Oh, there is definitely a story out there in terms of cratering rates and how the current erosion rates work on erasing cratering remnants. And I'm sure that somewhere someone is working on it.
However, while we are at a point where we can do *comparative* dating of various geological strata, we just are not and cannot be in a position to do *absolute* dating until and unless we have samples in hand (or we figure out how to do rock dating remotely, on in-situ landers). In fact, for the larger-scale landforms, we already have a comparative dating system (Noachian, Amazonian, etc.). But the actual date ranges in which these land-forming events took place on Mars is still nothing more than energetic arm-waving, at this point. And, again, this will continue to be the case until we can pin down absolute ages in some fashion. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
