Marcia — (archived)

I agree with Mark on all his points.

Lately, whenever Olivine is mentioned or discored, I feel the same way:

"Why can't the Olivine come from volcanic eruptions post dating wet Mars? There is strong evidence Martian volcanism was active far past the supposed wet period."

We've seen features on the surface of Mars that resemble those of Earth (esp. what seems to be ancient rivers and deltas). We're finding new things on Earth that we don't plainly see on Earth's surface.

That new discovered canyon on Earth reminds me of one on Mars... it was similar to one that is in an image that I posted recently here, but I can't find it now (I can't check prev. pages). I mentioned that the coastline or cliff lines reminded me of the coastal lines of Florida up to Cape Hatteras. There seems to be a similar 'canyon' feature next to that Martian coastline. The surrounding areas of several of those 'coastline' features seem be devoid of impact craters... just lucky areas?

Who knows, maybe someday we'll find something like this when some robotic driller or astronaut geologist performs a deep core sample and who knows what else may be waiting.
