Jeff Tepper: Breakoff Belt

[@sharonseal9150]

The series format is working perfectly and so excited that we are getting these "supplemental" videos to go along with the series alphabet session! The interaction with geologists "on the side" is making a more digestible feast of ideas to go along with the main course. Thanks Nick, and thanks Jeff for helping us all learn.

[@CodyScarp-hl9ty]

Absolutely on point!

[@judischarns4509]

I continue to be amazed at how dynamic the study of geology really is. There is still so much to learn.

[@Mostly_Harmless99]

Please have Jeff Tepper on live or in these broadcasts more often in the Cascadia series. I always get a nugget or two that transforms my understanding.

[@Vickie-Bligh]

I appreciate this so very much, Nick. Thanks, Dr. Tepper.

[@Vickie-Bligh]

I love the poster idea.

[@garypaull9382]

More surprises! Cartoons coming and posters too. Another great workshopping session with Dr. Tepper!

[@diblust53]

This was very interesting! Looking fwd to the next 2 videos!

[@guiart4728]

Getting excited for the next few episodes!

[@jameslaughren1071]

Awesome! This really helped me understand how geologists determine what they are seeing and then contextualize into a hypothesis.

[@rosemarycorn2453]

Thank you both. Nick You have never been boring.

[@grandparocky]

Good to see you again Dr Tepper!

[@yukigatlin9358]

😃Oh my...!!✨🩷Love the ideas you both Nick and Jeff came up with a direction or two for the F, G, and possibly beyond! Especially, I'm excited that you could get hold of Jeff's students' poster works to share with us..., I would enjoy learning them very much!!💞✨ Thank you for sharing your sort of a workshop video!!

[@deantheot7296]

Thanks Nick and thank you, Dr. Tepper for adding to this conversation. I like where this is going! Take care.

[@TexasRoadrunner]

🎉 Thanks, Nick and Jeff .

[@raenbow66]

It always takes me more than one viewing to settle into the information. Now I get the pencils out and go slowly....which feels most helpful...and pretty darned exciting. How special is this, to be privy to the process? Just freaking amazing.

[@hankgraver6934]

Yes, better retention and understanding for all when replayed, once is inadequate when large content is conveyed. Wonderful use of time!

[@jscottmaclean226]

Your right Jeff, that was awesome! Thank you both!

[@janhelm3115]

Thank you both. Keeps my chemo brain working

[@Kevin-Tice]

Such a treat to see the process behind the scenes

[@xwiick]

Thanks for all the hard work on these videos!

[@DonnaCsuti-ji2dd]

Thanks for sharing this most interesting and informative discussion

[@Steviepinhead]

Such a fun episode! The brainwaves were emitting straight up off of my screen!

[@hankgraver6934]

Greatly enjoy the development of learning, through the organization of the information data to be presented. It allows all of us to think of how we convey or own information we want to share with those who are important in our lives.

[@pmgn8444]

Thanks Jeff and Nick. Looking forward to Episode F.

3:05 Peoh Point: "I like my hammer to be persuasive" (J. Tepper, esq., August 5, 2020)

[@SCW1060]

I really love to keep learning even at 64

[@KellyESEOr]

I like Jeff Tepper he seems to be a very decent human.

[@lowellpearson8782]

This is fun stuff thank you both.

[@raenbow66]

Hurrah! Faves!

[@mickmccard]

Wow, brain on overflow right now! Thanks!

[@solarwizzo8667]

Men of Rocks! You guys are awesome, involving the dumb public folk like me into deep Geo science! You blokes are Rockstars to me!

[@charlesflorian1758]

Great - another surprise video. Hope all is going well with Liz recovery. Great video BTW. Take Care.

[@DouglasBlack-ob9dy]

As a rookie - I would like to see samples of the different formation and where they are on the map

[@bgclo]

Jeff, great to see you! I bet the Gold Mountain samples Ken made me collect back in 1989 are still lost deep in a cupboard in the Department! They're probably the key to this whole thing, so you should look!

