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!
Enjoy bible camp ! ..no big samples indicate slow cooling ,one degree per 1000 years , in washington st. 3 mile thick layers of lava , they do cool slow ....
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.
5:40 the most famous rock, the same rock that trapped the chilean miners, a so-called 'megablock' of diorite 45 stories tall weighing twice as much as the empire state building
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
Great! any recommended reading on Geobotany and mineral deposits? or anything to do with the subject........i'VE got to THANK YOU as much as i can..... its put moreandmore into perspective! jd
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.
im a layman...specfically which plants of western N.America grow around mineral deposits.....ive heard of a few....its either a small subject or very well hidden? Cheers, jd
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

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.
Very good teacher, thanks for taking the time in this busy time.
Brilliant video! Thank you so much! This really helps!
Awesome teaching... from a once-clueless now slightly clued-up rookie rockist! 🤣

If an object falling from sky is covered with lava, then it is a terrestrial rock?

It’s a pegmatitic granite in my mother’s backyard. Not sure where she got it.
So helpful thank you!
Superb! Thank you.
Nice smooth and informative video.......
I do have many off metoroite you like to buy them so how can I contact you sir...
How do I communicate with you to see the rocks that I have with me to see their kind
?
Thank you these videos rock 🤣 I want to study geology

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