Summary: TEHRAN (FNA)- Scientists have obtained more precise dates for the
Deccan Traps volcanic lava flows, linking peak activity more closely to the asteroid or comet impact 66 million years ago and the coincident mass extinction.
He was part of a team that dated the vast lava flows known as the
Deccan Traps in India using radiation measurements.
But scientists have also pointed to another culprit: the
Deccan Traps in present-day India, one of the largest volcanic provinces in the world, which just happened to be going gangbusters at the time of the extinction event.
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 real reason for the mass extinction was a surge of volcanic activity in a region of India known as the
Deccan Traps.
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.
Earth has seen few volcanic eruptions of this magnitude, but notable examples include the
Deccan Traps, which erupted 65 million years ago and spread in a single eruption 9,000 [km.sup.3] of lava across much of what is now India.
The research argued that tens of thousands of years of lava flow from the
Deccan Traps, a volcanic region near Mumbai in present-day India, may have spewed poisonous levels of sulfur and carbon dioxide into the atmosphere and caused the mass extinction through the resulting global warming and ocean acidification.
