Exposing Colorful Deep Bedrock
Exposing Colorful Deep Bedrock
ESP_062877_1690  Science Theme: Composition and Photometry
Large impacts produce uplifted central structures, either peaks, or pits, or an uplifted peak with a central pit. This crater south of Aurorae Chaos has a central pit exposing bedrock units with diverse colors, indicating diverse rock compositions.

This crater includes clay-rich minerals identified by the CRISM instrument on MRO. See this enhanced-color cutout over the eastern half of the central pit.
