I have to write a narrative story about a rock. I got an amethyst and so here I am doing my research, my teacher better be ready for a heart wrenching story with a rollercoaster of emotions.
Yes, in fact I did happen to form in mineral deposits seeping into a porous rock cavity formed by co2 gas trapped inside molten rock! Thank you for asking!
My love for minerals started when I was 9 and my teacher mentioned quartz. My only friend was ill that week so I spent recess looking at different rocks, trying to find some. I read a book on geology, I bought crystals everywhere I could and on a field trip to a museum with a geology room I took several hundred pictures. I stopped obsessing for a while but now it's even worse than before thanks to these videos...
I really love the enthusiasm you have for rocks it definitely makes your videos enjoyable. I hope you keep making more! I do want to help out with some of the facts/science you talk about in this video in an effort to make things more accurate and a bit less confusing. One thing was the discussion of how geodes form in lavas. It was a good description of how geodes can form in basalt and andesite (two different types of lava), but it isn't how geodes form in rhyolitic lava. Another thing was how you said quartz crystals are generally found in igneous rocks whereas silica is found in sedimentary rocks. You sort of treat silica as different from quartz, but quartz is made of silica (silica = silicon + dioxide). Also, quartz crystals are one of the most common crystalline structures found in geodes from sedimentary rocks with good examples being Keokuk Geodes and Moroccan Geodes. Finally, you talk about how a geode is different from a thunderegg. The explanation for how a thunderegg forms wasn't very accurate and the whole "geode vs thunderegg" thing really confuses the relationship between the two. A thunderegg is a specific type of rock whereas a geode is a feature that any type of rock can have, that feature being a hollow interior lined with crystals. Whether the inside of a thunderegg is solid or hollow doesn't change the fact that it's still a thunderegg, so a thunderegg with a crystal-lined hollow interior is a thunderegg that's also a geode. This happens with septarians too. Most septarians (a specific type of rock that forms in sedimentary formations) are completely solid on the inside but some can develop hollow interiors lined with calcite crystals. Paul Colburn wrote a really great book on thundereggs and his theory on how they form. He spent decades digging thundereggs from locations across the western US and has done more to advance our knowledge of thundereggs than anyone else. I would suggest checking it out if you can, it will help with understanding thunderegg formation and also why it's inaccurate to focus on the "geode vs thunderegg" comparison.
This is a superb explanation, much better than Wikipedia’s article on geodes. I really liked the explanation of how the mineral-laden solution enters the hollow portion to deposit the minerals and form crystals.
I remember watching a show on the science channel about that one cave full of ridiculously giant crystals once. I was fascinated (yet terrified...cave phobia) by that place so i was researching it and read someone call that place a giant geode. WOULD that giant crystal cave be considered a geode? It would also be cool if you could do a video on that subject sometime!
Geodes are a secondary feature (not formed at the same time as the host rock) and typically have a tough exterior "rind," even in the case of Brazil and Uruguay. Basically, you'll get a massive layer of a mineral or mineraloid (quartz, agate, ...) completely enclosing a void. A nodule, or in the case of agate a thunderegg, is similar but completely infilled. A vug is any open space in rock containing crystals; they can be primary or secondary.
We went on a class field trip to a museum, and it had plenty of these pretty stones. I saw a basket of them at the gift shop and just had to have one. I've never seen one up close before!! They are my favorite stones ever
I find some nice geodes around where I live. I found a whole one in a rock and cut it out with a grinder, then cut it in half and it has blue-grey layering with a small cluster of glass-clear crystals at the center. The outer shell is very rough and abrasive to the touch, would make a good pumice stone. I have also found fragments of red-white and green-white geodes.
My fascination came from climbing a long steep trail in the Cascades and 'steeling' from an old gem claim that I had to bushwhack to. It was a side rout to a mountain i wanted to climb., originally a gold prospectors trail, very steep. The thready barely there trail was known to climbers and listed in an old anglers book (1920ish) but the start from a logging road was deliberately obfuscated. Below a high pass, a faint side trail led along talus and brush down to a small forested lake. Above was another 600 ft side peak: Rock face on one side, crystal rich brown iron oxide containing talus on the other. Quite the steep climb using my ice ax up the duff/moss/needles/dirt to the talus field. Some boulders almost looked like red clay and broke apart easily. I pulled some nice quartz there. The 300 foot open face (I repelled from top) on the other side was partially exposed by mining I think but might have just been there. The rock massif was an intrusion area with small blast caves and natural looking fishers of mixed old sedimentary rock and silica rich volcanic rock and odd voids. The junction held the purple and green geode goods, a lot of color, but surprisingly not much obvious gold. Obviously hot mineral rich water got in there in multiple events to form larger crystals inside voids, then uplift and erosion to expose it, as well as volcanic activity nearby. Cool stuff. edit: Nice video, thanks.
I love this video mainly because I'm a science freak and I absolutely love anything like this I have a collection of colored Rock's and I own a bunch of sea shells and 3 geodes and my grandpa used to work in the mines so he has a geode he found himself and a small bag of minerals and and other things he got in the mines and I absolutely love it ❤️ I give this video a 👍🏽
In terms of geode formation, it is not true that it's more likely to get Qtz crystals in igneous rock and microcrystalline silica in sedimentary rocks. Also, only the Brazilian deposit has amethyst geodes. The other localities mentioned did not form in the same way (the amethyst did not form in secondary features like geodes, but in vugs).
Geology of Gems & Minerals oh nothing really, it's the name of a formation I learned from some other RUclips video on geology, rock formations & minerals. He had called it "Gneiss" pronounced as in the word nice. To be clear, I'm not disagreeing with you at all, nor was I being mean, so please take no offense. Sarcasm doesn't bode well with the comments on this very well for me does it? Actually, it may not have even been sarcasm, but rather a pun. A very dry pun intended joke. I should just delete it. Sorry!
I own some ground on a mountain in south central Kentucky (hallsgap) and you can't walk 2 feet without seeing them I have found thunder eggs and everything else but since I read a story about a gentleman finding a diamond in the Carolinas so I'm wondering if the hundreds I've found if maybe(a big maby) I haven't found a diamond too. I didn't think diamonds was found in the United States? Someone please help an old man out?
online states that not any natural occurring diamonds have been found in Kentucky.. But on a different note, during the 1760's Jonathan Swift buried a heaping $150.000 in silver bars and ore somewhere along the breaks of sandy river in a cave.. Said to be along Highway 80, near Elkhorn City around the base of Pine Mountain..
@@gitv2987 ,,yeah I know in wolf County they have a Johnathan swift festival and I have read about a few people finding silver coins and traces of gold around the big sandy river,I think they call it glacier run off or something like that. At least I have a huge sup8of thunder eggs and different shapes and color crystals. Oh well I can dream
It’s like Freshman year with Ms. Dean all over again. Too hot can’t pay attention. Came here to learn how geodes are formed, I literally have no idea what you said.
being born in the womb of my mother, not sure what kind of minerals surrounded me but I know we all have minute minerals inside of each of us, iron, magnesium etc. literally we are formed from the dust of the earth as it states in Genesis.
Hi Nethan! It has everything to do with the pyrophoricity of iron. Iron combines with oxygen very quickly and generates heat when it does so. Rust happens slow enough and over a large enough surface area that the heat is negligible. However, if tiny particles of iron with a larger relative surface area to their mass are exposed to oxygen, they oxidize very quickly and cause enough heat to ignite flammable materials such as tinder or gas. The quartz or flint is used because it is harder than steel and can scrape particles of iron off of the larger mass fine enough to ignite.
Why when I broke my good open it looked like it had a good start amd then like died and kinda weird rusty like bands with empty space between the bands
She was so cute haha... I'm supposed to be a grown man & never admit when something is cute, but come on... She hesitantly sang Prince like a shy girl, irresistible

