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

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!
