I had the pleasure of having Robinson Cecil as a professor as an undergraduate and she is a PHENOMENAL educator, researcher, and human being! I certainly consider her a role model.
Another excellent episode lifted to new heights by possibly the most enthusiastic and engaging guests we've ever had. If Nick ever needs a holiday, it looks like he's got a ready made stand-in who could take his place and educate, illuminate and entertain viewers from all over the world. The routine is virtually spot on now with a well crafted yet concise introduction to the topic leading into an in depth examination of who, where, what, why & how. This is how to teach!
Got to say that was one great story thanks to your guest speaker Robinson Cecil, she was amazing and yes you can tell she teaches too. very engaging. I hope you have her back. I strained my brain so hard to wrap all these ideas about challis magmas that I need a nap now. So glad I caught this one live for a change. and am caught up now. Thank you Nick you never disappoint.
Dr. Robinson Cecil was a MOST impressive guest on the Crazy Eocene series, one of the best. She possessed incredibly in-depth and insightful knowledge and was highly skilled at explaining the geology. Thank you Dr. Cecil! Nick, bring her on again!
I want a refund! This Ned Zinger guy hasn't mentioned The Craters of the Moon once! 🤪 Another great episode. Looking forward to Saturday's episode and hoping I can be there live.
Managed to simplify complex concepts for this casual arm chair geologist. Thank you! My quote I loved & wrote down from Robinson as I found it inspiring when I navigated thru some complexities at work this week (paraphrased): “My brain is not agile enough at once to juggle all though those pieces together and keep them all in the air.”
I've listened to many of this excellent Professor's talks / lectures, while coming from next to no knowledge of geology...🐒 He explains complicated things so clearly that even we uneducated poor folk can follow , and be intrigued .☺️ A wonderful teacher !☺️ Inspiring, entertaining, down-to-earth, amiable, the best combination ! ☺️ The intricacies of ancient geology are so very complicated !🐒🌋 So many things seem to have happened over millions of years ! Something happens, then maybe something else happens later, disrupting it, then erosion, over millions of years .... what a puzzle ! ☺️. It's also a tribute to the evolution of the human brain, that so much information, with so much intricate recall, can be in one person ....☺️ But even better, that that information can be presented in such an accessible , appealing way, resulting in many people , even though unacquainted with Geology, find themselves taking an unexpected interest. ☺️🌋🐒☺️. It is an unexpected , huge bonus during the depressing Pandemic, ( and while it takes such a time to fade...😢). The fact that you, dear Professor, have adapted, and found ways to connect with students, and wonderfully, with so many ordinary people , is so uplifting.☺️ Your huge subject of Geology seems like 10,000 jigsaw puzzles, all muddled up together ! I'll never look at cliffs, etc , in the same (ignorant) way again ! If a view comes on t.v. , say in a documentary, I now wonder how it was formed... I've always picked up pretty stones, e.g.,from beaches, and even polished them : they reveal lovely colours inside.... But the huge range of colours and patterns/ textures just shows how many variations there are, and that prompts the questions about how they were formed.☺️. I love your amiable style on the videos, you say, " Bye-bye, I love you !" That is SO nice ! I imagine all your students reciprocate ! ☺️💕. Who could want a better teacher ? ☺️ Love from England .. 🇬🇧💕🇬🇧🇺🇲🇬🇧 P.S., I have just had 3 years of cancer,( with probably single figures years left ) , and your videos are keeping me going ☺️, during constant terror of recurrence....😢 Learning can combat depression...I don't know exactly why, but your Geology lectures, and especially the country hikes, are the first thing I turn to every day ☺️ (4 March, 2022) I think it's your amiable, genuine, "no-nonsense" style : you say what you are thinking , in a natural way. No pretentiousness, just excellent one-to-one communication.☺️ Sending sincere, Platonic Love from England, to an extremely special person..☺️ Bless you, dear Professor. ☺️🇬🇧💕🇺🇲💕🇬🇧
Robinson did a great job explaining complex geologic terms in a simple enough way for me to understand. Can tell she is a great teacher like yourself. Great lecture as always.
Thank you Nick a million times over. This has been so refreshing and a breath of fresh air in the world today. It’s apparent how much you love your work.
