Dawn spacecraft images of Ceres indicate a vivid topography, large and deep impact craters without fluidized outflows. These features are consistent with a rocky and undifferentiated internal structure without water mantle. The undifferentiated structure of Ceres was predicted in 2009. That paper demonstrated that Ceres could be a porous rocky body with mineral grain density similar to that of carbonaceous chondrites. Dawn data (2019 analysis) are consistent with compressed undifferentiated Ceres.
Carbonates detected in Occator crater suggest a rapid isochemical emplacement by post-impact plumes. Salts could have deposited in ice grains from plumes and accumulated at the boiling depth. Other bright materials are excavated plume and subsurface salt deposits.
