Re: [Geology2] Fwd: Meteorite Impact May Have Triggered Largest Pulse Of Deccan Basalt Eruptions



One problem I can spot right off the bat is your area of uplift as you describe it fails to account for the dispersion of the energy of the impactor as if it would have remained narrowly focused all the way through the Earth to the far side and as if it were a larger object than it actually was... not that antipodes don't exist but this was not a large object relative to the size of things which have struck the Earth previous to the K-T Event.

The big problem here is that the current theory says that, unlike Australia and Antarctica, India moved to the north. I say that it moved to the west, along with Australia and Antarctica, putting it at the antipode of the Chicxulub impact 65 MYA. As far as I can tell, the only reason that the current theory creates this anomalous movement for India is that this movement goes along with the idea that the Deccan Traps were formed when India moved over the Reunion hotspot on its way to its present location.

However, if the Reunion hotspot were the source of the Deccan traps, then we would expect to see domal uplift of the area surrounding the Deccan traps. There is no domal uplift, as reported by Dr. Hetu Sheth, after extensively studying the situation.

The only way that the Deccan traps could create a nearly circular footprint along with no domal uplift would be for the eruption to funnel up through the pulverized rock at the antipode of a very large impact ... the Chicxulub impact ... which created a mantle plume that was large enough to include the physical antipode within its range. The magma would follow the path of least resistance and flow through this circular antipodal weakness, thus eliminating the need for several million years of domal uplift.

There are many points of evidence showing the movement of India as it moved from its position at the antipode of the Chicxulub impact 65 MYA to its present location, as detailed in my new book, www.solvingthemassextinctions.com.

The big problem here is that India was not leven ocated at the antipode of the Yucatan Peninsula. It was nowhere near it. Look at the maps of the time period. That in itself refutes your theory.

Just because the current theory doesn't understand that India was located at the antipode of the Chicxulub impact doesn't mean that it is right. The other three large impacts of the past one hundred million years showed contemporaneous mantle plume activity at the energy antipode (located close to the physical antipode). There is plenty of evidence indicating that the Chicxulub impact followed suit.

But Ben... didn't you see what the blogger wrote?


Be careful here. The impact did not initiate Deccan volcanism. That was caused by India rifting away from Madagascar (88 mya) and Seychelles (66 mya). The rifting and an unusually hot mantle underneath resulted in copious amounts of melt being generated in the mantle which found its way to the surface via the great tensional cracks formed when continents separate
​.​


​Your theory has already been refuted, seen by many peers, and accepted. To continue with linking the two events by applying causation to the bolide is folly.

I'm sorry, but you're beating, not a dead horse, but a non-existent one.

No. They still have more work to do. But they are getting closer!

Ahhh, now there we go! That makes more sense! I don't believe much in coincidences and it always seemed odd these two things happening nearly at once in a geological context. However, folks kept saying they didn't match up perfectly in chronology which stretched credulity for me. However, advocates for a causative relationship lacked proof.... and the time correlation has been better constrained and a mechanism offered. Nicely done!