[@mr.morelock]

As a 'casual' enthusiast... I love these series. Not only for the information, but for watching the Science happen. I wonder how many professional Geologists are avid followers of these videos... Sure there's a small knot of local contributors Like Jeff Tepper, Gary Paul, even Shaun Willsey... but for Professors and Docs whose field this is... are they interested? Are they vying to get interviewed... are they even accepting of this format outside the world of Academia and Government? Goodness knows I'm grateful, and there's a thousand or so live viewers for the live streams. How about the pros? Better yet... are you pissing anybody off with this? 😬

[@barrym4079]

I think on the contrary. As Mike Eddy said, it's a great way to engage the public that pays the bills that fund these projects. Not to mention Nick is making "Rock Stars" out of these geologists, who probably aren't used to the public recognizing them or their work. I personally think it's a win win situation. I know I thoroughly enjoy learning geology in my retirement. Putting the fun in funding. lol

[@edithmatheson1828]

This is a good workshop.

[@stephencarter1442]

I watched Duncan 1982 and I see a pattern when the the rotation is idle is when we see heavy flow of basalt Layman view. Rookie from the peanut gallery,

[@brianfinch827]

Thank you bath for sharing this very informative

[@pinkerdroit]

Cheers! 👍

[@LillianArch]

You had me at Granite Falls!

[@akaEageralto]

Me too! I've been looking for a good explanation of the Hanson Lake Rhyolite for years--since I first learned of Nick, actually.

[@SingersMom-rx8wt]

Just finishing w/ Erin and Coco then as I'm closing down there's Nick and Jeff with another great session! Hmmm, Christmas break and Nick has been kicked out of the "recovery zone". Lucky us! Lucky Zentner Family!!

[@edithmatheson1828]

Sounds like Thursday is going to be a long one!

[@cyndikarp3368]

Excellent planning session. Thanks for including us in this process. Does any of Siletzia have hornblende?

[@inqwit1]

BADR: absolutely. Was that one of the backyard conversations?

[@sandythixton4611]

Nick, how about adding your short field video to the video collection of the series that you made at Mary's Peak near Corvallis which is part of Siletzia.

[@BudKnocka]

if Siletzia is so heavy it snaps the farralon plate…would it dive so steeply that the flat subduction margin would become vertical aka pizza box stack transforming into a strike slip fault? Transporting Yakutat northward?

[@steveboguslawski114]

My amateur understanding is that when a subducting slab is attempting to pull a plateau that is too thick and buoyant to sink deeply the tension eventually breaks the slab. Siletzia jammed the old trench and the Farallon slab pulled it as far down under as it could when it broke off. After the slab pull is removed the edge of the plateau that was pulled under is free to rise and reach isostatic equilibrium. The apparent steepness of the contact could be (would be) affected by rebound, erosion, and flexure of the plate(s) in response. The original dip angle might not be preserved, and I think in most localities it isn't. Throw in any change in plate motion after the breakoff and the area might be undergoing compression, extension, or transform motion too, adding another complexity to the sequence. I guess I am saying that what is observed today has been distorted by everything that has happened since Siletzia docked.

[@fishonkz996]

I think the correct formation is the Lyre, not Lyell. But I've been wrong before! Jeff made the same correction after I commented, Lol!

[@barrym4079]

If the impact of Seletzia reversed the river flows, they must have reversed and consolidated into the Columbia River. The Columbia then maintained its path through the Cascades as they rose. I have learned on other lectures that the Columbia River is older than the Cascades, so this must be the case.

[@wadehines9971]

See if any of his students/former students wants to join you for a quick (2-3 minutes) walk through of their poster. Those things are generally a lot of work to put together for little reward. Any student who is interested might do well from the opportunity.

[@Snappy-ut4bj]

👍

[@robtippin9111]

😎

[@wadehines9971]

I love the comingled theme of __catching a falling knife__ respective to how scientific interpretations evolve with emerging data. This based on comments creeping in around 15 minutes. So the what people were thinking, some new data, evolving models with their controversies and champions, and thinking about what new developments may clarify things. That's far more exciting than conclusions. That's way too big of course but nuggets in service of that is pretty much what you do anyway.

[@StewartSmith-g4f]

Tillamook Volcanics?

[@skyecooleyartwork]

Formation names in Washington need help. Too fragmented. Someone needs to step forward and start connecting like with like. The time is right for a new stratigraphic framework for your great state. Who will it be? WGS? UW? An outsider?

[@wadehines9971]

I'm reminded of something I heard 45 years ago in immunology research when it was emerging fast and confused. Scientists would rather share each others underwear than share each others nomenclature.

[@gregoetting]

WHAT IS THE NARRATIVE REGARDING THE HOT SPOT COMING ONSHORE WITH SILETZIA? WAS HAPPENS BETWEEN 51MA AND 17MA?

[@Townie001]

Surprise.
