Very helpful, on a surprisingly difficult topic to teach clearly! I know, because I’ve watched a lot of videos, without feeling like I’ve learned much I can use. Thank you!
What a flashback!!! When I was very young, we felt as though we had struck gold if we found a piece of slate. It was the best to play hopscotch with!! Love the shiny pieces. Thanks Glen.
Even gneiss in crystal form like a granite will have had pressure flattening the crystal. So granite crystal like quarts, feldspar, hornbeam will be uniform in all directions, nut gneiss will be shorted where pressure is applied.

Glad it was helpful!
In first year geology and I can’t describe how much you helped! Great depth and explanations really appreciate the video
Glad it helped! Good luck with your degree.

Did you find the slate on peoples rooves, thanks Ricki.
Thanks Glen, I'm interested in Geology.👍
It is fascinating. Thanks mate
Thank you for your detail explanation. I just found a rock can contain granite and quartz together.
Granite is a rock that has the mineral quartze. But in some cases a granite zenolith can be in another rock with quartz.
How would you tell the difference between the last piece of gneiss without banding and granite?
