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



Dear Lin,

Those are nice maps. But the hotspot map reflects the thinking of the current theory.

I sent an email on 1/30/2014 that detailed my reasons for believing that the Sunda trench was a transform fault that has mostly been changed into a convergent fault. This email also includes the rationale for Including Lake Toba as the site of one of the world's largest mantle plumes. I include this analysis in my new book, as well.

You say that there is no hotspot located below India. That was the point of my argument. There should be a hotspot there, or at least a hotspot located where it was 60 MYA when that hotspot emerged from underneath India's west coast. The maps at the end of Chapter 2.2 of my book detail how this slower moving hotspot has moved more slowly but in a similar direction as India during the past 60 million years.

You write about building on other people's work. I do that as is appropriate. In particular, in this area, I use the work of and cite Dr. Hetu Sheth and his detailed geological work on India. I have 138 footnote citations in my book.

However, when one is going into an entirely new direction, there is often scant work to cite. Who would Copernicus have cited?

The relief map of the Indian Ocean shows many undersea features, but it does not have "inarguable tracts in oceanic crust that clearly show the direction of India's movement," as far as I can tell. If there is more to this, I would like to read about it.

Regards,

Ben

Firstly, Indonesia is a subduction zone. See my hotspot map: https://www.google.com/maps/d/edit?mid=z-9zS62AsqVY.kFcSYz-fB3Uk

There is no hotspot present.

Secondly, this is a map of the Indian Ocean floor. If you can't see it, then I can't help you to see it.

​Third, there is no record of a hotspot below India. No scientific papers. Nada. ALL research is furthered by the findings of previous researchers. Didn't Newton say it... standing on the shoulders of giants? You stand by yourself and that's not how science evolves.

So, I'm done. Again. Sigh. Ben, I do not want to insult you, but you can waste your life chasing phantoms and I would not like to see that happen to you. I wish you well.

I am not aware of "inarguable tracts in oceanic crust that clearly show the direction of India's movement." I would appreciate a reference to this phenomenon so that I can read about it.

But, what I can do is to point out what is missing from the oceanic crust regarding India's movement (according to the explanation of the current theory). Where is the sequence of seamounts and volcanic islands that should have been in evidence on the sea floor as India pulled away from the plume that caused the Deccan traps?

The eruption at the Deccan traps spewed out 27,000 cubic miles of volcanic material ... far greater than all other individual eruptions except for the eruption of the Permian-extinction-causing Siberian traps 250 MYA (which, by the way, was the only other plume eruption that did not exhibit domal uplift). The volcanic activity did not stop there. As India raced north (at the puzzling speed of three times the usual rate of tectonic movement ... but explained in chapter 2.2 of my book) the western side of the peninsula was pushed up and under girded with vast intrusions of volcanic material. This activity was so extreme that the entire peninsula of India slopes noticeably from west to east and all of its rivers run in this direction.

The speed of the movement of India did not allow the hotspot to break through to the surface along the western edge of the peninsula. The hotspot was not located below any specific area long enough for this heating and doming process to fully take place. Nevertheless, the hotspot continued to pump out prodigious amounts of underlain volcanic material until it reached the end of the tip of the Indian peninsula.

At this point, if you believe the current theory, the hotspot activity abruptly stopped. Really? Here we have the second biggest hotspot known to the science of geology ... it produces 27,000 cubic miles of volcanic material at the Deccan traps ... it produces prodigious volcanic intrusions along the entire western side of India ... and then it just stops.

Does this sound like any hotspot that exists in reality?

If you look at this scenario from the point of view of my theory, there is a pattern of hotspot continuation, involving the creation of the Indonesian Island chain (only the western side of Java and Sumatra), starting in the east from Timor and moving up to and through Lake Toba in northern Sumatra (with the Mount Sinabung area to the northwest as its likely current location). The Indonesian Island chain is the most volcanically active area on Earth ... just what you would expect from such a prodigious hotspot.

The sequenced illustrations at the end of Chapter 2.2 in my book show this continuation clearly.

I agree with Kim's common sense approach to the laws of physics, as well as to say, if India moved to the west, then what made those inarguable tracts in oceanic crust that clearly show the direction of India's movement?  I'm not going to argue with a signpost, but what you are suggesting is doing just that.

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.

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!