Referring back to the 'Exotic T' episode, there was a page you showed pertaining to the Chelan Migmatite potentially being associate with the Okanogan Range Batholith and showed "ORB zircons contain older cores ~160 Ma" and "The CMC is older than other units in the cascades core, but is similar to the ages of the ORB ~108-115Ma". The older cores (~160Ma) fall in the same date range of the 148-161 CMB flare up, and the 108-115 Ma falls within the date range for the 102-114 Ma CMB flare up. Could the Okanogan Range Batholith be part of the Coast Mountains Batholith and/but somehow still ended up on the east side of the straight creek fault? The dates don't work with the Cascades or the Idaho Batholith, so it seems logical (given the dates) that the Coast Mountain Batholith & ORB could be related. 💞
Robinson is a brilliant scientist and is exceptionally adept at communicating complex geological processes. I intend to read everything she has published.
Really great episode today Nick. I loved Robinson and her work alot. I will have to re watch this 1 or 2 times again to understand it all lol great stuff
The times of these flare-ups are very interesting. 114-102 Mabp, is just *before* the Insular docked to NA. I think Nick (at the very end) nailed it with the westward subduction under the Insular superterrane explaining that. I love it!
Fantastic duo.I love the way Nick Zentner introduces the topic and his guest, Robinson Cecil. His questions are precise, her answers are clear. It is obvious that she knows how to communicate her knowledge at different levels (good for us !). I would recommend to (re)read her papers after viewing the replay. I try to keep in mind what we have learned so far about the tectonics and other magmas, and to reconcile everything with the datas exposed here. Tough job, but so interesting.
Robinson Cecil, started working in 2011 on Coastal Mountains Batholith by using "Just a Box of Rocks" to do Geology. Amazing, might find in Rock Hounds Collection of Rocks. Rock Hounds use Road Side Geology Books Hunt Rocks. Could Geologist use donated Rock Hound collection samples of area to do Rock Box Geology? Oregon Central Coast collects rocks in winter.
I very much enjoyed Robinson Cecil. Her work is essential to understand the Cordillera. I would point out , though, that her simplification of holding North America steady is a point that cannot be used to illuminate the tectonics and subduction. Obviously, the North America plate has not been steady for about 230 MY when the Atlantic basin began to open. That said, she is brilliant and I would very much like to her from about research in the future.
Another great installment in the Eocene guest speaker series! I look forward to a follow-up with the very articulate Robinson. I wonder how she might contrast the characteristics of the southeastern boundary of the CMB with the easternmost plutons further north. Is the rate of exhumation more rapid on the southern fractured area than further north where the tectonic plate is seeming more stable? (wonders this armchair student of geology)
Lots of words/phrases that I'd like to follow but can't! Where could I find some definitions? Still, I very much appreciate your dedication and absolute joy of your sharing all these wondrous facts of how everything we see is a story of amazing proportion. Since most of us just think what we see around us has always been here and will remain so. Silly us!
The ask...the only thing that came to mind is jello salad. Where you make jello, let it do a soft set then do another color jello on top. The only problem is you do it from top down and then invert it to serve. I'll have to keep thinking.
Hi Nick, I just have an observation. I found it helpful in GEOL351 when you emphasized the separation btwn the observations and the interpretations. Right now I am hearing the diff. Interpretations but I am not sure what all the new observations they are looking at and agreeing on before the storytelling starts. Can you clarify in one of the upcoming lectures please. Thank you for all your teaching. I am learning a lot. I love your willingness to admit you are still learning too. Stay warm this week.
If you like an analogy a bit like your chocolate cake, there is another popular cake. You put a vanilla sponge, a chocolate sponge and sometimes cherries into the same form, bake it and finally cover it with buttercream and a very thin layer of chocolate. The result is a delicious cake and a wavy intertwined black and white pattern with dark red spots when cut.

