Previous studies have shown that while the eruptions in western India's Deccan Traps
began a few million years before the extinction event, volcanic activity surged closer to the time of the asteroid collision.
But some experts insist that the impact was a red herring and the real reason for the mass extinction was a surge of volcanic activity in a region of India known as the Deccan Traps

A primeval volcanic range in western India known as the Deccan Traps
, which were once three times larger than France, began its main phase of eruptions roughly 250,000 years before the Cretaceous-Paleogene, or K-Pg, extinction event, the researchers report in the journal Science.
Washington, December 9 ( ANI ): Volcanic activity from the Deccan Traps
in India, not a meteorite impact, may have killed the dinosaurs, according to a new study.
Drishnaswami through clever use of natural radioactive and radiogenic isotopes and selected elements have been able to investigate the details and determine the time scales of chemical scavenging and solute-particle interactions in the sea and ground waters, sedimentary processes on the sea and lake beds, growth and turnover of ferro-manganese deposits, river-ocean interactions and material transport through estuaries, air-sea gas exchange of CO2 and erosion of the Himalaya and the Deccan Traps
on the chemical and isotopic evolution of the oceans and long term global change.
And we don't mean the volcanic eruptions of the Deccan Traps
in western India that scientists believe led to the extinction of dinosaurs millions of years ago, but to the two volcanoes in the Andaman Sea -- one of which is now in a state of eruption -- that have the potential of becoming major tourist attractions.
Drawing upon an understanding he developed with respect to the East African Rift System and the underlying rifting and extensive petroleum and natural gas deposits associated with the Siberian Traps, Herndon predicts the extensively rifted region beneath the Deccan Traps
of India will become the site of important energy-resource discoveries.

Today, these flows, known as the Deccan Traps
, are delimited and interbedded by a sequence of sediments referred to as infratrappean (before trap), intertrappean (between trap), and supratrappean (after trap).
16 In which country are the Deccan Traps
, the remains of a huge volcanic eruption which may have raised global temperatures by as much as 8 degrees Celsius?
The investigated area has granites of Archaean age and is unconformably over lained by the Deccan traps
with intertrappean beds.
