Pepe's, or pele's? I'm afraid people called José (nicknamed Pepe in Spanish, after p. p., standing for pater putatibus, Latin for foster father, the role of St. Joseph in Christian mythology) have nothing to do with this mineral.
This stuff is extremely sharp and dangerous! ONLY approach with protective equpment, starting with GOGGLES and RESPIRATOR. You do NOT want this stuff in your eyes or lungs! When it shatters, it can fling tiny to microscopic fragments everywhere, and silicosis is no joke. You will also probably want tough gloves, and thick, tough clothing you can either wash or throw away afterward.
The shattering effect is the same as what happens with molten glass drops in water called Prince Ruperts drop. The entirety of the strand literally shatters at any break due to the internal stresses solidified within the strand. It’s also spectacularly resistant to compressive forces such as breaking with a hammer but a simple snap of the strand and the forces holding all the stress in place releases all at once shattering into a thousand pieces.

@@jonathoningles2703 Isn't sand just broken down rock. You can make sand with glass too. I believe that once it breaks down it just turns to dust, but I guess it would still be bad if it got in your lungs or eyes afterwards.
Interesting! I live around those obsidian volcanoes you discussed and have heard lots of geology lectures, but nobody's ever mentioned Pele's Hair. You really do learn something new every single day! 🤯
I found some Pele's hair once while hiking Kīlauea Iki, but it was just a few strands glinting in the sunlight as the wind shifted. I'll have to go looking for those great mats of it in Kaʻu sometime, that's pretty incredible!
Of course, the mats shown were post 2018, when it covered the parking lot in 2-4 inches of material. Might have blown elsewhere since then. Just ask / email USGS the best spot to find chunks of Pele’s hair for photography. They can be quite helpful.
Another unusual form that I came across during my 2008 holiday in Iceland is something they called Pele's Tears. As you can guess from the name, they are small droplets of black volcanic glass. The pair of Pele's Tears I got had been made into drop earrings, which I've paired with pierce work silver earrings I made a few months beforehand. THey make a soft chiming sound when worn together. I wish now I'd bought more examples, but at the time my money was somewhat limited, and I didn't know what else I might find... Oh well, next time...
Im thinking more will be found with Iceland's recent and some future eruptions, more definitly will occur, that area has them goes off in close spurts and for a while. Their maybe more such eruptions elsewhere soon too. Keeping an eye out on Hawaii's kilueaha and definitly Loa statuses too.
I live over the Missoula Glacial Floods deposits. I learned about it from a local friend. Then I watched 100's of hours of lectures by Nick Z and other profs about the subject of this and geology on the whole. You have one of the absolute BEST channels on the internets. The amount of information contained in these rather short videos is intense compared to other content creators that take 65 minutes to get to any real point. My time is so important. I don't know if you think this way it or comes naturally but being concise....that's a gift....a good teacher you are. I'm a flight instructor (back in the day). In many teaching environments there is NO time for being anything but concise. You just keep on exactly like you are. I'll watch these vids form stem to stern.
I've never seen Pele's hair, but here in the Canary Islands there is obsidian near El Teide on Tenerife. Not sure how old it is though. Also after the submarine eruption near El Hierro, the first life that re-appeared was a new bacterium called "Venus's Hair." If Pele's hair ever appears anywhere here, I will remember not to touch. it. Thank you for all these fascinating videos; I am learning a lot.
Although Teide has produced numerous basaltic eruptions, its large caldera has numerous very tall viscous rhyolite lava flows. Those rhyolite flows have some obsidian!
"In Hawaiian religion, Pele (pronounced [ˈpɛlɛ]) is the goddess of volcanoes and fire and the creator of the Hawaiian Islands. Often referred to as "Madame Pele" or "Tūtū Pele" as a sign of respect, she is a well-known deity within Hawaiian mythology and is notable for her contemporary presence and cultural influence as an enduring figure from ancient Hawaii." - Wikipedia
She's also apparently known for being very, VERY easily pissed off. Like, you blink at the woman wrong and she loses her shit. Sounds like my ex, honestly.
They were showing the name in the International Phonetic Alphabet the second time bc it provides an objective pronunciation instead of relying on the readers accent to produce the words in your guide the exact same way you do. (Also pay-lay would be incorrect Hawaiian pronunciation bc the -ay is a diphthong instead of a single solitary vowel sound) Sorry to be obnoxious just that as a linguistics major I found it rude to laugh at someone for using what is literally standard practice
It's very fragile, so I guess you can't find Pele's hair being sedimented in areas of former volcanic eruptions, right? Or is it possible to identify remains of Pele's Hair in old volcanic rocks? Nice video about this fascinating stuff. I guess it's very dangerous, like asbestos, if you accidentally get this into your lungs. 🖐👴
Definitely yes on all of the above. Pretty much any solid particulates cause nasty problems in the lungs and sharp fragments of rock and glass are particularly bad because the immune system can't get rid of them. As for the latter question all kinds of glass are metastable so the right question should be what is the effective half life for them to undergo spontaneous crystallization For obsidian this is on the order of tens of millions of years making intact obsidian older than the Miocene rare. Given that this is a lower silica glass which forms thin strands this should have a much shorter timescale to crystalize.
That was fascinating! I live in Oregon and have hiked to the top of that huge obsidian flow in the Newberry Crater. What an amazing site to behold. It’s such a humongous mountain of obsidian it’s enough to make a rock hound break out in seizures from excitement alone.
I love Pele's hair and have seen the golden strands, even if it was a long time ago. I was surprised to know that Pele's hair can also be seen at other volcanoes in other countries, but you learn something new everyday. I took a photo of Pele's hair, but the picture came out too blurry because this was the time when people used film instead of digital cameras. Can you do a video about Pele's seaweed and Pele's tears in a future video? I do not think that I have heard of her seaweed before and I would like to learn more about it.

