    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.

    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.

    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 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.

    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

    The timing suggests that the Deccan eruption was triggered by chicxulub, which was antipodal.

    • @wwoods66
      @wwoods66 3 роки тому +7

      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.

    • @kwgm8578
      @kwgm8578 3 роки тому +6

      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 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.

    • @michaellesak6912
      @michaellesak6912 3 роки тому +1

      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)

      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.

      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.