Seems like an analog for the batholith progression in the North Cascades is the walk of an inchworm on a twig. Suppose the inchworm is straight with the twig to start. It then walks up the twig with its back legs, arching its back (rising magma) before walking forward with its front legs, (leaving the batholith) as it again straightens out. The next step is in a different spot (for the next batholith). Maybe....
Saw the title and got excited that maybe he was doing a talk about SW Washington, but we don’t seem to exist. If it ain’t near Seattle it don’t matter. Would love to see some content about the geology of SW Washington.
I watched this a again after watching the CMB talks from the Baja series. The radiogenic Hf and 18O fraction results are consistent with something I think Margi Rusmore said: that you don't see old cores recycled at the nucleus of the zircons in the CMB. No old cores, not much old crust isotope signature. So everything is consistent with a consensus model: this stuff is all relatively new crust, probably from Island arcs. I think that might still be consistent with a fault mobilized rift remnant peri-continental ribbon though. The basement to such a thing would be new rift zone crust, and the arc basin continental sediment it carries might not reach depths required to be incorporated in these mid-crustal plutons.
Dr Cecil talked about batholith from 170 million years to 47 millions years old. Could there be an expansion and both east and west plates were filling in the gap? Or east then west were filling in the hole?
DID THE FACT THAT THE SIERRA NEVADA BATHOLITH CONTAINED MORE RECYCLED CONTINENTAL CRUST MEAN THAT IT FUSED BETTER TO THE CONTINENT THAN BATHOLITHS THAT WERE SWEPT UP INTO BAJA-BC even though the others may have formed at a similar time and for similar reasons?
I think that's kind of the story, but more like the Sierra Nevada Batholith was emplaced in older continental rocks whereas the CMB was emplaced in the Island Arc terranes that make up Baja BC. The Island Arc terranes were built from new crust, and the plutons emplaced in them reflect that by having no isotopic fingerprint from including old continental bits.
Here's the thing,. Sorry Nick bit atohicated man you have a way to express geological things in a universal way. push on your educational efforts are well worth it!!!!!!!!!!!!!!!!!
You probably do not recognize the name change when you've seen the maps. PUBLISHED DECEMBER 12, 2009: Queen Charlotte Islands will soon be no more. The archipelago will be officially renamed Haida Gwaii, Premier Gordon Campbell announced yesterday at the signing of a reconciliation protocol. The traditional name, whose English translation is "islands of the people," will now appear on all new official provincial maps and websites.
Out of curiosity, I wonder if there is paleomagnetic data along the X - X' transect on page 3 (249) of Dr. Cecil's 2011 paper. The batholith seems to run from -142 Ma to the west to -53 Ma to the east.
Just a thought -- wouldn't the mantle "wedge" above the subducting ocean slab that Robinson described as the source for pluton formation cancel out the model of a shallowly subducting slab that would be causing fireworks further inland during the Eocene?
lava lamp? kind of ... but it the stuff coming up doesn't melt thru the layers at the top. Some of those oil based water toys might be a better analogy.
Robinson must be a lot tougher than she looks. Field exploration of the areas she showed in the picture looks dangerous. Also if you are afraid of heights (like I am) it takes a lot of intestinal fortitude to even be out there.
Great show today! Robinson is obviously a natural for teaching, as well as research. Hope you can get her back for more in the future.
I had the pleasure of having Robinson Cecil as a professor as an undergraduate and she is a PHENOMENAL educator, researcher, and human being! I certainly consider her a role model.
HanSham!