Fascinating! I'd never heard of Pele's hair before. Not surprising though that it shatters into tiny fragments, since it apparently formed under a jolly old lot of stress.
I like learning geology. I never heard of Pele's Hair before. It is good to learn something new and interesting everyday, today, this was my new and most interesting thing. Thanks for the vid.
I used to catch our drinking water off the roof and I remember sweeping several large shopping bags full of Pele's hair off the roof after the 83 eruption . I designed our water filtration in several steps to keep that shit out of our livers. Still alive in 2022.
I was looking at some lava flows last week that clearly had iron in it. How the heck does that work if anyone wants to answer? Does it just oxidize when it gets exposed? I was under the impression that lava was iron poor.
? Huh where did you get the idea lava is iron poor? Volcanoes are the main source for replenishment of Earth's mineral cycling. Now notably the iron content does vary with more silica rich crystal fractionalized magmas tending to contain far less iron but iron is quite frankly everywhere in the universe for the same reason it causes stars to effectively "die" namely it has the strongest binding energy per nucleon of any atom which can be produced by stellar nucleosynthesis. As for what happens when it does get exposed to air yep it does indeed oxidize which can be a useful means to gauge how old a lava flow is if more precise methods of dating aren't available. Note that it isn't just molecular oxygen which reacts this way however as iron and other metals in volcanic rocks such as calcium manganese react readily with carbon dioxide as well as water which plays an important role in Earth's natural carbon cycle. For example the iron in olivine can react with O2 to form magnetite. Sure Earth's crust is highly depleted in iron compared to is cosmic abundance but that doesn't mean iron is scarce since cosmically Iron is literally everywhere being the 9th most abundant element in the observable Universe and as iron has a strong chemical affinity for oxygen the 3rd most abundant element in the Universe this means that where oxygen exists some iron will too.
Its debatable in the case of glass as to be a liquid generally the definition used says that flow has to be demonstrated at some long timescales and this has not been observed in any kind of glass both natural or man made. Thus its typically referred to as an amorphous solid. Note we can't rule out the possibility of glass flowing on timescales beyond 480 million years but even if it does this is far longer than the typical timescale for spontaneous crystallization of obsidian which has an effective half life on the order of tens of millions of years. Thus far glass has never been observed to flow and the geological record for natural glass indicates that if some effective flow rate does exist it must be much longer than the timescale for spontaneous crystallization by over a full order of magnitude. My crude back of envelope calculation says around 24 times longer likely far more as I used a very generous upper limit on the effective half life for crystallization. That is to say if glass does flow it thermodynamically isn't stable enough to last long enough to ever do so.
Was going to ask about the seaweed and the tears but the fact that you mentioned them properly means that you plan on doing something on it in the near future
amazing to find out where these structures in crystals actually come from, this was mind blowing (for me) I have many crystals and have specimens such as obsidian and kunzite quartz which contain this structure known as Peles Hair, yet in the meta physical world known as angel hair inclusions. I have a very rare pice of pink kunzite which contains this inclusion, could I ask is it rare for Volcanoes to produce other materials such as Kunzite, or is this as common as a basalt volcano producing all the differing types of obsidian, such as green obsidian and silver sheen obsidian golden sheen obsidian, and in addition is golden sheen obsidian a mix between black obsidian and Peles hair. Thank you. Alaya Uk.
Hmm note what you are talking about is a bit different from what this video is focusing on. The minerals you describe form in pegmatites which are an igneous process of turbulent fluid separation and crystallization that occurs in evolved magmatic fluid injections. The reason such features can form there is similar however in that the process occurs extremely quickly on the order of hours to days meaning the minerals that precipitate out never establish local thermodynamic equilibrium states allowing large inclusions of incompatible elements to persist. Its hard to imagine but studies of even huge meter sized pegmatite crystals show that they form on timescales of a few days or less!
Most likely to be the mineral Rutile enclosed inside the crystal of Kunzite which is the pink variety of the mineral Spodumene. This is a mineral that forms in pegmatites and is not of volcanic origin.
@@paulcragg1315 thank you for your kind message, I’m new to this side of things but really was interested in how that peles hair evolves over time. Thanks for letting me know. Warmly Alaya.uk.
@@icollectstories5702 thank you, does it stay in the air, or does it disappear after time passes, does it somehow float away, or disintegrate? Thank you in advance.
I am a student in geology sciences and i have been given a different explanation for obsidienne. According to my teachers it form when magma rich in some elements that prevent cristal formation cools because when magma cools really fast, we have like regular volcanic rocks with very small Cristals. And it makes sense to me
I made the mistake of putting my backpack down on the ground while visiting Kiluea. I didn't realize that it had collected pele's hair on it and put it back on. I ended up getting thousands of little pokes and had to suffer till I got back to the car. The backpack had to be scrubbed with a stiff brush before I could wear it again.
Requested topic: geology of the other terrestrial planets in the Solar System! It would be fascinating for you to cover the different rock types and differences between the geology of Earth and Mercury, Mars or the Moon. Doesn't have to be a frequent thing, just one video here and there between Earth-related videos.
This guy's got a bizarre speech pattern. "This is Pele's hairrrrrr" "hard to remove from the skinnnnn" "from separate locationnnns" "long strands of materiallllll"
WOW, what are the things called Apache tears I had some glass stones and someone say they're called Apache tear's. So what are they really some are blue and green.
You know, I never made the connection until browsing the Wikipedia article on Pele's Tears, but they bear a superficial similarity to a Prince Rupert's Drop, and Pele's hair would be analogous to the tail.
Pepe’s hair is such a beautiful and unique variety of volcanic glass! However, unlike obsidian it is quite brittle.
it is very pretty.
How does red obsidian form? Better question...where can it be found?

