Oldoinyo Lengai Volcano - Amazing Eruptions of Silvery Carbonatite Lava
ฝัง

- Oldoinyo Lengai Volcano (Tanzania) is the only volcano erupting silvery Carbonatite lava in historical times. Unlike normal lava, this lava looks like a silvery mud as it is too cool (550-700 deg. celsius) to glow visibly during daylight. A very weak glow can be observed at night and captured by long exposure photography (see e.g. www.photovolcan...)
Currently the type of activity shown can not be viewed following larger eruptions in 2007-2008 which left a large crater and removed the small eruptive cones as seen in the footage. The footage taken in July 2000 shows an extremely active cone on the main crater floor. A brief view is taken into the tiny lava lake in the top of the cone during a phase of reduced activity and multiple overflows and resulting lava flows and other features are documented.

I checked the elemental analysis of this lava, and it is highly enriched in rare earth elements. Carbonatites are one of the rare rock types we search for due to the levels of REEs in them. In addition to elevated REEs, this lava also contains very high niobium, barium, strontium, and zirconium!
Thank you for your great content I especially appreciate the videos on New Zealand Volcanoes.
The city I live in Dunedin is in an extinct largely eroded shield volcano. I cannot find a whole lot of information on it though documentation seems very scarce.
high REEEEE levels?
Hi!
People who have stepped in it have ended up with third degree burns to their feet... It is potentially fatal if enough of your body gets in contact with it...
What temperature is it?
@@fpsdovah2572 500-600 C while erupting.
I mean the fact that anyone can even survive purposely stepping into lava is pretty impressive
The fact that they actually touched it still amazes me
This volcano is so weird! I love it! I am a major geology nerd, so learning about this volcano is fascinating! Yes, people, that is lava, it's not mud, oil, tar, or water filled with ashes and dust. It's the ONLY volcano in the entire world that spews this type of lava, which is probably why most people have never heard of it!
Honestly, I am utterly shocked that this volcano isn't one of the 9 wonders of the world! It deserves it big time because of the lava.
I see that volcano ate at Taco Bell last night as well...
It looks almost as if you could touch it. But woe to you if you do.
It's still lava but half as hot as the orange one
Although the melting point is near 500, the temperature at which it is erupted is often higher, allowing it to flow quite far before cooling to the point that it solidifies..
The crackling noise is mainly because gases escaping from the ground under the lava flows are making bubbles in them..
1. Not my foot, 2. Leather walking boot the other guy was wearing is good protection if just briefly touch lava..
it kinda looks like a crappy 1950's special effects volcano
Cue the Iguanas and Chameleons; slow the projector down...
Oddly satisfying lava... It looks like a natural oil well
Alexander HD Videos just don't touch it xd
America would love to invade I bet lololol
1:39 I never thought I would see arterial spray from a volcano
I climbed Lengai in 2006, before the exciting events (a massive effusive eruption followed by an explosive eruption that built a new cone) in 2007-08. I do hear that the new cinder cone is slowly filling up with lava once again, so eventually flowing natrocarbonatite will be accessible to those who dare to climb Lengai. Give it 10-15 years I'd say. I highly recommend going there, once the lava flows can be viewed from close-up again. It's a hell of a trek - just getting to Engare Sero, the village at the base of the mountain, is a bit of an ordeal, requiring an off-road (4WD) vehicle, an experienced off-road driver, AND someone who can fix the vehicle when it breaks (because it will; we had a large group that took 3 vehicles to the village, *and they ALL broke down,* requiring actual TOWING with a tow-strap - the radiator got cracked on one, causing it to lose considerable fluid whenever the driver eased off the accelerator, another had a part of the exhaust system *fall off* ...I can't remember what happened to the third one). Actually, now I think about it, getting there is the hardest part (since there is a 30 km stretch of land where there is literally NO ROAD). The climb is (or WAS) easy by comparison. It took 4-6 hours at the time (but I think even someone who's REALLY out of shape could've done it in 8), basically just hiking uphill. Nowadays, I've heard it's gotten a bit harder. Hire a guide and porters if you go - that's how the Maasai people living in Engare Sero make their money, and they're great at their job (making your job - climbing the mountain - that much easier). Doing all of this requires an adventurous spirit, and a willingness to suffer. But it's worth it.
