Hard to say, but they also say that this is also an area were very little meteor's have impacted. They say they think it is younger than the rest of
the planet.
You have to remember that alot of stuff is preserved in places like the moons where there is no atmosphere. That's why the big space race is going
on right now to get there and mine Helium-3. Also this stuff is very thick kilometers I think. So if this is something of signifigance it would be
very good place for the next mission to mars to start analyzing the mineral composition.
