I was looking at some of my latest material from Pipe Line Canyon and started noticing the color changes and banding just below cooling surface crusts.
Notice the rock above with the word "Surface" written on it in white.
Below is a close up so you can see the surface texture and some of the banding and "moss" patterns below it.
The followings are all photos of another rock, but look how the various "surface crusts" are placed.
The bright white triangular spots you see are reflections from crystal faces.
Next you can see three surfaces meeting at the "knob".
And the grand finale, a surface impacted into another.
It looks to me like this material was violently laid down, started cooling, then was shattered and tumbled, then cooled again, then re-shattered. No wonder it is so mixed up.
