I found this study of the Micas and occurence rocks very interesting and enjoyable . Learning something new every day. Thanks.
Every night I hop into bed and happily look forward to my geology lesson. Love all your sample choices. The pointing out of the minerals, and the repetition help to cement in the lessons.
Thanks, Shawn! These rock and mineral videos are well done!
Loving these videos. Finally understanding what the minerals look like in a hand sample. Looking forward to more. Thanks for the series.
Thank you for another great video.
I am so thankful to watch your class by accident，it is amazing and helpful，many appreciation.I am freshman in professional in mica insulation materials and services in China，so i study some theoretical knowledge from your video over and over again and I have noticed the address you sent to the guy below comment，thank you！
I just found this series and I want to say how much I appreciate your passion for teaching. I hope your students appreciate you half as much as I do for your clear examples, the fact you uploaded the sheets to google drive for us and just how you're sharing your knowledge with us. Thank you. I look forward to watching through the others in the days to come.
Once again, another great video. I like the straightforward presentation, iPhone and info printed on paper. No fancy titles, transitions, or other hyperbole. I feel like I’m in the classroom with you and totally nerding out. And please keep up the great work. It’s very much appreciated and meaningful. Your passion for your subject is evident.
Excited every time I see a new video in this series. Forwarding to my sons in Idaho and our friend in BC.
I enjoyed your remark about micas thriving in a certain environment.
Nerds like you help nerd like me, been watching a bunch of your stuff thx mate
Great one Shawn. I might just be developing the "eye" to see different minerals in the same sample. Thank you again for an entertaining lesson.
Thank you for doing this series!
I have always loved stones and rocks but knew nothing about them, now I’m learning about quartz, what metamorphic means and what those shiny things are in rocks that fascinated me for years. I live on the farthest northeast coast of Scotland surrounded with fascinating geology. My beach combing days will never be the same again. Thank you Shawn.
Great comment. So glad to hear this will help your adventures in Scotland. I visited there in 2016 and it was an amazing trip.
Really enjoying these. Thanking you for taking the time and putting in the effort to make them. That's true for all your videos. Much appreciated.
Very thorough. I need my thinking hat and full attention for this series!
Great presentation again thanks love your work
Thank you kindly. I appreciate your support.
Great series.
0:40 definitely interested in the chemistry of rocks!
Thank you Shawn. I'm plowing through the minerals and rocks videos and enjoying them all. I think once I get through your entire library, I will purposely return to these foundational videos to better "cement" my knowledge base. Repetition, for me, is critical. Your conversational approach is marvelous even when using notes.
Yeah, it seems like you are on a video binge. Glad you are enjoying them all and that my style suits you.
Great video! Makes it more obvious to me the particular shine of the micas. Can't wait for the next ones!
One fascinating thing which jumps out at me is that micas, the second most common mineral in the earth's crust, has most of the elements by number of moles required for mammalian life: K, Na, Ca, Mg, Fe, O, H. Note also that Si is in the same column of the periodic table as Carbon. Here is list:
Hydrogen (H)
Oxygen (O)
Carbon (C)
Nitrogen (N)
Phosphorus (P)
Sulfur (S)
Potassium (K)
Sodium (Na)
Chlorine (Cl)
Magnesium (Mg)
Calcium (Ca)
Iron (Fe)
Zinc (Zn)
Copper (Cu)
Manganese (Mn)
Iodine (I)
Selenium (Se)
Molybdenum (Mo)
Boron (B)
Fluorine (F)
In some science fiction stories, planets are populated by silicon based organisms. We could call them micas! Thank you for stirring my imagination.
I've always been fascinated by mica. It's all to do with the shiny. I didn't realize until today how many types of rocks can contain it.
Very helpful..Rock snooping Coromandel Peninsula nz today.
After watching the video (thanks Shawn!) I decided to check out the crystal structure of a couple different micas. Whoa! A bit like a graphite maybe, but far more complicated in structure. Chemistry be amazing sometimes.
Great videos, thank you
Thanks! Looking forward to the future videos.
Excellent video on the lovely micas!
I'm an entomologist/evolutionary biologist by trade, but also very into "deep time" and geology as well. When I'm not looking down collecting beetles I'm looking down and collecting rocks and minerals. I first saw your Great Unconformity at Cody video a few days ago and have been slowly working through your catalog since (slowly as I'm really trying to absorb the content). Thanks for making mineralogy and geology both intellectually stimulating and accessible at the same time- I'm really *ahem* digging it!
Great news all around. Welcome to my channel. I hope you are liking the content. I'll have some new videos up soon: more from Yellowstone and a new series on rock identification.
Great content Shawn ,much appreciated absolutely excellent
Really interesting series on minerals so far. This one was fun for me as there used to be a muscovite mine near my neck of the woods, Inorth and east of Moscow ID.
Great presentation! I heard somewhere that clear mica was once used as "windows" for incinerators so you could see what was going on inside.
Yes, there were used on fireplace stoves and other uses. Mica is a poor thermal conductor so it doesn't transmit heat well making it well suited for such applications.
Thank you for another great video!
Very good 👍
It was very helpful Shawn.
Thank You😀
These are excellent Shawn! I wish my Geo 101 lab from decades ago was as informative.
Well done kind Sir. 👏
So fun! Helpful. And the rocks I've collected will make better sense now. 🙂
Are phyllite and schist with mica similar?
Very useful presentation Shawn. These sessions are more like a "morphological" tutorial and fill a gap not covered by the more theoretical channels on YTube. Beautiful samples and I'm especially impressed by the lepidolite. Oh, and I hope you've since found a razor, comb and packet of throat lozenges.
Nagging cough went away but I still look like an unkempt geologist. Sorry.
Thanks!
Thanks
I'm working my way through your videos. Absolutely amazing. I applaud you for sharing your knowledge. If you are ever in the UAE, look me up.
Wow, thank you! Much appreciated.
I have a couple of Coleman lanterns with mica globes. Sheets would be the width of one's hand....and perhaps a foot long.
Awesome and thank you.
Question: What textbook do you use in your classes?
Thanks, again.
We have moved away from print texts to online texts to keep costs down for students. Here is the one I use for GEOL 101: opengeology.org/textbook/

