I wonder if those could be the holes where relatively (to the blueberrys) large sized concretions once were?

Could these be Blueberries in some of the holes in these rocks? I don't think i've seen any rocks that looked like that before. blink.gif

It's a dead ringer for Utopia Planitia. I think the holes are vesicles.

Now the question is: did the holes form around the material that is filling them in, or were the holes there first, later to be filled by a secondary deposit? If it is the latter, then it would suggest that water moved through the rock after it was deposited.
Will we be able to answer that question just by looking at the images? I don't think so.
