Great information! Day late dollar short comment: I was listening with headphones and while I'm not a technical type, Jerome was all left earphone at a reduced volume. Others were stating they could not hear him.
Finding these lectures has been such a happy little accident! I'm now planning a trip to all these places from your videos as a sort of classroom and summer vacation for my kids.
Gotta love technology when it gives us sessions like this. We are so very lucky to learn geology in such a fun format from the best! Thanks to Jerome for joining and teaching on a fine Saturday morning. Thank you Nick...great as always! (PS really appreciate the little chapter time slot things (or whatever they are called) so we can re-watch certain segments easily)
Nick, I can always count on you to, make an hour of geology, fly by like 15 minutes, I really liked the addition of another enthusiastic geologist, thanks to Jerome for taking time on a Beautiful Saturday morning to tell us about Vancouver Islands geology.
I am enjoying this so much. I became fascinated by plate tectonics as a child as soon as I was old enough to read the back issues of National Geographic that had been collecting since I was a baby and I'm still fascinated over 50 years later.
Great to hear from a BC geologist. It was a couple of years ago or so I found you Nick after looking for a geologist to explain BC, geologically speaking. Thanks for this.
Thank you, Nick and Jerome! Absolutely fascinating! This series will be a worthy successor to "Exotic A-to-Z"! The new technology adds a whole new dimension to the livestream, and the comments in the chat are also extremely useful and interesting!
Nick, I say we keep it roughly contiguous and finish the Wrangellia event before we move on to Siletzia. Clearly, the limestone is A HUGE clue on the Wrangellia formation location... "warm, shallow sea". 😉 It has to be much further south than it's final, current location. Loved the segment with Prof. Leseman! The in-office, representation, layout of the stratigraphy was awesome.
That was great and I was left with a lot of interesting questions . I am looking forward to the next session about Wrangellia. Good job Nick with sharing your livestream with Jerome Lesemann, it was perfectly done. You have become a geolo-geek !

