It looks more like a massive ejecta sheet to me, and we do see those commonly on our own Moon. They are most often seen, on the Moon, as ejecta from large basin impacts. As a comparison, take a look at the Fra Mauro formation on the Moon's near side.
In fact, this resembles that kind of structure quite a bit. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
