I got my Geology degree from the University of Oklahoma back in 1982. Had the usual field trips; most of which were in southern Oklahoma. Never spent much time on, nor understood what occurred with this event. Thank you for explaining it so well, and what the ramifications were! I love Oklahoma, but my interest in volcanoes makes me spend a lot of time in other places.
I have lived in and studied the geology of the Wichita's for twenty years, and I can tell you it is still active there. That it was tied to a major extinction event does not surprise me. Thanks for the video posting.
My dad used to take K-state students on field trips to the Arbuckle’s. He was a petroleum geologist. I remember hunting rocks and arrow heads and barium sulfate (rose rocks) south of Ardmore. The geology bug never stuck with me as we grew up.
Aren’t there stories of an old volcano in the gulf or that the Gulf of Mexico IS the old volcano? Between E Texas and Louisiana there are cliffs, lakes and swamps that are below sea level? Much like the granite formation he was talking about, Houston maybe lower now after all the new intense infrastructure and more so now with everyone moving there. Lake Pontchartain in French Pont-char- trun (nasal n), in English Pon-cha-trane has areas well below sea level. [ Pronunciation For the word connoisseurs.] It is interesting that from the Great Lakes East of the Mississippi all the way down the Gulf of Mexico, the rock formations or parts of the geologic basement are exposed. Wouldn’t it be fun to talk about this🤓
Something kind of terrifying to think about: Compared to the formation of the Earth, this was only 12-13% ago. On that sort of timescale, we're not really all that far removed from when this happened. At any point, the world could slip into a volcanically active period, and humans could struggle to avoid extinction.
yep these kinds of eruptions seem to occur every 20 to 30 million years on average depending on what size threshold you use and based on similar analysis the last one was either ~30 Ma for large Flood basalt eruptions or 16 Ma if counting the smaller Columbia river Flood basalt group and they have been occurring for billions of years. It isn't a matter of if but a matter of when the next flood basalt occurs. The two best candidate locations as far as I am aware of are either the possible emergent plume responsible for the geologically recent surge of highly alkaline volcanism within the older southern sections of the East African rift zone or the seismic tomographic upwelling anomaly beneath and responsible for the Adirondack uplift dome which appears to be suspiciously similar to what is predicted for a mantle plume head rising up adjacent to a vast subducted slab wall that has already sank down towards the core mantle boundary thought to have represented the subducted slab wall that formed along the Pangaean northwestern margins. It's currently still only reached partway up through the upper mantle if I remember correctly and the Adirondacks started to form around 9 or so million years ago likely as the buoyant anomaly got close enough to the surface for conductive heat transfer from the larger anomaly below to reach the surface so if it is a plume head it will probably take a few million years before it reaches the surface but that would probably fuel a continental flood basalt formation as the area where the basement rocks of ancient Laurentian craton are being thrust into the sky from heat below is huge and seems like it might have something to do with why several ancient fault scars have begun to reactivate but that is mostly speculation
Thank you. I now live about 100 miles south of the Wichita Mtns and had done some reading but that had not mentioned the rifting and volcanic activity events.
That’s interesting, the Wichita’s I loved to explore as a kid and young adult I always wondered why it looked like some of the mountains looked so old they fell over… Thank you for all the content making geology fascinating one day at a time!
Hey...I live in the middle of that! Wichita mountains and stuff. That and being on the edge of the great mid continent ocean is amazing stuff. Lots of old granite around here...including the town of ....Granite.
Have you ever been interested in making a video about Galicia, in Northwest Spain? Geologically very interesting area, a lot of granite and hot springs
Awesome!!! I remember a little while back someone was asking about this particular event from another video that mentioned it in passing. We all went wait, what?? Oklahoma had a flood basalt event???
I've been to the Wichita mountains many times and seen that granite. There are huge boulders of it so weathered that you can peel off the outer skin like an onion.
Did you hear about the hydrothermal explosion at Biscuit Basin in Yellowstone? It jusy happened at 10:19 this morning and so far it seems there was only one video to captire the event. I eagerly look forward to your analysis on it!
USGS talks about it www.nps.gov/yell/learn/news/240723.htm?fbclid=IwZXh0bgNhZW0CMTAAAR0rRnyqLsfnHMRgBFrckITiNCi65LXXFXGwNUVhUeHxkANZSvsETdeGO34_aem_b-9nqZMJXLYXbP4KWix5vQ
Thank you for the information! Love these educational videos, and there's so many places with unexplained landscapes, I am eager for more of these. I do love the Updates too of course, but luckily there's not too many days where we need such updates, meaning people and animals are safer, yes?