Since I've started watching Geology by Nick, I've become addicted to German Chocolate Cake/ gummy worms, gained 100 pounds and developed a gut.....lol. Thank you Nick, awesome class.
Keith from The Blue Mountains west of Sydney. . . There's a ' Gummy Worm ' off the south west coast of New Zealand, found it while hunting for the bolide crater in that area.
I’m blown away by your latest program,Nick. Learning that the rocks from THE FAMOUS SICCAR POINT WHERE GEOLOGY WAS BIRTHED BY DR HUTTON are found up there on Vancouver Island! (If I am understanding this right) We are all so lucky to be watching this. Thanks for showing us the rocks, Dr Lesemann. I am so glad you are getting the recognition from these experts, Nick. -Leslie from near Boston.
I knew about Caribbean, but.... I have a good friend from a MMO game I play who teaches biochemsitry at his local universiity on Aruba. 🙂 Oh, and it's Kehr -gway len
Meryl cringes at writing his opinion to a fellow geologist but once it’s read out loud to your followers, Nick, it serves its purpose! Don’t hold back on your opinions Meryl! Thanks
I recall listening to a double-PhD talking about how too much information at once can be like trying to drink from a fire hose. There's no time to process and digest anything because new stuff keeps pouring in.
Daaaaaang, I missed it. With so much going on today I just missed it. :-/ will watch it post lifestream now. Edit: After watching it: That was great!! Thanks @Nick and @Jerome for both being here so early according to your time zone. Wonderful job you both. And @Nick: having a guest worked out great with mellon!! :)
I an so glad i keep watching these videos again and again.Now i have at least an idea of what may be happening and also something that i can understand.
Perhaps, a Northerly Terrane transport mechanism can be currently seen @SoCal with the Salinian Block/Terrane being pushed by Baja via the East Pacific Rise. There is evidence that it is also pushing the Franciscan Terrane into the Siletz Terrane like a subterranean train in reverse, causing the NW rotation.
I think that the Mother Nature auto pilot worked: “Terrane, pull up. Terrane. Pull up.” I do have a questions about the sponge cake formation. 1) magma upwelling under ocean seems like it would cool really fast, so not sure how basalt flows would form. If there were lots of faults, it would seem they would be solid chunks entrained in the flow. 2) if the sponge cake was formed over those millions of years, wouldn’t there be sedimentation from sea life found in the sponge cake, to make vanilla rather than chocolate cake. Love the series so far.
Oops, one more question. Being from an engineering background, the heat balance seems out of whack. The magma upwelling needs to lose a boatload of heat above the crust, and the formation below the crust needs to lose the same boatload but not sure where that would go. I can see the top losing heat to seawater, but last I knew, the magma is somewhat warm and fluid, so losing heat underneath is mystifying.
@@rwilson1125 if by loosing heat underneath You mean below-crust-part of sponge cake, I just assumed it formed above and was pushed down by weithg of newer layers.
I watched it last fall but now I understand what you are saying 3 events 3 land mass's on the first event, 2 land mass's on the second even, and one land mass on the third even which is called Siletzia which was the younger of the 3 even that had to do with the Yellow stone hot spot. Was Wangellia built by the Yellow stone hot spot as it moved east like hot the Hawaii Islands moving over a hot spot, or maybe even built by that hot spot? Just wondering is North America sitting on the hot spot that built Wangellia?
Is the YHS a stationary hot spot like Hawaii or has it moved? If say Siletzia was above the YHS 50Ma, with NA moving WSW, I can't see Siletz moving only a couple hundred miles NW without some Kula or JDF help. If stationary; Why would the YHS "shut off" 51Ma and not be making more "PNW Traps" today? The more you teach me the more I realize I don't know, thanks! ;^)
.. When YHS went from goin thru 7km ocean crust to at Cali coast going thru now subducting at angle 7km crust plus 20km mainland crust, this can stop YHS from breaking thru especially as the subducting crust is going east so fast it only partly melts before moving eastward off the hotspot. So half of scholars think it's normal for YHS to go quiet at a subducting coastline... As for Siletzia, either it was made off Cali then in ocean got sent NNE or it was made off Oregon and the YHS was somehow up there maybe when a HS starts it may be off the straight vertical from source 500km down... Hope that makes some sense, ha. ... Big idea is W US is geologically dangerous, too thin of crust, not a safe place, ha, Flood Ballasts could restart anywhere west of Alberta to New Mexico, so hope geologists figure out these mysteries... Just my guesses.
I am partial to the spreading ridge theory of the formation of Wrangelia and the Intermontaine, after all, where is the northern branch of the East Pacific Rift (spreading ridge) if not transcended by the over-ridding North American plate? Just sayin''!
I’m re-watching this after the following series’ discussing rest of Eocene and most of Baja BC. What confusion I see regarding where the PNW terranes and LIPs started gets cleared up for me by Karin Sigloch’s observation that North America has overridden a good bit of the former mid-ocean rise (vs the southern bit that South America hasn’t). How much of the crazy bits of the PNW originated from places that now reside in the mantel below North America?
If you want to investigate LIPS beyond what Nick is presenting today, have a look at William Sagers lecture on 'The Largest Volcano in the World-Mid Pacific Ocean'. Sager tries to explain how LIPS (Shatsky Rise) are classified from plumes, triple junctions. It is quite interesting!! Sagers Lecture: ua-cam.com/video/8bhUEYNNr1Y/v-deo.html
Hi Nick. If you read this and get a chance, could you post a link to where you bought that Tharp map? I see some on Amazon, but i'd like that canvas material if you know where to find it. Thanks for what you do.
So the oceanic plate is happily subducting and we hook our LIP on the edge of the continent. The top is accreting but what happens with the bottom? Do we just slice off the top and carry on down? Seems like if the base of the LIP stays put, you have to rip the subducting plate in "two".
Haven't finished watching yet but it seems reasonable that the Yellowstone hotspot was creating these plateaus out in the Ocean before it went under the North American plate... Flood bassalts seem to be associated with hotspots.
Nick if you decide to continue with Wrangellia is it possible to 1) study of the " Pacific Rim deformation boundary between Wrangelli and Siletzia . 2) Study of the Wrangellia limestones ? Are they truly a Karst environment due to faulting/folding/collision with terranes to the east or south?
I don't know if this is right or wrong and would appreciate an answer but despite the fact that this is primarily an igneous story aren't you downplaying the sedimentary accretion on top of your sponge cake. I would think there would be significant sediment and erosion involved with the sponge cake's multi-million year journey.
I'm watching this a year and a half after it was streamed. I keep thinking, what would break up a plume (slice) like a cake? That's massive linear forces. In Africa, the pulling apart isn't as linear as most plate divergent boundaries. So maybe the worm analogy is the best explanation. They are thinner and easier to tear chunks off of and send them north. Let's see where this goes... 🤔