If you go, just remember that while it may be wildly awesome to see, it's also dangerous as hell. Aside from the volcanic hazards (which are fairly substantial), and the wild animals (deadly venomous puff adders and spitting cobras, plus leopards and scorpions have all been seen in the summit craters by tourists visiting the volcano), the weather can be quite volatile as well. *We weathered not one but TWO massive thunderstorms when camping the night in the crater - I've never been on a tall mountain in a thunderstorm before (or since), and it was terrifying.* They lasted for about 45 minutes each (with barely 10 minutes between them), and the clouds were less than a kilometer above our heads (I know because I took a long exposure photo about 5 minutes before the first storm started, and the lightning illuminated the clouds, showing how low they were). And once it started, lightning was striking the hornitos, and the ridge just above us that separated the north and south craters, at an alarming frequency - a flash every 1-2 seconds (though most of the flashes were cloud-to-cloud). The wind was VERY powerful too (a conservative estimate is 80 km/h gusting to ~120...but I think it might've been even stronger than that sometimes) - it stove in a couple peoples' tents (breaking their tentpoles)...I've never been so glad to have my guy lines out and properly secured (or to have aluminum tent poles, which are more resilient than the standard fiberglass). But even with the right equipment for the situation, my tent was still significantly deforming, and I had to hold my hand up against the nylon (pushing it out against the wind) to prevent it from being over-stressed. Oh, and in addition to the storm, there were loud booming sounds coming literally from beneath our tents, in the interior of the volcano (every 30 minutes to an hour we'd hear a boom) - it was VERY active that night, though conditions precluded us from witnessing any of the eruptions. Also...not even 2 months later, our campsite was covered in 10 feet of lava. So yeah...dangerous place. But UNFORGETTABLE.
I still have some samples of a lava flow I witnessed erupting (alas not taken from active lava, but from the flow once it cooled). It's no longer nyererite and gregoryite - the moisture in the air reacts with these minerals, creating pseudonyererite and pseudogregoryite - but the crystal shapes are still the same as they were when erupted, and they look pretty similar.
Thanks for sharing. Cool story!
@@ronconnor2694 If you're interested, I have a video on my original TH-cam account, which shows one of the eruptions. Be warned - it was, as they say, filmed on a potato (heh...my camera was pretty good for 2006 but this was well before most cameras had decent video capability, and camera phones were in their infancy as well), so the quality is no bueno...best viewed with a smaller browser window (as even TH-cam back then displayed videos in a smaller frame, by necessity). I also think it was the first video I'd ever uploaded to TH-cam, so it got no editing...just directly uploaded from my memory card.
Still, it's pretty cool. My incredulity is palpable...I'd been standing on this volcano for several hours, and it had been doing literally nothing at all (visibly anyway), and all of a sudden, one of the hornitos eroded through, and a lava pool that had built up within was rapidly draining out in front of our eyes. To say we were lucky to witness this isn't doing the true rarity of the situation justice.

Ol Doinyo Lengai is probably the coolest volcano on Earth, and I mean that in both ways :P
Mud
@@Josh-lq7lz No, this is not "mud".
I think a medic would need to explain response to strong pain. Dont think body would distinguish between 500 or 1200 degrees as both are so far above tolerable range that pain receptors will be fully triggered by both (TRPV receptors trigger at above 43 and 50'C (according to quick internet search)). Heat would however soon destroy the receptors. Also, extreme pain may apparently cause unconsciousness or dissociative shutdown of pain perception.
the lavas from this volcano have both the lowest eruption temperatures (down to about about 500 degrees celcius) and the lowest viscosities of any known terrestrial lava. Amazing
This is oddly effective at inducing sleep in a caffeine-addicted college student :D
That's really cool! First time I ever heard of that.
Mario World Chocolate Island
I'm willing to bet more tourists get hurt by this. "Oh it's not lava, it's just mud! Lava glows red. Hurr hurr I'mma touch itOHGODWHYISMYHANDMELTING"
Looks like my behind after taco night
sounds like an egg frying. amazing stuff though. i never knew there was this kind of lava.
Welp, now I have to pee.
No, "normal" basaltic lava has temp. of about 1200 degrees celsius...
It is the only volcano with that type of eruption.
People look at this an think its just like mudpots and boiling springs of Yellowstone....It is not. The features you see at Yellowstone are hydrothermal, or heated ground water. This lava is molten rock like all lavas......it is just a different kind of rock that melts at low temperature.
It has a temperature of around 500 C and you can see it glowing red hot at night. It is still lava, even if it looks like mud.
Looks cold
If I wasn't referred here by a news article about it, I would have figured this for a natural tar pit being boiled or something. Strange stuff.
Yup, this is the only known volcano that does this, I just looked it up.
imagine if someone touch this thinking its natural oil and they didn't know it was lava because its black
Wow!!! fascinating I was just reading an article on livescience that has this video posted. Mother Earth and Nature is truly awesome.
is also faster than normal lava.
Now I want some bacon.
So weird but amazing
That is amazing.
Amazing and beautiful!
What is the temperature of this lava?
It doesn't look too hot. Beautiful video, thanks.
its not very hot, its very unique in that it is rich in sodium carbonate... only around 500C
The description says 550 to 700 degrees Celsius, which works out to about 1020 to 1290 degrees Fahrenheit.
dragonridley That sounds pretty hot to me. What do you say, +Dmh Frou?
hudson steele It's very hot, and a beautiful phenomenon. The lava looks like mud, that's why I thought it was not very hot, at first.
