This article gives the dates as 60-65 mya, but I thought the dates had been refined to around 68 mya, which is why the eruptions can not have been set off by a meteor strike 65 mya? Joe D (t) 17:45, 23 Jun 2005 (UTC)
The Deccan Traps began forming 65.250 million years ago,[2] at the end of the Cretaceous period. The bulk of the volcanic eruption occurred at the Western Ghats (near Mumbai) some 66 million years ago. This series of eruptions may have lasted less than 30,000 years in total.[3]″
So the bulk occurred before they began forming?? Weavehole ( talk) 23:21, 19 December 2014 (UTC)weavehole
This article begins with "The Deccan Traps is a large igneous province..." Should it not be "The Deccan Traps are a large..."? I'd change it myself, but I'm worried I'm missing something. Firsfron of Ronchester 20:00, 26 May 2007 (UTC)
I've just realized that the Deccan Traps formation happened in the same time frame as the K-T boundary extinction event (this is mentioned in the article). But one interesting fact is that the Deccan Traps are located at the exact opposite location as the Chicxulub Crater. Could it be that large meteoric impacts cause major volcanic eruptions at the opposite side of Earth? Maybe the Siberian Traps could be paired with a similar meteoric impact, although it would have to be located on the Pacific ocean bed. Finally, volcanic features on Mars seems to be diametrally opposed to large meteoric impacts. I'll try to find some research information on this topic (as I don't want to put original research on this page). 207.134.187.165 04:47, 12 June 2007 (UTC)
Chicxulub and the Deccan Traps were not diametrically opposite each other - neither was the antipode to the other. However it is possible that the impact at Chicxulub could have caused an increase in volcanic activity at the plume. Now some 65 million years later there is no means of knowing, so it will remain a hypothesis. Do large impacts cause volcanic eruptions may be but again we have no means of knowing. In respect of the Siberian Traps there is as far as I am aware no known impact feature which could feasibly be related. You need to remember too that the Deccan Traps were erupted over about 8 million years from about 68 to 60 million years ago, and the Chicxulub event occurred about 65 million years ago - roughly half way through the eruptive cycle. The Geologist ( talk) 15:19, 23 January 2013 (UTC)
Lava outpourings seem to be fairly consistent and anything can be proved theoretically - such as you and I have the same parents. However that is only a theory and the evidence from radiometric dating indicates that the Deccan Traps accumulated over about 8 million years which means that on average the rate of effusion was 0.25 of 1 mm per year. We do know that the process paused on several occasions from the evidence of palaeosols - fossil soils, animals that were trapped and plant debris. Similar things happen in the present time and we hae no reason to think that the Deccan Traps did not undergo a periods of eruption and dormancy. Think of Iceland at the present time, it is volcanically active yet it has periods of eruptive activity and periods of dormancy. The Geologist ( talk) 15:19, 23 January 2013 (UTC)
While this paragraph is not about India, the section heading here implies I might mention there is an equivalent huge basalt flow in Siberia, older than the Deccan Traps. And there is a huge crater in South Africa, the " Vredefort Ring", one of the biggest on Earth, of perhaps the same age as the Siberian outflow. I don't know how closely the ages match, and I certainly don't know if the two locations were antipodal at that time. But I don't know that they weren't, either. 216.54.28.10 ( talk) 15:34, 9 April 2010 (UTC)

A recent theory has come up that posits that the traps formed in as little as 100 years and caused the extinction of the dinosaurs, and that the dinosaurs were not killed by the massive asteroid impact. Is this worthy of inclusion?

