Erratum: I said moonstone was a labradorite. There is a variety that is labradorite, but most moonstone (like the one I pictured) is actually oligoclase feldspar.
I really like how clear She explained things so even person like me(Who dont know absolutely anything about rocks) can understand it
Hey Patrick, I'm Scott, I'm one of the undergrads that Emily mentioned in the video,
Just want to say that this was an amazing video!! I love sunstones, I'm so glad you made this video
Awesome, great to hear from you! I bet it was a blast working with Emily.
Well done Patrick!
I have never been to the sunstone collection area, but I hope to change that in the coming year, and watching something like this gets me excited about it.
Thank you.
Swing by and grab me on the way!
I appreciate the subtle humor in your explanations. Keeps it spicy.
This was a very informative and well made Video Patrick. I learned a lot more than what I knew and had already absorbed previously in my research on SunStones. And I'm sure my journey will continue to take me to parts unknown. Thanks for all the time and effort you put into this subject so that we may all glean from the education.
loving the deep science on this channel. ICP-MS, argon-argon dating, plutonic intrusions, NO DUMBING DOWN! Good! More!
Small correction at 5:20 - the reactor is bombarding the sample with neutrons, not e-'s.
great info- interesting theories and engaging to watch someone so interested in their interest/work talk about it
Very Nice.
The Folk at spectrum mines are quite pleasant and Denise is super knowledgeable and helpful. Lady with the Golden Eye's!
Don't forget the sunscreen and lots of fluids!!!
Interesting it's still a question on formation and dispersal.
Does anybody have a good beginner fauceting machine quality enough to do Sunstone?
Have a quart jar with some 50 pieces worthy of cutting. Couple watermelons that got it all!!
Back to video.. Golden Eye's!
That's news to me about the disassociation of the southern sunstones to the Steens event. There's a lot of mystery sill inherent, it seems. I like seeing her coloring book illustrative explanation of the hypothesis, what a great interview. Did she do her dissertation (or more papers) on Sunstones? I'd love to read that/them. The video is a fantastic and informative overview of sunstones with some delicious details for those of us who have spent quite a lot of time with these. Cheers!
Emily's work might have touched on it, but some of the science illustrations were from Badur (2022) Auburn University Master's Thesis which Emily helped out with. That's available online, and I'll link it in the description.
The coloring book was by me to try and visualize the concept simply, rather than only hearing about Emily explain it.
Really fun to listen too, thank you.
Great job on this vid man.
Wow, this is a really cool interview!
Went to one of the private mines in the Plush deposit some years ago. Overall a good experience. Bring friends to help search the belt for the material. More eyes and hands means more material recovered. Very rural though, about an hour drive on dirt roads to get to gas. So bring a tire repair kit, food and water. Oh and a hat. :)
I like how enthusiastic she was… especially her last sentence about experiments & smashing sun stones… “this one would work” 😂
Fascinating and well produced video, thank you for all your hard work on this one! I love the family of feldspar/labradorite, and was fortunate to grab some beautiful faceted stones years ago. This helped to answer a lot of questions, and maybe bc I’m always curious, brought up a whole lot more. It’s super interesting to learn that the ages of basalt varies between the physically distant mines in Oregon! And, then there’s the mystery of the composition of the stones and different areas within the stones! You interviewed two very knowledgeable people and I didn’t get really lost as much as I thought I would ;) When Emily mentioned the copper pipe verdigris, it got me to wondering about sweat on a pipe, and although I’m having some trouble finding the right manner to explain my theory, I wonder if different water sources could be part of the explanation for the difference in colors? I will be embarrassed if this was addressed and I missed it haha. I love my stone’s a bit more now. Which I hope to get at least one mounted in precious metals someday!
Karen's worth talking to if you're interested in getting sunstones set.
One of the things I really like about the sunstone story is that it isn't settled science yet. We have these very identifiable features and yet we still haven't been able to unravel the complex processes involved in their formation. There are lots of good hypothesis floating around, though, and I think it's a matter of chipping away, making observations and analyses, and having the right person (like Emily) to pull them all together.
@@DonohueLabs one of these day’s I’m going to have Karen set a stone for me, I just love her art! I was sort of into collecting faceted gems for a while, so it’ll be a challenge to decide which one’s haha. Yes, I love learning all about geology and the stuff that isn’t knowledge set in stone (no pun intended lol), are the most interesting to me. Like the snow ball/snowflake (?), periods on forming our planet (hopefully I got that right? The remembering is the toughest part). Ty for replying back! I love the content you post on your channel!

Makes me think of that Oregon professor that does geology and toured the liberty gold mine. That amazing professor which I forgot the name did a video on the rock mountains. He’s like actually saying the Rocky Mountain formations aren’t necessarily set in stone or the theory was but now it’s being questioned as new data and tech is used. It’s super interesting to think a 50 year old theory or something maybe questioned. Seems more rare tk have big changes or theories overturned today. I remember my college physics professor a decade ago said that basically. He’s like if you really want to change things or make a massive discovery that really rare or harder to do.
Wow wee Very Informative and thought out. A pretty lady that knows rocks. wow To bad I am an old man. Thank you for this video
So........... Could it be dichroic like Tanzanite, maybe?
Because that's kinda what my Zultanite (Andalusite) looks similar to.
Geology rocks! 🤘🤓🤌
Good!
Do you have some sunstone with good red and green that you could record with a dichroscope to show the pleochroism? Should be easy enough to check that idea out
That was really interesting! And totally, if I had a big beautiful sunstone with color, I wouldn't want to give it up to get smashed for data! And if I were them, I would have a tough time doing the smashing! Yet, I quiring minds want to know! That is totally fascinating! And me, who isn't a geologist, or a mineralogist, or even a gemstone collector! But I followed the conversations, no problem. And when she first started talking, I thought for sure it was all going to be over my head! But now I'm hooked! I want to know how the sunstone gets into the basalt if it didn't form in the bugs? And then when and where did the copper come from? Thanks Patrick. That was another really good documentary and you have my wheels turning! Outstanding! Another fabulous documentary, in the can!🎉
Thanks, Lisa! Emily really has a gift for explaining things accessibly, I'm grateful I found out about her. Though it would have been hard to avoid her, since she's one of the few doing this research!
The basalt flows altered the sunstones. They predate the basalt that picked them up during their eruptions. This is what causes the dating of the sunstones themselves to be all out of wack. You’re trying to date volcanically altered materials.
Also they figured out what makes the green..
On the 200.00 machine? I tried to get ahold of Matt I think it was through his email but it would not let me. Really need the transfer jig and the lap riser. I have that machine! You can actually see it I got it up on my channel. I try but I don't do that well.
learn about electromagnetism and it'll all make sense
Pitiful, Crayon Drawings to illustrate the geological process @07:18 minutes. Mixed with cartoonish, coloring pages, it just makes for a confusing demonstration.
Surely, this could have been illustrated much more professionally and more legibly ?
Not on my budget
Someone has a truck of this soft garbage and they are trying to spark interest and jack up the price. GOOD LUCK WITH THAT
Seems to be nature's heat treating of the Sunstone.
Copper was introduced either by pressured steam or like in Yellowstone, ponds, boiling water with some steam explosion, depositing micro amounts of copper by pressure into the Sunstone.
Always thought that geology, crystalology, and mineralogy should be learned as one. That way, you could be as close to knowing as possible, the what, why, and how of any formation.
