This video is far underrated and appreciated. Should be more views IMHO. I found this very helpful for helping categorize different igneous rocks. Thank you for posting

Studying for my geology exam and this helped me understand so much more then when I learned it in my class thank you

These videos are incredibly helpful! Thank you for making these!

That was an excellent presentation and the camera work was good about getting in close at the right moment!

The chart is in the NAGT AGI Physical Geology lab manual. Check out one on Amazon or other online bookseller.

Despite how bad the cameraman recorded this video, the explanation is really helpful. Thank you !

Best video I have seen on this subject. Really helpful. Thanks!

Where can i purchase that wonderful chart? I am a self taught amateur and I love to travel and learn of the geology... That Chart makes so much sense to me. A chart like that will be a good exercise in training me how to read igneous rocks.

Thanks a lot for your presentation. I love Geology! and I'm a Geologist.

awesome greetings from Panama

very nice lecture, thanks for your clarification

very interesting. thanks. nice to have a seat in the classroom again. :D

How long does it take for a reptile to fossilize or become quarts ?

Great presentation, thank you! Funny how American English and British English appears to have different pronunciations for certain minerals : )

where can I get that chart?

hello Profesor! one question more...ignimbrite rock is also a toba? thanks!

Contratulations for all the explanations! is there any other way to get this chart apart from amazon. I live in southamerica and its no cheap to get it. thanks!

Awesome

what is the name of the rock that is round and smooth?

Where can I get that classification chart...

Great video. Love the chart. I guess it is copy writed?

Just a note on Labradorite: The geological type area is Labrador, which is part of the Canadian province called Newfoundland and Labrador. It is pronounced: Lab-rah-door-ite (as in the dog breed Labrador Retriever) and not Lab-rad-er-ite. Very helpful and informative video, though.

I have never heard use the porphyritic aphanitic category. Minerals are never going to be the same size in a granite. That's not a good enough reason to call it porphyritic.

in conclusion, tuff can be tough

Please madam share link if this diagram

I know of a missing link in the education of geologists. They tell us that our planet Earth has the most to fear from an asteroid impact or volcano eruptions. But when we look at the many horizontal layers that we find everywhere on our planet, we clearly see the effect of a repeating cataclysm. These disasters are mentioned in ancient books like the Mahabharata from India and the Popol Vuh from the Mayans and others. They tell us about a cycle of seven disasters that separate the eras from the world. Certainly, regularly recurring global disasters cannot be caused by asteroid impacts or volcanic eruptions. The only possible cause is another celestial body, a planet, orbiting our sun in an eccentric orbit. Then it is close to the sun for a short period and after the crossing at a very high speed it disappears into the universe for a long time. Planet 9 exists, but it seems invisible. These disasters cause a huge tidal wave of seawater that washes over land "above the highest mountains." At the end it covers the earth with a layer of mud, a mixture of sand, clay, lime, fossils of marine and terrestrial animals and small and larger meteorites. Forests that existed are flattened and because of the pressure from the layers on top the wood is changed into coal. These disasters also create a cycle of civilizations. To learn much more about the recurring flood cycle, the re-creation of civilizations and its chronology and ancient high technology, read the e-book: "Planet 9 = Nibiru". It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9

all i can say is MERICA

boring
