The surface mineralogy of dwarf planet Ceres appears to be dominated by products of rock–fluid interactions, such as phyllosilicates—some of which are NH4-bearing—and carbonates1–3. Elemental concentrations derived from the inferred mineral mixing fractions, however, do not match measurements of H, C, K and Fe on Ceres4. A complicating factor in assessing Ceres’s unique surface composition is the secular accretion of asteroids typical of chondritic compositions. Here we show that Ceres’s… Expand
Organic Matter and Associated Minerals on the Dwarf Planet Ceres
Ceres is the largest object in the main belt and it is also the most water-rich body in the inner solar system besides the Earth. The discoveries made by the Dawn Mission revealed that theExpand
Characterization of NH4-montmorillonite under conditions relevant to Ceres
Abstract Research interest in NH4-smectites in planetology is increasing after the discovery of their high abundance on the surface of Ceres. This dwarf planet is considered a relic ocean world,Expand
An endogenic origin of cerean organics
Abstract Localized deposits of aliphatic organic-rich material have been found on the surface of dwarf planet Ceres, and based on mineralogical context, it has been suggested that these organicsExpand
A carbonaceous chondrite and cometary origin for icy moons of Jupiter and Saturn
Abstract The inner structure of icy moons comprises ices, liquid water, a silicate rocky core and sometimes an inner metallic core depending on thermal evolution and differentiation. Mineralogy andExpand
Slurry extrusion on Ceres from a convective mud-bearing mantle
Ceres is a 940-km-diameter dwarf planet that is predominantly composed of silicates and water ice. In Ceres’ partially differentiated interior, extrusive processes have led to the emplacement on itsExpand
Experimental clues for detecting biosignatures on Mars
Forthcoming exploration of Mars aims at identifying fossil biosignatures within ancient clay-rich formations. The subsurface of Mars has mostly acted as a giant freezer for the last 4 Gyr, therebyExpand
“Water” abundance at the surface of C-complex main-belt asteroids
Abstract Recently published space-based observations of main-belt asteroids with the AKARI telescope provide a full description of the 3 μm band, related to the presence of OH bearing minerals. Here,Expand
The composition and structure of Ceres' interior
Abstract Results of Ceres' exploration with the Dawn spacecraft are modeled and discussed in terms of rock/organic/elemental composition, density and porosity in the interior, and formation,Expand
Widespread carbon-bearing materials on near-Earth asteroid (101955) Bennu
The OSIRIS-REx results constrain Bennu's evolution and provide context for the sample collected in October 2020, as well as finding evidence for organic and carbonate materials that are widely distributed across the surface but are most concentrated on individual boulders. Expand
Ceres’ partial differentiation: undifferentiated crust mixing with a water-rich mantle
Aims. We model thermal evolution and water-rock differentiation of small ice-rock objects that accreted at different heliocentric distances, while also considering migration into the asteroid beltExpand


Carbonaceous chondrites as analogs for the composition and alteration of Ceres
The mineralogy and geochemistry of Ceres, as constrained by Dawn's instruments, are broadly consistent with a carbonaceous chondrite (CM/CI) bulk composition. Differences explainable by Ceres’s moreExpand
Bright carbonate deposits as evidence of aqueous alteration on (1) Ceres
Spectra of these bright areas in the Occator crater on Ceres are consistent with a large amount of sodium carbonate, constituting the most concentrated known extraterrestrial occurrence of carbonate on kilometre-wide scales in the Solar System. Expand
Modal mineralogy of CI and CI-like chondrites by X-ray diffraction
The CI chondrites are some of the most hydrated meteorites available to study, making them ideal samples with which to investigate aqueous processes in the early Solar System. Here, we have usedExpand
Elemental composition and mineralogy of Vesta and Ceres: Distribution and origins of hydrogen-bearing species
Abstract Combined analyses of the surface elemental composition and mineralogy of Vesta and Ceres provide insights into their interior evolution, crustal formation, and regolith processes.Expand
Nature and degree of aqueous alteration in CM and CI carbonaceous chondrites
We investigated the petrologic, geochemical, and spectral parameters that relate to the type and degree of aqueous alteration in nine CM chondrites and one CI (Ivuna) carbonaceous chondrite. OurExpand
Ammoniated phyllosilicates with a likely outer Solar System origin on (1) Ceres
Measurements of Ceres indicate widespread ammoniated phyllosilicates across the surface, but no detectable water ice, which suggests that material from the outer Solar System was incorporated into Ceres, either during its formation at great heliocentric distance or by incorporation of material transported into the main asteroid belt.

Distribution of phyllosilicates on the surface of Ceres
The widespread presence of these two types of minerals is a strong indication of a global and extensive aqueous alteration—i.e., the presence of water at some point in Ceres’ geological history. Expand
Classification of hydrous meteorites (CR, CM and C2 ungrouped) by phyllosilicate fraction: PSD-XRD modal mineralogy and planetesimal environments
The relative differences in the degree of hydration should be reflected in any classification scheme for aqueously altered meteorites. Here we report the bulk mineralogies and degree of hydration inExpand
The origin of eucrites, diogenites, and olivine diogenites: Magma ocean crystallization and shallow magma chamber processes on Vesta
The asteroid 4 Vesta is one of the very few heavenly bodies to have been linked to samples on Earth: the howardite-eucrite-diogenite (HED) meteorite suite. This large and diverse suite of meteoritesExpand
Coupled organic synthesis and mineral alteration on meteorite parent bodies
The hypothesis that the soluble fraction of the organic compounds present in carbonaceous chondrite meteorites was formed during aqueous alteration of the parent body was tested with masstransfer,Expand
