[edit] Dates

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)

Dates for the Deccan seem to span the range from 68 to 60 Myr with some dikes dated at 70 Myr in the refs I've seen. I've tried to modify the article to clarify this, but need to do more. Vsmith 20:42, 23 Jun 2005 (UTC)

[edit] Is or are?

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)

[edit] Large meteoric impacts and super-volcanism: causality?

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)

As you can see at Cretaceous-Tertiary extinction event, the main pulse of the Deccan Traps eruptions preceded the Chicxulub impact by about 1.7 million years. Also, although it is difficult to find good maps that show the likely paleolatitudes and paleolongitudes, Chicxulub and the Deccan were not really very close to antipodal - they were separated by on the order of 130 degrees east-west (not 180) and on the order of 30 degrees north-south (not 90).

Thanks for giving these very useful details. I guess the link between super-volcanism and meteoric impacts is very hard to find... if there is any! Cheers 207.134.187.165 07:42, 15 June 2007 (UTC)

[edit] Map

Would be nice to have some kind of map... AnonMoos 20:36, 20 October 2007 (UTC)

[edit] Venus

I'm removing the lame and very tenuously related small section discussing Venus. It might deserve a small mention in the flood basalt article, but not here, not as presented. --Kbh3rdtalk 03:30, 20 January 2008 (UTC)

[edit] Cuddapah traps

Wonder if someone can also add information on how this relates to the nearby Cuddapah traps. Shyamal (talk) 05:05, 8 March 2008 (UTC)

[edit] Coordinates

Just checked on Google Earth, and 43-47 E puts you in Saudi Arabia. —Preceding unsigned comment added by 128.135.169.252 (talk) 08:32, 13 March 2008 (UTC)