USGS has a report www.nps.gov/yell/learn/news/240723.htm?fbclid=IwZXh0bgNhZW0CMTAAAR0rRnyqLsfnHMRgBFrckITiNCi65LXXFXGwNUVhUeHxkANZSvsETdeGO34_aem_b-9nqZMJXLYXbP4KWix5vQ
I want to know some news about the kiluea volcano. Recently I've been noticing that a bunch of earthquakes at a magnitude of 3.0 has been ongoing the past few days at the northern fault line
From Shawn Willsey's video it isn't that unusual beyond that someone was there to catch it on film. When precipitating minerals within those hydrothermal systems form a seal and allow pressure to build up high enough to break through the plug subsequently flashing to steam in the process of depressurization things get explosive. The black diamond hydrothermal pool which was responsible for the explosion wasn't a geyser though which makes sense as for a hydrothermal explosion you need to have a seal formed allowing pressure to reach its breaking point where it can subsequently flash to steam explosively.
Aulacogen, in 45+ years as a geologist, I've never heard anyone pronounce it "ow-la-Co-gen", with the accent on the "co". I believe it's "aw-LOC-o-gen" with accent on the 2nd syllable
This channel has a history of unusual pronunciation, I've never called it out as I've always felt that's a bit rude, but this was a particularly bad example! I've always pronounced it as aw-LACK-o-gen though
I don’t mind if people correct me. But it depends on their motive and attitude as to how or if I will bother with a correction. Bullies or a new fiend makes all the difference. That being said if military brats got hung up on regional lingos in the USA and other English speaking countries we would probably not have the chance to make new friends nor learn a new language wherever we end up. In Turkey we had neighbors.. neighbours from England, that was fun, my name is Lori and their sons made fun. Lorrie = tractor truck S-CHEDU-AL One small example and we spell everything wrong too. I had just turned 6. Oh, and I’m not Protestant or Catholic. Maybe the professor wanted to leave a mark, or that is simply how he was taught. Language is awesome, like finely cut jewel that really catches the light and nearby colours.. colors. This is a fun rant. Thank you for the moment and memories.🖖🏼💛🤍
Didn't know about this volcanic activity, although i have seen examples of the strange flora/fauna (actually they might be something else, ive heard them called just 'biota') of the ediacaran, very strange and primitive soft organisms that disappear around the cambrian explosion
Do you plan on talking a bout the explosion in Yellowstone's Biscuit Basin? Destroyed a boardwalk and shut down that part of the park. Looks like a mini phreatic eruption, but am not sure.
I have a request! Can you look into the Patomskiy Crater? I understand it is a Geological oddity that no one can agree about; what it is made of yes, but its origin, age, etc? no one is certain. Sound interesting?
@@dralord1307 I looked it up. Yes his pronunciation was off, but I still had never heard of it before. As a not-geologist I had always just thought of the Proterozoic Eon as one continuous time period.
@@whiteknightcatThe Proterozoic Eon contains two other geological periods: the first period being the Tonian, and the second one is called the Cryogenian period. There aren’t a lot of videos on these time periods, but are still worth the research.

Some kind of phreatic blast happened at one of the yellowstone geysers recently - you gonna cover that? If yes, I'll wait till your typical non sensationalist style vid comes out to learn about it. There are a couple outfits that have posted something - but you are my preffered source for anything interesting geology wise...
Can you talk about the fact that major earthquakes can actually occur in the region and Oklahoma and the fact that Oklahoma could actually have a big earthquake
I have a question. Is it still possible, not likely or even probable, for a lava flood to still occur, or has earth changed in the millions of years since the last of these events occurred?
The most recent flood basalt (Columbia River basalts) occurred from 17-6 Mya, so I don't think there's any reason that another one can't happen. Someone counted 11 in the past 250 million years, including undersea ones, but I think we've got a good supply of other things more important to worry about.
It's definitely still possible we have evidence that these kinds of Large Igneous Province flood basalts have been occurring since the late Archean eon. Many of the old ones are poorly understood as they are either fragmentary pieces which didn't subduct entirely due to their thickness or are the exposed roots of igneous dike and sill complexes which fed these eruptions. LIPs of this sort appear to play a key driving role in the supercontinent Wilson cycle so presumably as long as plate tectonics continues as we know it flood basalt LIPs will occur into the future acting as the primary drivers of supercontinent break up events. In many if not all cases the magma chemistry of LIP's indicates that the melts which feed these eruptions contain material derived from subducted slabs that have sank into the mantle and undergone or are undergoing multiple recrystallization phase transitions eventually becoming incorporated into various Low Sheer Velocity Provinces found at or near the core mantle boundary where they become reincorporated into the bulk planet. Depending on what measure you use to classify LIPs you seem to get a frequency interval of LIP's around 30 million years on average with the most recent large Continental flood basalt's activity being the Ethiopia Yeman flood basalts which had 4 main stages dating between 31 and 25 million years ago, If the Columbia river basalt group is counted then the interval is even shorter as newer dating constrains the Columbia River Basalt group's main eruptive activity to 16 Ma within a much narrower window of time i.e. many tens of thousands of years. Thus I think we have more than enough evidence to suggest it statistically isn't a matter of if but when the next LIP comes as it would be strange if they suddenly turned off abruptly after at least 2.5 billion years of flood basalt activity especially since the processes believed to be responsible for driving their formation remain active to this day. Note that the interval time depends on how many LIP's there have been which is hard to say with any certainty as the rocks of many suspected LIPs or even confirmed LIPs remain understudied. For example it appears that there are multiple mantle plumes which have links to several LIP's such as how the High Arctic Large Igneous Province and North Atlantic Large Igneous Province both seem to be linkable to the Icelandic hot spot as it has moved through the Arctic from Alpha Ridge with its lavas found in Svalbard norther Greenland and high arctic islands of Canada it has been implicated in initiating the slow break up between Greenland and Eurasia and North America starting in the Cretaceous before eventually driving the formation of the North Atlantic Large Igneous Province as the plume reemerged from beneath Greenland driving the separation of Greenland from Eurasia in the early Cenozoic at which point Greenland redocked onto North America. Modern Iceland began to form ~20ish million years ago but appears to be part of this same long lived system responsible for the creation of the Arctic ocean and the North Atlantic. Some researchers even hypothesize that by retracing this multi plume head plume system if that is what it actually is back in time though the volcanic and igneous rock record it has left through Greenland Canada and the Arctic Ocean that it may have been in the right place at the right time to be responsible for the formation of the Siberian traps too. I should note that this particular long lived hot spot trail seem to be composed of multiple pulses of LIP's with long lived LIPs seeming to be connected to ocean formation and rate of seafloor spreading such as how the Arctic Ocean has had seafloor spreading slow considerably after this hot spot track passed into what was once Laurasia but is now the North Atlantic.
