Fig. 5: Cross section through Occator crater, including schematic subsurface structure.

From: The varied sources of faculae-forming brines in Ceres’ Occator crater emplaced via hydrothermal brine effusion

Fig. 5

The colors shown in this figure correspond to the geologic units (as defined in Fig. 1a) and key features are labeled. This figure does not illustrate a particular time-step in Occator’s evolution. Impact-derived fractures form conduits to source the faculae-forming brines, and the impact-induced melt chamber thermally connects to the deep brine reservoir. The sizes and depths of the impact-induced melt chamber and deep brine reservoir are schematic, and are based on refs. 9, 30, 32, 49. We do not show the warping of the lobate material by the formation of the central pit in the cross section, because it is out of the plane, which was chosen to show the key features in the crater. The profile is taken from the LAMO DTM59, and the line of the profile is shown in the inset image.
