A very slow impact that allow Tethys to rotate under the material as it was slowly falling. Obviously, with that scenario, an exogenous source.

As for the color, right now I've got nothing better than sharpie...

Looks like tectonic cracking of the surface, which is somehow exposing material of different composition than the surficial layer. Maybe there was an ancient impact basin here and the underlying crust still "remembers" the cracking, which serves as a conduit for material slowly being moved to the surface?
