Deccan Trap Map

Caption

Once three-times larger than France, the Deccan Traps were a primeval volcanic range in western India that pumped Earth's atmosphere full of climate-altering carbon dioxide and sulfur dioxide at the end of the Cretaceous period. Princeton researchers analyzed sediment trapped in Deccan lava flows -- the largest flows on Earth -- near Rajahmundry in the Krishna-Godavari Basin, the remnant of an ancient sea on the Bay of Bengal coast.
