Holly crap dude that was awesome. You gave it to us with both barrels blazing, "Yeh". Really great scope, great regional tie in. Great brief explanation of the unconformities, monoclines, anticlines. We use to say, it's like trying to stuff 100 pounds of _ _ _ _ in a 50 pound bag, but you did it. My hair hurts. Thanks so much for sharing with us all, out here in amateur land. We love geology too, we're just to burnt out to remember all the stuff the pros remember. We are so grateful for the help. It is frankly a frustrating mystery why millions more people don't fall in love with geology. I use to work for a civil engineering lab years ago, going to quarries to do sampling in Colorado, and that's when I caught the bug, with the first piece of petrified wood I pulled out of the quarry wall with my own two hands. It was thrilling, and I've been maniacally trying to piece it all together for the last 35 years. Lectures like this help out so much to give us a big picture story. Please do more.
I live in the Pacific Northwest. I’m not a Geologist but do enjoy learning about geological formations. Because of watching your video about US east coast geology formations, I learned more about US west coast geology formations in my backyard. Congratulations on a well produced and educational presentation on Virginia geology. It served for this observer to contrast the differences and similarities between US east coast and US west coast geological formations.
Been watching Professor Nick Zentner's series on WA State (grew up in WA) and wondered if there was similar material on VA geologic history. Very glad to have discovered your class. Thank you so much for sharing the geologic history of our state!
Me too and was really excited when I searched VA Geology to find this video! I stumble across a wide variety of rock types when I'm fishing and hiking and really want to understand what's possible to find here in VA!! Loved this!
Great Presentation: Illustration of the tectonic migration of the crust components and their joining , combining , subduction and mountain building, layer accumulation, contortion and layering over time provides a comprehensive picture of how the continents we know today came to be.
This is the best course on Virginia’s geologic history. I took geology in collage and this short video covered the subject much better than my teachers did.
Wow, This presentation was mouthful, but well worth listening to. It was packed with lots of general Geology, formation of rocks, and contential history. Very well done - A++. Just amazing.
Great video. I am happy this popped up in my recommended videos. I learned much more than any 'made for TV' style video could teach me in the same time.
I love East Coast Geology so much! There is so much that went into the land we see today, which is wild since we sit in the middle of a Passive Margin today.
This is a fascinating peek back through the deep history of the Commonwealth, and illustrates the depth of the history that surrounds us. It is hard to wrap one’s mind around the timelines involved, but it certainly does help to give some insight into some of the most common geological sights in Va. really well done…. Hard to imagine this is a college project!
Sick vid, currently doin a project on VA geology and found this extremely enlightening. I’m actually from Culpeper, it’s always great to hear we are known for something besides breaking Superman’s back and paralyzing him from the neck down.
I see no recent comments but I want to let Callan know his video on The Geology of Virginia is still be viewed an enjoyed by many. I just finished viewing it for the second time. Thank you for developing and posting it on TH-cam.
8:50. This is Walther's Law of Lateral Succession, wherein vertical strata reflect horizontal deposition in certain settings. Nearshore are river seds, farther offshore are muds and carbonates. This is seen in cross sections when compared vertically.
Absolutely fantastic presentation! Not being a geologist(so take it with a grain of feldspar) I find it to be both comprehensive and fairly concise but not so much so as to cater to the short attention span style we see so much today. Thank you so much I really enjoyed watching your video.
Terrific presentation, a lot to absorb and definitely worth watching several times. I lived in Virginia for 15 years back in the '80s and '90s, hiked, walked, biked and drove over much of the territory. It would have been great to have the knowledge contained in this video. Well done!
I love this video. Tons of information combined with a great presentation. I hope you will consider doing similar videos for other state, specifically Tennessee would be of interest to me. Great job.
Very well done. Thank you for this presentation!Was the post-Cretaceous rejuvenation of streams a result of regional uplift, which gives us the inland plateau on the far west side?
This is wonderful material for those like me that are just curious in Geology. Jour job as Nick Zentner's are invaluable. Just a suggestion: try to group the videos in categories in the playlist area. It'll be easier to go from the begining building up knowledge. Cannot thank you enough for your work. 👏👏👏🙏👋
All very interesting. Thank you very much. I did a college paper about the geology of Gettysburg and the armies march through Virginia. You brought back a bunch I'd forgotten. Thanks again.
