Very useful video for amateur rock hunter like me.thanks and regards.

Geologist need to pick a root language. Latin or Greek. Just pick one. We only need one. Thanks :)

I have a question: How can i differentiate between a matrix and cement (macroscopic)? Can a stone have both?

awesome

Id love to take you hiking and or rock hounding. 😊

Wonderful and very informative video. I have subscribed, thank you Allison.

Any software to find principle stresses of conjugate fracture, fold and fault with respect to dip and dip direction

thank you I have an exam tomorrow I needed this

Thank you for sharing it was very helpful.

Thank you for the Wonderful video.

Just Wow🎉❤

Nice video. The chineese have started their own deep borehole. We'll see how far they get.

Hi

Very helpful vid, thanks!

You’re a natural teacher, this is excellent!

👍👍👍👍👍 very good

Hi Just wondering, can you do a video about gemstones and the term gems and minerals, and what's the difference between these two. I think they interchangeable.

Igne in Sanskrit is called Agni, means Fire. That means rock from Fire (magma)

❤❤

Cool!

Thanks Allison , it was really useful and one of the best explanations about rock classification I've ever seen. I'll be grateful if you put a like for the chart .

15:31 But surely we can hear

Good presentation

Hi...would you like please to do a video about the determination of the principal stress axis of a reverse fault....

Very good lecture Thank you!

Great lecture

You lost me at English system, think you were looking for imperial system

Thank you for your time doing this video for the people. I am learning on my own. Could you give me some keys to differentiate an amphibole from a pyroxene (horblende vs augite) . Thank you

I’m about 10 minutes in. Really articulate so far. Easy to follow. Stepsin logical order and helps build on each subsequent step. Kudos.

You did a nice job explaining concepts of metamorphism. Thank you for making the concepts relatively easy to understand (at least at the time, Ha!), it's mostly a matter of keeping them in mind when thinking about the rocks. The examples of the representative rocks is enlightening, and helps place to rock to a process. So appreciative. Thanks

Well explained which makes it so easy to understand. Also very easy to listen to. Thankyou.

What a comprehensive explanation!! I'm in love of Geology now because of You. Please continue making such videos, they are very useful to us students

I thoroughly enjoy listening to your channel. I have recently signed up for a BSc in Geology through OU. Could you recommend any reading material which would be useful in the future. Regards from Northern Ireland.

fantastic...very clear video helps along with your knowledge

Thank you ma'am 😇, well explained !

thanks a lot :) <3

Thanks, please make a video on structure core logging on Igneous rocks, I am your great fan as a teacher to me!!!

👍👌👌

Thank you. You are one of the most articulate and informative instructors that I've encountered. I will continue to follow you. Keep up the good work.

thank you

I love the explanation for the rocks! I really love that you elaborate on the important things! Thank you so much, I’ll be coming back to this video many times

Amazing. Don't want to commit to sitting in class for 3 hours a week with homework and exams, so this is how I'm educating myself on geology. And I'd say you do a damn good job.

Mid-Atlantic ridge.

Great thanks

wow cool.i dont even geology

Excellent, clear, concise and informative, thank you Allison.comment

Great and helpful video! Thanks.

I think it is harder when you start your career to know the difference between sand, clay, silt and rock. Honestly you should make a video on it in the field.

You're doing more good in the world than you realize

Interesting, thank you!
