Thank you for posting this. A lot of people don't realize there is a huge geological feature right in the US: the transcontinental rift. It eventually failed, but it extends from at least Arkansas up to at least Lake Superior, then tends east then southeast, extending down to Alabama. At one point there were huge fissure/flood basalt eruptions. The rift is considered a large igneous province. en.wikipedia.org/wiki/Midcontinent_Rift_System
This is a fantastic overview. Despite reading plenty about historic flood basalts, my mind just couldn’t wrap around the scale and mechanisms behind it. Your imagery and concise explanation helped so much!
I saw a geologist talk a while back about the Deccan traps possibly being related to the dinosaur extinction but I haven’t been able to find it lately. Basically he said the meteor itself probably wasn’t big enough to cause such an extinction and life above Colorado would still be alive. The deccan traps could have just made it too hot and dusty for life to survive and acidified the oceans. We have no problem attributing the previous major extinction to the Siberian traps, but for some reason we have been only focused on the meteor impact because of the iridium layer. I actually get needlessly annoyed now whenever I hear “the meteor that killed the dinosaurs” in so many different documentaries with no mention of the Deccan traps lol.
The term "trap" has been used in geology since 1785-1795 for such rock formations. It is derived from the Swedish word for stairs ("trappa") and refers to the step-like hills forming the landscape of the region.[4] from wiki
They weren't, really. Chicxulub is only 16,000 km from Réunion -- short of the 20,000 km between antipodes. And they were closer 65M years ago, since the Atlantic has spread some since then.
Yes, Rudi. 30 years ago I was taught that the Deccan flood basalts might have been triggered by the Yucatan meteorite event, too, but I have to agree with Bill. The data seems to contradict that hypothesis.
The Siberian traps have always interested me, but without this, dinosaurs would never have ruled for 170 Million Years. However. I feel bad for the animals who had to live in such a hellscape, such as the gorgonopsid Inostrancevia.
confused.. lecture says the siberian traps are the largest volcanic event in the last 500 million years, but you also say the CAMP occurred 200 million years ago but that it is the largest flood basalt ever..?
The explanations for the flood basalts at the time of the breakup of Pangea and the Deccan Trap basalts are rifting, yes? And we still have the mid Atlantic rift, and there is another in the Pacific. But what is the explanation for the eastern Washington flood basalts? There is no rifting there.
The Columbia River Basalts are related to the hot spot under Yellowstone today. The fissures through which the flood basalts flowed are a zone of weakness that marks the ancient boundary of N American plate and where exotic terraces converged. These mantle plumes and hot spots are stationary and the plates move over them.
the columbia river basalts are a complex thing. there are ties to the yellowstone hotspot and the subduction of the east pacific rise and the interplay between the north american craton and the exotic terranes of the pacific northwest. flood basalts arent always tied to rifting. siberian traps happened in the middle of the craton, for example. they do seem to always have ties to hotspots when they emerge or re-emerge(like yellowstone following the subduction of the pacific plate)
I am staying in Deccan traps.... occasionally we see some hot magma flowing around in the Western Ghats near Pune.... one shiv sena leader was drowned too
Impact induced LIPs is appealing hypothesis. Sadly for now, not enough evidence. For example: deccan traps eruotion started well before impact. As for Wilkes land is still not confirmed as impact site. We're unable to confirm its age also, for now. It's appealing, but not more. For me: I would be very excited if impact induced LIPs were a real deal. That would be astonishing.

great lecture and great video. also itz fantastic where you put your own live person at the small corner instead of a big dead center--as other, self-worshipping people do. btw/ thr first flood basalt was over FOUR continents: Europe, N. America, Africa and S. American. you describe it, but you say "3 continents" by including Europe with Africa. pls dont.
flood basalts are extrusive, ie erupt at the surface and grow by successive layers being deposited on the ones below. the bushveld igneous complex is not a flood basalt, it was intruded at depth as a magma body. the layering was produced by a process known as differential crystallization.
It is not helping that you make yourself visible in the lower corner of the screen. It is just annoying (to me because it is vain) and it blocks some interesting information at times. So, unless you can't resist showing yourself without any obvious need to do that (like trump), your lecture would be even more interesting to me if you disappear when talking. Thanks.
The 5 you are referring to were at the time of the great flood of Noah's day. And with that your science is correct. But it was not that long ago. And that should be a wake up call.
Don't you just love science .... that knows precisely what happened 250 million years ago .... without a doubt .... then they find a rock that they can't explain and they Ignore it ... like it don't exist .... Like the polystrat tree that has roots in cambric and branches in preumbrian ... which an enigma ... oh my i just forgot ... e=mc2 ...

Its weird but flood basalts and magmatic provinces and any talk of massive volcanic eruption amd I am always reminded of the Land Before Time.
I live in SE Oregon where flood basalts created our landscape. Great lecture. Thank you.
I've driven across the Columbia River Basalt portion that is in Washington and along the Columbia River. It is awesome.

The timing suggests that the Deccan eruption was triggered by chicxulub, which was antipodal.
They weren't, really. Chicxulub is only 16,000 km from Réunion -- short of the 20,000 km between antipodes. And they were closer 65M years ago, since the Atlantic has spread some since then.

So interesting- loved visiting the Ellora caves carved out of this lava
He said hot pockets...I love those damn things. They taste awesome. Great video!
Are there anywhere in the world where flood basalt eruptions can occur now or in the future?
Probably Africa or Far-East Asia.
Iceland could have a... Tiny flood basalt. The eruption of Laki was a series of rifts that erupted in 1784.
To my knowledge it could happen anywhere in the world? Probably not anytime soon though
Rio Grande rift in New Mexico has some small recent basalt flows.
Where ever there is a diverging fault . Ie Africa's rift valley . State of Nevada is getting spread wider ?
i wonder if the basalt plumes start a one specific spot on the core. ?
confused.. lecture says the siberian traps are the largest volcanic event in the last 500 million years, but you also say the CAMP occurred 200 million years ago but that it is the largest flood basalt ever..?

Hot spots - Hawaii and Yellowstone on a larger scale.
@@allangibson2408 Specifically the Yellowstone hotspot, which the North American plate has been overrunning for the last 15(?) million years.
@@wwoods66 Longer than that (the trail winds up into Oregon) but Yellowstone tends to be more explosive than flood basalt.

Hello from New Zealand 🌱🌏💚
Your map doesn't show the Canadian Shield.
Is that from a basalt eruption?
I am staying in Deccan traps.... occasionally we see some hot magma flowing around in the Western Ghats near Pune.... one shiv sena leader was drowned too
Still some volcanic activity then, eh? Interesting. I would have thought it would be extinct by now.
I thought the Bushveld complex had been determined to be caused by an ancient very large asteroid impact.....
West coast California. Today. Basaltic flood eruption
Would that be around the Long Valley Caldera volcano area by Mono Lake... do you think?
The Deccan traps where most likely created for the Chicxulub impact.
Because the syberian traps where created by the the Wilkes Land impact.
