ITT post badass-looking rocks

I like white, matte rocks. But I can't remember the name of them.

ooooh, I get it.

>posts a mineral

Idk about you, but when I see her, my dick is rock hard

that looks like a langolier

Geologist's wet dreams.

Earth Porn.

Make a Geologist Dick Rock Hard.

>that looks like a langolier.

Stephen King's The Langoliers !!!

is that a sith holocron?

>Pallasite
Is That the Minecraft Glow Stone ?!

>banned in 30 states
>contains chemicals known to the state of california to cause cancer

This is a Japanese rock.

yes

>HHHAAAHAHAHAHHAAA

what's the name idiot?
I used to collect rocks when I was younger

pebbles allowed?

I don't know I just googled "badass rocks" and this came up lol

fuck I don't know why some are turned

this one's a slice from the canyon diablo

...

that's not a natural occurence

I found that shit in my backyard when I was 12, but I touched it and it gave me autism.

cuz they TURNT ;^)

nice hair dude

wow really

Any geologists here who get sexually aroused by beautiful rocks?

pretty hard

I can only get off by rubbing rough rocks on my cock.

did you really though licking them had any kind actual usage?

Hello, rock nerds.

I want to ask, are there minerals that glow in the dark?
Note, not under special UV light, but rather in a more natural occurring "dark", like a basement, a mine, and so on.
Is such a thing possible? To have a mineral that makes sense, which seemingly creates light humans can use to see things, but doesn't kill humans by doing so.

I am writing something and want it to make sense.

I think a phosphorescent cristal wouldn't be technically impossible, but it would require to be exposed to light beforehand.

Other than that you could imagine a cristal that, when exposed to air would react and produce light, but from what I know chemiluminescence happens mostly in organic compounds.
depends on the level of realism you want to involve in your writing.

just after posting, I realized I was dumb and that the most common case of chemiluminescence is actually a mineral, white phosphorus.
But it doesn't really sound like what you're looking for.

I am after the following scenario: people walk down a cave, they find glowing rocks, and use them as makeshift flashlights. Of course I don't mean a bright stream of light, rather something you dangle close to what you are trying to see, like people do with phone screens today

Although a rock that you can "store light" in also could be utilized in another scenario.

How long does Phosphorus effectively glow? A fist sized rock wouldn't just burn out in days, I imagine?
Also, is it a dangerous, unstable thing? When I read White Phosphorus, I think of war movies and an explosive named that way.

>phosphorescent cristal wouldn't be technically impossible, but it would require to be exposed to light beforehand.

What if it's a phosphorescent crystal with triboluminescence properties? You break the soft stone in half and the initial spark causes the phosphorescent mineral to glow for half an hour. When the light runs out you split the stone again causing another spark and 30 more minutes of glowing. And if you throw the stone to the ground it'll make a bright flash like a flash bang grenade. I know triboluminescence isn't that strong in real life, but this is a book. Creative liberties are allowed.

phosphorecence ain't magic. it doesn't create light, itkinda "stores" it, so if small fraction of the initial spark it managed to capture is strong enough to shine half an hour, the spark was also probably able to turn your eyes into shish-kebab.
And triboluminescence is pretty weak.

white phosphorus glows low green when exposed to the oxygen of air, and that last until there is no phophorus anymore (it's a chemical reaction). I couldn't however gave you an estimate of how long a certain mass would last, but I guess it could work the way you want it.

However, it has a slight tendency to self-ignite when exposed to oxygen, and, when burning, glow with a distinct shade of "my eyes! I'm blind! Why, AAAAH, why?". So yeah, not stable for long, so that would be possible only if the cave was sealed shut and with an anoxic atmosphere and just recently opened, which is not so unlikely given the good circumstances.
And btw, your guys shouldn't hold it directly. That is, unless you want somebody to lose a hand, in which case it's a good way to do it.

no

I need help, any knows for sure if emeralds are vulnerable to solvent, like toluene, if I leave some emeralds submerged in toluene, will i damage them???

>laughs geologically

cocaine

crystalline or massive?

my guess is achieving translucence, luminescence, and phosphorescence into a singular crystal structure would be insanely difficult

>dietary minerals REEEEEEEEEEE

Lets say you put a radioactive mineral next to a fluorescent one. Would natural radioactivity be enough to trigger fluorescence?

Reminds me of that artstyle indie games are coming out with recently

This is probably the best thread on Veeky Forums right now

Crystals/Materials/Chemicals that glow with radiation are called Scintillators.
en.m.wikipedia.org/wiki/Scintillator

Such as Crystals of NaI(Tl) (sodium iodide doped with thallium).

lel good story

>the rock laughed
>we killed the rock
>good times

JESUS FUCKING CHRIST

THEY'RE NOT ROCKS YOU FUCKING FAGGOTS

THEY ARE MINERALS!

>Terlingua Calcite
You have to use ultraviolet light
With this parameter every uranium(even these secondary) and thorium minerals fluorescent

I think not, silicates dont really dissolve in Organic solvents

aayo what is this motherfucker

this a fuckin meteor or what

found it in my driveway. gotta know if I need to dig around for more meteors

I think it looks like rock that's millions of years old

looks like metal banding in that motherfucker. probably a meteor.

you sayin its a meteor? meteors are millions of years old nigga

check out that fuckin rust. what is this shit?

Paleofag's Simple Guide To Telling If A Rock Is A Meteor
1. No, it is not a meteor.
Questionably Extraterrestrial Doodad

nobody has any idea about what this is? did I just invent a new type of rock?

...

dude I'm a paleofag, not a geochemist. all I can say for certain is it's neither sedimentary nor particularly felsic, and has been moderately weathered by transport. if I had to guess I'd say it's a lump of andesite.

Those columnar rocks were actually rocks, stop spamming posts with this faggotry

>andesite
sounds believable

might be eclogite
look in to geological map

This is Pebblephila.

Thanks for contributing. I'm in Wisconsin, and due to the glaciers this stuff could be from anywhere. I'll keep investigating though. Thanks again.

Cool, glacial till then.

Yes I'm rock hard right now

My little slice of Muonionalusta meteorite with Widmanstätten patterns. Literally from a planetoid in the protoplanetary nebula around the same time Earth was forming.

It's a slice through a metallic meteorite. Yellow bits are olivine crystals.
