Within the dome the following geological units can be discerned:
According to field findings geological units in the region as follows:
About 35 million years ago, tectonic forces, that are still active today, began to push these geological units northwards.
Colors are used to represent different geological units.
The model could be represented by triangulated objects each corresponding to one of the geological units present.
The former are described in detail below; the larger geological units are discussed elsewhere under bars.
The crater and the area immediately adjacent to it are divided in a number of geological units.
All its geological units contain much less small impact craters than the surrounding crater plains.
Like Slag Hill, it is composed of two geological units.
Like Pali Dome, it is composed of two geological units.
