You know I may not be able to impress people with my knowledge of geology ,but for myself I know that I think about things differently now. 🤔 That's all I wanted. Thank You..
Great analogies. I have tilts, wrinkles and folds, fissures and maybe even a few slickenlines and foliations. I certainly have faults. Dark brown surface hair is now bleached white. Both gneiss make noise when I walk. My lenses had inclusions until the ophthalmologist did her thing. I'm probably Cambrian aged. Also known as older than dirt.
The Great Unconformity, where time is missing. In the Grand Canyon it's 1.2 Billion years of it where you were standing. This was a very interesting and fun lesson professor.
I would say that in the example of the granite and the sandstone, the jointing in the granite has not affected the sandstone, which I think it would have if it had intruded into the sandstone first and then cooled and jointed.
I live in Houston, right next door to Stafford. Not much geology in our area as we live on 20,000 feet of mud. Got to go to the hill country. Better yet, go out to west Texas where there are the remains of volcanoes. If you like rocks you might come to the Houston Gem and Mineral Society meetings.
Thank you, Shawn. Once again a fascinating lesson. I surprised myself with getting 100% on the quiz today. Your teaching style using examination and processes of elimination really help me working through the questions. I like the mix of diagrams and photos which helps cement the ideas on my older mind.
Super video - loved quizzes. Was a lot of fun taking things learnt from previous episodes, seeing how they fit together, and then to be able to apply the knowledge to interpret the different formations in the field. 👍🏻
One year into the University of Willsey, and I got ‘em! Got my crib sheet and Can hardly wait to check out the rock layer relative ages on my next hike!
Hi Shawn, I really enjoy your presentations, and teaching methods. I was oblivious to geology until I got into photography and started walking our little coastline here in the Bay of Fundy in Nova Scotia, Canada. I been playing catch up ever since, and your help has given me new appreciation of the area. You give me some understanding of what I see on a regular basis, and a reason to keep learning about geology. I have a few local mentors, but still trying to understand the language. :-)) I just wanted to say thanks for the help.
I'm glad I'm not the only one with a pic of being waaay too excited about the Great Unconformity. You win on using a RURP for scale though (10:35). Cheers!
Mr. Willsey, sorry I’ve been extremely busy and haven’t seen any videos in quite some time! Time to get my scientific geology on again! Thank you very, much sir! It is an honor! 🧠💪⛏️❤️✅♻️🫡👍👍☀️🌙🌋🏔️⛰️💡⏳📱📖🔍🧐⚖️💎🛢️🎉💌
You got me on the one that needed more information, but I got the rest of them right. I’m surprised. My 67 year old memory is not what it used to be. Very interesting learning experience. Thanks👍🏻
Loved this! Aye, wish I wasn't a basket case with learning disabilities back 50 years ago... just needed time travel. This was beautiful! Once had a handful sized piece of granite which looked like exactly this [Colorado, i think].
Great video. I learned a lot from it. One thing... 13:30 Be careful about dissing those about their grade, while calling "F" a number. 🤣🤣🤣 21:50 Option number D 🤣🤣🤣🤣
very educational. I liked your rurp keychain in the inclusions section. how many people know what a rurp is? I never used them, but I have used Chouinard Crack N Ups in Eldorado - on Practice Climb and Arial Book. scary protection. Mark in Boulder
Prof. Willsey - is the principle of lateral continuity not useful/irrelevant to relative age dating? I'm correct in thinking that is the 5th principle of stratigraphy, yes?
This was a fun lesson, good job. Bye the way I did get one question wrong due to my not reading it correctly although I did have the dike sequence correct. Caught me at my weak point of taking tests, I tend to know the answer but not re reading the question is the downfall.😊
For the purposes of dating the rocks, how old were your shoes? 🙂 Why would metamorphic rock be older then granite? Since metamorphic rock is either created by pressure and/or low temperature, wouldn't that rock ceased to exist if it had been surrounded by the magma that cooled at the right rate to create granite? Also, if created by pressure, how would pressure be applied before it was surrounded by rocks (granite) ?
Metamorphic rock is created by pressure and/or *high* temperature so it doesn't necessarily get dissolved when surrounded by magma. The pressure is applied by being buried kilometers deep under the surface. That's where metamorphic rock usually forms. So the sequence could be: 1) Metamorphic rock forms deep under the surface. 2) An intrusion of magma into the metamorphic rock takes place and shears off pieces of that rock, including them as xenoliths into the magma. 3) The magma cools down, forming granite. There could be a considerable amount of time (thousands or even millions of years) between 1) and 2).
Was just thinking about this video. Nick Zentner just dropped a video about Goat Rocks and some amazing stratigraphy created (in part) by tephra. Exquisite video of a mountainside cutaway by landslides showing exactly what you were talking about.
Concerning the granite, metamorphic and dike, is it not possible that the metamorphic rock was caused by the intrusion of the dike into the granite? Edit: I suppose if that were true, we would see the metamorphic rock all along the dike, not just at one end.
Hi Shaun thare is a young gay on utube his chanel called post ¹0 from Mane u s he has a rock he found can u explane how it got the shape it did it looks like bark on wood Thank u

i love doing the quizzes
This is more interesting than any thing on television. Great stuff thanks couldn't be better
50-50 on my answers! I would love a Geo-Logic puzzle. I love these types of investigative quizzes. Thank you! ❤
Love the puzzles and stories that the rocks give us.
Thank you for putting these lectures out there for us to enjoy. The quiz was great fun. I'll look at rocks differently from now on.
I loved this lesson. Thank you very much!
Awesome, thanks Shawn.

This was so cool! After your explanations, it was easy to pick out the younger and older features. I have always wondered how to do that! Thanks!
Glad it was helpful!

Yep. Got me on the "need more data"!
You made things so easy to understand. Thanks a lot.
Wow, hurrah! ❤ This is so fun, pulling together several bits I've heard but not really learned. Geo-logic! I love this. And will practice. 👏🏼❤️

Great class tonight.
What happens if I do not find anything or where anything where off the granite
With “which rock is the oldest” its the granite. The granite has faults and the sandstone was laid on top.
I like the better microphone sound.
Well done that man 👍
Fussy old sound engineer here 🧙♂🔊😉
Hey thanks. The funny thing is the old one was pricier.
Cake? Cookies? Suddenly, I really like geology.
Thank you!
Hey Shawn
Prof. Willsey - is the principle of lateral continuity not useful/irrelevant to relative age dating? I'm correct in thinking that is the 5th principle of stratigraphy, yes?
Lateral continuity is less useful for relative ages but still important. I teach this in GEOL 102 (Historical Geology).

we use the same principles in archaeology :)
OMG... and that's your grade for the day. Nice one, teach😂😂

Oh boy.
@@shawnwillsey lol... so much for my career in Stand-up Comedy. Thanks Shawn, your Geo 101 series is great!
..and then there' s the Sweet Home Alabama version of relative dating. 😜
Oh jeepers. Don't go there.
I got one wrong - the one that needed more info.
Hi Shaun thare is a young gay on utube his chanel called post ¹0 from Mane u s he has a rock he found can u explane how it got the shape it did it looks like bark on wood
Thank u
The one under the one on top is older most of the time... 99 percent of geology explained.

in the question which dike is youngest how do we know dike A or C did not come last?...

How do you know which came first?