Best explanation ever with the most enthusiastic and clear information. Gray job!!
I'm not a geode yet, but I àm full of hot air.
So in 5 grade science we just learned about geodes and now I have a big thing for gems. We watched this vid in science that day.

The Naica gypsum crystal caves are considered vugs, not geodes.
Geology of Gems & Minerals oh wow ! what's the difference between vugs and geodes? :0!!

Geology of Gems & Minerals Oh wow! Thanks for explaining that! Rocks, crystals and gems are so fascinating!😍
And that cave was rather deep under ground too, not like you could get scared and just turn around and run out. ha ha ha.
I understood every single thing , I have to make a ppt on this and I am sure everyone will love my ppt in school
I found this very fascinating
RUclips have the sweetest teachers ... 🌷😘

I already saw one..in the mall with a purple shiny stones inside..its really beautiful😊
The purple gems inside is amethyst and rarer than the normal white and clear geodes

Once I saw a piece of pure raw iron, that’s when my rock fanatic mind started to kick in.
This is so great. Quality of this one is top notch.

Any recommendations for purchasing good quality geods?
While I did not quite get everything in the video, I really liked it.

Thanks. Now I don't have to write this comment. I figure she meant that calcium based crystals are more likely in sedimentary geodes.
Very well done..Thanks
Agate geodes are my favorite. But they can't be found here in the U.S. as far as I know
I love the Geode area rugs by Safavieh I saw at Lowe's The designs are so beautiful and unique. Getting an 8×10 rug for the living room.

lol for drNozman (i'm french and when i saw his background I was like :wait rewind that a bit)

Why do they spark when you hit then with steel?
Hi Nethan! It has everything to do with the pyrophoricity of iron. Iron combines with oxygen very quickly and generates heat when it does so. Rust happens slow enough and over a large enough surface area that the heat is negligible. However, if tiny particles of iron with a larger relative surface area to their mass are exposed to oxygen, they oxidize very quickly and cause enough heat to ignite flammable materials such as tinder or gas. The quartz or flint is used because it is harder than steel and can scrape particles of iron off of the larger mass fine enough to ignite.