Dmh Frou I wasn't trying to be condescending, really, but I noticed the ground bubbling at 0:40. Check it out. By the way, it certainly IS beautiful. God's hand at work. I had never seen this kind of lava before.
Fascinating! Saw it 1st on the Weather Channel.
This is really interesting and cool! That lava looks a combo of chocolate milk and coffee!
+returnofsoma Mmm...I wish there really was a volcano that spewed molten chocolate!
HipHopOtaku would you really want molten chocolate? think of how it would burn your face off D:
Mother nature's road repair kit
02:23 made me blush
that is natrocarbonatite
I’ve never seen a video of this lava before, and it really is just as bizarre as everyone says…
this is how your chocolate bar is made, son. Pay attention now.
Really unique! It's weird and beaty at the same time! 😍🌋😋
Video très satisfaisante à faire en asmr
Thanks for the video! 😃
How do you know it isn't a hot fudge volcano?
why u guys so close what if some droplets touched you!!
Usa be like THATS OIL ON THAT MOUNTAIN TAKE IT NOWW!!!!!!!
MEANWHILE...
SOLDIER : THATS CARBONITE LAVA NOT OIL
i hope Col. Stryker doesnt find this, or Wolverine is gona get really heavy
So where on Earth is this?
If it really is that hot, it would be pretty dangerous there. It looks calm but that volcano could just blurt out a shower of material any time. I don't think the photographer would enjoy a 500 degree shower.
sounds like a wet fire
Anyone else thinking of Bacon?
Not if you use Med-x
THE BLACK LAVA SOUNDS LIKE WATER POURING DOWN FROM THE SKY
Me too.
thats so cool for lava LOL :)
This looks so cool :D
One of my most favorite volcanoes. I hope I get to see it in person one day
Today June 19, 2018 on the big island of Hawaii the famous Kilauea volcano Fissure # 18 that has been spitting out huge amounts of orange, yellow and blood red lava for many days creating a lava river to the ocean, TuTu Pele brought forth "Carbonatite" a silver lava to add to her collection of colors for the new land she is creating. Check historical records. One might have been broken today.
I came from a video about what is The Real life version of minecraft "stone " and ı think its really looks like carbonatite
Looks more like tar or oil than lava
Wow, it looks like oil. It doesn’t look hot at all.
I googled this because of Imgur.
explain why you saw it crackling on the ground and you can see the heat waves coming from it,,
but on the other hand falling in lava would not hurt. since your nerves are being seared.
Looks like Adamantium. Sounds like pop rocks
like a soda
If you dropped your keys in there you might actually have a shot.
This actually looks like coca cola up until it flows for a bit and becomes this thicker black stuff
This was really amazing. Aren't there poisonous gasses and stuff? Wasn't it hot? How can you be brave enough to be that close to it!?
Kind of sounds like someone cooking bacon
t1000
Cursed chocolate!
Yeah lemme just stick my foot right next to boiling black lava.
Ace King it’s not boiling. It’s actually extremely cold. The only volcano in the world that has black lava and the only volcano that is super super cold
Extremely cold by lava standards, but 500-600°C is still hot enough to boil water five times over.
Now that is strange stuff.

It's the morning after Taco Bell
k i am not sure i am supposed to say that but i am not GREAT at these volcano stuff... is that petrolium?
Its molten rock, just not the usual molten rock. Limestone and such.
*w a t a lava intensifies*
I wanna believe its lava but its so runny it looks like oil
That Volcano gotta stop taking a long ass piss and lay off the tacos.
When you open the soda right out of the vending machine
I see I'm not the only one who came to this conclusion.
incroyable lava i've never seen like this before not after this moment loool
but i really like it and really want to go and watch it by my self and touch it with a spoon hahahahhahahahahaa like they did
Samah Sa ure welcome
if you look closely, you can see Han Solo signature
just a question ? thats is burning lava? or just mud?
yes its cold lava, but DONT TOUCH IT!!!!! ITS STILL HOT
Makes you want to touch it !
now I have to shit
@Photovolcanica I read in a book about volcano's several years ago and I found out about a unique volcano that erupted cold lava of different color and it was the only known volcano that did it. Is this that volcano that that I might have read about?
Maybe. There's another weird volcano which erupts pure sulfur, too.
It’s less viscous than water
that looks so cool
What a funny and beautiful little volcano
1:23 looks like a shaken soda opening up
it looks like shit when dried up
Infact the volcano is rare
It looks like an episode of dr pimple popper
cool
On the most volcanically active place in the solar system, the moon io, this kind of silicate lava is present in massive lakes 75km across, its amazing