Why do i feel like they all taste good
Yeah hey Wesley question on the Micah what about coned cylinder shape micah
👍
What a strange product. I first properly encountered this stuff, and it was flaking off of something; and I thought that it may be the by-product of a chemical reaction and I was a little bit concerned and didn't wanna touch it. Now I understand after considerable research what this is, and it is very weird shit.

Asghar ali shah from Pakistan kpk peshawar thanks to you for the lecture its so great and meaning full I am new in this Field and I have mica from afghanistan for sale if some one wants abroad

I was told by a geologist in the New Hampshire that smoked Mica was formed in a high radiation environment. Is that true?
Hmm. I've never heard of "smoked mica." Smoky quartz gets its gray color from a radioactive isotope of cobalt (Cobalt-60). FYI, even though the smoky quartz has been irradiated does not mean that it is harmful.
@@shawnwillsey . LOVE that you read my mind with the FYI answer! Whew, I don’t have to throw out my smoky quartz specimens!! Which brings up another topic for the future: be sure to tell us if anything dangerous / unsafe for us to handle!
What about muscovite in botroydial habit?
Never seen mica that was botryoidal.
@shawnwillsey I have a couple on schists that have that bubbly appearance. Perhaps I used botroydial wrong. Thanks for responding. You have a new fan.
The name biotite suggests life -- does it come from some biological process?
No.
Thank you so much for these informative videos! I truly appreciate re-learning about rocks and minerals!
Thanks!
Thanks!
Thank you for this kind donation. Hope the video was helpful.
Thanks!
Very much appreciated. Thank you.
