I beleave I received a selfevaluation of A+ during the Zentnerd GEOL. 351 2021 AND I'm closely monitoring Geldingadalir Volcano, Iceland So No Chumstick Formation Homework! I'm watching the "Effusive Fagradalsfjall Formation" or "Mondlukaka Cake" flow over the Tundra. A new appreciation for the CRB's German Chocolate Cake

Ralph is a DAWG. Super nice guy too. I'm drawn to research scientists and instructors who don't exhibit the haughtiness, sanctimony, and arrogance usually associated with scientists and teachers who are obviously brilliant but can't tie their own shoes, yet carry themselves as "elitist." This group here, including our host, possess none of that. These are the scientists and instructors I wanna hang with; I feel smarter than I am by just being around them.

Thank you for bringing this report From the Field. At first, I thought my eyes were playing tricks on me since the timestamp showed that it just had been posted. Your camera shots over the mountain ridges were absolutely stunning but you could easily see this was not just a "walk in the park". Thanks again for giving us more than just food for thought on a late Saturday evening!

Seeing this detective work sure makes me regret dropping out of college because I wasn't determined or focused enough to become a geologist! What an awesome combination of cool science and field research!

@briane173 6 ай бұрын

I find myself feeling the same regret at times. Looking back there were lots of reasons why I didn't stick with college that had a lot to do with some fundamental "flaws" in my character -- the arrogance of youth being one of them, along with some ADD and perhaps a dose of depression. Had I been more mentally disciplined I might have discovered geology at an early enough age where I could've done something with it, because it has certainly piqued my interest now in my old(er) age. We can always say "it's never too late;" but nowadays it is so cost-prohibitive I couldn't even _start_ now, let alone finish. But hangin' vicariously with Nick and these preeminent scientists is the next best thing, and it's kept me alive after losing my wife of 42 years. Keeps my head on straight and my brain flexed.

I sit here and wonder how a research geologist home-based at Perdue couldn't fall so in love with the terrain being researched that she pulls chocks and moves to WA. As geology goes, Perdue might be a mecca for studying and processing geochemistry, but the area has some pretty boring geology by comparison to the North Cascades. I live right near the Columbia Gorge and Mt St. Helens and just can't get enough of the geology here.

@thirstfast1025 3 жыл бұрын

A cruiser vest is much more practical most of the time (for me anyway, as a prospector). It allows you to distribute your load across your whole torso instead of putting it all on your back. Notice her difficulty maintaining balance on soft, uneven ground (4:22). For me (so probably not the same as what they're doing) a typical sample would be a couple softballs. We often take 2 at a time, one to analyze (ie assay, and therefore destroy), one to keep as reference. I can carry ~30 samples in my vest, which I guess would be about 60 softballs worth of volume (though rock is typically going to be denser than a softball LOL!). Cheers!

There's a Revolutionary War Period cemetery on my property. The markers are sandstone with that nice varnish. The oldest readable date is 1769. Also, got a ton of river rock from The Kanawha River. there are vesicles in softball sized, rounded basalt, beach sandstones, large crystal granites, so many different layering in the sandstones. Some have iron fused to the outside layer.

At 13:15 there is a bright white, tuffaceous looking cliff under the ridge in the background. Then you head over there and look back, I think, and you’re looking past Mike Eddy at 22:55 when you zoom in, and there it is, what sure looks like a nice cliff of that ridge supporting, silicified tuff facies that Erin was talking about, right under the ridge you must have walked on but couldn’t see from the top... Hope they got some good samples. Erin seems like a skier, the way she navigates all the loose talus. I noticed Ralph had some highly developed footwork on the loose terrain too.

Is "Arkosic" a catch-all term for sandstone in which feldspar predominates and other minerals less so? Is there a cut off like 60% or does the term still apply if the feldspar was 35% and none of the other minerals are greater than 34%?

@andybreckenridge4461 3 жыл бұрын

Google "QFL diagram" (quartz-feldspar-lithic) and you'll see how sandstones are named according to mineralogy. There's not just one QFL diagram everyone uses, but in general, quartz dominates almost all sandstones (because it's so resistant to weathering), so even a rock with 25% feldspar and 75% quartz might be called an arkose. Depending on whether the name is just a field description made with a hand lens, or based on inspection of slides of the rock with a microscope, will also make a difference as to the accuracy of that rock name.
