Around the 18 minute mark, Nick asks, "Am I wasting your time?" To which, I say, "NO!" I can see how a person could spend an entire day there, making notes and taking pictures (and samples) and just marveling at the scene. Thank you, Nick, for taking the time to go there, and allowing us to go along. Many, if not most of us, understand that just because you're a geologist, doesn't mean you have all the answers, no matter where you are in the world. But, because you are, you're able to help bridge the gap between the viewer and the rocks. To me, "it's time well spent."

I’ve really been enjoying Professor Zentner’s series. Most geology programs are just too general, covering a broad topic like “Plate Tectonics”, “Volcanism”, “Earthquakes”, etc., but viewing his videos I really learn more. I’m a geologist, I don’t want to just rehash my first “Introduction to Geology” course!

Nick. You are correct. Most migmatites are generally avoided like the plague. At least there's more on it than the ones in Ontario. We got no one studying the migmatites in Ontario. We can't even decide on how to classify them. I divide them into 2 main types. 1) Migmatites where melting has obviously occurred and penetrates the host rock and present within the unmelted part (arterite migmatite). The second is like what you are looking at, where any melting is hard to see but the migmatite was right at or really close the melting point. I call that venite migmatite.

Some of the roadcuts where these rocks are exposed with fresh surfaces have that wonderful, characteristic, swirling-band migmatite texture. That’s how I spotted them, just driving by at highway speed. This texture captures the exact temperature and pressure conditions where these old gneisses were partially melting to form new plutonic magmas. It’s not something we get to see very often, most migmatites are now deeply buried in the roots of our mountains. These rocks are special!

I remember when Nick did his tour of the CWU campus and showed the various rocks of Washington state that were on the grounds, I immediately fell in love with the beauty of the migmatite and I asked where I could find some. As soon as Nick entered the area where he sat down I recognized it as the place where I first saw the migmatite and I just assumed the leucocratic veins were quartzite(I assumed every white vein was quartzite back then) so it was really awesome to see that Nick was in the same place I was at a couple years ago when I first explored the Chelan migmatite. still one of the most amazing and beautiful rocks I've ever seen and it makes me want to go back to Chelan.

Thanks again, Nick, for another fun geohike! Yeah, I can see why geologists like to overlook this section. Can't wait for the Baja-BC series where we hopefully find out where this leetle terrane pops up south of Washington. Looks like it all went through a mix master of layering, squashing, heating, uplift, and sideways squishing with intermittent faulting and traveling just for fun. Oh, the poor kids who could have this on a test! Glad to hear they are collecting zircons and some are trying to map it at least!

Great video and questions Nick! I am also excited about the direction your teaching sessions will go this fall. I am a retired math teacher and my son is a research materials engineer. We have watched all your videos since March 2020, and when he visits we take out the Roadside Geology guide and head out to explore the places you talk about. All this information connects, and the more I hear about the geology of Washington and the North Cascades, the more it makes sense to me. In fact, I have learned so much from you and your guests that on my own I have started reading "Earth Materials: Introduction to Mineralogy and Petrology," by Klein and Philpotts. Thanks!! Keep it coming. Mary

There's something that looks similar to this migmatite in the mountains south of San Joaquin Valley, in the mountains on the south side of a valley called Mil Potrero the SW side of the San Andreas Fault. The SAF runs along the north side of Mil Potrero. My parents used to have a vacation house in the area so I used to hike up to the waterfall where the migmatite is. Higher on the mountain the rock is more like granite. I find myself imagining that this came up from the west coast of Baja California and I wish I knew more about the geology of that place. There's a big hook on the west coast of Baja CA called Punta Eugenia, which I imagine as the place from which the south end of the block moving north along the coastal right hand faults of Southern CA came, and another on the mainland of Mexico at Puerto Vallarta which has to be the former home of Cabo San Lucas.

@19:20 use a laser scanner to map the rock surface geometry. Take multiple camera angle shots all along that surface (drones, maybe?) apply the surface texture image to the rock geometry earlier captured, then model the color contrast boundaries as semi-rigid sheets extending into the volume behind the surface. Well, that's what I'd try, to start.

Nick, for Baja BC can we keep a RUNNING TALLY of proposed fault offset distance on a physical chart on the wall that is compiled incrementally during the winter session? Would love to see each session reinforcing these thoughts of proposed movement, but individually emphasized and even Challenged, to then reveal both a "conservative" estimate and a "plausible" estimate of proposed translation over a specific time window. Keep following your instincts, absolutely love this channel! And don't be so hard on awestruck Nick , sometimes the lack of the right words can convey the significance just as well if not better.

Thanks for the video. This video reminds me of making fudge. When you start adding the marshmallow cream you get all kinds of weird swirls. Maybe as it was forming it just didn't get mixed as well in all places. What did the area look like back then? Were the rocks going up, was the land going down exposing the rocks, was the land going down and the rocks going at the same time? Did the rocks come up because of the fault and change the fault? Was this area weakend because of all the faults?

Nick, from reading about migmatite on Wikipedia, the light a dark striping comes from "exsolution" of two components that were formerly a *single* melted composite material (presumably, of much older origin than the exsolution event), which then separates into the two main components, forming the bands. According to this, we are *not* looking at leucosome (light) intruding into melanosome(dark), but rather it is the result of leucosome and melanosome materials formerly dissolved within each other, becoming separate macro components with the swirling or banded appearance that you (and I) were marveling at. If the above is correct, does the exsolution event occur during the elevation process? Start as buried granite 30 km down (?) and ends up at the surface, as migmatite?
@EonSurge Жыл бұрын
I don't think so. Migmatites are the result of partial melting, the melanosome never melts and you therefore don't get exsolution. The felsic minerals which will melt as their fusion temperature is lower will form the leucosome in the rocks. Most of what Nick has shown us is in fact in-situ melt, but some large bands are, as he says, coming from the squeezing of partially melted rocks underneath, especially at the last spot he was on. Partial melting is quite simple: It needs to happen deeply and some hydratation is usually involved to lower the fusion point. I don't think it happened during the elevation process, no reason why. Now, I've only worked with 2,7 Ga migmatites, it's interesting to look at in far younger rocks!
