At least we are somewhat agreed on the idea that the surface must have not been completely solid and that, somehow, this object ended up in the
position it is in.
As we see in the pics of the other craters, the central 'tower' protruding from most of them does tend to suggest some form of liquid/molten
rock/substance that solidified before it had chance to fall in on itself.
To me, that alone is quite a feat. All those tons of material suddenly freezing in position. Incredible forces at work there.
This object could very well originate from Mercury and, as we tend to agree, has been semi submerged into the surface. I suggested earlier that it
could have been airborne at one point in order for it to have spun itself into this circular formation.
Or as you suggest has been lifted from the floor. This makes me wonder what could have created it. It could have been the remains of a first strike,
the material solidified as a disc, then a second strike, or even earthquake, could have lifted it into position.
Let's hope that another pass by Messenger will reveal more images of this area. I'm sure NASA would love to have more images of this so they can
upgrade their description from 'a dark patch' to something a bit more scientific like 'a dark round thing'...