Yes its quite dangerous to touch or inhale. It can also get in your eyes which can be really really bad

omg thanks learnt something new😉Peles hair and do not touch...churr for share💯👍🏻
Natural fiberglass insulation, wild
Basically natures own spicy cotton candy
1:27, this is awesome but what about 70% Silicon Dioxide and 14% Sodium Dioxide?
Excellent!
A fountain of airborne fiberglass!
One more phobia...
That was very interesting! Thanks for the video :o)
Just beautiful. Do I get points for guessing what it was immediately?
OMG Skyrim has this everywhere!
I am a student in geology sciences and i have been given a different explanation for obsidienne. According to my teachers it form when magma rich in some elements that prevent cristal formation cools because when magma cools really fast, we have like regular volcanic rocks with very small Cristals. And it makes sense to me
1:20 Great snowmobiling in that area, if it even still snows there. Not been there in 20 years.
Natures fiberglass, nuff said.
I made the mistake of putting my backpack down on the ground while visiting Kiluea. I didn't realize that it had collected pele's hair on it and put it back on. I ended up getting thousands of little pokes and had to suffer till I got back to the car. The backpack had to be scrubbed with a stiff brush before I could wear it again.
Imagine falling onto it, it be hell X.x
So it's natural rock wool. Neat.
I remember Pele having slightly different hair.
Requested topic: geology of the other terrestrial planets in the Solar System!
It would be fascinating for you to cover the different rock types and differences between the geology of Earth and Mercury, Mars or the Moon. Doesn't have to be a frequent thing, just one video here and there between Earth-related videos.
I have a lot of cats, so I’m used to hair everywhere,,, but that stuff is weird.
This guy's got a bizarre speech pattern.
"This is Pele's hairrrrrr" "hard to remove from the skinnnnn" "from separate locationnnns" "long strands of materiallllll"
Makes me think of angel hair quartz aka rutile quartz. Very pretty!
ahh, so that's why alolan diglett and dugtrio have luscious golden locks..
Is it possible that the strands within rutilated quartz are indeed variations of Peles hair?
Thank you
Pele's fiber optic cable.
beautiful
Oh, it is sooooo pretty!
WOW, what are the things called Apache tears I had some glass stones and someone say they're called Apache tear's. So what are they really some are blue and green.
Volcanic cotton candy!!
From what you're describing, Pele's Hair is like fibreglass
So, I need to go to Oregon to mine the Dragonglass? Useful, considering the undead in Portland.
Cool, hope some videogame developer could make a new type of volcanic biome.

You know, I never made the connection until browsing the Wikipedia article on Pele's Tears, but they bear a superficial similarity to a Prince Rupert's Drop, and Pele's hair would be analogous to the tail.
In Iceland it's not Pele's hair though. It's Ymir's beard.
huh... a nice environment setting for fantasy/sci-fi games... havent seen any rock/silica grass before in any games...
Super neato! 👍
