Why is Feldspar always mixed with other stuff in a granite composition?
Why can't I find just plain FELDSPAR??
I especially like the pink kind -- and I may or may not be talking about rocks.

Engineer. Enough said.
Who says I'm doing nothing with my knowledge. What if some lurker realizes he likes geology because of this thread? Or what if I'm getting my PhD?!

And if someone wished to...acquire some of these rocks...what tools would that person need to bring?
Do you have any gneiss big rocks for sale?

Why is some argillite so unstable in drilling environments?

The banding is fairly thick, not in thin layers like I've seen in gneissic banding. I've seen bands that were from 1 to maybe 5-6 inches thick.
I'm not sure the Pikes Peak batholith goes that far south but maybe it does. Or it could be a different but similar batholith.
PP granite is approx. 1 billion years old. Not that that has anything to do with anything, I just find that fact interesting.
Yes. The banding at Royal Gorge is very thick, almost and practically is migmatite (one step up from gneiss).
The granite is from the batholith, the gneiss is older and deeper than that and was exposed due to the carving into the Earth by the Arkansas River from the latest uplift of the Rockies.
I will look in my field book real quick to see what I have the date for for the gneiss and granite.

How does the transition from Metamorphic Ultramafic into Serpentinite work?

What's the typical composition of a moon rock and how hard would it be to fake one?
The Moon was made from the magma of Earth after it was jettisoned out due to a collision with a very large body. I think moon rocks are basalt sprinkled with olivine (perhaps peridotite) mafic to ultramafic igneous rocks.

Thank you, I'm sorry I overreacted.

I'll hang up and listen.
Without a doubt, river-rounded flat pebbles (like slate). Go to Arkansas for this!

A shell is not a rock. A rock can be composed of shells.

It can be just feldspar if you break off a piece from a huge feldspar crystal
The real reason is this:
Potassium feldspar is what makes granite all pink because it's the main mineral in granite.

so a shale formation, is it actual rock?
