Shock veins. Shallow faults caused by hypervelocity impact.
No need to post an example, as they are all around nearly every crater on the moon.
Also, in the SW portion of the scene, the parallel wall structures are part of the impact. They are outer crater waves frozen in time. An impact like
this briefly turns the surface into behaving like a liquid, like a drop of water in a pool. The waves of material as they travel outward freeze in
time as the materials instantly re-solidify.
There are 2 main rings in this crater, and a shallow wall structure is what would have been a third, but never really formed before it ran out of
This is a great example of a low angle impact.