The Iapetus suture can be seen in the Isle of Man and in IReland near Shannon - where I grew up is the former ocean floor and volcanic island arc that outcrops, in hte Lake District.
I ride mountain bikes in DuPont (North Carolina mountains) and I'm always in awe of the huge granite slabs that are exposed. I see straight lines cut into the top of these and can't figure out what did that? They are mostly less than an inch wide but very straight.
Your slide showing Stratigraphy of the Valley and Ridge Province illustrates the Mauch Chunk, Pottsville, and Conemaugh as part of the Acadian Orogeny. The Mauch Chunk, Pottsville, and Conemaugh stratigraphic units form part of the Alleghanian clastic wedge, deposited by the Alleghanian Orogeny. In West Virginia at Spruce Knob, the Price Sandstone (upper part of Pocono) is overlain by the Greenbrier Limestone (passive margin unit) , which is overlain by the Mauch Chunk and Pottsville (Alleghanian clastic wedge stratigraphic units).
Ollie Costello here. Have you seen this video by Bob Hatcher? It lines up nicely with yours. I really enjoyed listening to this VA video. I did my thesis in the Carolina Slate belt near Columbia, SC. Similar but very different. VA geology is the best :-)
Excellent! Now when I'm driving to and from the Outer Banks, I will have an idea of what I am seeing. And Michael Domansky is right, you and Nick Sent her would totally rock!
I have to say, that was damned interesting. I never knew there was such a diversity of rock formations in the crust. Now I shall have to find out how the UK was formed. There are many examples of folding in the exposed rock sediments where I live in Liverpool. Great stuff.
The geology of the Isand of Britain is quite interesting. It even hosts the remains of two supervolcanoes, Scafells in the ake District and Glencoe in Scotand. And the Scottish Highands are actually a continuation of the Appalachians.
Greetings from the BIG SKY. I've always thought that plate tectonics resulted from asteroid strikes. The book I read by James Mitchner told of the Chesapeake Bay well.
In Calvert Cliffs there are rocks with shell fossils that are covered with iron oxides, how would these be formed? Combination of shells covered with an iron oxide crust?
Hi Dr. B. Was there a gold-bearing back-arc basin associated with the Chopsawamic Terrane, and would that make it analogous to our Georgia Eastern Blueridge province ? Thanks so much!!
At roughly minute 20 he discusses two different ages in the same rock, saying that the younger one got raised to a temperature of about 400 degrees, no enough to reset the zircon and lead; but wait, how did the temp rise to in the 400s then? Does anyone know? (Enjoying your presentation Callan!)
I can't get enough of visualizations of Geology; esp video, but diagrams must suffice. In the next few years more and more CGI will be applied to Geology; and I can't wait. It's already been done for Astronomy; as everyone (with an interest in science) remembers their first time in a class trip to planetarium watching Theia hypothesis; the theorized protoplanet that collides with Earth to form the moon. We need more CGI artists to get into Geology, damnit!
Yes, this video is quite old but I only found it today and because of Iapetus and Atlantic I am now wondering how is it that first the oceanic plates subduct and then later a mid-ocean ridge appears in the same place? I've heard that plate tectonics is created by convection of the earth's mantle. So I imagine that something rises in one place in the coat and therefore has to go down in another place, which breaks the coat into a kind of bubble? The panels float on the mantle and are either pushed apart or towards each other. Do the places where the material moves up and down also move?
I wonder if you could make the closed caption feature work for this? I'd love it if you did. It's fabulous for 90% of us, but it would make this great lecture more accessible!
I found this looking up the formation of the chesapeake bay since i live in maryland. But now i know basically the whole history of virginia and maryland i guess. Idk if marylands geology is different im assuming its similar
Your example of the Appalachian mountains during the Crustacean as shown toward the end of the presentation doesn’t seem right to me. Isostasy should have played an important role as the rivers etched out the rising mountain chain while promoting the event by removing material from the mountains.
I didn't notice it probably due to the poor frequency response of my listening device. This is great advice though and I second Gunther's recommendation.
LOL a year later I found this video, started watching it...and heard the popping again got up to say it needed a pop shield, and voila... I already said it a year ago.
I know everyone pronounces mafic 'may-fic,' but I personally think it should be 'ma-fic' (short 'a' sound), because the word is a portmanteau of 'magnesian-ferric,' and 'magnesian' is NOT pronounced 'mayg-nee-sian,' it's 'mag-nee-sian,' short 'a' sound. Shaking up the geologic community one syllable at a time...
If this was 300 hours long, I would watch it all. And then probably watch it again.
Same😀‼️
You should team up with Nick Zentner to produce revolutionary kick-butt content
Yes! I've been looking for the Appalachian story and hopefully this is it. I'm interested in PA and it's coal fields as well.
I took his class and I can say that he is a great professor! If you are not into Geology, you will end up liking Geology after taking his class.