I removed this nonsense picture. Nobody really knows how this extiction happened (if caused by Deccan Trap eruptions at all), but surely not the way depicted, dinosaurs writhing in agony under lava drops ... -- Jo ( talk) 11:59, 8 March 2009 (UTC)
If it is the picture shown here you are referring to, thenit most certainly IS NOT a plinian eruption. What the picture depicts is a lava curtain similar to those seen on Iceland - fissure eruptions such as the Laki eruption create lava curtains. The type of eruption depicted is hawaiian / icelandic style - effusive lavas with a very high dissolved gas content. The Geologist ( talk) 15:26, 23 January 2013 (UTC)
"Although, it has been suggested that the gases released in the process may have played a role in the Cretaceous–Tertiary extinction event, which included the extinction of the non-avian dinosaurs, the consensus among the scientific community is that the extinction was triggered by the Chicxulub crater." Not true, Gerta Keller, calculated that the extinction event took 2 million years, a kind of group censorship hides the truth. -- Chris.urs-o ( talk) 14:21, 5 March 2010 (UTC)
There have been proposed links to the Chicxulub Meteor Impact and the Shiva Meteor impact that occurred at or near the Deccan Traps Eruption.
=== Link to Chicxulub Crater ===
The Chicxulub Meteor impact has been endorsed as the primary cause of the mass extinctions at the end of the Cretaceous period, at the boundary with the Tertiary period. However, it has been proposed that the violent volcanism at the Deccan Traps may have been stimulated by the Chicxulub Meteor impact, causing a combined climate armageddon and mass extinctions. The proposed mechanism arises out of observations of the mapped surface of Mars. Mars has its largest Meteor impact crater (Hellas) almost diametrically opposite the only large patch of volcanos on Mars (Including the biggest - Olympus Mons) on the other side of Mars [1]. This evidence supports a mechanism where meteor impact shock waves travel through and around the Earth, to focus on the other side causing fracturing and uplifting of the mantle and possibly magma. The volcanos on Mars are pre-dated by the meteor bombardment. The Chicxulub impact was oblique, from South to North, so the focusing of shock waves could have been also in the Northern Hemisphere, at or near enough to the Deccan Traps to stimulate a super-volcano.
Viewed yesterday a conference by Vincent Courtillot where he stated that the Deccan traps started forming before the Chicxulub Meteor impact. I cannot give precise references, but the specialists could certainly do so. -- Olivier Debre ( talk) 09:27, 20 October 2011 (UTC)
The Deccan Traps are known to have been in an eruptive state and these are the oldest known lavas. The youngest known lavas have been dated at 60 million years whilst the Chicxulub impact has been dated at 65 million years - roughly mid-way through the eruptive cycles of the Deccan Traps. Whether the impact accentuated the eruptions is impossible to know. The Geologist ( talk) 15:31, 23 January 2013 (UTC)
I removed the addition above from the article because there are no references supporting the claims. The reference there is only support that there is a huge volcano on Mars. -- Fama Clamosa ( talk) 09:50, 6 March 2010 (UTC)
The article states that Keller supports the hypothesis that the extinction may have been caused by both the [Deccan] volcanism and the [Chicxulub] impact event. This is wrong. As quoted by The Atlantic [2], Keller rejects this hypothesis. “It’s impossible[.] They [Renne et al] are trying to save the impact theory by modifying it.” -- 92.219.24.183 ( talk) 23:36, 13 August 2018 (UTC)

I've been adding {{ weasel word}} and {{ by whom}} as I'm reading this but it makes more sense to ask if the text in general can be cleaned up, rather than pointing out every instance. So, if you have time and are knowledgeable, can you please review the text for places where opinions/ideas/claims are expressed without mentioning the person that expressed them? — SkyLined ( talk) 12:00, 24 November 2022 (UTC)
If you follow the Math of the Growth and Expansion of Planets, then the Deccan Traps was about 2 degrees south of the Equator 66 million years ago. and Chicxulub Impact site was about 2 degrees North of the Equator. The differential opening up of the Pacific compared to the Atlantic has not kept the two locations 180 degrees apart in the Last 66 million years.
It is more than 180 degrees apart across the Pacific, and less then 180 degrees apart across the Atlantic, using the Equator to North Pole Longitudes.
The fact that the Deccan Traps may have started 68 Million Years ago does not mean that the impact at Chicxulub did not affect the total volume of Magma. It is the second largest Magma Volume on planet Earth. The Largest Volume was the Siberian Traps that was Antipodal to the Wilkes Land Impact site in Antarctica.
Impacts reflect and refract energy waves to an antipodal point 180 degrees away from the Impact site in all direction, and re-focus the energy into a small area on the opposite side of the Earth. This is similar to a large caliber bullet impacting a thick steel plate. A crater forms on the near side, and a bulge forms on the far side of the plate. 165.127.60.132 ( talk) 21:01, 22 February 2024 (UTC)