India started moving after the breakup of Pangea and docked with Asia 50-30Ma, same timeframe as Siletzia. Could India be a LIP formed during ,say, Gowandaland or b4?
Good day, Siletzia - Yellowstone hotspot LIP Wrangelia - Northern east pacific rise LIP??? (when did North America run over the EP rise?) Cache Creek - if not a LIP, why not a Hawaiian-like island chain but larger??? Tony
checking in at almost 4PM Nick time and already 3496 views and 663 likes as for me I finished my last day in the diamond mine and only saw one diamond (.38 brown) that someone else found. so now I've got to take all of my gravel home to sort it out and try and find a diamond.
Ned uses his wooden NW Rotation tool by pushing up on the bottom, but doesn’t account for where the tectonic energy from the South comes from? The class should be introduced to the California Terranes (Sierra/Great Valley, Salinian, and Franciscan,) and become more acquainted with the EPR and it’s Northern off-sets in the Gulf of California. It’s doing much more than just pushing the West side of the San Andreas North, it’s a game changer.
Great format to be able to hear from geologists who are conducting research on the topics that Nick is trying to explain! Please keep it up!!
Great information! Day late dollar short comment: I was listening with headphones and while I'm not a technical type, Jerome was all left earphone at a reduced volume. Others were stating they could not hear him.

Who gives Nick a thumbs down? Really? Nick is a paragon of knowledge and an amazing person.
Disgruntled students
People who hate everybody!
Flat Earthers?
@@nevyen149 That's who it is! You solved the mystery! :-)
Thanks for these videos. I'm fascinated as a laymen with hearing not only the details but how a geologists thinks about these processes.
It is fun to hear that so many from around the globe are watching.

After all these year's, I'm still listening sir.
That's because I love your Channel sir !🤘😎✌
Thanks Nick and Jerome! Combining your knowledge sets makes geology even more interesting.
Had to leave earlier, back to finish, Jerome's info was great and rock samples were fantastic.
Well, fooey! I realized it was on just in the last 10 seconds. I got to see you say goodbye. Luckily I can see the replay!

at this pace, you risk becoming a tectonic plate yourself.
It's not gneiss to fault him for a seismic shift in your habits to a sedimentary lifestyle.

So Vancouver Island didn't exist before the docking? The Pacific Northwest is always changing.

Oolong Java as l understand it is the largest LIP.
At one time Kerguleon was largely above sea level.
The region around New Zealand is now considered continental crust.
Perhaps the LIP are caused by call them burps that are not associated with a mantle plume but basically rise through the mantle as a blob.
Sorry for the high brow terms.
FUN TO INCLUDE JEROME
is there any way you can publish your graphics?
India started moving after the breakup of Pangea and docked with Asia 50-30Ma, same timeframe as Siletzia. Could India be a LIP formed during ,say, Gowandaland or b4?
The "hand" samples in Jerome's collection look more like a cubic foot.
Even the Hawaiian Ilands have a rift....that can split the island.
Good day,
Siletzia - Yellowstone hotspot LIP
Wrangelia - Northern east pacific rise LIP??? (when did North America run over the EP rise?)
Cache Creek - if not a LIP, why not a Hawaiian-like island chain but larger???

Maybe not the East pacific rise, but the front (east end) of the Farallon plate.
Or possibly an earlier plate (pre-Farallon)
