Very good teacher, thanks for taking the time in this busy time.

Brilliant video! Thank you so much! This really helps!

Superb! Thank you.

Nice smooth and informative video.......

learnt a lot from this!

So helpful thank you!

Awesome teaching... from a once-clueless now slightly clued-up rookie rockist! 🤣

Very nice

I have found some pieces of that rocks.also dug up a big rock .

From what i understand, pegmatitic rocks do not form very slowly but actually extremely quickly. On the scale of days to years. This due in part to the melt being rich in flux element (H, B, F, O) before it solidifies. Really enjoying the series, Thank you!

Hi J Dean, Thanks for your support. I teach at the Colorado School of Mines. My general interest is Earth Science, and my specialty area is paleoclimatology (ancient climates). Happy New Year to you! CVS

J Dean Geobotany, specifically the study of plants preserved in the Earth's crust, is not my speciality. Both Stephen J Gould and Richard Dawkins have several excellent books on general evolution. Kirk Johnson of the Smithsonian is a paleobotanist and has some interesting content on-line. As for mineral deposits, we have an excellent school for that subject. My colleagues could tell you so much more. Thanks for your feedback. I do this in my spare time and never know if it is having an effect until people like you let me know. Thanks.

J Dean There is a book called "Non Ferrous Metal Ores" which deals with plants as well. This website is a quick overview: technology.infomine.com/articles/1/1650/indicator-plants.geobotany/indicator.plants.aspx

Funny as hell!

1:48 can someone tell me what is going on with this rock? There’s an old timers mine with this as the outcrop like this near home. I would like to know what it was mined back in the day.

I'm an American so I have no understanding of metric sizes. Just as Eurosnobs don't comprehend American measurements....

It's not hard to learn and apply conversions. The internet is kind of handy with converting to superior international units. You are really going to struggle doing any efficient science without metric.
