Granite Gneiss, how to identify granite gneiss.

Gneiss to know!

Excellent, great teacher. Answered my questions and got right to it!

Why do the stripes form? Different melting points?

Looking at the title, I was hoping you would explain how to distinguish granite gneiss from non granite gneiss..... still, a very good explanation.

How to differenciate a granite gneiss from a granite with magmatic foliation? Good video.

Biotite? How about hornblende?

Oh my god

Sir I asking same question?the granite gneiss stone is ah magnetic or not?

Granitic Gneiss.

Yeah I'll make my way over Georgia in a heartbeat... just kidding I'm from England and I just happened to find this haha. Now I know more about metamorphic, that huge piece you had helped my visualize the process and transformation of the original granite.

I just take a rock, throw it up into the air and let it land on my head. If it hurts I know that rock is mean. And if it's mean it can't be gneiss. So far I haven't found any gneiss rocks.
Now I find out I was using the wrong method to identify gneiss rocks?
Well at least I found out how to identify mean rocks. Does anyone have an aspirin. I have a really bad head ache.

I would never take gneiss for granite..

Beautiful! Thank you so much! I think what I've got in front of me is slate, but I've only just started my journey.

Is there any way to figure out which edge of a rock was at the top or bottom when it was formed?

Is it ortho or para sir?
