Validity of impact-driven central uplift forming domes

Ascertain whether impact modification mechanics in icy lithospheres can produce central uplift of a rheologically weak layer sufficient to form domes within central pits on Ganymede and Callisto, and determine the conditions under which such impact dynamics would operate.

Background

A proposed mechanism for dome formation is central uplift during the impact modification stage, which requires a globally weak layer to explain dome morphology. The authors highlight that it remains unclear whether the impact mechanics can actually produce domes in this manner. Establishing the feasibility and parameter space of central uplift in icy bodies is critical for assessing this hypothesis.
