Nick Zentner brought me here too. Thank you, Karin,I love yours and Mitch's new theories. I'm almost sold on it but I will have to dig more into it but it is intriguing to say the least. Bravo
Brilliant! Thanks to Nick Zentner for sending me here. I'm also interested in the eastern US where based upon Dr Scotese's graphics, a collision took place creating the Smoky mountains. About 300 Ma? The state of Georgia may have some artifacts including a large caldera like a navel in the middle of the state. And warm springs where President Franklin Roosevelt had his Little White House.
Zentner should be getting a royalty on this from the number of Zentnerds who have watched. Interesting stuff to be sure. NOTE to all conference hosts. If your presenter is using a laser pointer and you ever hope to post it on RUclips, get a pointer wide enough and bright enough to be visible to the RUclips viewer!!!!
What causes the bands of Pacific Plate elevations creating the Oceanic Transform Fault Escarpments? The sea floor North of the Mendocino TF is @2,500m higher than the sea floor South of the MTF.🤔 Can seismic tomography be detailed enough to show the mechanisms of the massive faulting? Can seismic tomography show detailed spreading ridge upwelling mechanisms? Is spreading ridge upwelling deep enough to enable continued divergent activity to the crustal material above it after its ridge subducts? Is the East Pacific Rise connected to the Juan De Fuca Spreading Ridges by deep subterranean upwelling via its former spreading ridge/transform fault system? This could explain the divergent Basin & Range Extension Province directly in-line between the EPR to the South, and the Mendocino Transform Fault/ JDF Ridge system to the North.
I think the 2500ft of elevation could be accounted for on strike slip faults because when they jog to the left the land on the right side of the fault gets compressed and usually goes up and the other side of the fault forms a pull apart basin and sinks down. A good way to see if this is the case with the area you are talking about is to look for a 1500-2500ft trough on the other side of the rise where it is slightly deeper than the surrounding ocean. There’s 2500ft+ peaks near me in California that are from the San Andreas jogging left, so even though the plates don’t move much vertically like a subduction fault, they still deform land enough on a large fault to create mountains and pull apart basins along transform strike slip faults.
On the doctor’s “Did NA override an archipelago...?” The seismic tomography illustration shows mantle/crustal activity well off the West Coast of NA listed as “slab walls.” Could this area actually be mantle upwelling feeding the JDF Spreading Ridge, both North and South of the Mendocino Transform Fault Escarpment?
On the doctor’s “Stages of Override” slide, she shows an “unknown” oceanic plate in Westward subduction under the Eastern Farallon Oceanic Plate. Curiously though, she didn’t address the type of margin connecting the “unknown” oceanic plate to North America; it simply shows a vertical margin. Is it presumed that since the model shows the aforementioned subduction, that the “unknown” plate is indeed oceanic? What mechanism would enable a continent to not only move an oceanic plate, but subduct it under another oceanic plate? Why wouldn’t the continent just cause the “unknown” plate to subduct under itself as it over road Westward? -Such as like the current JDF/NA scenario. Is there an example anywhere on earth currently validating this continental/oceanic passive/convergent compression assumption?
Would the arcs or large igneous provinces be formed from the earth trying to balance the gravity of the moon? Super Continents like Columbia, Rodinia etc antipodal to these trenches arcs and large igneous provinces?
As I watch this has had 812 views after 4 years,,, wow, what are most people wasting their time on rather than watching educational videos,,,, 7 billion on the planet and just 1 per 10,000,000 have watched this,,, ,or is that good,,,,, I always wonder when I am boating what are the other 99.999999% of my city of 5 million doing not enjoying nature, ,, ha ,

Nick Zentner brought me here too! Karin answered the question I had about the building of the Rockies
Me as well.
I heard about this lecture from Nick Zentner, too. Thanks for giving me a new way to view the geology of North America.
Nick Zentner brought me here too. Thank you, Karin,I love yours and Mitch's new theories. I'm almost sold on it but I will have to dig more into it but it is intriguing to say the least. Bravo
I'm sure she'll see an uptick in views today! YOUGOTTALOVEIT!
Talk about a sleeper presentation! Holy cow! What a privilege to observe such fascinating work in quiet.
Nick Sent her shared this to me. Thank you for a very interesting presentation
Yep, you gotta love it.......cheers Nick.

I'm behind the group, but thanking Nick Zentner also!
Nick Zentner sent me too. Excellent explanation.
Also doing my homework for Nick Zentner. Thanks, Dr. Sigloch. Fascinating!
Nick Zentner brought me here!
Me too!
Splendid!
I watched Nick Zentner this morning and this afternoon RUclips had this in my recommendation list.
...and me! fascinating...
Nick Zentner sending more today. What a fantastic new view under NA and new model. Thank you for all your work.

Wow! Very interesting ! Thanks!
Lets see if we can kick up at least 100 "likes" for such a brilliant presentation. Ronn (from Nick also)
Paradigm shift in progress !
I wonder how many views are from or due to following the Exotic Terranes YT live casts from Nick?
Thanks, helps me understand much better.
Thank you for sharing this presentation.

Consider yourself priviledged. I can't answer your questions, speculation would waste your time. Good luck to you.
now it’s over a thousand, have we all come from Zentner’s presentation?
Nicks still seding us 😂😂
