Geologic mapping of the Ac-2 Coniraya quadrangle of Ceres from NASA's Dawn mission: Implications for a heterogeneously composed crust

•We mapped the Ac-2 Coniraya Quadrangle of Ceres at a scale of 1:500,000.•We derived CSFD measurements for all major surface units and obtained theirAMAs.•The youngest features are the fresh craters like Oxo (∼4 Ma) or FC IV (∼12 Ma), while the oldest unit is the cratered terrain (3.1 Ga to 3.5 Ga).•We identified smooth impact melt-like deposits with pits in and around Ikapati crater.•Possible ice in the crust is heterogeneously distributed, as lobate flows, bright spots, and pits are only found at certain locations such as Ikapati and Oxo.
