Do you suppose that we will be collecting agates on mars in our life time? Don't know if it's realistic or not but it's fun to think about.

Does Mars have agates? Are you sure? Wonder if they are banded or have dendrites or plumes? Stefan, when you go to look for your house, bring some back with you for us ok? I'll loan you my bucket. *smile*

Well the possibility of agate on Mars wil depend on how mych Silicia (Silicon?) and Oxygen. Oxygen is also needed to for the water that carries the SiO3 into the formations. I wonder where I can find out about Silica on Mars?

Thats right, I forgot that water is part of the agate making process. Didn't the scientists figure that there is or was water, it's just not on the surface anymore?

I would guess Mars to be iron rich, hence the red. But if there were water and silica on Mars so many (thousands? millions?) of years ago, wouldn't that be neat if the rovers or future astronauts found some crazy agates, etc. in the canyons or under the soil?
