So, updated version of the Sol 2140 color pan of Concepcion. We can now see it entierely :


(I prefer to link to my page because the direct link to the full version will lead to load a 4.4 Mo pic).

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

The shapes on this (left) rock look like an ancien map of the (Mars) world, don't you think?

It's not such a fresh crater after-all, the protective coating is wearing off the debris.

A mechanically weak layered deposit, originally formed in a fracture, is falling apart now it's exposed to the surface environment. Age can't be determined from the appearance of the rock if we don't know its strength.

It looks as if a congregation of berries became cemented into the rind, almost like a clast? The upper portion looks as if large crystals formed, perhaps hinting at how long this vein formed under solution?

Could this be the "impact melt" the team referred to ?

They mentioned a dark crust that was potentially impact melt. I'm sure this is what they were referring to - the only other rock crusts around look very similar to this.

Do these closeups provide any hints about whether this is a filled fracture or impact melt? Obviously the IDD work will be important...

The multi-layered appearance would argue strongly against impact melt, but more seriously still, this is on a bit of Meridiani sandstone, not an exotic rock. Evaporitic deposits in a vein - an old fracture - make far more sense, especially since we've been seeing these vein-filling materials ever since Eagle crater.
