the great age of everything on the surface of Mars?

Not that you are wrong, you may well be right. But what is the basis for your assertion?

For example, in the case of this apparent meteorite, it seems to me that the nearest analog on earth to this finding is the meteorites found on the ice surface in Antarctica. While the objects themselves may be of great age, their presence on the Antarctic surface is not particularly ancient. In fact, their presence is quite recent in geologic terms.

Now, could a similar scenario occur on Mars? Could this meteorite have fallen to the Martian surface relatively recently, and if so, might it tell us something about conditions at Meridiani in the relatively recent past?

Asserting enormous age is all well and good, but turn it inside out. Maybe this thing fell relatively recently. How might that scenario play out?