This was by far the best summary I have found and I have been scouring for a source that ties together information in a coherent manner. Thanks.
I found this from listening to Piedmont Blues, wondering what piedmont meant. I had no idea about any of this. My mind is blown.
I find stuff like this fascinating, especially when I learn something new…
I have a geology degree and enjoyed this well-done video. Thanks for putting in the effort!
What an amazingly informative discussion! Thank you so much, Callan, this is great work.

Brilliant video and teaching here, you explained the various orogenies well in a way most can follow along with.
Truly fascinating and entirely "accessible" to the lay person. Thank you so much. Love me some Petersburg Pluton, LOL.
So nicely done. I haven’t thought about East coast geology much since my orals and the interpretative framework makes much more sense now.
This is super, super interesting and the annotations using electronic marker really do aid one’s understanding.

Excellent detail and explanation of Virginia geology.
Thank you for all your hard work! I learned something today 😊
Outstanding presentation...
Hi Dr. B.
Was there a gold-bearing back-arc basin associated with the Chopsawamic Terrane, and would that make it analogous to our Georgia Eastern Blueridge province ? Thanks so much!!

Metamorphism - mountain building, crustal thickening and deeper burial of this unit or else intrusion of nearby magma.
absolutely amazing!

wonderful, I wish the study of history included modern (written) history, prehistory, geologic history, cosmologic history....
greetings from the permian basin, cool video, enjoyed it.
I wonder if you could make the closed caption feature work for this? I'd love it if you did. It's fabulous for 90% of us, but it would make this great lecture more accessible!
Spectacularly good! Thank you!
This answered a BUNCH of questions I had.
Very well explained. Do you ever look at weather patterns? They tell a fantastic story of earth's past.
That was very well done. I applaud you!
Great vid. Interesting and informative. Thanks
came for the rocks from Nick on the rocks thank you
You should make your videos like sci show or crash course chemistry. Look em up on TH-cam! You'd make an awesome person to do crash course geology!
Great video. Thanks for doing this!
I love geology and plate tectonics ❤️‼️
This is awesome!!! Thank you so much!
I found this looking up the formation of the chesapeake bay since i live in maryland. But now i know basically the whole history of virginia and maryland i guess. Idk if marylands geology is different im assuming its similar
Yep, pretty much the same stuff! Geology doesn't stop at political boundaries!
This was very interesting and informative.
Great presentation. Thanks for this.
Excellent analysis. Kudos
Excellent presentation
Interesting, informative, enjoyable!
would anyone be able to point me towards a similar video about new york?
Very good teacher! Understandable! Thumbs up! #116
That was wonderful! I minored in geology in the early 80's and we've learned so much since then.
very well explained, and very well illustrated. chapeau!
Very well done!

Great video thank you
Excellent!!
Good vid! So Mach good info in just 30 min.
thank you!
How do you know the continent was called Rodinia? ;^)
Excellent presentation. 😎👍
fuckn bad ass I fuckn love geology!
love your lecture.
Your example of the Appalachian mountains during the Crustacean as shown toward the end of the presentation doesn’t seem right to me.
Isostasy should have played an important role as the rivers etched out the rising mountain chain while promoting the event by removing material from the mountains.
Great fun!
You need a pop shield on your microphone. I found it terribly distracting.
