The sample visible on the left at 1:53 when striations are being discussed actually shows exsolution lamellae (intergrowths of two feldspars together), not striations due to twinning.

I'm a rock climber on Long Island NY. We only have glacial deposits. Your videos are helping me understand what these boulders are made up of. Thank you

I really like your series of videos! It's a great resource. Geology needs some good images and videos, since there are a lot of rocks and visualizing them is always helpful.

Tengo un mineral como él que muestra al minuto 05:13.. alguien me diga que es? Y si tiene algún valor? por favor!

[alancarlyon]

I come across a lot of quartz when walking in the hills and mountains - They are awesome - yet no value, unless one finds gold or silver and creates/make a quartz ring! Great blog - many thanks!
