Cross-Section of a Complex Crater
ESP_058057_1465  Science Theme: Geologic Contacts/Stratigraphy
This image shows a cross-section of a complex crater in Terra Cimmeria.

Starting in the center, we see a series of peaks with exposed bedrock. These peaks formed during the impact event when material that was originally several kilometers below the surface was uplifted and exposed. The impact also melted the rocks. This eventually cooled, forming the pitted materials that coat the crater floor around the uplift.

The rim of the crater was unstable, and collapsed inwards to form terraces, and we see additional pitted materials between the terraces and the rim. Just outside the crater we can see dark-toned material that was excavated and thrown out after the impact.
