Huh. I've never really bothered to really look at Mars photos before. Now I wish I had, this is fascinating. One of the reasons I love ATS, I'm
exposed to so many different topics every day that normally I would never hear about/bother with. Thanks for the thread.
I've become kind of a rock-nerd over the past year.
Anyways, what I see in the pictures is this:
1A and 1B, I honestly don't see anything that stands out.
2 is one heck of an interesting looking stone. Would like to have it in my garden. Looks kind of like a lemur, heh.
The rocks pointed out by NASA in the photo are *incredibly* interesting to me.
A looks like metamorphic rock, like it was subjected to very high pressures while still in a plastic, but not molten, state. Like maybe from a
subduction zone, which would fit with the preponderance of sedimentary deposits in the photo.
B is fascinating. I wonder if that, what looks like pitting, is indicative of bubbles throughout the rock, or if the pitting is a surface-only
feature. And if it is only on the surface, then what caused it?
C looks to me like what I imagine a clump of planetary mantle rock would look like if you scooped it out of the mantle and kinda just plopped it down
on a baking sheet to let it harden. Cool.
Or maybe volcanic ejecta.
These Mars pictures are so cool!
