RABC of nearby rock and soil:

with links to views up and down from this image and links to overlap of the images.
These are 2X views without white balance.
Very curious. the images had to be translation registered to produce the color image. Was the arm moving when the images were taken?
OK, what do the rock guys see?
Not basalt?
What are the white edges?
What are the "blue"(er) surfaces?
What are the subtle pattterns in the soil?
Looks like some of the rocks have a patina that on some is chipped.
My favorite surface pattern is here -- lower left.
