    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.

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.
    ☺️🇬🇧💕🇺🇲💕🇬🇧

    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.

    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!

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.

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.

  • @wallacethomas9844
    @wallacethomas9844 2 года назад +3

    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?

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....

    @timbyrne914 Год назад +1

    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.

  • @willbradley7450
    @willbradley7450 2 года назад +2

    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?

    • @timbyrne914
      @timbyrne914 Год назад +1

      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.
