#Geode
We gave our kids a couple of small geodes for Christmas. They just cracked them open and were amazed. Thanks for making this video to help explain!
Who all came here after seeing amethyst geode opening video
Me
👋
Me! 🤣
Lmfao me 😂
Me I thought the chain was going to break
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!
me too! but she isn’t the fortunate one. boo-hoo!
When youtube teaches you more than science class....😂😂
Dreambeam I know right
I don’t know why teachers think it bad.....
PrincessUni965 YT I know! I had a test in biology and the first part was seed germination. Like a WHOLE page! How will that help? Can't we learn about gems instead of gas exchange? Nope I have to learn off the "useless time-wasting" website :/
Dreambeam yup
@Seth Ellison that's exactly right. That's why we should become communist, becuase you can't be a slave if you've already starved to death.
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...
That's incredible! Glad we could help re-spark your interest/love for geology!
I'm not a geode yet, but I àm full of hot air.
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!
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!!
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.
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.
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.
Wish I had a gemstone collection but my video game and book obsession doesn't come cheap. They are all stunning though.
same XD
this is going to help me with my science project and the science fair
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.
I understood every single thing , I have to make a ppt on this and I am sure everyone will love my ppt in school
Great explanation!!!! Brilliant video!!!! Thank you!!!
Thank you!!
Just stumbled onto and subbed to your channel.
Amazing natural beauty every frame of this video! 😍 Cracked a first geode this year!
Cool stuff, I always wonderd how amethyst was made, thanks for sharing your knowledge, keep rockin on.😎👍
I know all about gems. I just watched a 4 minute and 46 second video that was hosted by one. 8-)
And coin collecting. Learned it from a fine dime.

I found this very fascinating
Best info. ever! Great job!👏👏👏👏👏👏👏👏👏
While I did not quite get everything in the video, I really liked it.
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 should I enter my "be gneiss" joke here, or above?
MsButterFlySting80 I don't understand how this relates to my comment.
Geology of Gems & Minerals oh nothing really, it's the name of a formation I learned from some other TH-cam 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!
No offense taken just wasn't sure what you meant in the context. :-) I am familiar with the pun.
Thanks. Now I don't have to write this comment. I figure she meant that calcium based crystals are more likely in sedimentary geodes.
I wish my teachers were like her
This is good for my project
This is so great. Quality of this one is top notch.
Thank you!!
Great vid but at times the music was kinda loud I couldn't hear everything you said
Earth is so fascinating
It’s 3am and I don’t know I ended up watching videos about geodes for over an hour.
Her top fits perfectly.
Its just a video about rocks dude come on
You are a goofball 😉 and informed and articulate. And a goofball 😀 love it! Thanks
Thanks but I can't remember anything you said.... was just looking at the beauty of you!!!

the singing part was so cute
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
@@hoskinmage thunder eggs look sweet.. wanted to make a video pretending to make one crack out of an egg..
There are 2 very rare gems in the video 8 , I have only focus on them 2 gems
Can you please turn the music up?
I have a huge glacial erratic boulder in my yard. Is there anything inside it?
Please make a video on alexandrite Or blue amber Or Maybe calcopyrite Plz ^-^
My geode has both agate and amethyst
Wow! That is cool.
I actually dug up an amythest geod once
Please get rid of the background noise. Thank you
I loved the raspberry Beret skit more than you could ever know
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
alternative title: How mini-kindergartens are formed
It' fascinating!!
I find geodes all the time in my backyard but they seem to show up in the mud everywhere we dig. Not in the rock layers.The erosion brings them out to the creek. Like they never saw a volcano around here. In Missouri.
When I was 7, I cracked open a rock and found a geode, but....I didn't know you could sell them and get at least $100(it was big)
What about that good ol' Rutile?
Wooow that is the most beautiful thing i've ever seen 😍😍😍
GEODUDES OMG OMG I LEARNED MORE IN POKEMON THAN I DID IN SCIENCE
And now, these are in Minecraft.
You didn't address the formation of Keokuk Geodes.
I found a rock that didn't seem like a geode because the whole inside was grown solid but when I smacked it open with a hammer all this shiny citrine came out what would it have been
I have a question. Where do the rocks come from?
Lava/magma
I wonder what stones are found in the core of the earth
I misread the title and was expecting to see a video of how a particular Pokemon was made.
They're minerals, Marie.
in iraq i found a geode the size of a basket ball, i spent several hours trying to break it open without shooting it, or doing something that would draw attention to what i was doing. i could lift it and hold it with one hand, it was about 30 pounds, still don't know what was in it.
You should see if some one can cut it in half for you, with a saw. Then polish the cut ends, if it is that type of geode.
@@kfl611 it is still out there in the desert, it is near Arar, Saudi Arabia, that whole area is rich with geodes
@@dysfunctional_vet I always thought geodes were like a piece of magic. So ugly and plane on the outside and so beautiful and magical on the inside.
SMASSHING IS MY THINGGGG

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.
@@gems Ooooh so it has nothing to do with the geod and is just because of steel in the tool. Cool, thank you!
I find quartz everywhere
i hope that not on other peoples hands 😏
I love her beautiful jet black hair
cool

I have a mine in my yard and I found a tiny geode
I have lots of geodes.

A geode indeed began my love affair with all things shiny when I was a little kid. My mom would pronounce it "gourd"; not "jee-ode." It wasn't until I was in a high school geology class that I learned the proper pronunciation. Awkward!
Falena Luna mine was actually panning for gold as a 10 year old and actually finding a small nugget XD. Dam I love shiny things...
You mean minerals Marie !?
So, when a breaking open a geode in Stardew Valley reveals a thunder egg, it’s a lie?
My disappointment is immeasurable and my day is ruined.
I specifically searched for this video because of Stardew valley 😂
Once I saw a piece of pure raw iron, that’s when my rock fanatic mind started to kick in.
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.
Well she might not be a geode. But she's definitely a gem.
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 👍🏽
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.
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.
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
2:55 That was adorable!😍😍👏👏
On a totally different subject ... she is absolutely beautiful in form and face!
Without sounding thirsty, I agree.
Wow she is the most beautiful + maybe like a human geode

lol for drNozman (i'm french and when i saw his background I was like :wait rewind that a bit)
julien jean me too!!
i was formed like a geode. It was really uncomfortable
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.
That is beautiful. Thank you
I want to be a aerialists is that how u spell. It?
Pov your obsessed with pretty stuff watched she-ra,the owl house,amphibia,and the crystal gems and your favorite subject is science:
I don't even watch anything about rocks and somehow watching simplenailogy I got here.
You over exaggerate your acting emotion and body language. Yes. Use it. Cut it back a lil. Like when you say a word at the start of a sentence, words like BIG BECAUSE BENEFACTOR. BENJAMIN. Or P words. You like snap your entire head with your neck. I’m over exaggerating but. Calm down. Maybe sit in a chair whilst talking about geology. Your playing into your own character more than the science your describing. It’s distracting.
Im mad of rocks . I collect very shiny rocks in my house but i dont no if its valuble or not . Soooo sad 😔😔😔
This is so interesting!
Teacher: Today we are going to learn about how geode amethyst are formed.
Kids who played minecraft for 13 years:
This tell you how hard a geode is....
A STONE SLAB BROKE WHEN DROPED ON IT!!!!!!!!!
Is that true? Wow..

*me over here with a mineral that has other mineral stuck together in one in my right hand as i watch*
I found one of these !! huh