I just got up from brain nap too lol Robinson is very intelligent and really knows her stuff.
Mm
Dr. Robinson Cecil was a MOST impressive guest on the Crazy Eocene series, one of the best. She possessed incredibly in-depth and insightful knowledge and was highly skilled at explaining the geology. Thank you Dr. Cecil! Nick, bring her on again!
I want a refund! This Ned Zinger guy hasn't mentioned The Craters of the Moon once! 🤪

My life is enriched because of your programs. Thank you.
Managed to simplify complex concepts for this casual arm chair geologist. Thank you! My quote I loved & wrote down from Robinson as I found it inspiring when I navigated thru some complexities at work this week (paraphrased): “My brain is not agile enough at once to juggle all though those pieces together and keep them all in the air.”
I've listened to many
of this excellent
Professor's talks / lectures,
while coming from next to no
knowledge of geology...🐒
He explains complicated
things so clearly that even
we uneducated poor folk
can follow , and be
intrigued .☺️
A wonderful teacher !☺️
Inspiring, entertaining,
down-to-earth, amiable,
the best combination ! ☺️
The intricacies of ancient
geology are so very
complicated !🐒🌋
So many things seem to
have happened over
millions of years !
Something happens,
then maybe something
else happens later,
disrupting it, then erosion,
over millions of years ....
what a puzzle ! ☺️.
It's also a tribute to the
evolution of the human
brain, that so much
information, with so
much intricate recall,
can be in one person ....☺️
But even better, that
that information can be
presented in such an
accessible , appealing way,
resulting in many people ,
even though unacquainted
with Geology, find themselves
taking an unexpected
interest. ☺️🌋🐒☺️.
It is an unexpected , huge
bonus during the depressing
Pandemic, ( and while it takes
such a time to fade...😢).
The fact that you,
dear Professor, have
adapted, and found ways
to connect with students,
and wonderfully, with so many
ordinary people , is so uplifting.☺️
Your huge subject of Geology
seems like 10,000 jigsaw
puzzles, all muddled
up together !
I'll never look at cliffs, etc ,
in the same (ignorant) way
again ! If a view comes on
t.v. , say in a documentary,
I now wonder
how it was formed...
I've always picked up
pretty stones, e.g.,from beaches,
and even polished them :
they reveal lovely colours inside....
But the huge range of colours and
patterns/ textures just shows
how many variations there are,
and that prompts the questions
about how they were formed.☺️.
I love your amiable style on the
videos, you say, " Bye-bye,
I love you !" That is SO nice !
I imagine all your
students reciprocate ! ☺️💕.
Who could want a better
teacher ? ☺️
Love from England ..
🇬🇧💕🇬🇧🇺🇲🇬🇧
P.S., I have just had 3 years of
cancer,( with probably
single figures years left ) ,
and your videos
are keeping me going ☺️,
during constant terror
of recurrence....😢
Learning can combat
depression...I don't know
exactly why, but your Geology
lectures, and especially the
country hikes, are the
first thing I turn to every day ☺️
(4 March, 2022)
I think it's your amiable, genuine,
"no-nonsense" style : you say what
you are thinking , in a natural way.
No pretentiousness, just excellent
one-to-one communication.☺️
Sending sincere, Platonic
Love from England, to
an extremely special person..☺️
Bless you, dear Professor.
☺️🇬🇧💕🇺🇲💕🇬🇧

Robinson was a fabulous guest! I continue to be amazed at the complexity of the geology of the PNW. Thanks again Nick for the education.
Excellent. Thank you both. Be well and stay safe.
Finally catching up on this video - Robinson was the best guest so far, and I've really enjoyed them all!
My late father would really have enjoyed watching you Nick!
Really great episode today Nick. I loved Robinson and her work alot. I will have to re watch this 1 or 2 times again to understand it all lol great stuff
Once again we've all be enlightened into the formation of the coastal mountains. Thanks Nick and Robinson.
Sorry I missed yesterday! I am glad to be here and, as usual, I am looking forward to learning something new.

Thanks Nick and Robinson, from the community.
Thank you Nick and Robinson for showing us a glimpse into your world.....looking forward to learning about my neck of the woods on Saturday!
Having worked in the inside passage on the north coast of BC this was even more interesting to me than usual. Thanks Robinson and Nick.

Here's the thing,. Sorry Nick bit atohicated man you have a way to express geological things in a universal way. push on your educational efforts are well worth it!!!!!!!!!!!!!!!!!
And another question, are there erosional sediments from the volcanics, etc. to the east?
Great show today!
So Nick, Where do the Queen Charlotte Islands come into this ? You haven't mentioned them much.
You probably do not recognize the name change when you've seen the maps.
PUBLISHED DECEMBER 12, 2009: Queen Charlotte Islands will soon be no more.
The archipelago will be officially renamed Haida Gwaii, Premier Gordon Campbell announced yesterday at the signing of a reconciliation protocol.
The traditional name, whose English translation is "islands of the people," will now appear on all new official provincial maps and websites.
Any comment on how the CMB dates and North Cascade dates interlock?
Out of curiosity, I wonder if there is paleomagnetic data along the X - X' transect on page 3 (249) of Dr. Cecil's 2011 paper. The batholith seems to run from -142 Ma to the west to -53 Ma to the east.
Great as always.
No you are very interesting to watch 🙂

Thank you.
WHY ARE THE CMB FLAREUPS SLIGHTLY OLDER AND OVERLAPPING THE SOUTHERN FLAREUPS?
Transect choices: No land travel possible. Think fjords. You will boat or you can't go. Good for rock exposure, though!
It was really a great lecture but I wish I could understand better if graphic explanations been associated with her descriptions on the subject
Today after almost a month I viewed this video four times to grasp what she says, Very interesting still
lava lamp? kind of ... but it the stuff coming up doesn't melt thru the layers at the top. Some of those oil based water toys might be a better analogy.
Thanks for chasing the rabbit warren.
This is the "I'm starting to realise" series part S!
How about the model for cracking crude oil??
It makes sense to me nick 👍
Robinson must be a lot tougher than she looks. Field exploration of the areas she showed in the picture looks dangerous. Also if you are afraid of heights (like I am) it takes a lot of intestinal fortitude to even be out there.
Often when I'm trawling the sediments of online forums, I also find myself wondering what causes all the flareups and lulz
