Hey good morning. Isn't this incredible? I am leaning very hard now on water and a concretionary source for this to occur. I can't think of any metamorphic state that would yield spheres unless it was a weird type of retrograde metamorphism affecting certain phenocrysts.

Yep, seems water had to have been involved.

So what do you think of the closeups of the outcrop rocks? That's some REALLY fine foliation.

Now that the pics are closer they look like they MIGHT be "crumbly"...I'm curious if they're really hard or if they'll crumble when the arm is put on them.

You took the words right out of my mouth!

My dog has metamophicized many objects through excretionary processes yielding many spheres which can be found throughout the backyard. I don't think it was phenocrysts though, just kibble. Evidence of Martian canines methinks. ;-P

You are not thinking of the gravity that's all. It's different, it will yield to different shapes. I think.
