced and oxidized Vigarano type Carbonaceous (CV) chondrites witness different physicochemical conditions. From a thermodynamical survey of Ca-Fe-rich secondary phases in CV3 chondrites including silica activity (<jats:italic>a</jats:italic>SiO<jats:sub>2</jats:sub>), here we show that the classical distinction between reduced and oxidized chondrites is no longer valid and that their Ca-Fe-rich secondary phases formed in similar reduced conditions near the iron-magnetite redox buffer at low <jats:italic>a</jats:italic>SiO<jats:sub>2</jats:sub> (log<jats:italic>(a</jats:italic>SiO<jats:sub>2</jats:sub>) <−1) and moderate temperature (210–610 °C). The various lithologies in CV3 chondrites are inferred to be fragments of an asteroid percolated heterogeneously via porous flow of hydrothermal fluid. Putative ‘onion shell’ structures are not anymore a requirement for the CV parent body crust.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670318699138304","@type":"Researcher","foaf:name":[{"@value":"Clément Ganino"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670318699138305","@type":"Researcher","foaf:name":[{"@value":"Guy Libourel"}]}],"publication":{"publicationIdentifier":[{"@type":"EISSN","@value":"20411723"}],"prism:publicationName":[{"@value":"Nature Communications"}],"dc:publisher":[{"@value":"Springer Science and Business Media LLC"}],"prism:publicationDate":"2017-08-15","prism:volume":"8","prism:number":"1","prism:startingPage":"261"},"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/s41467-017-00293-1.pdf"},{"@id":"https://www.nature.com/articles/s41467-017-00293-1"}],"createdAt":"2017-08-07","modifiedAt":"2022-12-22","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050012570393147008","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Asteroid Ryugu before the Hayabusa2 encounter"},{"@value":"International regolith science group (IRSG) in Hayabusa2 project, asteroid ryugu before the hayabusa2 encounter"}]},{"@id":"https://cir.nii.ac.jp/crid/1360285710774750976","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Origin of the metamorphosed clasts in the <scp>CV</scp>3 carbonaceous chondrite breccias of Graves Nunataks 06101, Vigarano, Roberts Massif 04143, and Yamato‐86009"}]},{"@id":"https://cir.nii.ac.jp/crid/1360306905177044224","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Metasomatic Alteration of Type 3 Ordinary and Carbonaceous Chondrites"}]},{"@id":"https://cir.nii.ac.jp/crid/1360576118683326336","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Origin of hydrogen isotopic variations in chondritic water and organics"}]},{"@id":"https://cir.nii.ac.jp/crid/1360584340708851200","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Aqueous alteration in icy planetesimals: The effect of outward transport of gaseous hydrogen"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1038/s41467-017-00293-1"},{"@type":"CROSSREF","@value":"10.1186/s40645-018-0237-y_references_DOI_XfwpsohHao0BsIB6ZzI8zRgt2f3"},{"@type":"CROSSREF","@value":"10.1111/maps.13272_references_DOI_XfwpsohHao0BsIB6ZzI8zRgt2f3"},{"@type":"CROSSREF","@value":"10.1007/s11214-025-01135-z_references_DOI_XfwpsohHao0BsIB6ZzI8zRgt2f3"},{"@type":"CROSSREF","@value":"10.1016/j.epsl.2021.117008_references_DOI_XfwpsohHao0BsIB6ZzI8zRgt2f3"},{"@type":"CROSSREF","@value":"10.1016/j.gca.2024.03.022_references_DOI_XfwpsohHao0BsIB6ZzI8zRgt2f3"}]}
