Granites are my favourite igneous rock, what's yours? Check out my shirts below, more will be added soon!

I live on the Eastern edge of Albuquerque where it butts up against Sandia Crest, 10, 678' of pink granite capped with limestone. The decomposing granite makes a very pleasant crunchy sound under your hiking boot. I've always been fascinated with rocks but don't have the education so I look forward to watching more of your videos to learn what I can.

Very clear and easy to understand.
I am trying to teach myself some amateur geology. It helps with my hobby of gold prospecting. Your videos are easy to absorb. 👍👍

The 4 types of granite are presumably accepted worldwide.
Thanks for the concise and clear narrative.

Great video Geology Johnson, excellent overview of some topics which can often be painfully confusing

this was amazing! I have been looking for more academic videos. THANK YOU

Greetings again from the other side of the Atlantic, in Maryland. You recommended that I check out this granite video because I had posted a granite pegmatite that glows green under UV. Thank you again. By the way, the Shakespeare of German literature, as it were, was Johann W. Goethe. He was an avid amateur geologist. Anyway, he wrote an essay in 1784 called On Granite (Über den Granit). Interesting. He thought it to be the oldest rock and that it must go down to the deepest depths of the earth. He wrote other things about geology, too. Back then it was still possible to learn about everything that was known about geology. He points out that the French and Italian geologists were misidentifing granite. His own definition seems to be still correct, but after seeing your video, I realize now he had no way to distinguish the specific types you outlined. His def, as I recall, was just the three minerals: quartz+feldspar+mica. Which isnt bad for 1784!

Thank you! I learned a lot. I live near Yellowstone. Planning to go have a look.

Found you after doing some research. I live in Townsville, Australia. There is a massive pink granite monolith - that I thought was a batholith, but I was wrong - in the middle of the city! It's named Castle Hill. We like it :)

That was a really interesting bit of in-depth explanation of what is granite, I wish you hadn't stopped when you did. I'm sure you could have told us a lot more. Well I guess I'll just have to subscribe and catch more of what you know about geology.

Great Video Thank you, At the time that I am exploring why our ancestors have chosen granite to do rock Art (paintings and rock engravings). I have seen paintings on white Marble as well but granite is the most favorable rocks based on findings and are used as painting attractors Archaeologically. Proposing a joint study

Excellent video, i grabbed my pen and pad. I ve learned in 11:29 video a solid vocabulary and sequence of events that a true geologist would relate,
Very well explained and straight to the granite mystery Granite story, that i never knew about. Thanks

[leduke]

Decided to learn a bit about rocks. This was the second video, and 30 seconds in, it was like and subscribe. Nothing is better than get to know stuff through a geologist nerd. You fit the bill, there, and I know you take it as a complement. :D The general information combined with the exposure of your in depth knowledge is making it great to watch. I'd like even more example footage while explaining, in the lines of what you did, just more.

That was very interesting & informative thank you 😊

Good video big fella I watch a lot of Jeff Williams geology videos mostly for gold prospecting but it’s always nice to listen to straight geology

[jorrvaskrr]

Most excellent! And love the labret :)

[malachi]

Im a sculptor and this was amazing thanks dude!

[lisadee]

Thank you, that was very informative.

there’s a skyscraper in Houston clad with grey granite blocks from top to bottom. The tallest sky scraper in Houston. Very cool. I like red granite too, from a purely aesthetic perspective. But the grey granite is beautiful too and as a building material seems to be less utilized than your standard classic red granite stuff

[misteralienman]

Hi Geology Johnson. Thanks for the video. this was very informative. Do you by any chance have any videos about gases? Is this a part of Geology or does this delve into the realm of maybe meteorology? Just wanted to know more about neon or other elements that make up atmospheres.
