Figure 7: The kinematic flow of material that forms the peak ring.

From: Peak-ring structure and kinematics from a multi-disciplinary study of the Schrödinger impact basin

Figure 7

The flow of material is tracked for the (a) 20 km-thick crust scenario and (b) 40 km-thick crust scenario. The black dot tracks the tracer that ends up closest to the middle of the peak ring; the point at the other end of the line tracks the tracer that starts 2 km below the black dot. Hence, the length and orientation of the line shows the separation and orientation of material that was originally 2 km apart and vertically aligned and becomes stretched and rotated to horizontal through excavation, collapse and uplift.
