Embedded Crater at Mawrth: possible crater within stratigraphy in the wall of a younger crater

Latitude/longitude:23°26'55"N, 18°52'20"W

Rationale:Provides insights into the origin(s) of bedrock, including the influences of impacts on that bedrock.

Morphology and Mineralogy: Consists of a dish-shaped form within the wall of the crater, overlain by flat units as well as deformed units. Deformation of layers at the margins suggest it is an impact crater. Mineralogy unknown to me.

What will the rover specifically do?Study composition of associated bedrock, characterize textural and mineral changes with variable proximity to the embedded crater to evaluate timing of mineral deposition/formation, and refine models for bedrock formation.

Edge of a ~17 km diameter crater with deformed walls at the top and lower half of this image. A small area with approximately horizontal layering contains an embedded dish-shaped structure, interpreted as a small impact crater. White box outlines approximate view in the following slide.