Potentially Africa and the associated African Super plume complex lies beneath the African Large Low Sheer Velocity Province which appears chemically and paleogeographic ally connected to several flood basalt provinces as mantle plumes form along this supercontinent sized blob of material floating at the core mantle boundary. So for as long as Africa remains beneath the heart of this superplume complex yes there will be another LIP associated with this source which has been producing such mantle plumes of varying sizes for over 300 million years beginning with the Skagerrak-Centered Large Igneous Province. The current geological activity in the Albertine Rift zone responsible for ultramafic and or extremely alkaline volcanoes like Nyiragongo in the Congo or Ol Doinyo Lengai in Tanzania for example has even been suggested by some researchers to be linked to early partial melts from a new plume head still in the early stages of reaching the surface but I don't know how credible that interpretation is.
Oklahoma geologist here...appreciate your videos!
❤ from Oklahoma
Always have a good time when in Oklahoma, me & younger brother were adopted from a reservation there
I never thought it could happen there 😮

Were they still teaching flood geology back then?
Thank you. I enjoyed yesterdays explanation of Olivine and Granite as well as today’s Rhyolite and Granite. The heart of the matter.
I wondered about this more once over my years as a trucker.👍
happy to see you do another video on oklahoma
Thanks for all the hard work on these videos!

Hard to get worked up about something that happened half a billion years ago - 100 million years before terrestrial life even emerged.
Imagine all the potential gemstones in all of that.
Greetings from the BIG SKY of Montana.
Already early for the Biscuit basin video
I see there's been a hydrothemic explosion at Biscuit Basin at Yellowstone national park not long ago. Hopefully no one was hurt
Saw a video of it, didn't see any obvious signs of injury, though some people looked close enough that they might have been
@@mrexists5400 saw the same video and I agree.
You should report the Hydrothermal Explosion at Yellowstone National Park today
Any chance of a video soon on what happened at Biscuit Basin in Yellowstone Park today?
Also, what is the difference between a phyratic eruption and a hydrothermal explosion?
I want to know some news about the kiluea volcano. Recently I've been noticing that a bunch of earthquakes at a magnitude of 3.0 has been ongoing the past few days at the northern fault line
Did you see where a geyser in Yellowstone basically exploded? I think it was the biscuit basin geyser.
Please be making a video on the geyser explosion in yellowstone!
Imagine that happening today.
Thanks!
Didnt know how to contact geology hub. Did he hear about the yellow stone geyser explosion...above and beyond normal.
how about yellowstones black diamond geyser in bisquit basin..that is unusual
From Shawn Willsey's video it isn't that unusual beyond that someone was there to catch it on film. When precipitating minerals within those hydrothermal systems form a seal and allow pressure to build up high enough to break through the plug subsequently flashing to steam in the process of depressurization things get explosive.

And the wailing wheat sure smells sweet as it is burned by lava bombs falling like rain.
Could devastation like this happen if East Africa keeps rifting apart?
Potentially Africa and the associated African Super plume complex lies beneath the African Large Low Sheer Velocity Province which appears chemically and paleogeographic ally connected to several flood basalt provinces as mantle plumes form along this supercontinent sized blob of material floating at the core mantle boundary.
So for as long as Africa remains beneath the heart of this superplume complex yes there will be another LIP associated with this source which has been producing such mantle plumes of varying sizes for over 300 million years beginning with the Skagerrak-Centered Large Igneous Province. The current geological activity in the Albertine Rift zone responsible for ultramafic and or extremely alkaline volcanoes like Nyiragongo in the Congo or Ol Doinyo Lengai in Tanzania for example has even been suggested by some researchers to be linked to early partial melts from a new plume head still in the early stages of reaching the surface but I don't know how credible that interpretation is.
